AUTHENTIFYING METHOD

Abstract: An authentifying method is revealed which uses as an identification feature images, tokens, texts or sounds which are based on individual knowledges and experiences of a person (PSPI) and which consist of a principal part and a complement or of associated notions, with that person performing the following steps with regard to a plurality of these PSPI: first register them within a memory and keep them inaccessible to other people, secondly make them visible or audible without the complement and in a sequence which other persons cannot foresee, thirdly restore them with the missing complement or verify them; or first subdivide them into their associated elements and assemble and register the latter ones within a plurality of element groups according to superordinated categories of these associated elements, whereby the elements may be accompanied by tokens like numbers or letters, secondly make them visible, audible or available in their subdivided form according to the groups, for the elements of one category in a determined sequence and for the elements of the other categories in a random sequence, thirdly and still in subdivided form, put them together into characteristic two-dimensional structures or linear chains, by means of connecting associated elements of the respective element groups and of connecting these reconstituted PSPI in a sequence which is defined by the way in which the elements were registered, made visible, audible or available, or by the inherent nature of the elements.

Description: Authentifying method The purpose of the invention is to reveal a possibility of implementing with simple means authentifications which are falsification-proof and pleasing in application. There are essentially two types of authentifying methods: the first type consists of eqipping the person to be authentified with a person-unspecific characteristic, for instance with a password, a chip-card or a codified key. This characteristic being verified for authencity through comparison with a conform or a matching counterpart, checking for equality or for matching quality (lock and key system) . For instance, anti-theft devices of cars can be deblocked with a key containing a microchip, which exchanges a modified code with the motor control device after each use, as soon as the key is introduced in the starting switch. Only if key and car motronic are matching, the car can be started. The disadvantage of this first type of authentifying methods is that third persons may usurp the person-unspecific characteristic in order to unperceivedly occupy the wrong identity. The issue of memorizing numbers or passwords as a characteristic, is often not opportune because of human oblivion. Furthermore, third persons could get knowledge of these numbers and passwords during an authentification process. The second type of authentifying methods relies on the principle of preserving certain person-specific characteristics at a place remote from the person concerned. The proof of authencity is implemented through comparison of the original characteristic with the preserved counterpart. In the case of biometrical authentifying methods, certain physical features like hand-geometry, finger-prints, photographs or peculiarities caused by physique (like speaking specimens) , are in principle used as person-specific characteristics. Biometrical methods are complicated, partially susceptible to falsification, and are often perceived as embarrassing by the persons concerned. The present status of technology is described in the following patent applications or patents. • PCT/KR92/00056 (WO 93/09621) : An electronic identification system consists of first a portable device, which is activated after the introduction of a password, possibly in connection with the number of the car license plate, an account or identity card number, and secondly of an automatically responding control station. For the purpose of user authentification or for release of a certain effect, signals and information chains are exchanged by wireless transmission which are verified in both units. In one arrangement, the input device is equipped with only four buttons, two of which serve for scrolling forward or backward characters appearing on a display, a third one for marking certain characters, and a fourth one for undoing wrong markings. • DE-OS 42 20 971: For the purpose of an identity check, the finger-print of a person is photographically registered, transformed and preserved, and used as an identification characteristic. • DE-OS 41 25 870: Identification data of men or animals are attached to a tooth in the form of an active medium, so that these informations can be recognized in a non-destructive way at a later check-up. • DE-OS 41 07 042: A tubule is incorporated in a living creature, for implantation of information-carriers by which the living creature can be identified. • DE-OS 40 39 646: In the case of a biological object, measured values - for instance the electric brain or muscle activity - are recorded and compared with existing structures of measured values. Start or cancellation of a process are related to the result of comparison. • DE-OS40 36 025: Finger-prints are recognized by use of a hologra-mme. • DE-PS 40 09 051: A characteristic temperature distribution of the face is used as a biometrical identification feature. The possibility of using person-related values like voice- specific peculiarities (the spoken word) , tallness, shoe-size, the dynamic pressure course of movements, the structure of the blood-vessels of the retina, as identification characteristics, is mentioned. • DE-PS 40 08 971: The user of a data-station is authentified by passwords and random numbers via a one-way function. • DE-OS 40 05 448: For the purpose of partner search, personal data of a person, like character-traits, business and.private projects, interests and opinions, are preserved in a station belonging to that person, then transmitted to an analogue station of a potential partner, then compared with corresponding data of that potential partner which he/she may have re-transmitted, and then evaluated with regard to the degree of conformity. • DE-OS 39 43 097: Biometrically measurable data, for instance eye prints or finger-prints, are used as a key to accessing stored medical data. • DE-OS 38 34 048 and DE-OS 38 34 046: The finger-print of a person or a radioscopie of the finger-bone outline is used for optoelectronic identification of a person. The possibility of using supplementary measured values of identification like the form or outline of a nail, or solving of test problems, is mentioned. • DE-PS 38 27 172: Informations are identified by transforming an input information into an output information - dependent on preceding signs - according to the principle of associated individual transformation, whereby special ramification structures are applied. Informations of any kind can serve as the basis of identification, for instance completely unknown, unaccessible, non-reproductible random informations. The possibility of mutually exchanging information series between a data-carrier and the control station according to the challenge-response principle and of comparing those series with corresponding preserved information series for the purpose of identifying persons, is mentioned, whereby the control station will emit a "good"-signal if the comparison is positive. Furthermore, a portable memory is mentioned, into which a personal secrete identity number, an account number and other personal data are entered at the time of delivery to the owner. • DE-OS 3301 629: In a telephone office, informations are generated sequentially for each participant by a special switchboard, in order to identify a calling participant, such informations containing data with regard to the participant's address, number and the category to which he/she is attributed. • DE-OS 2846 974: A person is characterized by the solution of one or more dexterity tasks. • DE-OS 2 254 597: Persons are identified by the following process: members of the body having a characteristic curvature are recorded, preserved in the form of a curvature graph, and evaluated with a data treatment device. • DE-OS 2 224 667: A key has a recognition register with several indication elements which latter ones can be placed independently in two positions, each of which carrying indication symbols. According to the combination of the indication elements, different symbol patterns are being generated, one of them corresponding to a pattern of the key arrangement which is only known by the key-owner and which permits unlocking. • DE-AS 1762 669: In the case of transmission of informations, the calling participant transmits after the