Abstract

There is provided a mobile communication device having a function capable of releasing lock on an IC card function by an authentication key other then a PIN if the IC card function is locked by a PIN authentication error in a mobile phone having a contactless IC card built in. When a PIN is locked in a mobile phone 1 having a contactless IC card built in, an IC application 11 is started up to transmit a second password other than a PIN to an authentication server 3. The authentication server 3 compares the second password received from the mobile phone 1 with another second password stored in a database 31. If both second passwords agree with each other, a PIN lock release command is transmitted to the mobile phone 1. Further, the mobile phone 1 switches the lock flag of the contactless IC card 13 to OFF from ON by the command received. The PIN lock of the IC card function is thereby released.

The mobile communication device according to claim 1, wherein, based on an input from the user, the user authentication information obtaining section obtains a second password different from a first password used for the use authentication, and regards the obtained second password as the user authentication information.

5. The mobile communication device according to claim 1, wherein the user authentication information obtaining section obtains biological information of the user, and regards information calculated from the obtained biological information as the user authentication information.

6. The mobile communication device according to claim 4, wherein the user management server compares the user authentication information transmitted from the user management server wireless communication section with other user authentication information registered in advance, thereby to authenticate the user, and transmits an instruction about release of the lock to the mobile communication device if the user is authenticated.

7. The mobile communication device according to claim 1, wherein, based on an input from the user, the user authentication information obtaining section obtains a second password different from a first password used for the use authentication, compares the obtained second password with another second password registered in advance, thereby to authenticate the user, and if the user is authenticated, regards as the user authentication information the fact that the user has been authenticated.

8. The mobile communication device according to claim 1, wherein the user authentication information obtaining section obtains biological information of the user, compares the obtained biological information with other user biological information registered in advance, thereby to authenticate the user, and if the user is authenticated, regards as the user authentication information the fact that the user has been authenticated.

9. The mobile communication device according to claim 7, wherein the user management server receives the user authentication information from the user management server wireless communication section, and transmits an instruction about release of the lock to the mobile communication device if the user corresponding to the user authentication information satisfies a predetermined permission condition.

10. The mobile communication device according to claim 9, wherein the predetermined permission condition is that the user corresponding to the user authentication information is not a user who has been registered in advance and has been prohibited from release of lock.

11. The mobile communication device according to claim 1, wherein the predetermined lock condition is that the number of times the use authentication fails reaches a predetermined value.

12. A mobile communication device control program that makes a computer of a mobile communication device execute control of the mobile communication device that is brought close to an information processing device to make wireless communication with the information processing device, comprising:
