Mobile device, program, and control method

摘要

When a pre-determined time period has elapsed after a user access is last detected, a mobile device performs protection processing on account-related information. The mobile device includes an access detection unit that detects that a user accesses the mobile device, and a time period determination unit that determines whether or not a pre-determined time period has elapsed from a last user access time point at which the user last accessed the mobile device. The mobile device further includes a storage location acquisition unit that acquires a location in the data storage unit in which the account-related information is stored, and a protection unit that performs the protection processing on the account-related information based on the storage location of the account-related information acquired by the storage location acquisition unit, when the time period determination unit determines that a pre-determined time period has elapsed from the last user access time point.

1. A mobile device in which a plurality of applications are installed, the mobile device comprising:
a processor and an associated memory, the processor and memory including, a storage location acquisition unit which acquires a storage location of each piece of account-related information, the account-related information is used by each of the applications; an access detection unit which detects a user access to the mobile device; a time period determination unit which determines whether a pre-determined time period has elapsed after the access detection unit detects a last user access; a protection unit that protects each piece of the account-related information based on each storage location acquired by the storage location acquisition unit, when the time period determination unit determines that the pre-determined time period has elapsed; and a timing storage unit which stores a time point of each user access which is detected by the access detection unit, wherein when the access detection unit detects a latest user access, the time period determination unit acquires from the timing storage unit a time point of a user access immediately previous to the latest user access as a time point of the last access, and compares the time point of the last access with a time point of the latest user access so as to determine whether the pre-determined time period has elapsed from the time point of the last access.