establishment of the connection two different characteristic qualifying signals, of which the second one is a coding of the first one. The other participant decodes the second signal and compares it with the first signal before the connection is getting operative. • DE-AS 1 195 057 and DE-AS 1 084 036: For the purpose of comparing persons, certain peculiarities of the face or of the entire body are measured or recorded, for instance the form of the ears, limit points of the temples, location of the pupils or of the nose tip, the middle line of the lips, the chin, particular wrinkles, cicatrices, birth-marks or warts. The use of poroscopie of finger- and palm-prints is also mentioned. • DE-PS 683 233: In the field of modus recognition services, the distance of two characteristic points of an object, for instance of a hand-writing sample or of a body feature, is opto-electronically juxtaposed to the corresponding points of an pre-existing pattern. • EP-OS 0 573 245: In order to check the intactness of messages in a communication network between a plurality of participants, a so-called authenticator is attributed to each transmitted message, that is a code which is calculated in the emission station from the entire information. In the receiving station, a comparison code is calculated from the received entire information with the same algorism. Only when both codes are conform, there is certitude that the message was transmitted intactly. Authentification of participants is implemented by secrete and non-secrete keys, and by different encoding functions and transmission steps. • EP-OS 0 548 967: In context with a data exchange system, mutual authentification is started by checking a personal characteristic, e.g. a codeword, entered by the user, after exhibition of an encoded dataword preserved in the system which is only known by the user and which can be modified by him/her. • EP-OS 0 532 227: In order to create unequivocal connections within a cellular mobile telephone network, authentification signals are generated by a key-code which is conferred upon by the network operator and later-on changeable. • EP-OS 0 522 473: Transscripts are generated between a person to be authentified and a central authentification instance, by exchange of certain secrete and non-secrete informations in a communication network, as well as by exchange of therefrom resulting questions and answers (challenge-response principle) which will be transferred in doubtful cases to an arbitration instance for renewed screening of the user qualification. • EP-OS 0 466 146: In order to guarantee that certain texts can only be read by persons who are qualified to do so, these texts or parts of them are composed of encoded signs which are preserved in a memory and which can be decoded by special methods. • EP-PS 0 441 774: An authentification card has several separate zones, one of which is dedicated to permanent preservation in encoded form of a person-specific singularity, for instance of individual peculiarities as finger- or foot ¬ prints, signatures etc., with the addition or abstraction of certain partial elements. The other zones are intended for temporary preservation of the same singularity without the additions or abstractions, for instance after impressing a finger or a foot, or by means of a scanning-process during authentification. An automatic comparison of both singularities is implemented in a card-reader, after reconstitution of the image of the permanently preserved singularity through a code entered by the authorized user. • EP-OS 0 382 410: in order to memorize and retrieve a password, its owner inserts the characters of this password into a plurality of alphanumerical texts according to a self- chosen pattern, in such a way that he/she alone is able to retrieve these characters with the help of the memorized pattern. • EP-PS 0 085 680: A data-carrier, preferably a personal card, containing informations about the owner, the conferring organization, account numbers etc., is introduced in a reading device for releasing a free-signal. For the purpose of a supplementary authentification, the finger-tip of the owner is scanned by a sensor, recorded as papillary-line information, and compared with a counterpart already preserved in the reading device. • EO-OS 0 082 304: A person is identified through voice- recognition on the basis of a characteristic sequence of voice peculiarities emitted during the pronouncement of a key-word, as well as through face recognition, e.g. through recognition of a specific part of it. • EP-OS 0 034 755: A qualification pattern consisting of characters and changeable by its owner, is preserved in encoded form in the recognition field of a qualification card. This pattern generates a protocol during the reading process which has to coincide with an authenticity protocol for authentification. • EP-PS 0 029 894: A key electronically imbedded in a personal identification card, being unchangeable and unrecognizable, is compared with a key in the possession of the person to be authentified. The possibility of using signatures or dynamic signals during signature, as well as voice-records or finger¬ prints, as person-specific characters for authentification, is mentioned. • EP-PS 0 007 002: For the purpose of user authentification and for transactions between a data station and a control unit, the former receives, combines, encodes and retransmits in a modified form certain user messages, and the latter receives these modified messages for comparison with preserved information. • EP-OS 0 006 419: Parts of the signature of a person are cryptographically recorded via certain keys, and decoded and verified for authentification. The task of the invention is solved by the authentifying method defined in the principal claim. In this context, the images, tokens, texts or sounds which are based on individual knowledges and experiences of a person and which consist of a principal part and a complement or of associated notions, and which are used as an identification feature, are denominated according to an appropriate terminology as person-specific psychometrical informations, abbreviated PSPI. Every human being is unique because of its course of life, that is to say, its experiences and knowledges. Everybody is in a position to form thousands of original associations which cannot be produced by other persons. Specific psychometrical experiments have shown that experiences can be reproduced particularly well, if they are remote in time, adapted to the human thinking structures, and closely connected with persons, places, times and quantities. Contrary to authentifying methods where third persons try to demonstrate the identity of a certain person, the method according to the invention is methodically a self- identification, that is to say a method where the interested person himself/herself demonstrates in face of third persons that he/she is really a definite human being. The well-known didactical methods like "interactive learning" on the computer, or "multiple-choice" tests are completely alien to the method of the invention. Those methods rely on the principle that the learner or examinee has to reproduce common knowledge and just not individual PSPI. The authentifying method according to the invention is distinguished by the possibility of using a very large number of PSPI as an identification characteristic. The PSPI which consist of a principal part and a complement or of associated notions, benefit from the fact that they can be expressed and treated, as bipartite structures (preferentially as couples of written or spoken texts) , in a particularly easy, clear and compact manner, thus with minimum investment in information units. Therefore, the method according to the invention can be realized in a particularly economic and safe way, opposite to the biometrical method. If the PSPI are submitted for the purpose of identification to the process steps defined in the second part of the principal claim, joint preservation of matching association elements is not necessary. In this case, groups of association elements belonging to a common category are preserved separately. Only in the last process step, the integral PSPI are formed from matching association elements, and the latter are assembled to characteristic structures. Concealment of these association elements being preserved as groupes, is therefore not absolutely necessary. This peculiarity reduces the investment for protecting the preserved PSPI against unauthorized access. The authentifying method according to the invention can be realized with existing simple and low-cost components. It has the potential of mass use in very different application fields like: • Traffic technology: anti-theft devices; • Safety technology: access control, equipment for surveillance and alarms; • Banking and trade: telebanking, electronic cash, personalized bank cards, productivity enhancement in the fields of check control and direct debit processes; • Communication and information technologies: authentification of participants; • Registration services: falsification-proof identity cards; • Cryptography: secrete keys, notebooks, PIN-cards. Particularly appropriate arrangements of the authentifying method according to the invention are described in claims 2 to 10. Several types of PSPI, advantageous for authentification purposes, are enumerated in claim 2. Short statements which can be seized by one glance (in particular a combination of two notions which are either true or wrong) are especially appropriate for representing the principal part of the person- specific PSPI, while a symbol for "true" or "wrong" is representing the complement. For instance, such statement could be: Principal part of PSPI: " Village A is located in county B", PSPI complement: "wrong". Contrary to other categories of PSPI, e.g. questions or text fragments to be completed, statements are especially simple, as only two different complements are possible, namely "true" or "wrong" . Such complements are susceptible to be entered very easily into the system, for instance through pushing one or two corresponding function buttons. Verification of one single statement is, however, not sufficient for a safe authentification: The probability for an unqualified person to accidentally pushing the correct button is 50%. Therefore it is proposed to verify a series of different statements rather quickly one after another, and to divide the total quantity of all preserved statements preferentially into 50 % true and 50% wrong ones. Thus the hit score for accidentally pushing the complement buttons by unqualified persons will be a minimum. For instance, if there are ten statements to be verified, the probability for an accidental authentification is only 1/ 2 10 or 1/1024. Claim 3 points to appropriate technologies for realizing the authentifying method according to the invention, and also to different advantageous safety measures. For instance, it is possible to programme the authentification process in such a way that renewed authentifications with new PSPI are automatically initiated in irregular intervals, if authentcards (chip- or magnet-cards intended for authentification) are kept permanently in an authentdevice (reading and data-treatment device for authentcards) . By these means, the presence of a certain person can be surveyed during longer time periods. It may also be opportune to exclude the faculty of authentification temporarily or definitively, by means of a time switch or an external signal. For certain applications, it is advantageous to update, replace or reproduce the preserved PSPI under observation of the necessary discretion, partially or integrally. The main system components for the implementation of the authentifying method are described in claim 4. For design reasons, the devices for the preservation and manipulation of the PSPI have often to be placed directly at the points of action. The necessary miniaturization of these components is not difficult to attain, especially if intelligent chips are utilized: 200 statements in text form with each about 25 characters don't need more than 5 kB of memory volume. In the context of the invention, an actuator is a device for the release of a distinct mechanical, electrical, optical or other effect. The object of claim 5 is a miniaturized unit assembling all essential system components, having a very simple design and being easily operated, which can be used as an electronic key in many fields. The arrangement according to claim 6 allows mutual tele- authentification of two persons who have exchanged their respective authentcard. Claim 7 reveals another arrangement at which the PSPI of a multitude of persons are entered and stocked in a central operational data bank, from where they will be transmitted - for the purpose of authentification and if required or during certain time periods - to decentralized control or teleoperated stations having a display and an input device. One advantage of this configuration is the fact that those to be authentified don't need an authentcard. The principle of concentrating the PSPI of a multitude of persons within a central data bank can be combined with the principle of authentcards. Authentification relies in this case on two complementary PSPI stocks, the one preserved in the card possibly being relatively small and interchangeable. Claim 8 reveals different characteristic tying-together schemes and arrangements of PSPI which consist of a plurality of associations of the type Ax-Bx-Cx etc. These schemes and arrangements can be used as authentification criteria which can be easily checked. In particular it is advantageous to arrange the association elements in the form of a matrix or of columns, and to attribute to them so-called basic-numbers BZ, from which for every arrangement "A" a characteristic result- number EZ can be calculated. The latter is, in the language of mathematics, function of all basic-numbers BZ and of their arrangement "A" : EZ = EZ (BZ* | _, BZ 2 BZ n , A) The function EZ can be defined by most different algorisms, for instance by: EZ = Sum of all (I x ) 2 I x = BZ x * BZ x+l * BZ x+2 The basic-numbers BZ are advantageously integer numbers, and the function is preferentially defined by algorisms which deliver as result-number EZ an integer number having many digits. Further criteria for the choice of an appropriate algorism are the following ones: easy implementation of the calculation, easy programming, and finally: impossibility to calculate the inverse function with limited calculation and time investment. Claim 9 reveals convenient technologies, system components and functional processes for realizing the authentifying method according to claim 8. If a large number of persons has to be authentified, it is advantageous to supply each of them with an individual authentcard, on which are preserved the names and first names of people who are in the first line only known by the corresponding person himself/herself, as well as basic- numbers attributed to these names, and the corresponding result-number. The tying-together of the names and first names is advantageously performed by means of an authentdevice with touch-screen, in which the authentcards can be entered. A complementary authentification on the basis of other personal characteristics can be performed in addition. Claim 10 reveals a tele-authentifying method with a so-called pocket authentdevice which allows authentification by telephone. A simple and falsification-proof tele- authentification can be implemented by: calculating an original result-number and a second result-number on the basis of a modified basic-number, transmitting the original and new result-numbers and basic-numbers, and comparing the new result-number with another one which is produced in a data treatment device. The pocket authentdevice is also suited for all kind of on-the-spot authentification, for preserving secrete codes and PINs or other personal data in an undecodable manner. The invention is more closely explained in the light of the following examples and with special regard to the attached figures 1 to 13. Example 1: Application of the authentifvinσ method in leσal informatics. The task may be to exchange confidential informations via fax between a person Pl at the site SI and a person P2 at the site S2. Two preferentially identical authentdevices, except for the preserved PSPI, are placed at the sites Si and S2. The device at SI has stocked the PSPI of person P2, the one at S2 those of person Pl. Both authentdevices may be connected via a digital network. Person Pl establishes the contact to P2 by operating a signalling apparatus. The device at S2 transmits stepwise ten texts from its memory to the device at SI, where Pl pushes the function button "true" or "wrong" after having checked each statement which appeared on his/her display. After identifying correctly all statements as true or wrong, an actuator of the device in S2 signals the authenticity of Pl. Hereupon, P2 initiates his/her authentification. This happens in the same manner as implemented by Pl, except for the fact that it is no longer necessary to operate the signalling apparatus, because the connection is already established. After P2 has correctly reacted to the ten statements, the mutual authentification is terminated, and the actuator of the device at SI deblocks the connection for the exchange of faxes. The total authentification will be accomplished in