Abstract

A peripheral device includes an interface for connection to a wired or wireless LAN, a local interface for wireless connection, and a control unit configured to check a legitimacy of a user based on a user-specific certificate stored in a communication-function-equipped device upon being accessed through the local interface by the communication-function-equipped device using near-field wireless communication, and to allow a predetermined process to be performed upon successful authentication of the legitimacy.

Claims

1. A peripheral device, comprising:

an interface for connection to a wired or wireless LAN;

a local interface for wireless connection; and

a control unit configured to check a legitimacy of a user based on a user-specific certificate stored in a communication-function-equipped device upon being accessed through the local interface by the communication-function-equipped device using near-field wireless communication, and to allow a predetermined process to be performed upon successful authentication of the legitimacy.

2. The peripheral device as claimed in claim 1, wherein the predetermined process is an encryption of a communication path.

3. The peripheral device as claimed in claim 1, wherein the predetermined process is an authentication check of credibility and/or legitimacy of electronic data.

4. The peripheral device as claimed in claim 1, wherein the communication-function-equipped device stores therein information about a plurality of certificates.

5. The peripheral device as claimed in claim 4, wherein the control unit links the certificates to respective encryption strengths for control purposes.

6. The peripheral device as claimed in claim 5, wherein the control unit links the certificates to respective processing performances of use of the certificates for control purposes.

7. The peripheral device as claimed in claim 5, comprising an operation display unit configured to be operated by a user, wherein the information about the plurality of certificates is displayed on the operation display unit, thereby allowing a user to select one of the certificates on the operation display unit.

8. The peripheral device as claimed in claim 4, comprising an operation display unit configured to be operated by a user, wherein the operation display unit displays an expiration date or information about disabled status with respect to the certificates.

9. The peripheral device as claimed in claim 8, wherein the operation display unit displays information about an update or reissue of a given certificate, and allows a user to perform a procedure to update or reissue the given certificate.

10. The peripheral device as claimed in claim 1, wherein the control unit adds a record of use of an application to a history of certificate uses in response to the application being used by using the certificate, and stores therein the history of certificate uses.

11. The peripheral device as claimed in claim 1, wherein the peripheral device is one of a printer, a scanner, and a facsimile, or a digital multifunctional device equipped with at least two functionalities of the printer, the scanner, and the facsimile, or a personal computer, and wherein the communication-function-equipped device is one of an IC card, an RFID, an NFC-R/W, and a mobile terminal.

12. A network system, comprising:

a network including one of a wired LAN and a wireless LAN; and

a peripheral device connected to the network,

wherein the peripheral device includes;

an interface for connection to a wired or wireless LAN;

a local interface for wireless connection; and

a control unit configured to check a legitimacy of a user based on a user-specific certificate stored in a communication-function-equipped device upon being accessed through the local interface by the communication-function-equipped device using near-field wireless communication, and to allow a predetermined process to be performed upon successful authentication of the legitimacy.

13. A method of processing communication for a peripheral device which includes an interface for connection to a wired or wireless LAN and a local interface for wireless connection, the method comprising:

checking a legitimacy of a user based on a user-specific certificate stored in a communication-function-equipped device upon being accessed through the local interface by the communication-function-equipped device using near-field wireless communication; and

allowing a predetermined process to be performed upon successful authentication of the legitimacy.
