<P>PROBLEM TO BE SOLVED: To provide an information processor and the like which can surely prevent data from leaking compared to conventional ones. <P>SOLUTION: An information processor of an embodiment comprises: a first storage unit on which encryption processing using encryption key data is performed; a second storage unit storing information for identifying users who can access the first storage unit; an encryption key transfer unit for transferring at least a part of the encryption key data stored in the first storage unit to the second storage unit before a power state of the information processor is shifted from a powered-on state to other power states; a communication unit configured to perform wireless communication with a base station device; and an encryption key control unit for transferring back the encryption key data transferred to the second storage unit to the first storage unit, when the information processor obtains a determination result indicating that information corresponding to the information stored in the second storage unit has been input, and also obtains a determination result indicating that the communication unit can intercommunicate with the base station, while in the other power states. <P>COPYRIGHT: (C)2013,JPO&INPIT |