about twenty seconds. Example 2: Anti-theft device for cars. In recent years, theft of cars has become a big problem. Therefore it is getting more and more common to install anti-theft devices or immobilizers in vehicles. Such devices interrupt simultaneously starter, ignition system, injection or gasoline pump, and become automatically operative within about thirty seconds after locking. Only with a coded card or a coded key they can be inactivated for starting the vehicle. Professional car thiefε are, however, not discouraged by such systems: simple bridging or disconnection of the cables will make ineffective these systems in a short time. On the other hand, traditional anti- theft devices are of no value in the case of carjacking. The invention redresses that situation. The example regards an automobile with two miniaturized memory-units which are addressed from the same terminal. The first memory-unit Ml may be mounted at the gasoline pump, the second one M2 at the upper part of the coach. The terminal T may be incorporated in the instrument-board and connected with Ml and M2 via preferentially multi-core cables. Ml may directly effect the pump by means of an actuator, thus without intermediary electrical circuit which could be short- circuited. In the basic position, the actuator keeps the pump blocked, the pump drive turned off, and the gasoline supply interrupted. In the operational position, the actuator keeps the gasoline pump in operation. M2 may act directly, equally by means of an actuator, on a viewy and impressive signal, for instance a metal arm which is in the basic position of the actuator embedded in the coach, so that it cannot be seen from the outside. In the operational position, the metal arm is upwards directed. In the basic position, the metal arm blocks mechanically the vehicle. It is convenient to attach an identification mark of the vehicle-owner to the arm in a clearly visible manner. For starting the vehicle, the driver has first to switch on the electrical supply of the car, practically with a mechanical key system. By the same operation, the components Ml, M2 and T are being made operational. Next, the driver operates the signalling apparatus of T and thereby establishes the contact to Ml. Ml transmits stepwise ten statement-texts of its stock to T, the display of which exhibiting these statements. After appearence of each single statement, the driver pushes either the functional button "true" or "wrong" . If all statements are correctly marked (this will take about ten seconds) , Ml will release its actuator and with its help the gasoline supply. In a second step, the contact to M2 will be established, and the signalling arm will be likewise put in operational mode. The entire system composed of Ml, M2 and T is advantageously programmed in such a way, that the actuators will fall back into their basic position after the running off of certain time intervals. Further operation of the vehicle is then only possible after a new authentification. The time intervals are preferentially fixed by a device for the generation of not foreseeable random series of control impulses. In order to guarantee traffic security, some time will elapse after each turning-off impulse, until the actuators will fall back into their basic position. Example 3: Authentoard with application-specific integrated Chip (ASIC) : According to figure 1, a rather large quantity (e.g. 100) of PSPI statements are introduced (arrows 5) in the authentcard 1 with one-chip-microcomputer, observing the necessary safety measures, and are preserved in it, each PSPI with its complement "true" or "wrong" . A memory volume of about 1 to 10 kB is needed for this preservation. Because of mathematical reasons, an optimum is reached if half of the total number of the introduced PSPI statements is true, and the other half wrong. The internal structure of the card ensures that the preserved PSPI cannot be copied without authorization. The authentcard can be put into an authentdevice 2. By interaction between both of them, a sufficient quantity of PSPI (e.g. ten) are randomly released without the complement one after another, whereby it will be convenient if a subsequent PSPI appears only after complete handling of the previous one. It is, however, also possible to treat groups of PSPI simultaneously. The PSPI without complement are electronically transmitted to a display 3 (arrow 6) , where they get visualized. The card owner verifies or falsifies the PSPI one after another, by means of a push button 4 which may be supplemented by a second one. Experience shows that not more than about ten seconds are needed for this operation. The PSPI which are complemented in this way are sent back to the authentdevice (arrow 7) and compared with the original PSPI stocked in the authentcard (arrow 8) . If this check is successfully performed, a free-signal is released (arrow 9) . On the contrary, a stop-signal is released, preferentially after finishing the comparison (arrow 9) . In the case of a series of ten PSPI to be checked, the probability for a non- authorized person to correctly verify or falsify by chance the PSPI, is less than one' per thousand. The ASIC comprises: a long-time memory for preserving the PSPI and the programme routines, a micro-processor for implementing all necessary operations, in particular release of the PSPI without complement in a non-foreseeable manner, serial comparison of these PSPI when they are complemented, with the original preserved entire PSPI, generation of the free- and stop-signals and of the safety routines, and also a sufficient short-time memory. It is possible to transfer part of these functions to the hard- and software of the authentdevice. For the example with an authentcard just described and presented in figure 1, it would be possible, as an alternitive, to get along with a far smaller stock of PSPI (about ten) instead of the roughly hundert PSPI preserved in the form of statements, and still guarantee sufficient safety.: only a few PSPI (e.g. two) would have to be extracted from this stock per authentification, if PSPI in the form of question plus answer or in the form of text fragment plus missing text would be used. However, for this alternative it would be necessary to provide an alphanumerical key-board, by itself complicated and expensive, instead of the input push- button of figure l. Example 4: Memory-unit with actuator. Figure 2 shows schematically how the ASIC 1 is permanently incorporated in a stationary casing 2. This unit is equipped with an energy supply 3, an electronic connection 4 to the remotely placed display which is not presented, and with an actuator 5. This configuration is suited to serve as an electronic anti-theft device for vehicles, especially with the inclusion of the time factor according to claim 3. Example 5: Active authentcard. Figure 3 shows a miniaturized unit like an active authentcard which assembles all components and functions of an authentifying system. The casing 1 with dimensions of 10cm x 4cm x 0,8cm as an example, possesses a two-line main display 2 for visualizing: the PSPI without complement, the introduced complements, and other texts. In the light of the international Patent Application No. PCT/KR92/00056 (WO 93/09621) , the key-board can be reduced to a few buttons even in the case of alphanumerical input: The button 3 (up) initiates forward- and the button 4 (down) backward-scrolling of alphanumerical characters appearing on the auxiliary display 5. The authentcard is turned on by button 6 (on) , and the first PSPI without complement appears on the main display. The button 7 (set) serves for the input of the relevant character into the auxiliary display, the button 8 (cancel) for cancelling incorrect inputs. The result of the authentification process is visualized on the main display and enables the performance of certain supplementary operations, if it is positive. A miniaturized authentdevice of this kind can be used in numerous applications, for instance: a) as a crypto-notebook: Personal informations like secrete codes, account numbers etc., can be entered with the provision that they can only be reproduced after a successful authentification; b) as a falsification-proof identity card: Only the owner of the device is able to perform his/her authentification; c) as a key for access to otherwise blocked localities, plants, machines, vehicles, data systems. After successful authentification, an open-signal will be available. In the case c) it is convenient to suit the outer form of the device to the key-function. Such an electronic key can be programmed, as an example, so that codes, passwords or information chains which are preserved in the device and which may be time-dependent, can