  However, the above conventional technique has the following problems. The authentication information (fingerprint, user ID, password, etc.) is attached to the print data and sent to the authentication server or printer so that the authentication information can be transferred to the outside when a device such as the authentication server is taken away. There is a possibility of leakage, which raises a security problem.

  In addition, an authentication server and a printer require a large amount of memory and an information storage medium such as an HDD (Hard Disk Drive), which increases the product cost and is difficult to realize in an embedded device that requires a lower price.

  Accordingly, the present invention has been made in view of the above problems, and provides a printing security system in which a printer system compatible with high security can be introduced at a low cost.

A first invention is an authentication server including an individual recognition device that responds to a print request from a communication terminal device via a network, and manages a print request receiving unit that receives the print request, and the print request The print request management unit, the individual information input unit by which the user inputs the individual information using the individual recognition device, the individual information of the user registered in advance, and the print data linked with the individual information Individual information inquiry means for requesting verification of the individual information input by the individual recognition device for all of the communication terminal devices, and a verification result of individual information matching from the communication terminal device , Print permission means for transmitting print permission to the communication terminal device having print data linked to individual information, and receiving the print data in response to the print permission. Print output means for transferring to a printing apparatus registered in the authentication server, and print result notifying means for notifying the communication terminal device of normal termination of print data when transfer of the print data is completed. It relates to a featured authentication server.

  That is, according to the first invention, in the authentication server, when the print request accepting unit accepts the print request from the communication terminal device, the print request managing unit registers the received print request information in the authentication server. The individual information input means obtains input data as individual information such as fingerprints and veins by the user in the individual recognition device provided in the authentication server, and the individual information inquiry means is already registered in the authentication server as print request information. Inquiries are made to all the communication terminal devices, whether the individual information entered by the user is from the communication terminal device that sent the print request, and the print permission means For the communication terminal device having the print data linked with the individual information that matches the individual information transmitted by the individual information transmitting means upon receiving the individual information collation result The print permission is transmitted, the print output means receives the print data from the communication terminal device temporarily suspended in response to the print permission, transfers the print data to the printing device, and the print result notifying means prints. By adopting a configuration in which the communication terminal device is notified of the normal end when the data transfer to the device is completed, it is possible to realize a device that protects security during printing.

  In other words, according to the present invention, the individual identification information of the user is not stored in the authentication server or the printing device, and the individual identification information of the user can be managed only by the communication terminal device. Damage can be minimized, and it is not necessary to install an expensive HDD in the authentication server or the printing apparatus, so that it is possible to construct a print security system at a low cost.

A second invention is a communication terminal device that issues a print request to an authentication server equipped with an individual recognition device via a network, and when executing printing from an application, the individual information of the user and the individual information of the user a print data storage means for storing the linked print data, presence or absence of the print data to monitor and, if the print data has been newly added, and communication means for transmitting the print request to the authentication server, the Individual information receiving means for receiving individual information input in the individual authentication device transmitted to all communication terminal devices that have transmitted print requests from the authentication server, the individual information received from the authentication server, Individual information verification that collates with the individual information of the user stored linked to the print data and notifies the authentication server of the verification result And the step, when receiving the print permission from the authentication server, the print data transmitting unit for transmitting to the authentication server retrieves the print data, to a communication terminal device characterized in that it comprises a.

  That is, according to the second invention, in the communication terminal device, the print data storage means stores the individual information such as the user's fingerprint and vein and the print data when executing printing using the application, and the communication means. The user who monitors the presence or absence of the print data in the print data storage means, sends a print request to the authentication server when the print data is newly added, and the individual information reception means is sent from the authentication server And the individual information collating unit collates with the individual information of the user of all print data in the print data storage unit with respect to the received individual information, notifies the verification result to the authentication server, and print data When the transmission unit is permitted to print in the authentication server, the print data is extracted from the print data storage unit and transmitted to the authentication server. Apparatus can be provided to protect the security of the time.

  In other words, the individual identification information of the user is not stored in the authentication server or the printing device, and the individual identification information of the user can be managed only by the communication terminal device, so that the damage can be minimized even if the device is taken away. In addition, it is not necessary to install an expensive HDD or the like in the authentication server or the printing apparatus, and it is possible to construct a print security system at a low cost.

Further, in the second invention, the individual information collating means in the communication terminal device receives a normal end of the print data transmission from the authentication server when a plurality of the print data of the user is stored. Further, it is applied that the user confirms the presence or absence of the print data of the user in the print data storage means and transmits the print data to the authentication server.

That is, in the communication terminal apparatus, if the print data of the user is more stored in the print data storing means, when receiving the normal end of the print data transmitted from the authentication server, the user in the re-print data storing means print If there is print data, if there is print data, the print data sending means sends the print data to the authentication server, so that all the print data printed by inputting individual information once at the authentication server Output can be performed.

According to the present invention, the following effects are produced.
1) According to the present invention, when a print authentication request is made in a print security system that includes a printing device and an individual recognition device that are connected to each other via a network, and a communication terminal device. By configuring the authentication server to transmit authentication individual information (individual data such as fingerprints and veins) to all communication terminal devices that have instructed printing, the user only inputs authentication data in the individual recognition device. This eliminates the need to specify a communication terminal. In addition, the individual data is collated in the communication terminal device instructed to print as the place of authentication, and it is not necessary to install the authentication function on the authentication server and the printing device side, so that the memory capacity can be reduced and the low An inexpensive printing security system is realized.

That is, the individual identification information of the user is not stored in the authentication server or the printing device, and the individual identification information of the user can be managed only on the communication terminal device, so that damage can be minimized even when the device is taken away. In addition, since it is not necessary to install an expensive HDD in the authentication server or the printing apparatus, a system can be constructed at a low cost.
2) The communication terminal device notifies the authentication server of the collation result of the individual information, and when the individual data matches, the communication terminal device receives the print permission from the authentication server for the first time to receive the print data in the temporary hold state. Since the print data is transmitted to the printing apparatus, security is ensured at the time of printing, such as prevention of removal by other users.
3) If the user is printing from a plurality of different communication terminal devices by transmitting the authentication data to all the communication terminal devices that have issued a print instruction to the authentication server to which the user has entered authentication data (fingerprint, etc.) By inputting the authentication data, all print data can be printed at once without specifying the communication terminal device or print data.
4) When one communication terminal apparatus is shared by a plurality of users, all print data of the corresponding user can be output by one authentication with the authentication server.

When print permission is received from the individual information collating means 104 to be notified and the authentication server 2, the print data Taking out the print data from the device 101, and a print data transmitting unit 105 for transmitting to the authentication server 2.

  In the communication terminal device 1, each of the above means is stored as a print security program in a computer-readable recording medium such as an HDD, read into the memory 12 at the time of activation, and executed by the CPU 11.

  The authentication server 2 is a computer including an individual recognition device 4 that responds to a print request from the communication terminal device 1 via the network 5, and includes a print request reception unit 201 that receives the print request transmitted from the communication terminal device 1. The print request management unit 202 that manages the print request received by the print request reception unit 201, the individual information input unit 203 that inputs the individual information of the user, and the individual information input from the individual information input unit 203 Individual information inquiry means 204 that makes an inquiry to all communication terminal apparatuses 1 that have transmitted print requests managed by the means 202, and individual information that is sent by the individual information inquiry means 204 in response to a collation result from the communication terminal apparatus 1 Print permission means for transmitting print permission to the communication terminal device 1 having print data linked to individual information that matches 05, the print output unit 206 that receives the print data from the communication terminal device 1 transmitted in response to the print permission and transmits the print data to the print device 3 registered in the authentication server 2, and the print to the print device 3 When the data transmission is completed, the communication terminal apparatus 1 includes a print result notifying unit 207 for notifying the normal end of the print data.

  In the authentication server 2, each unit described above is stored in a recording medium such as a ROM as a print security program, is read into the memory 22 at the time of activation, and is executed by the CPU 21.

  The processing operation in each device of the print security system will be described below with reference to FIGS.

FIG. 4 shows a printing sequence according to the embodiment of the present invention (in the case where there is one user job for which a fingerprint is input). In the figure, “user 1” on the left indicates an operation by the user. Further, it is assumed that user 1 in communication terminal apparatus 1A and user 2 in communication terminal apparatus 1B register fingerprint data as individual information.
S101: In communication terminal apparatus B, when user 2 performs printing from an application, a print request is transmitted to authentication server 2.
S102: The authentication server 2 receives the print request from the communication terminal device 1B.
S103: Next, the authentication server 2 stores the IP address information (IP address, subnet mask, gateway address, etc.) of the communication terminal device 1B in the print request management table in the authentication server 2.
S104: Furthermore, the authentication server 2 generates a thread 1 for communication with the communication terminal device 1B, and notifies the communication terminal device 1B that the print request has been successfully received.
S105: The communication terminal device 1B temporarily holds the print data printed by the user 2 in the communication terminal device 1B when the authentication server 2 accepts the print request.

Here, the fingerprint data of the user 2 who performed printing is digitized in advance and is associated with a port monitor that communicates with the authentication server 2. When printing is performed from an application, the fingerprint data is associated with the print data. Thus, it is assumed that it is temporarily stored in the communication terminal device 1B separately from the print data.
S106: Next, when the user 1 executes printing from the communication terminal device 1A, the print data is spooled in the communication terminal device 1A.
S107: Similarly, a print request is transmitted to the authentication server 2.
S108: The authentication server 2 accepts a print request from the communication terminal device 1A.
S109: Next, the authentication server 2 stores the IP address information (IP address, subnet mask, gateway address, etc.) of the communication terminal device 1A in the print request management table in the authentication server 2.
S110: Furthermore, a thread 2 for communication with the communication terminal apparatus 1A is generated, and the communication terminal apparatus 1A is notified that the print request reception has been successful.
S111: When the authentication server 2 receives a print request, the communication terminal device 1A temporarily holds the print data printed by the user 1 in the communication terminal device 1A.

