A system for providing global biometric identification services to a plurality of remote parties, the system comprising: a template receiver, which comprises: a registration input configured to receive from at least one remote registering party at least one registration template of a biometric sample of an end user of the remote registering party, associated with a tag relating the template to the end user, and an enquiry input, configured to receive from a remote inquiring party at least one test template of a biometric sample of a person. The system also comprises a verifier, associated with the inputs, configured to determine a degree of match between the registration template and the test template, thereby to verify the person as an end user, using the determined degree of match.
The present invention relates to biometrics and, more particularly, but not exclusively to a system and method for providing a biometric identification service.
Biometric identification refers to the automatic identification of a person based on his/her physiological or behavioral characteristics. This method of identification is preferred over more traditional methods involving passwords and PIN numbers for various reasons: (i) the person to be identified is required to be physically present at the point-of-identification; (ii) identification based on biometric techniques obviates the need to remember a password or carry a token.
Specifically, with increased use of computers as vehicles of information technology, it is necessary to restrict access to sensitive/personal data. By replacing PINs, biometric techniques can potentially prevent unauthorized access to or fraudulent use of ATMs, cellular phones, smart cards, desktop PCs, workstations, and computer networks. PINs and passwords may be forgotten, and token based methods of identification like passports and driver's licenses may be forged, stolen, or lost.
Thus biometric based systems of identification are receiving considerable interest. Various types of biometric systems are being used for real-time identification, the most popular are based on face, iris and fingerprint matching. However, there are other biometric systems that utilize retinal scan, speech, signatures and hand geometry.
Biometric identification and authentication systems were introduced into a variety of processes implemented by organizations such as financial institutions, medical institutions, government organizations, etc.
For example, U.S. Pat. No. 7,047,419 to Black et al, filed on Oct. 28, 2001, entitled: “Data Security System”, describes a data security system which comprises a host processor, and a plurality of remote computers. Each remote computer provides biometric authentication of a user prior to responding to the user request for data access. The remote computers are handheld when in operational mode. A sensor in the handheld computer captures a biometric image while the remote computer is being used. The biometric sensor is positioned in such a way that the sensor enables the capture of the biometric image continually during computer usage with each request for access to secure data. The biometric authentication occurs in a seamless manner and is incidental to the data request enabling user identity authentication with each request to access secure data.
U.S. Pat. No. 7,043,754 to Amouse et al, filed on Jun. 12, 2003, entitled “Method of secure personal identification, information processing, and precise point of contact location and timing”, describes a lightweight and easily carried memory identification card. The memory card includes a file system of electronic files on the card, which are automatically detected and recognized by selected authorized readers. The file system is organized so that stored electronic files appear in separate and distinct encrypted compartments in the card, so that only authorized preselected readers have access to particular compartments. Biometric identifying information is imprinted in the card, so that no data can be transferred unless there is a biometric match between a reader and a person assigned to the card and who possesses the card. The separate compartments of the memory card may include a compartment containing medical, administrative or financial information relating to the assigned user of the card, wherein the information is accessed only by a preselected memory card reader having the unique pin code assigned to the compartment having the medical information. The memory identification card can also have a single chip Global Positioning System (GPS) to identify where the card is being used.
U.S. Pat. No. 7,003,670 to Heaven et al, filed on Jun. 8, 2001, entitled “Biometric Rights Management System”, describes an apparatus and method for using biometric information to control access to digital media that is obtained over a network such as the Internet. Encryption, techniques are used in combination with biometric verification technology to control and monitor access to online or locally held media. Biometrics such as keystroke dynamics are measured at a user's computer to confirm the identity of a user for the purpose of allowing the user to audit music files to which the user has authorized access.
U.S. Pat. No. 6,985,887 to Sunstein et al, filed on Nov. 24, 1999, entitled “Apparatus and method for authenticated multi-user personal information database”, describes a method of assuring integrity of personal information in a data base. The database contains personal information provided by multiple users. In various embodiments, physiological identifiers associated with each of the users are stored in the database. Related systems are also described by Sunstein et al.
U.S. Pat. No. 6,928,547 to Brown et al, filed on Jul. 7, 2003, entitled “System and method for authenticating users in a computer network”, introduces a rule based biometric user authentication method and system in a computer network environment. Multiple authentication rules can exist in the computer network. For example, there may be a default system-wide rule, and a rule associated with a particular user trying to log in. There may be other rules such as a rule associated with a remote computer from which the user is logging in, a rule associated with a group to which the user belongs, or a rule associated with a system resource to which the user requires access such as an application program or a database of confidential information. An order of precedence among the rules is then established which is used to authenticate the user.
U.S. Pat. No. 6,928,546 to Nanavati et al, filed on May 14, 1999, entitled “Identity verification method using a central biometric authority”, describes a method for performing biometric verifications, to authenticate the identification of users using a central biometric authority (CBA). This allows parties to an electronic transaction to be assured of each other's identity. Specifically, at the sender side, a first message to a receiver is generated, wherein the first message includes a message text and a unique message identifier (UMI).
At the sender side, a second message concerning a posting to the CBA is also generated, wherein the second message includes the sender's biometric sample, the UMI, and the sender's submission profile record. At a receiver side, it is decided that if a receiver wishes to verify the sender's identity and if so, the first message is automatically verified. At the receiver side, a third message concerning a receiver's posting to the CBA is issued, the third message including only the UMI, as received from the sender side. Finally, at the CBA, a reply to the third message is provided, the reply including the sender's verification result.
Implementations of current biometric identification solutions, such as the ones described hereinabove, are specific with regards to the biometric equipment used.
Furthermore, with the current solutions, an organization may have to develop, buy, or install a complete biometric system including: biometric readers, computer drivers to control the biometric readers, software for generating biometric signatures (templates) from the read biometric values (say the from the image of a fingerprint read by a biometric reader), software for processing the biometric data read and comparing the processed biometric data with existing biometric data (say for authentication or identification of end users), dedicated databases to store the biometric data, etc.
A complete biometric system may be too expensive to buy and maintain, specifically for a relatively small business, which may not have experienced IT workers, and cannot finance the development of a complete biometric system which suits the needs of the business.
For example, a small drugstore chain is not likely to have the resources to develop a complete end-to-end system for biometric identification, say for controlling the distribution of prescription narcotic pain relievers by the chain's staff.
There is thus a widely recognized need for, and it would be highly advantageous to have, a system devoid of the above limitations.
According to one aspect of the present invention there is provided a system for providing global biometric identification services to a plurality of remote parties, the system comprising: a template receiver, comprising: a) a registration input configured to receive from at least one remote registering party at least one respective registration template of a biometric sample of an end user of the remote registering party, associated with a tag relating the template to the end user; and b) an enquiry input, configured to receive from a remote inquiring party at least one test template of a biometric sample of a person; and a verifier, associated with the template receiver, configured to determine a degree of match between the registration template and the test template thereby to verify the person as an end user, using the determined degree of match.

The present embodiments comprise a system and method, for providing biometric verification services to a plurality of remote parties. Preferably, the services are provided to the remote parties through the Internet.
Preferred embodiments of the present invention aim at providing a system, which supports a global biometric identification service for remote parties, which subscribed to the global biometric identification service. Typically, the remote parties are organizations which lack a full end-to-end biometric identification system, implemented as a part of their computer network, intranet, web site, etc.
A remote party registered to the global biometric service, provides the operators of the apparatus biometric samples of end users of the remote party, and a user number, associated with each sample. The biometric sample may be an image of a fingerprint, a face image, or any sample of a biometric characteristic of a person, as known in the art. The user number may be assigned by the remote party to the sample. The user number serves to identify the sample as belonging to a certain end user of the remote party (or a certain group of end users). Optionally, the user number is selected from numbers allocated to the remote party by the system's operator, in advance.
For example, a drugstore may send the operators of the system a biometric sample (say a fingerprint image) of each member of the chain's staff. The small drugstore further sends an employee number, associated with biometric sample, without giving in any other detail identifying the employee (such as the name of the employee, or the national insurance number of the employee).
When the employee wishes to dispense a prescription narcotic pain reliever to a client, the employee has to put his finger in a finger reader. Preferably, the employee also has to enter a user number such as en employee number. The image of the finger is sent, via the internet, to the system (Optionally, with his employee number). The system processes the fingerprint image and identifies the fingerprint as belonging to employee number as previously received. The system sends the employee number to the computer system of the drugstore, thus providing a verification of the identity of the employee. The computer system of the drugstore identifies the employee as a pharmacist, using the employee number. Finally, the employee is allowed to dispense the narcotic drug to the client.
Reference is now made to FIG. 1, which is block diagram illustrating a system for providing global biometric identification services to a plurality of remote parties, according to a preferred embodiment of the present invention.
The services may include:
authentication services—where there is established the validity of an end user attempting to gain access to a system,
verification services—where there is established the validity of a claimed identity, and
identification services—where the user is identified as a certain end user, previously registered with the system.
System 1000 for providing global biometric identification services to a plurality of remote parties includes a template receiver 110.
The remote parties may be, but are not limited to small businesses, organizations, etc, which lack a full end-to-end biometric identification system of their own, implemented as a part of their computer network, web site, etc.
The template receiver 110 includes a registration input and an inquiring input.
The template receiver 110 receives one or more registration templates of biometric samples, from a remote registering party 101, via the registration input. Each registration template belongs to an end user 111 of the remote registering party 101. The remote registering party 101 is one of the above parties, who subscribes to the global biometric identification services.
For example, the templates may be received through an offline interface (in a batch mode, say using a file containing a list of templates and a tag associated with each of the templates), an online interface (say, using a web site, or a client application installed at premises of the remote party), or through both the offline interface and the online interface.
A template of a biometric sample is a binary record created from distinctive information from a biometric sample such as a fingerprint image, a face image, an iris image, etc.
Preferably, the template is a condensed form of the biometric sample. That is to say, the condensed form comprises the results from some kind of analysis and summary of the biometric sample. For example, the template may be generated using an algorithm, which analyzes locations of minutia contained in fingerprints or a mathematical summary of the patterns in an iris image, as described in further detail hereinbelow.
Optionally, the template is a non-condensed binary representation of the biometric sample, such as a bitmap image of a fingerprint, or the image of a face. However, a non-condensed template may create unnecessary data transmission and processing overload on a system.
The templates may be of any type of a biometric sample, or a combination of types. For example, one biometric sample may be a fingerprint image, a second sample may be a face image, a third may me an image of an iris, etc.
The registering party 101 is a remote party, who wishes to register templates of biometric samples of his end users 111 (say his workers, customers, etc). The templates of the end users 111 are registered, so as to allow the identification, authentication or verification of the end user 111, as described in further detail hereinbelow. Through registering the end users 111, the end users 111 are enrolled in the system 1000.
For example, a registering party 101 may be a small business, such as a Golf Club. The club may register templates of face images of members 111 of the club's closed circle of clients with the system 1000. The club sends the system 1000 a registration template extracted from a face image associated with each of the client numbers 111. The registration templates are used for identification of a client immediate as the client arrives at the club, as described in further detail hereinbelow.
Thus, each of the templates sent by the registering party 101 is received with a respective tag, such as a user number. The tag identifies the template as belonging to an end user 111 of the registering party 101.
The template receiver 110 may also receive one or more test template(s) of (a) biometric sample(s) of a person 121 to be verified or identified as an end user of an inquiring party 102 who sends the template(s) of the sample(s) of the person 121.
The templates may be of any type of a biometric sample, or a combination of types. For example, one biometric sample may be a fingerprint image, a second sample may be a face image, a third may be an image of an iris, etc.
Optionally, the template of the person's biometric sample is received together with a claimed tag (say a user number) to be verified as belonging to the person 121.
An inquiring party 102 is one of the remote subscribing parties, subscribed to the services of the system 1000, who have biometric samples of their end users, stored in the storage 150, as described in further detail hereinabove. Optionally the Registration party and Inquiring party may be the same.
Preferably, the system 1000 further includes a template extractor 120, installed at premises of remote parties.
The template extractor 120 extracts a template from a biometric sample, taken from the end user 111, or a person 121 to be verified as an end user 111, as described in further detail hereinbelow. The templates are than sent to the system 1000, by the remote party.
Preferably, the template extractor 120 automatically identifies the type of a biometric characteristic sampled in the biometric sample. For example, the automatic identification may be carried out using an analysis of the general shape of the object in an image, be it a round shape of a human iris, a fingerprint which has a typical fingerprint shape, a face image consisting of eyes, nose, etc.
Then, the template extractor 120 may implement a template extraction algorithm which best fits the identified type of biometric characteristics sampled, as described in further detail hereinbelow.
Preferably, apparatus 1000 further includes a storage 150 connected to the template receiver 110. The storage 150 stores the template associated with the tag, for the registering party 101.
The apparatus 1000 further includes a verifier 140, connected to the template receiver, and the storage 150.
If the template is received from the inquiring party 102 without a claimed tag (say a user number), the verifier 140 determines a degree of match between the template of the biometric sample of the person and any of the templates stored for the inquiring party in the storage 150.