be sent to the lock after successful authentification, via contacts or other means not represented in figure 3. The codes, passwords or information chains are chronologically conform with their changing counterparts in the lock. The programme may also initiate a temporary or permanent inactivity of the key. The time-dependence of the codes, passwords or information chains in key and lock can be realized in many ways. For example, the digits z χ of a code-number can be recalculated in regular or irregular time intervals, each digit resulting from a distinct time-function which may be changeable after prefixed time intervals or through signals emitted from the outside. Such a time-function is defined, for example, by the formula: z χ = Mod[Int{Sqrt(n+a x ) } ,10] z χ •= integer number between 0 and 9 Mod = modul-function Int = integer-function Sqrt = square-root-function n = number of passed time-units a χ = constant value The constant value a χ has another value for each digit of the code-number and can be time-dependent itself. For reasons of safety, it my be opportune to conceal the preserved codes, passwords or information chains and their time-dependence from the key owner. Example 6: Authentmatrix. According to figure 4, at one axis of a chess-board like field, encoded electronic informations are input via a ten-bit-wide databus. The encoding principle consists in a far-going re-arrangement of the conducting wires of the bus (the conducting wires may be numbered as LEx at the matrix input and as Ax at the matrix output) . The following attribution is implemented in the example: LE0-I-A8, LE1-I-A4, I-E2- A5, LE3- A0, E4-LA2, LE5-LA9, LE6-LA6, LE7-LA1, E8-LA7, LE9-LA3. Each one of the ten conducting wires of the databus is marked with the name of a person. At the other axis of the matrix, the informations are passed on equally via an ten-bit- wide databus. The ten output conducting wires are marked with the ten correlated first-names of the persons, in such way that a mottled sequence of first-names is formed, if the names are passed one after another. Each input wire can be connected with every output wire within the matrix. Decoding of informations is implemented by re¬ arranging the wires in the matrix in such a way that each input wire is correctly tied-together with its correlated output wire, in the example: E8-I-A0, LE4-LA1, LE5-L-A2, LE0-LA3, LE2-LA4, LE9-LA5, LE6- A6, LE1-LA7, LE7- A8, LE3-LA9. The dashed fields in figure 4 designate the combination points of correctly associated names and first-names. The person to be authentified creates the ten correct contacts between the wires of the input-bus and the output-bus, through pushing of buttons or similar impulses on these fields. In total, there are 10! posibilities of tying-together the two data-buses within the matrix. Only one of them is the correct one, is therefore suitable to decode and pass on the fed-in informations. The principle of the authentifying method described in this example and outlined in figure 4, can be physically implemented in many ways. For instance, the two-dimensional pattern consisting of the ten nodal points, can be used as a mechanical or electronical key which matches with a lock not recognizable from the outside. Or it is possible to attribute to all matrix fields signs or numbers (basic- numbers) , whereby the signs attributed to the nodal points may serve as secrete codes, or the corresponding basic-numbers may be fed into a calculation algorism in order to calculate a result-number which is characteristic for the pattern. Example 7: Static PIN-Card. According to figure 5 and with a view of reproducing secrete codes (PlNs) , the owner of the represented card first produces ten couples of names (name 0, name l etc.) and associated first-names (first-name 0, first- name 1 etc.) of persons who are only known by himself/herself, in principle. In figure 5, names and first-names with equal digit are ________ correlated. The names and first-names are arranged on the card or on data-carriers to be fixed on the card in such a way that couples of names and first-names which belong together are placed in both columns in the most random manner. Then the card owner defines (in the example) five PIN-codes (C O, C l, C 2, C 3, C 4), or takes note of already existing codes each of which may contain up to ten characters. A digit or character (zOO to z49) of each of the five PIN- codes is juxtaposed to each first-name of the card or inscribed in special data-carriers, within five columns of digits or characters, in such a way that the first code digits or characters are placed beside that first-name which belongs to the first name, the second code digits or characters beside the first-name which belongs to the second name, and so on. If a code has less than ten digits or characters, digits or characters of any kind are inserted after exhaustion of the stock of digits or characters of the code. For the purpose of authentification, the card owner associates one after another the names with the first-names, and gets stepwise from the relevant column the code digits or characters which are placed beside the first-names. Example 8: Active PIN-Card. According to figure 6, the names and first-names of persons are used as association elements Ax and Bx. A display B and several handling buttons are placed on an electronic secrete-card A, abbreviated active authentcard. For example, the following buttons may be available: E for "on/off", F for scrolling the code- denominations, G for "okey", H for scrolling the first-names, I for the exhibition of the desired entire code. The arrow C symbolizes the input of the informations to be stocked: Names, first-names, code-denominations, characters or digits. The latter ones are a function of the first-names and the code- denominations, the order of exhibition of the names depends upon the code-denominations. For instance, the authentcard may be "loaded" by insertion in a loading device, through incorporation or programming of an intelligent chip, or by putting it together with a key-board or a personal computer. Arrow D indicates the possibility of utilizing a code which is generated during the authentifying process, for unrecognize'd authentification as in the case of an encoded key. For the generation of a PIN, the device is switched on, and the desired code-denomination is entered by scrolling and operation of the "okey"-button. Thereafter, the names appear one after another in the display. By scrolling the first-names and operation of the "okey" -button, the correct first-name is entered. Simultaneously the device is memorizing the correlated code-digit or character or visualizing it in the display. The entire code is thus reproduced stepwise. Example 9: Static PIN-Card. According to figure 7, ten text- couples Ax-Bx, composed of notions which are only within the remembrance of the owner, preferentially names and first- names, are inscribed in a card or leaf within two text columns in such a way that correlated names Ax and first-names Bx are separated from each other in a most irregular manner. For the purpose of illustrating the principle, the names and first- names of contemporary personalities are used in figure 7 which don't satisfy, of course, the fundamental psychometrical criterium of exclusive individual knowledge. Between these two word columns, eight double columns of signs are arranged, preferentially of letters and digits, from which eight secrete codes (PIN 1 to PIN 8) can be derived. In these central sign-columns, digit-codes are placed under the titles PIN l to PIN 5, and letter-codes under the titles PIN 6 to PIN 8. For reconstructing the eight codes, the card owner associates the names with the first-names (which are in real cases only within his remembrance) one after another as indicated in the left parts of the double columns by letter- or digit-series, and then comes within the right parts of the double columns to the digits or letters forming the secrete code, following the lines of the first-names. In the example, the following codes will result: PIN 1 = 36 29; PIN 2 = 29 26; PIN 3 = 27 305; PIN 4 = 69 11 37; PIN 5 = 57 06 27 98 18; PIN 6 = EGM ZUC; PIN 7 = GQA REH DZ; PIN 8 = AHO SUW DI BQ. Example 10: Personalized electronic kev. According to figure 8, a display 2 is incorporated in a longish plastic casing l, on which up to about 25 characters can be exhibited single- lined. By pushing the button 3, short statement texts are visualized one after another, in particular combinations of names, which are to be verified by the key owner, for instance through twice-repeated pushing of the button. After a determined number of verifications, an electronic signal becomes available for a short time via the