<p><P>PROBLEM TO BE SOLVED: To securely manage terminal storage data in a thin client terminal without deleting the data even if communication is disconnected for a long time. <P>SOLUTION: A storage unit 16 temporarily stores terminal storage data 16A which is a part or the whole of data to be processed in an application. If user operations are not executed for a predetermined period, a function lock unit 17B stops execution of processing corresponding to user operations. An authentication determination unit 17C causes an authentication processing unit 15 to execute user authentication on detecting an authentication request operation by a user while processing execution is stopped, if the user authentication is successful, restarts execution of processing corresponding to user operations, and if the user authentication is failed, deletes the terminal storage data 16A in the storage unit 16. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