Similarly, the fingerprint data of the user 1 who performed printing is digitized in advance and is associated with a port monitor that communicates with the authentication server 2, and is associated with the print data when printing is performed from an application. In addition, it is assumed that it is temporarily stored in the communication terminal device 1A separately from the print data.
S112: Here, when the user 1 moves to the authentication server 2 side to receive the print data and puts a finger on the individual recognition device 4 (fingerprint recognition), the authentication server 2 digitizes the fingerprint data.
S113: Next, the authentication server 2 sequentially transmits fingerprint data to all the communication terminal devices 1 that have transmitted the print request.

In this embodiment, first, fingerprint data is transmitted to the communication terminal device 1B, and collation with fingerprint data associated with a print job held on the communication terminal device 1B is performed.
S114: In the case of this example, since the user 2 has printed from the communication terminal device 1B, the fingerprint data collation result is NG and is notified to the authentication server 2.
S115: Since NG has been transmitted from the communication terminal device 1B, the authentication server 2 transmits fingerprint data to the next communication terminal device 1A.
S116: Since the communication terminal device 1A has printed by the user 1, the collation result of the fingerprint data is OK, and the communication terminal device 1A notifies the authentication server 2 of the collation result (OK) and the user ID.
S117: The authentication server 2 receives the collation result of the communication terminal device 1A, and since there is no other communication terminal device, the authentication server 2 can receive the print data reception port of the communication thread with the communication terminal device 1A. Is notified of the print data transmission permission and the permitted user ID.

Here, the fingerprint data is transmitted from the authentication server 2 to the communication terminal device 1 in order, but the fingerprint data is transmitted to all the communication terminal devices at the same time without waiting for a response from the communication terminal device. May be.
S118: Upon receiving the print data transmission permission from authentication server 2, communication terminal apparatus 1A cancels the suspension of the print job of the permitted user ID on communication terminal apparatus 1A, and transmits the print data to authentication server 2.
S119: Upon receiving the print data, the authentication server 2 transfers the print data to the printing apparatus 3 that has been registered in the authentication server 2 in advance.
S120: When the transmission of all the print data is completed, the communication terminal device 24 is notified of the normal end of the print data transmission.
S121: The communication terminal device 1A receives a normal end of print data transmission from the authentication server 2, and returns a message to that effect to the authentication server 2 when the job of the user ID permitted to print is “none”.
S122: The authentication server 2 deletes the communication thread from the notification of job “none” and opens the print data reception port.
S123: In response to this, the communication terminal device 1A deletes the print data, writes it in the print log, and completes the process.

FIG. 5 shows a printing sequence according to an embodiment of the present invention (part 2: when there are a plurality of user jobs with fingerprints input). In this embodiment, the processes from S201 to S220 are the same as those in the case where the user's job with the fingerprint input in FIG.
S221: When the user 1 performs a plurality of prints in the communication terminal device 1A, the user ID of the user permitted to print on the communication terminal device 1A when receiving the normal end notification of the print data transmission from the authentication server 2 is received. Check if print data remains.
S222: The communication terminal apparatus 1A transmits print data to the authentication server 2 when the job of the user ID permitted to print is “Yes”.
S223: Upon receiving the print data, the authentication server 2 transfers the print data to the printing apparatus 3 that has been registered in the authentication server 2 in advance.
S224: When transmission of all print data is completed, the communication terminal apparatus 1A is notified of normal termination of print data transmission.

  In the above process, when a print job by the same user remains, the process of transmitting the print data to the authentication server 2 is repeated.

  Here, it supplements about the function of a communication thread. When the communication terminal device 1 is connected to the authentication server 2 via the network (LAN) 5 (socket connection), a communication thread is generated. Since the authentication server 2 exchanges information and data while maintaining SSL (Secure Socket Layer) encrypted communication with the communication terminal device 1, a communication thread is created each time a connection request is received from the communication terminal device 1. Will be.

A thread is a basic function of an OS (Operating System), and resources such as memory are secured for each thread. In a multi-thread OS (Linux (registered trademark) , Windows (registered trademark), etc.), it is possible to operate a similar process in parallel by setting up a plurality of threads.

  In the case of the present invention, since the same processing such as exchange of feature point data with a plurality of terminals is performed between the communication terminal device / server, information is exchanged with a plurality of terminals simultaneously by creating a plurality of communication threads. Is possible.

  In the individual information input means 203 described above, a security system that performs advanced personal authentication by converting user's physical features such as fingerprints, veins, retinas, voiceprints, etc. into digital data and using it as authentication information is constructed. Is possible.

  Further, by using digital data stored in a portable medium such as a contact type or non-contact type IC card as authentication information, it is possible to construct a security system in which the user can freely edit the authentication information.
