Information processing apparatus, method, program, and integrated circuit

摘要

A content display apparatus which processes protected information configured, with an aim to prevent access from any unauthorized program, to include: a process managing unit which manages a plurality of processes operable in the content display apparatus; and an access detecting unit configured to detect access to the protected-information access detecting unit which detects access to the protected information. The process managing unit includes an application execution control unit which temporarily stops the operation of each of at least one process other than a process which accesses the protected information among the plurality of processes when the access to the protected information is detected by the protected-information access detecting unit.

主权项

1. An information processing apparatus which processes protected information, the apparatus comprising:
a non-transitory memory storing executable instructions; and a processor which executes the executable instructions stored by the non-transitory memory, the processor including:
a process managing unit configured to manage a plurality of processes which operate in the information processing apparatus; andan access detecting unit configured to detect access to the protected information, wherein the process managing unit includes an execution control unit configured to temporarily stop the operation of each of at least one process other than a process which accesses the protected information among the plurality of processes when the access to the protected information is detected by the access detecting unit, and the process which accesses the protected information communicates with a process which is a communication destination originally for the at least one process other than the process which accesses the protected information while the operation of the at least one process is stopped, the processor further including
a communication detecting unit configured to detect the communication, and notify the execution control unit of a process identifier for identifying the communication-destination process upon detecting the communication, wherein the execution control unit is configured to cause the communication-destination process identified by the notified process identifier to stop operating only before the process identifier is notified, and cause the process to operate after the process identifier is notified.
