     DETAILED DESCRIPTION 
       [0014]    An exemplary embodiment of the present invention will be described with reference to the accompanying drawings. An information processing device  1  according to a first aspect of an exemplary embodiment of the present invention includes, as shown in  FIG. 1 , a controller  11 , a memory  12 , an operating unit  13 , a functional unit  14 , a communication unit  15 , and a medium reader/writer  16 . 
         [0015]    The controller  11  may be a microprocessor, or the like, and operates according to a program stored in the memory  12 . The controller  11  instructs the medium reader/writer  16  every predetermined time (for example, regularly) to read information stored in the recording medium, and authenticates the user using the read information. 
         [0016]    When the user is authenticated, the controller  11  controls the functional unit  14  to carry out a process instructed via the operating unit  13 . A specific process to be carried out by the controller  11  will be described later in detail. 
         [0017]    The memory  12  includes a storage element, such as a RAM (Random Access Memory), a ROM (Read Only Memory), or the like. The memory  12  stores a program to be executed by the controller  11 . The program may be presented in the form of being stored in a computer readable recording medium, such as a CD-ROM, a DVD-ROM, or the like, and copied to the memory  12 . The memory  12  also operates as a work memory of the controller  11 . 
         [0018]    The operating unit  13  may be a numeric keypad, a touch panel, or the like, and receives an instruction operation by the user, and outputs the content of the operation to the controller  11 . 
         [0019]    The functional unit  14  realizes the function as the information processing device  1 . In the case where the information processing device  1  mentioned here is a multifunctional peripheral device, for example, which realizes in a composite manner the functions of a copier, a scanner, a printer, or the like, the functional unit  14  includes a flat bed scanner, a laser printer, and so forth. The information processing device  1  which is an information display device, or the like, may include a display, or the like. 
         [0020]    The communication unit  15  is connected to communication infrastructure, such as a network, a telephone network, or the like, and sends data to a designated destination via the communication infrastructure according to an instruction input from the controller  11 . The communication unit  15  also outputs the data received via the communication infrastructure to the controller  11 . 
         [0021]    The medium reader/writer  16  reads information from a card-like recoding medium which possesses a radio communication function, such as, for example, an RFID (Radio Frequency Identification), or the like, according to an instruction input from the controller  11 , and outputs to the controller  11 . 
         [0022]    Further, according to the instruction input from the controller  11 , the medium reader/writer  16  records the instructed information into a card-like recording medium which possesses a radio communication function. 
         [0023]    In the recording medium from which information is read using the medium reader/writer  16  of the information processing device  1  of this exemplary embodiment, as shown as an example in  FIG. 2 , information for identifying a recording medium (unique information, or the like; a1) and information about a expiration date (a2) are stored as information (A) relevant to authentication. The recording medium additionally stores, as information (B) about a contact destination, the mail address of a portable phone of a user identified by the authentication-related information. 
         [0024]    Here, operation of the controller  11  in the exemplary embodiment will be described. In this exemplary embodiment, a program to be executed by the controller  11  includes, in terms of function, an authentication unit  21 , a functional processing unit  22 , a left-behind detection unit  23 , and a report unit  24 , as shown in  FIG. 3 . 
         [0025]    Upon receipt of a request for authentication from the functional processing unit  22 , or the like, for example, the authentication unit  21  instructs the medium reader/writer  16  to read information from a recording medium placed close thereto. Then, upon input of the information read by the medium reader/writer  16 , the authentication unit  21  carries out authentication based on the input information. In the above, the authentication may be carried out, for example, through verification using unique information stored in advance in the memory  12  or using a widely known authentication technique, such as PKI (Public Key Infrastructure), or the like, with detailed description thereof not included here. 
         [0026]    When the authentication-related information read by the medium reader/writer  16  contains information about a expiration date, the authentication unit  21  compares the expiration date information and the present time and date (time and date when the authentication is carried out), measured by a time measurement device (not shown) for measuring the present time and date, and when the expiration date is already passed, determines that authentication fails. 
         [0027]    Meanwhile, with successfully completed authentication, the authentication unit  21  outputs information indicative of that fact to the unit having requested the authentication. When the authentication fails or no information is read from the card (when no card is placed close to the medium reader/writer  16 , or the like), the authentication unit  21  outputs information indicative of an error to the unit having requested the authentication. 
         [0028]    The functional processing unit  22 , having received the content of the instruction operation carried out by the user using the operating unit  13 , requests the authentication unit  21  to authenticate the user. Then, upon receipt of the information from the authentication unit  21 , informing of successfully completed authentication, the functional processing unit  22  carries out a process, including control of the functional unit  14 , or the like, according to the received instruction operation. For example, the functional processing unit  22  of the processing device  1  which is a multifunctional peripheral device may operate as described in the following example. 
         [0029]    That is, suppose here that the user operates the operating unit  13  to instruct copying with their recording medium placed in contact with the medium reader/writer  16 . Then, the controller  11  controls such that the functional processing unit  22  requests the authentication unit  21  to make authentication. Accordingly, the authentication unit  21  carries out authentication based on the information read by the medium reader/writer  16 . With successful authentication and information output informing to that effect, the functional processing unit  22  controls the functional unit  14  according to the user instruction to output the image data read by the scanner to the printer to copy. 
         [0030]    Upon completion of the process by the functional unit  14 , the functional processing unit  22  outputs a signal indicating a completed process to the left-behind detection unit  23 . 
         [0031]    The left-behind detection unit  23  requests the authentication unit  21  every predetermined time (for example, regularly) to carry out authentication. When the information indicating successful authentication is kept received over a predetermined period, the left-behind detection unit  23  obtains contact information in the information read by the medium reader/writer  16 , and outputs the obtained contact information to the report unit  24 . 
         [0032]    Here, the above-mentioned predetermined period may be the entire period during which the same authentication information is still being read (that is, a period of time with a certain recording medium remaining in contact with the medium reader/writer  16 ) or a period of time between receipt of a signal indicating a completed process, sent from the functional processing unit  22 , and elapse of a predetermined period of time after the receipt. Here, suppose that the predetermined period is defined as a period of time between receipt of a signal indicative of a completed process, input from the functional processing unit  22 , and elapse of a predetermined period of time after the receipt. In this case, the recording medium is determined as having been left behind when the recording medium is kept in contact with the medium reader/writer  16  for a predetermined period of time after the process designated by the user is completed. In other words, the recording medium is not determined as having been left behind while the process relative to the recording medium is still being carried out. 
         [0033]    The report unit  24 , having received the contact information, controls the communication unit  15  to send predetermined information by means of an electronic mail, or the like, to the input contact information. The predetermined information to be sent to the contact destination may include information relevant to authentication. In this case, information relevant to authentication (information for identifying a recording medium or a valid period) may be newly issued. For example, information for identifying a recording medium may be newly issued for replacement. The information being replaced may be invalidated (information which cannot be authenticated). 
         [0034]    As a specific example of the process, suppose that authentication is granted based on whether or not the unique information read from the recording medium coincides with the information stored in advance as verification information. In this case, the unique information to be invalidated is deleted from the verification information, and the newly issued unique information is included in the verification information. 
         [0035]    Also, in the case where authentication is granted while inquiring of an authentication server (not shown), the unique information to be invalidated is notified to the authentication server to inhibit authentication for the recording medium which stores the unique information. Thereafter, a request is made for registration of the newly issued unique information in the authentication server to enable authentication for the recording medium which records the newly issued unique information. 
         [0036]    In this exemplary embodiment, a user having left an IC card, or a recording medium for authentication, in a medium reader/writer connected to a multifunctional peripheral device, or the like, which serves as the information processing device  1  receives an electronic mail, or the like, informing that an IC card has been left behind, which is sent to the destination recorded in the IC card. 
         [0037]    When the electronic mail, or the notice, includes authentication-related information, it is possible to arrange a different IC card to be usable as a recording medium for authentication by recording the authentication-related information into the IC card. 
         [0038]    Recently, a portable phone, a PDA (Personal Digital Assistant), and so forth, possessing a function of RFID (Radio Frequency Identification), have become available. When the above-described notice is received by such a portable phone, PDA, or the like, it is possible to arrange the portable phone or the PDA itself to be usable as a recording medium for authentication by recording the authentication-related information, contained in the notice, into the portable phone, the PDA, or the like. In this case, should software for recording or deleting, or the like, the authentication-related information in the portable phone, the PDA, or the like be necessary, the software may be additionally sent, contained in the above-described predetermined information. 
         [0039]    When authentication information is held in a portable phone, or the like, as described above, the information processing device  1  may copy the authentication information to a different recording medium (an IC card, or the like). For example, the controller  11  having received a user instruction for copying instructs the user to place the medium (a portable phone, or the like, here) which holds the authentication information to copy in contact with the medium reader/writer  16 . Then, when the user places the portable phone, or the like, which holds the authentication information to be copied, close to the medium reader/writer  16 , the medium reader/writer  16  reads the authentication information, and outputs to the controller  11 . The controller  11  thereby holds the authentication information, then obtains present time and date information (time and date when the process is carried out) from the time measurement unit (not shown), and determines whether or not the present time and date is before the expiration date with reference to the expiration date information of the authentication information held. When it is determined that it is before the expiration date, the controller  11  instructs the user to place a recording medium into which the information is to be copied in contact with the medium reader/writer  16 . When the user, in response to the instruction, places the recording medium to which the information is to be copied close to the medium reader/writer  16 , the controller  11  then instructs the medium reader/writer  16  to write the authentication information into the recording medium. 
         [0040]    It should be noted here that, whereas the information processing device  1  itself carries out authentication and notification in the above, in the case where a management center manages the authentication information, the information processing device  1  may report leaving-behind to the management center. 
         [0041]    That is, an information processing system according to another (second) aspect of an exemplary embodiment of the present invention includes, as shown in  FIG. 4 , at least one information processing device  1 , a medium management center-side device  2 , and a user side terminal  3 , all connected to one another via a communication infrastructure, such as a network, or the like, so as to communicate with one another. 
         [0042]    The information processing device  1  in the second aspect of the embodiment has a similar structure to that of the device above described, but the content of the processing by the controller  11  is slightly different, as will be described later. 
         [0043]    The medium management center side device  2  is realized using a computer, such as a server device, or the like, and upon receipt of a notice about a recording medium left behind sent from the information processing device  1 , obtains information about a contact destination designated in association with the recording medium. Then, the medium management center side device  2  sends predetermined information to the contact address. An example of operation of the medium management center-side device  2  will be described later in detail. 
         [0044]    The user side terminal  3 , which is a device for receiving a notice, such as an electronic mail, or the like, from the medium management center-side device  2 , may be a portable device, such as a portable phone, a PDA, or the like, or a personal computer, or the like. 
         [0045]    The controller  11  of the information processing device  1  in this aspect of the embodiment includes, in terms of function, the authentication unit  21 , the functional processing unit  22 , the left-behind detection unit  23 , and a report unit  25 , as shown in  FIG. 5 . Units for operations similar to above described are assigned identical reference numerals, with details thereof not described here. 
         [0046]    In the second aspect of the embodiment, the report unit  25  operates differently from above described. That is, upon receipt of the contact information, the report unit  25  in this aspect of the embodiment controls the communication unit  15  so as to send the input contact information and the authentication-related information to the predetermined medium management center-side device  2 . 
         [0047]    In this aspect of the embodiment, the authentication unit  21  may send at least a part of the authentication-related information read by the medium reader/writer  16 , for example, the unique information of the recording medium, to the medium management center-side device  2  so that the medium management center-side device  2  carries out authentication. 
         [0048]    The medium management center side device  2  stores, as shown in  FIG. 6 , a user identifier (Q) unique to each user, unique information (R) of a recording medium, and a re-issuance frequency (S) in the manner of all being associated with one another. Then, when the medium management center side device  2  receives the unique information of the recording medium together with the authentication request from the information processing device  1 , the medium management center side device  2  compares the received unique information and the unique information stored therein to carry out an authentication process. 
         [0049]    The medium management center-side device  2  receives contact information and authentication-related information from the information processing device  1  having found the recording medium left behind. The medium management center-side device  2  then notifies the received contact destination of the recording medium left behind. It is assumed here that the user receives the notice at the user side terminal  3 . 
         [0050]    The medium management center-side device  2  may include contact information for use in generating a re-issuance request for a recording medium in the notice to be sent to the user side terminal  3 . For example, in the structure in which the medium management center-side device  2  operates as a web server, presenting a web page for receiving a re-issuance request of a recording medium, the notice may include the URL (Uniform Resource Locator) of the web page. In this case, if the user terminal device  3  possesses a web access function, requesting the web page by designating the URL ensures a situation in which a re-issuance request of a recording medium can be made. That is, the medium management center-side device  2  receives a re-issuance request of a recording medium from the user based on the notified information. 
         [0051]    Upon receipt of the re-issuance request, the medium management center side device  2  increments by one the re-issuance frequency, stored in association with the information for specifying the user having made the request, then invalidates the unique information of the recording medium, stored in association with the information for specifying the user having made the request, and overwrites the invalidated unique information, using the newly issued unique information, for example. It should be noted that the information for specifying a user having made the request may be encouraged to be input on the web page for receiving the above-described re-issuance request. Alternatively, the information for specifying a user (for example, unique identification information for every notice) may be contained in the URL to be sent to the user side terminal  3  so that the specifying information is held in association with the unique information to be re-issued, or the like. In the latter case, reference to the unique information to be re-issued, stored in association with the information contained in the received URL, enables specification of the user. 
         [0052]    In the case of the user side terminal  3  which is a portable phone, a PDA, or the like, possessing a function as an RFID, the medium management center-side device  2  may newly issue authentication-related information in response to a request from the user side terminal  3 , and send the issued information to the user side terminal  3  having made the request. In this case, a shorter period of validity may be set compared to the case in which the expiration date is recorded in a recording medium. Should the portable phone, the PDA, or the like, serving as the user side terminal  3 , need software for recording, deleting, or the like, the authentication-related information, the medium management center-side device  2  may additionally send the software. 
         [0053]    The medium management center-side device  2  may apply a predetermined process, including transmission of alert information, or the like, to a user having the re-issuance frequencies in excess of a predetermined threshold.

It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obviously, many modifications and variations will be apparent to practitioners skilled in the art.