If the template is received from the inquiring party 102 with a claimed tag, the verifier 140 determines a degree of match between the template of the biometric sample of the person and any of the templates associated with the claimed tag. That is to say, the verifier 140 attempts to match the test template received from the inquiring party with templates associated with the tag.
The verifier 140 further verifies if the person is an end user of the inquiring party, based on the determined degree of match. Preferably, the verifier 140 may use a predefined policy for the verification.
For example, the predefined policy may include different minimal degrees of match, defined for each different end user, each different remote party, etc. Optionally, the template receiver 110 further receives the minimal degree of match from a remote party.
Optionally, the minimal degree of match is received from the inquiring party 102, associated with the specific test templates sent for the person 121, and used for the specific test templates only.
For example, if a bank wishes to verify the identity of an end user at an ATM (Automatic Teller Machine), the bank may send the system 1000 a low minimal degree of match when the ATM is in the end user's home town. However, the bank may send the system 1000 a higher minimal degree of match when the ATM is a town remote from the end user's home town.
Optionally, there may also be predefined a policy, for sampling of different types of biometric characteristics of the person. For example a policy may define sampling a fingerprint only in one case, and both a fingerprint and face image in another case. Optionally, the policy may be implemented through a multi-step process, as described in further detail hereinabove.
Preferably, the remote parties communicate with the sample receiver 110 and the verifier 140, via the-internet network 115.
Preferably, the verifier 140 also determines a degree of match between the test template of the biometric sample of the person 121 and any of the registration templates received from a registering party who has a predefined sharing agreement with the inquiring party 102. The verifier may identify or verify the person 121 as an end user of the party who has a sharing agreement with the inquiring party 102.
For examples, two nightclubs may have a sharing agreement. Consequently, each person, whose fingerprint's template is registered in the storage 150 for one of the clubs (say for implementing a blacklist of vandalistic clubbers), may also be identified, by sampling the fingerprint of the person, when the person arrives at the other club, as described in further detail hereinbelow.
Preferably, system 1000 further includes a time manager, connected to the verifier 140.
The time manager records time of reception of the test template of the biometric sample of the person. The time event is recorded for the tag (say a user number) associated with the template matched by the test template, by the verifier 140, as described in further detail hereinabove.
Optionally, the time manager sends data pertaining to the time events to a remote party, in a predefined format. The remote party may use the data for a time and attendance system, or forward the data to a third party providing a time and event system, as described in further detail hereinbelow.
Preferably, system 1000 further includes a duplicate templates locator, for locating duplicate templates in the storage 150.
The duplicate templates locator may also remove a duplicate template, and maintain a cross index, for referencing the remaining unique template using two or more tags of two or more remote parties.
Preferably, system 1000 further includes a quality monitor 190, connected with the template receiver 110 and the verifier 140, and deployed on a computer server not used to implement the template receiver 110 or the verifier 140.
The quality monitor 190 monitors the quality of service provided by the system 1000 through a predefined monitoring scheme. The monitoring scheme includes a sequence of operations, to be performed on the template receiver 110 and the verifier 140, and a desired response associated with each of the operations.
The quality monitor 190 samples the service, by automatically carrying out the predefined operations according to predefined monitoring scheme, comparing the desired result associated with the operation, and recording the operation and results in a log.
Preferably, the quality monitor 190 further sends a message (say an e-mail message, an SMS message, or any other messaging method known in the art) to predefine receiver, such as a system administrator, upon receiving and undesired result, according to a predefined scheme.
The quality monitor 190 may use a predefined scheme for sending the messages. The scheme defines when the message is to be sent, to whom, etc.
Preferably, system 1000 also includes a process manager, connected to the template receiver 110.
The process manager may be used to manage a predefined multi-step biometric identification process, where the remote party is prompted to provide a new test biometric sample in each stage, as described in further detail hereinbelow. Optionally, the remote party may also be prompted to provide a password from the biometrically sampled person, in one of the steps.
According to a preferred embodiment of the present invention, a system for providing global biometric identification services to a plurality of remote parties may also include a web site.
The web site provides a web based interface to a sample receiver 210, a template receiver 110, a verifier 140, etc.
The web site may be used to receive samples or templates from remote parties and register end users, for providing the results of biometric identification processes to a remote party, for providing operational and statistical reports to the parties (using a report generator, as known in the art), etc.
Reference is now made to FIG. 2, which is a block diagram illustrating a second system for providing global biometric identification services to a plurality of remote parties, according to a preferred embodiment of the present invention.