contacts 4 which releases the intended effect after putting the key in a suitable electronic lock. The electronic system of the inherent ASIC consists essentially of a memory of about 500 to 1500 Byte volume and a processor for the release, the exhibition and the comparison of the preserved texts, as well as for the input, the preservation and the time-dependent release of the signal. A key-board which is seperated from the key, serves as an input device for the texts and, if needed, for a modified electronic signal. It will be put together with the key-board for the "loading" of the key. In order to activate the key effect, the key is put into a corresponding electronic lock. The main advantages of this personalized electronic key are: a) Only the key owner is able to activate the key. He/she needs not memorize any code or secrete number. Nobody can forge the key. b) The texts used for verification, and the signal can be exchanged. c) The key is suited for wide application, for instance as an anti-theft device for cars, for controled access to rooms and apparatusses, in general for all cases where non- personalized keys are now being used, d) Simple design with existing components. Example 11: Identity card. Fifteen text couples (Al-Bl, A2-B2, .... A15-B15) , logically belonging together, are noted within two columns of the identity card according to figure 9, correlated couples Ax and Bx being irregularly separated as far as possible. The tying-together of all the texts follows the scheme Al - Bl - A2 - B2, whereby A(x+1) is placed on the same line as Bx. The first fifteen prime numbers are arranged between the two text columns as basic-numbers, one after another. Notions which are only remembered by the owner of the identity card, are advantageously used as text couples, like names and first-names of persons, names and business of persons, names and denominations of localities, names of neighbouring villages, denominations and characteristics of locations, and so on. The fifteen basic-numbers BZ are brought into a particular order through the before-mentioned tying-together plan of the texts. In total, there are 14! « 8,7 x 10 10 different orders. It is therefore impossible to guess the order chosen for the identity card, and pointless for reasons of time and costs, to inversely calculate the order starting from the result-number. This is particularly true if one keeps secrete the calculation algorism, that is to say, if one does not note it on the card. Fifteen intermediary results N χ 2 are calculated by the algorism shown in figure 9, via the operandusses: N χ = BZ(A χ ) • BZ(A χ+1 ) • BZ(A x+2 ) and the power-exponent 2, for each order of basic-numbers. The final result-number EZ is found by addition of the fifteen intermediary results, in the example EZ = 2 042 071 872. It is obvious to use other tying-up plans, other basic- numbers, and other algorisms for calculating the result- number. The identity of the card owner will be demonstrated at a given time and a given location, by re-calculation of the result- number EZ. For this sake, an elementary pocket calculator is sufficient. It is also possible to use a specially programmed calculator, into which the fifteen basic-numbers are entered one after another, and which directly outputs the result-number. In this case and in the following one, the description of the algorism on the card can be dispended with. It is even more advantageous, to use a card-reader (a so- called ident- or authentdevice) , on the display of which texts and numbers are exhibited after introduction of the card, and on which the card owner can tie-together the texts (and numbers) with the provision that a programme contained in the reader will automatically calculate the result-numbers. In order to speed up the identification process in the case of institutions where a large public needs to be received at counters and cash-offices, for instance in banking for check- confirmation, in trading for automated debiting and for electronic cash, it is opportune to place the authentdevice remotely. The basic- and result-numbers of the identity card will be transferred by the authentdevice into a short-time data-carrier (so-called authent-money) which can be evaluated by a reading device placed near the counter or the cash- office. After a pre-determined time or initiated by the reading process, the data temporarily entered in the data- carrier will be automatically cancelled. If the authentification is to be effected by a remote instance, it is possible to enter and transmit the result- number, and the basic-numbers in the correct order, by means of the common and practically everywhere available numerical key-boards of the existing communication networks, observing appropriate safety provisions. In the example, it would be necessary to enter ten digits for the result-number and fifteen two-digit numbers for the basic-numbers. This does not require more effort than the establishment of international telephone connections. In order to improve security, the authentification can be subdivided in two or more steps, that is to say one can perform several identifications with the same identity card or with different cards, in a time-staggered manner. For instance, it is possible to use two cards which are nearly conform and which differ only by a very small rearrangement of the texts. If somebody would manage to spy out the first identification process, he/she would not be successful, as he/she would not be conscious of the fact that there is a second card which differs from the first one. The main advantages of the just described identity card are: • No secrete numbers or reference patterns are needed for identification, as in the case for the finger-print method. The risk of unqualified usurpation of these patterns or codes no longer exists. • Direct readability of the cards, if the PSPI and the numbers are visibly impressed. • Simple design and price-worthy production. • In appropriate instances, no need for troublesome electronics. • Secrete numbers or codes are not to be memorized. • A sufficiently large number of texts, the use of several columns of basic-numbers, the concealment or modification of the algorism, or the subdivision of the identification process into partial steps, will make the process as falsification-proof as wanted. Example 12: Authentification with authentcards. According to figure 10, each authentcard contains, assembled in groups, the names and first-names of sixteen people who are only within the remembrance of the card owner (for the sake of illustrating the principle, the names and first-names of contemporary personages are used which don't fulfil, of course, the fundamental psychometrical criterium of exclusive individual knowledge) . A prime number (basic-number BZ) is attributed to each name. The tying-together is as follows: ADENAUER-Konrad-BRECHT-Bertold-ERHARD-Ludwig etc. Altogether there are 15! « 1,31 x 10 12 different tying-together possibilities. The algorism is defined as: result-number EZ = ∑ Z χ 2 , where Z χ is defined as BZ χ • BZ χ+1 • BZ χ+2 . The result-number in this example is calculated to 6 927 236 929. The authentdevice (figure 11A) exhibits on its touch-screen the names and first-names as well as menu-indications. In order to exclude that an owner of an authentcard transfers without authorisation his/her card and his/her psychometrical knowledge to another person who might attempt to perform a forged authentification, it is opportune to accomplish in addition to the authentification according to the tying- together principle, a supplementary authentification on the basis of the characteristic-comparison principle. For instance, PSPI statements or biometrical characteristics of each participant in the system may be stocked in stationary information memories, with the help of which corresponding data produced during authentification, are being compared. Figure 11B shows how the authentdevice with touch-screen, already used for implementing the authentification according to the tying-together principle, can also be used for verifying PSPI statements, that is for authentification according to the characteristic-comparison principle. If biometrical characteristics are used for this supplementary authentification, very simple features like tallness, weight, head- eriphery etc. can be utilized, because it is only necessary to demonstrate that a person differs physically from another one, or does not. Example 13: Tele-authentification per telephone. According to figure 12A, the person to be authentified uses an authentdevice with touch-screen and authentcards (which are not shown) with 16 names, 16 first-names and 16 basic-numbers, for instance the first 16 prime numbers from 2 to 53. If