Patent ID: 7519993

Claim:
An information processing terminal comprising: a first information processing mechanism capable of executing a general-purpose first application; a second information processing mechanism capable of executing a second application requiring security authentication of information; a management mechanism managing processes in said first and second information processing mechanisms; a protection mechanism securing and protecting information in execution of said second application, which is constituted independently of said first and second information processing mechanisms and said management mechanism, and contains a trigger detecting unit which detects a trigger operation to start said second information processing mechanism and outputs the detection of the trigger operation to said management mechanism; and drivers configured as input/output interfaces, the drivers being configured to perform input and output of data by said first application and said second application and configured to switch between an ordinary mode and a protective operation mode, wherein said management mechanism further comprises an execution management unit for effecting an operation of said first and second information processing mechanisms, when said trigger detecting unit detects said trigger operation, in such a way as to restrict execution of said first application and start said second application, only said second application is able to link with said drivers when said drivers are in the protective operation mode, and said management mechanism is configured to switch said drivers into the protective operation mode.