System 2000 for providing global biometric identification services to a plurality of remote parties includes a sample receiver 210. The sample receiver 210 includes a registration input and an inquiring input.
The remote parties may be, but are not limited to small businesses, organizations, etc, which lack a full end-to-end biometric identification system of their own, as described in further detail hereinabove.
The sample receiver 210 receives from a remote registering party 201 (one of the above parties), which is subscribed to the global biometric identification services, one or more registration biometric samples of a respective end user 211 of the remote registering party 201. The sample receiver 210 receives the registration samples, using the registration input.
The registration samples may be received through an offline interface, an online interface (say, using a web site or a client application installed at premises of the remote party), or through both the offline interface and on line.

Reference is now made to FIG. 9, which illustrates template extraction from fingerprint images, according to a preferred embodiment of the present invention.
The template extractors described hereinabove may use any of known in art algorithms for generating templates from a biometric sample. The biometric sample may be a fingerprint image, an iris image, etc.
For example, a fingerprint is made of a series of ridges and furrows on the surface of the finger. The uniqueness of a fingerprint may be determined by the pattern of ridges and furrows as well as the minutiae points 91, as illustrated in FIG. 9-a. Minutiae points 91 are local ridge characteristics that occur at either a ridge bifurcation or a ridge ending.
Algorithms for generating templates from a fingerprint may be placed into two categories: minutiae-based and correlation based.
Minutiae-based algorithms first find minutiae points and then map their relative placement on the finger, with respect to position and direction, as illustrated in FIG. 9-b. For example, some algorithms count the number of ridges between particular points, generally the minutiae, as illustrated in FIG. 9-c. The numbers are than stored in a template.
Correlation based algorithms use the general shape of the ridges. The fingerprint is divided in small sectors 94. The ridge direction, phase and pitch in each sector is extracted 95, and the binary representation of each sector is stored in a predefined position in a template, as illustrated using FIG. 9-d.
The exemplary systems and methods, described hereinabove, may have a variety of applications.
For example, dance bars in one country may share a blacklist of trouble making visitors, utilizing sharing agreements, as described in further detail hereinabove.
A night club manager may be able to constantly monitor the numbers of female and male clubbers inside the club, and balance the numbers (allowing entrance only to girls when there are more boys inside, and vise versa).
In another example, the biometric services described hereinabove may also be used in elections, to monitor the voting.
In yet another example, the biometric services provide by systems and methods described hereinabove, may be used for preventing profiteering by selling Football tickets in the black market.
Reference is now made to FIG. 10, which is a flowchart illustrating a method for selling a ticket and biometrically sampling a buyer, according to a preferred embodiment of the present invention.
An original buyer of a ticket is biometrically scanned 1010, say by taking the fingerprint of the buyer. The sample is sent 1020 to the system, which extracts 1030 a template from the sample. The template is stored 1040 associated with a unique ticket number, as described in further detail hereinabove.
Reference is now made to FIG. 11, which is a block diagram illustrating a method for verifying the identity of a ticket owner, according to a preferred embodiment of the present invention.
Upon arrival of a ticket owner in the stadium, a biometric sample (say, a fingerprint) is taken 1110 from the owner. The sample is sent 1120 to the system, together with the ticket number. The system extracts 1130 a template for sample. The system verifies 1140 if the owner of the ticket is the original buyer of the ticket. The verification is carried out by determining a degree of match between the template extracted 1130 from the owner's biometric sample, and the template stored associated with the ticket number, as described in further detail hereinabove.
If the owner is verified 1150 as the original buyer of the ticker, the gates are opened 1160 for the owner who enters the stadium. Otherwise, the owner may be allowed to try again 1170, say for a predetermined number of times, until a final rejection is issued 1190, upon which the ticket is marked as invalid.
In a similar example, movie tickets may be bought through a web page, and a fingerprint may be taken from each buyer and be associated with the ticket number. The fingerprint and the ticker number are sent to the system, and stored, as described in further detail hereinabove. When the buyer arrives at the cinema theater, the buyer is fingerprinted. If the template of the fingerprint taken from the buyer matches the template of the fingerprint associated with the ticket, the ticket is printed, and the buyer may enjoy the movie.
Other applications may involve registering tourists in hotels, with biometric samples, and providing the tourists services such as dinners and attractions by identifying the tourists, using the samples, providing biometric identification services to web sites, etc.