no authentdevice is available, a simple card with the corresponding informations which is directly readable, and a pocket calculator with 12-digit display, will suffice. The use of a new-shaped authentdevice in the form of a small electronic calculator (figure 13) is, however, especially appropriate, as will be described in example 14. After introducing an authentcard, the picture represented in figure 12A will be exhibited on the touch-screen. The screen possesses in its lower part a display for exhibiting the result-number EZ = 6 927 236 929 which will be calculated after tying-together all names and first-names, and for exhibiting one of the basic-numbers attributed to the names, in the present case, BZ = 53. The authentdevice is equipped with means for generating numbers which can be used as a modified basic-number and will be exhibited on the left side of the lower part of the screen (in the example BZ = 59) . This new basic-number will be used instead of the original one (BZ = 53) . After touching the "okey"-field, the authentdevice calculates the new result- number EZ = 8 365 541 377. Initially, the four numbers remain visible. Next, the person to be authentified calls the authentifying instance, and communicates the original EZ = 6 927 236 929 and the original BZ = 53. The authentifying instance has acces to a data treatment device via a terminal. All persons participating in the authentification system have entered in it before the beginning of its operation and observing the necessary safety provisions, their result- number, chain of basic-numbers and possibly additional basic- numbers attributed to the names and first-names, as well as in appropriate instances individual algorisms. This data treatment device has a programme performing the following processes: After input of a correct result-number into the terminal, first the corresponding chain of basic-numbers will be approached; then a basic-number will be input in the terminal, so that - if that basis-number was correct - its corresponding basis-number in the chain is identified and activated. The programme then calculates according to an individual algorism or on the basis of an algorism common for all participants, from the approached chain of basic-numbers automatically the resuit-number, or replaces the identified basic-number by another one which was entered in the terminal. The display of the terminal of the authentifying instance is shown in figure 12B. It has a key-board (fields) for entering the ten basic digits, a cancellation button (field) "C" and a turning-on button (field) "on", as well as a domain for indicating the user-led menu. Finally a field for the exhibition of result- and basic-numbers, and a button (field) "okey". After turning-on the terminal, the user-led menu exhibits "Please enter the transmitted EZ, then push okey". The operator at the terminal then enters the original EZ = 6 927 236 929 and observes the result on the display, whereafter he/she operates the field "okey". By this, the chain of basic-numbers in the data treatment device of the person to be authentified, is approached and activated. Then follows the menu indication "Please enter the transmitted BZ, then push okey" . The operator complies with this indication by entering the BZ = 53 and operating the field "okey". This basic-number is identified and activated in the data treatment device, and the menu exhibits the request "Please request the new basic-number, then enter it, then push okey". The operator formulates the corresponding request on the telephone, receives of the person to be authentified the new BZ = 59, enters it into the terminal and confirms with the field "okey". Herafter, the data treatment device calculates the new result number EZ = 8 365 541 377 and exhibits it on the display. Then follows the menu indication: "Please request the new result-number and compare it with the one exhibited on the display, then push okey". The operator, after having transmitted the corresponding request by telephone, receives from the person to be authentified the new EZ = 8 365 541 377, compares it with the one on the display, and confirms in the case of positive result with the field "okey". The display hereafter exhibits "Authentification successfully accomplished" . If there was no conformity, the authentifying process is abandoned. The new chain of basic-numbers with the new BZ = 59 remains preserved within the authentdevice of the person to be authentified as well as within the data treatment device, furthermore the new EZ = 8 365 541 377 within the data treatment device, as an access criterium for the chain of basic-numbers. Time and progress of every authentification are recorded for the sake of surveillance. The data treatment device is programmed in such a way that each basic-number of the chain can only be modified once. If after a number of authentifications all original basic-numbers of a chain have been changed, the person to be authentified uses a complete new set of basic-numbers having the same tying-together order, conform with another one already available in the data treatment device, or to be generated in it at the necessary moment, and which will replace the preceding chain of basic-numbers after the ultimate modification of an original basic-number. The telephone authentifying method according to the invention is absolutely falsification-proof. The investment for communication is a minimum, because only two ten-digit and two two-digit numbers have to be transmitted in the example. Example 14: Pocket authentdevice. With regard to figure 13, a handy authentdevice composed of elementary components is described, by the use of which the person to be authentified can perform the main steps of telephone authentification speedily and flawlessly. This device is also suited for all kind of on-the-spot authentification and for preserving secrete codes (PINs) and other personal data. Signify in figure 13 : B a casing, A photocells, C a 12-digit display, D a switch for turning on and off the device and for initiating special functions, E a column of ten pushing buttons or release fields, F an area on which are inscribed ten names and first-names of persons who have been chosen by the owner of the device according to the criteria of psychometry. The ten buttons or fields are electronically covered each by a basic-number, as is shown in figure 13. As was already mentioned in example 12, additional basic-numbers which are not shown, may be attributed to the buttons or fields according to claims 8 and 10. Further features of the device result from claim 10. The authentifying process progresses as follows: 1. The owner turns on the device, whereafter the last calculated result-number appears on the display. Thus according to figure 13, EZ = 3 056 775 706, if the algorism was chosen as EZ = ∑ Z X/ with Zx = BZ X • BZ (x+ j • BZ (x+2 ) • 2. He/she operates one after another the ten buttons (fields) following the tying-together plan. The EZ = 3 056 775 706 appears once again on the display. This means self- authentification of the owner who may then continue by noting this result-number. 3. He/she pushes the button (field) beside 'name 6 and first- name 5' , until the basic-number BZ = 31 will appear on the display. He/she notes this basic-number. 4. He/she pushes again the same button (field), as long as a new basic-number will appear on the display, in the example BZ = 33. This new basic-number was generated by the owner with the means revealed by claim 10, or automatically by the authentdevice. He/she notes this new basic-number. 5. He/she repeats step 2, and gets the new result-number EZ = 2 891 394 442 on the display, which he/she notes. 6. He/she transmits the four numbers 3 056 775 706, 31, 23, and 2 891 394 442 by phone to the authentifying instance which then accomplishes the authentifying process with the means revealed in claim 9. The owner can exhibit possible preserved secrete codes (PINs) or other personal data on the display, after each successful self-authentification, through the pocket authentdevice and with the help of the supplementary functions mentioned in claim 10. The number of possible tele-authentifications is practically unlimited, because: first the quantity of basic- numbers needed for authentification is only limited by the memory volume of the authentdevice, and secondly the authentdevice can be loaded with fresh data from time to time, observing certain safety provisions.

