DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a protection system according to the present invention will be described in detail with reference to the accompanying drawings.
In the following, a specific example of a printing system or an e-mail system will be described as an embodiment of the protection system according to the present invention.

(First Embodiment) FIG. 1 is a diagram showing a configuration of a printing system according to the present invention. As shown in the figure,
The printing system includes data terminals 10, 10a, 10b,...
, And a print server 50 that manages the print jobs, each being connected to a network 70 such as a LAN (internal network). Note that the printer other than the printer 30 is also connected to the network 70.

The data terminal 10 has a C controlling its operation.
PU 11, RAM (random access memory) 13 into which programs and data to be referred to by CPU 11 at the time of execution are loaded, ROM (read only memory) 15 storing predetermined programs to be executed by CPU 11, and auxiliary storage means A hard disk 17, a display input unit 19 including a keyboard, a display, and the like, a network interface 21 for communicating via a network 70, and an external interface 23 for connecting to an external device. The data terminal 10 is connected to a fingerprint reader 61 that reads fingerprint information of a human finger and outputs the fingerprint information as fingerprint data. The other data terminals 10a and 10b connected to the network 70 have the same configuration as the data terminal 10, and have the fingerprint reader 63,
64... When operating the data terminal 10, the user operates a keyboard, a mouse, and the like to input various data and settings while looking at the screen displayed on the display in the display input unit 19.

The printer 30 has a CP for controlling its operation.
U31, a RAM 33 into which programs and data referred to by the CPU 31 at the time of execution are loaded, a ROM 35 storing a predetermined program to be executed by the CPU 31, a hard disk 37 as auxiliary storage means, and an operation panel 39 operated by a user. , A network interface 41 for communicating via the network 70, and an external interface 43 for connecting to an external device.

The print server 50 has the same configuration as the data terminal 10, and includes a CPU for controlling the overall operation, a RAM and ROM for storing programs and data, a hard disk 57, and the like. The print server 50 stores a fingerprint information file 67 on the hard disk 57. The fingerprint information file 67 stores information such as an identification number indicating a user, a user name, fingerprint data of the user, and a registration number (fingerprint registration number) of the fingerprint data in association with each other. The printer 50 is connected to the fingerprint reader 62 via the external interface 43.

In the printing system configured as described above, when a print job is transmitted from the data terminals 10, the print server 50 receives the print job data,
The print job data is temporarily stored in the hard disk 57 and transmitted to the printer specified in the print job data. In particular, in the printing system of the present embodiment, when fingerprint data is added to the print data and transmitted at the data terminal 10, the same fingerprint information as the fingerprint information is input to any of the printers connected to the network. Unless this is done, the print data is not printed out from the printer.

FIG. 2 is a flowchart showing a process when the data terminal 10 transmits a print job. The data terminal 10 determines whether or not the user has performed an operation for transmitting a print job (S11), and performs the following processing when the operation is detected. That is, first,
It is determined whether the user adds fingerprint information to the print data, that is, whether the user performs an operation for adding fingerprint information to the print data (S12). If the fingerprint information is not added to the print data, step S16
Proceed to. When the fingerprint information is added to the print data, it is determined whether or not the input of the fingerprint information is based on the fingerprint registration number (S13). When using the fingerprint registration number, the fingerprint registration number designated by the user is stored in the RAM 13 for later work.
And so on (S14). If it is not based on the fingerprint registration number, the user's fingerprint data read from the fingerprint information reading device 61 is input (S17). Thereafter, fingerprint information (fingerprint registration number or fingerprint information) is added to the print data (S1).
5) The print job data including the print data is transmitted (S16). Here, the print job data includes various settings for printing in addition to the print data, for example, information such as designation of an output printer, information of a print requesting user, output terminal information of a print job, and transmission time. As described above, the fingerprint information is added to the print data in the data terminal 10 and transmitted.

Next, processing when the print server 50 receives print job data will be described. The printer server 50 receives the print job data transmitted from the data terminals 10 connected to the network and, when fingerprint information is added to the print data, prints the fingerprint from one printer connected to the network. Wait for information,
When the same fingerprint information as that of the sender of the print job is received, the print job is transmitted to the printer that transmitted the fingerprint information.

FIG. 3 is a flowchart showing the above processing in the print server 50. The print server 50 receives the print job data (S21), and determines whether fingerprint data is added to the print job data (S22). When the fingerprint data is added, the received print job data is stored in the hard disk 57 (S23), and it is determined whether or not the received fingerprint data is registered with reference to the fingerprint information file 67 (S24). .

The received fingerprint data is stored in the fingerprint information file 6
7, the sender of the print job data is notified that there is print data (S25). For example, a predetermined message is displayed on the data terminal of the sender. When the user confirms this message on the data terminal, the user moves to the printer to be output and causes the fingerprint reader connected to the printer to read his / her fingerprint. If the received fingerprint data is not registered in the fingerprint information file 67, the step (S25) is skipped.

Thereafter, the print server 50 waits for a certain period of time until fingerprint data matching the sender's fingerprint data is transmitted from any printer on the network (S26). When the print server 50 receives the matching fingerprint data from one printer within a predetermined time, the print server 50 transmits the print data to the printer (S27), and ends the processing. Upon receiving the print data, the printer prints out the print data. If the print server 50 does not receive the matching fingerprint data from any of the printers within a certain time, the print server 50 discards the received print data (S31).

On the other hand, if the fingerprint data is not added in step S22, it is determined whether or not the fingerprint registration number is added (S28). If the fingerprint registration number is added, it is confirmed whether or not there is fingerprint data corresponding to the fingerprint registration number (S29). That is,
It is checked whether there is fingerprint data corresponding to the fingerprint registration number in the fingerprint information file 67. If there is fingerprint data corresponding to the fingerprint registration number, the received print job data is stored in the hard disk 57 (S30), and the process proceeds to step S25. If there is no fingerprint data corresponding to the fingerprint registration number, the received print data is discarded (S31).

If the fingerprint registration number has not been added in step S28, the print data is transmitted to the printer specified in the print job data (S32).

As described above, in the printing system of the present embodiment, when a print job is transmitted from a data terminal and a user adds fingerprint information unique to the user to the print data and transmits the print data, the printer adds the fingerprint information to the print data. Unless the same fingerprint information is input, the print data is not printed. As described above, the printing apparatus and the printing timing can be controlled using the fingerprint information unique to the user. For this reason, only the person who has requested the printing can output from the printer, the printing timing can be controlled so as not to be seen by a third party, and the confidentiality can be further improved in the management of important documents.

(Second Embodiment) In the present embodiment, a protection system for an e-mail system that exchanges e-mail via a network will be described. The e-mail system according to the present embodiment adds a sender's fingerprint information at the time of sending an e-mail, and specifies an e-mail sender based on the fingerprint information added to the e-mail at the time of receiving the e-mail. This is to prevent the reception of e-mail.

FIG. 4 is a diagram showing a configuration example of an electronic mail system according to the present invention. The e-mail system includes a plurality of private networks (network A, network B
..) is a system for exchanging e-mail between users using a data terminal in a network formed by connecting. Each of the networks A, B,... Is connected to a mail server that manages transmission and reception of e-mails in addition to data terminals. For example, in the network A, a mail server 80 is connected together with the data terminals 10, 10a,. The configuration of the data terminals in each network is the same as that of the first embodiment. The configuration of the mail server in each network is the same as the configuration of the data terminal, but a predetermined program for managing e-mail is installed in the mail server. The hard disk of each mail server stores a fingerprint information file 67a, data of transmitted and received mails, and the like.

FIG. 5 is a flowchart showing the operation of the data terminal of the present embodiment when transmitting an e-mail. First, the document data of the outgoing mail specified by the sender is read (S41), and the fingerprint data of the sender is input from the fingerprint information reader (S42). The input fingerprint data is queried with reference to the fingerprint information file (S43). That is, it is determined whether or not the input fingerprint data is registered.
If the fingerprint data is registered (S44), the fingerprint data is added to the document data of the outgoing mail (S4).
5) Send to the designated destination (S46). If the fingerprint data is not registered (S44), the document data of the transmission mail is transmitted to the designated destination without adding the fingerprint data (S46).

FIG. 6 is a flowchart showing the operation when the mail server delivers a mail document sent from the data terminal to the data terminal of the receiver. This process is started when a user (recipient) accesses a mail server at a data terminal to receive a mail, and there is an unreceived mail.

First, the mail server determines whether or not fingerprint data is added to the data of the received mail (S51). If the fingerprint data has been added, the fingerprint data is queried with reference to the fingerprint information file to confirm the identity of the sender (S52). As a result of the inquiry, if the added fingerprint data matches one of the fingerprint data registered in the fingerprint information file (S5).
3) The document data of the received mail is transmitted to the data terminal of the recipient (S54).

On the other hand, when the fingerprint data is not added to the e-mail document (NO in S51), or when the result of the inquiry does not match the fingerprint data registered in the fingerprint information file (NO in S53). Confirms the user's instruction regarding the handling of the e-mail document (S5).
5). At this time, a message to confirm the instruction to the user is displayed on the display input unit of the data terminal. The user inputs an instruction in response to the display message.
When the user's instruction is "Receive" (S56), the document data of the received mail is transmitted to the data terminal of the recipient (S5).
4). If the user's instruction is "discard" (S56), the received mail document is discarded (S57), and a message to the effect that the data was not received by the destination user is sent to the sender of the mail. (S58).

As described above, in the present system, since the identity of the sender is confirmed using the fingerprint information unique to each individual, the mail whose sender is unknown is inadvertently opened and infected by the virus. Can be prevented.

(Third Embodiment) Another example of the electronic mail system according to the present invention will be described. The configuration of the e-mail system of this embodiment is the same as that of the second embodiment. In the e-mail system according to the present embodiment, authentication information is attached to a document at the time of sending an e-mail and transmitted, and whether or not the transmission is authenticated is determined based on the authentication information attached to the document at the time of receiving the e-mail. This makes it possible to recognize whether or not the sender of the mail is a secure sender. In the present embodiment, fingerprint information obtained by encrypting fingerprint data of a recipient with a password is used as authentication information. In this case, fingerprint information obtained by encrypting the fingerprint data of each user with a password is registered as authentication information in the fingerprint information file of the mail server. As described above, since the fingerprint information is stored in the mail server in the encrypted format, the security is further improved as compared with the case where the fingerprint information is used as it is.

FIG. 7 is a flowchart showing the operation of the data terminal according to the present embodiment when transmitting an e-mail. First, the mail server reads an e-mail document to be transmitted which is specified by the sender (S7).
1). Next, a predetermined password is read (S72). Next, the fingerprint data of the mail destination user, that is, the recipient, of the mail input by the user is read (S
73). These passwords and fingerprint data are input by the sender at the display input section of the data terminal. The read fingerprint data is encrypted with a password (S7).
4). An example of this encryption will be described later. The encrypted fingerprint information is added to the electronic mail document (S75). Thereafter, the e-mail document to which the encrypted fingerprint information is added is transmitted to the designated destination so that the recipient can open the e-mail (S76). When this mail document is received at the data terminal, its contents are displayed. That is, the received mail is opened.

The encryption of the fingerprint data in step S74 is performed, for example, in the following procedure. It is assumed that the fingerprint data and the password are composed of a plurality of codes. A1) One of several encryption methods is selected as an encryption method to be used according to the second digit code of the password. A2) In accordance with the method selected in A1), a code after the third digit of the password is added to the fingerprint data. Thus, the fingerprint data is encrypted.

The addition of the encrypted fingerprint data to the mail document data in step S75 is performed, for example, in the following procedure. B1) As a method for adding the fingerprint data encrypted in A2) to the data of the electronic mail document by the first digit code of the password, one of several adding methods is selected. B2) In accordance with the method selected in B1), the fingerprint data encrypted in A2) is added to the data of the e-mail document.

The above procedure will be described more specifically with reference to FIG. Here, as shown in FIG. 8A, the fingerprint information is “ABCDEFG” and the password is “123”. 1) First, an encryption method is selected based on the second digit code “2” of the password. Here, it is assumed that the method of inserting the code after the third digit of the password is selected every other code constituting the fingerprint data. 2) According to the method selected in 1), password 3
The digit after the digit, ie, “5” is inserted at every other code of the fingerprint data (see FIG. 8B). 3) Next, the method of adding the encrypted fingerprint data to the document data is determined by the first digit code “1” of the password. Here, it is assumed that the method of adding the encrypted fingerprint information B before and after the document data is selected. 4) According to the method selected in 3), the encrypted fingerprint data B is added before and after the document data (see FIG. 8C).