The scheme for tying-together the texts is as follows: Start with an element Al of the first column, then go to element Bl of the second column which is logically correlated, then go to element CI of the third column which is correlated and so on; then go to element A2 of the first column which is placed in the same matrix-line as the element of the last column which has been tied-together, then go to element B2 etc. The tying-together process is terminated when the last element of the last column is tied-together. f) alphanumerical parts of secrete codes and supplementary letters or numbers, or integer numbers, or prime numbers, or series of numbers are utilized as attributed signs. g) attributed signs which are arranged in different columns or structures, are correlated to certain time periods or to certain authentification processes. h) the attributed signs are preserved in a authentdevice in such a manner that they become available only after a successful authentification. i) with the view of constructing authentification criteria for multinominal associations of the type Ax-Bx-Cx etc., the following operations are implemented: • the attributed basic-numbers are brought into a characteristic geometrical structure according to the tying-together scheme of the association elements, or they are transformed into characteristic result-numbers through calculations, so that each result-number is a function of all or a part of the basic-numbers and of their arrangement, or of the sequence of introducing the basic-numbers into the calculation. • every two, three or more basic-numbers which follow each other in the tying-together scheme are multiplied with each other, the calculated products are raised to a power, and the resulting elements of that series of numbers are added to form an integer result-number with a multitude of digits, j) the texts, basic-numbers, the result-number and possible parameters of calculation are preserved in individual authentcards which are readable by an authentdevice, or are preserved within a portable miniaturized authentdevice. k) the result-number is used as the individual number of the authentcard. 1) the authentdevice is equipped with a display, which exhibits the matrix built up from texts and basic-numbers after introducing the authentcard into the device or after putting the latter into operation, and by means of which the owner of the card can tie-together the texts, so that a programme installed in the authentdevice will automatically calculate the result-number from the basic-numbers, m) the basic-numbers, the result-number and other relevant data are automatically entered into an intermediary mechanical, electronic or magnetic short-time data carrier, from which they can be evaluated for renewed authentification within a determined time interval by a remotely located reading device, those data being cancelled after the reading process or after passing the interval. n) after a first authentification process, one of the basic-numbers is modified, and a new result-number is calculated. The original result-number and basic-number before modification, as well as the modified basic-number and the new result-number, are transmitted to a remote authentification instance, which has access to a data treatment device via a terminal. The data treatment device contains in electronically registered form and protected against unqualified extraction, for each participant in the system the tied-together chains of basic-numbers together with the original result-number and the calculation programme. After entering the original result-number and the original and the modified basic-number into the terminal, the corresponding registered original basic-number of the chain preserved in the data treatment device will be changed and a new result-number will be calculated and sent to the terminal display, or will be automatically compared with the transmitted new result-number. 9. An authentifying method according to claim 8, characterized by one or more of the following features: a) authentcards which contain: a multitude of associated names and first-names, basic-numbers which are attributed to them, an instruction for tying-together names and first- names, possible parameters of an algorism for calculating the result-number, and the result-number itself. b) stationary data treatment devices which contain a multitude of supplementary PSPI or biometrical features concerning the persons who participate in the authentification system. c) authentdevices with screen or touch-screen which display after introduction of an authentcard all or part of the first-names and consecutively one name at a time or simultaneously several or all names, and in addition the main parts of the supplementary PSPI which are transmitted from a stationary data treatment device, and other informations. d) means of action like keyboards and touch-screen pencils, with the help of which the displayed names and first-names can be tied-together and the displayed PSPI main parts can be verified or complemented. e) hardware and software for implementing the essential authentification functions like: displaying the names, first-names, PSPI main parts and other informations on the screen; implementation and evaluation of the tying-together of names and first-names; verification of statements; complementation of fragments of statements and comparison with the preserved statements; release of a result signal. f) in the case of a touch-screen: • after the display of each name, the person to be authentified touches the correlated first-name; • touching a wrong first-name is undoen by touching an undo- field; • each next name is displayed after touching a first- name, according to the inherent instruction for tying- together names and first-names; • after tying-together all names and first-names, the authentdevice calculates a result-number from the chain of basic-numbers formed according to the tying-together of names and first-names, by means of its inherent algorism, and signals successfull implementation of authentification, if the calculated result-number is conform with the result- number preserved in the authentcard. 10.An authentifying method according to claims 8 or 9 , characterized by the fact that the person to be authentified utilizes for the implementation of the main process steps an authentdevice which has all or part of the following features: a) a casing like a small flat electronic pocket calculator or an active authentcard having the format of a credit card; b) a display for the exhibition of numbers and/or letters; c) a photovoltaic or galvanic energy supply: d) a button or buttons for switching on the authentdevice and initiating supplementary functions; e) an area for the exhibition of words which are arranged in two columns, in a written or optically or electronically generated form; f) a transparent cover for the word area under which two- columns word boards are placed stationarily or interchangeably; g) push-buttons or function-release fields which are placed in a column matching with the word-columns, which are consecutively actuated by the person to be authentified according to the tying-together scheme of the words, and each of which releasing a predetermined basic-number for the calculations of the authentdevice or for exhibition on the display; h) inscription on the buttons or fields of the numbers 0 to 9 and/or of letters; i) an electronic function and calculation programme which implements the following processes: • to each button or field are attributed one or several basic-numbers, subsequent basic-numbers only being activated after once changing the first basic-number of all buttons or fields and in appropriate instances after re-calculation of the last calculated resuit-number, • after switching on the device, the last calculated result-number is presented in the display, • a new result-number is calculated from the released basic-numbers and presented in the display, • individual basic-numbers are shown in the display after extended or multiple actuation of the buttons or fields, or by other measures, • numbers are generated in the display by: actuating buttons or fields which carry numbers; scrolling a series of numbers in the display and stopping the scroll process when the desired number shows-up; random generation; or through other measures. These numbers are attributed to the buttons or fields as basic-numbers, or preserved in the device as a secret code (PIN) , • letters are generated in the display by actuating buttons or fields carrying letters, which can be attributed to the preserved codes or assembled to texts, • after successful authentification, the preserved PlNs or texts are exhibited in the display, • after invalid, unsuccessful or inadmissible authentification attempts, the authentdevice is prevented from further actuation, from further display of words, from further exhibition of basic- and result-numbers or numbers and letters, or from changing the basic-numbers attributed to the buttons or fields.