FIG. 9 is a flowchart showing the operation of the mail server of this embodiment when receiving an electronic mail. This process is started when a user (recipient) accesses a mail server at a data terminal to receive a mail, and there is an unreceived mail.

The mail server first reads a password based on the operation of the recipient (S91). Further, the recipient inputs the fingerprint data of the recipient read by the fingerprint information reader through the data terminal (S92). Based on the password and the fingerprint data, it is confirmed whether the user is a true recipient specified by the sender (S93). If the user is the true recipient (S94), the received data is decrypted by performing the reverse procedure of steps S24 and S25 (S95), and the decrypted received data is transmitted to the data terminal of the recipient. It is transmitted (S96). When the data terminal receives the received data, the content is displayed. That is, the received mail is opened. If it is determined that the recipient is not a true recipient (S94
NO), the received mail data is discarded (S97), and a message to the effect that the mail was discarded without being received is notified to the sender (S98).

(Fourth Embodiment) Still another example of the electronic mail system according to the present invention will be described. The configuration of the e-mail system of this embodiment is the same as that of the second embodiment.

In the electronic mail system of this embodiment, fingerprint information obtained by encrypting the fingerprint information of the sender is used as the authenticator information. Therefore, in the mail server connected to the receiver's network, the fingerprint information of the sender is registered as authentication information in the fingerprint information file. As described above, also in the present embodiment, by using the encrypted fingerprint information, the security is further improved as compared with the case where the encryption is not performed.

FIG. 10 is a flowchart showing the operation of the data terminal of the present embodiment when transmitting an e-mail. First,
A document of an e-mail to be transmitted by a user (sender) is read (S101). The fingerprint information obtained by encrypting the fingerprint data of the sender is input (S102). Attach the sender's encrypted fingerprint information to the e-mail document (S10
3). The e-mail document to which the encrypted fingerprint information has been added is transmitted to the designated destination (S104).

FIG. 11 is a flowchart showing the operation of the mail server of this embodiment when receiving an electronic mail. This process is started when a user (recipient) accesses a mail server at a data terminal to receive a mail, and there is an unreceived mail.

The mail server determines whether or not the received mail has the sender's encrypted fingerprint information added thereto (S111). If the fingerprint information is added, the fingerprint information is used as the fingerprint information. It is determined whether or not it is registered in the file (S112). If the encrypted fingerprint data is registered in the fingerprint information file 67a, the receiver confirms whether or not to receive the mail (S
113). At this time, a predetermined message is displayed on the display of the data terminal being operated by the recipient. When the recipient acknowledges the reception (S114), the data of the received mail is decrypted (S115), and the decrypted data is transmitted to the data terminal of the recipient (S116). When this data is received at the data terminal, its contents are displayed. That is, the received mail is opened.

On the other hand, if the fingerprint data is not added to the e-mail document, the user's instruction regarding the handling of the e-mail document is confirmed (S117). If the user's instruction is "discard" (S118), the received mail document is discarded (S119), and a message indicating that the mail transmitted to the destination user was not received is sent to the sender of the mail. Is notified (S120). If the user's instruction is "OK" indicating the acceptance of the reception (S118), the flow advances to step S116 to send the received data to the data terminal of the receiver.

In the electronic mail systems of the second to fourth embodiments, the mail server has the above-described function of specifying the sender, but this function may be provided on the data terminal side.

[0052]

According to the printing system of the present invention, when fingerprint information is added to print data at the time of transmission of print job data from the data processing device, the same fingerprint information as the added fingerprint information is added to the printer. Only when there is an input, the print data is printed. As a result, only the person who requested the printing can output the data from the printer. Therefore, it is possible to control the print output timing so that a third party does not see it while the printer is left after the output. Confidentiality in the management of important documents.

According to the electronic mail system of the present invention, the identity of the sender is confirmed by using fingerprint information unique to each individual,
This is performed using predetermined authentication information composed of fingerprint information, and when the identity of the sender is confirmed or when the sender is authenticated, an e-mail from the sender is received (opened), so the sender is unknown. It is possible to prevent the occurrence of troubles, such as inadvertently opening the e-mail and infecting with a virus.
