When a pre-determined time period has elapsed after a user access is last detected, a mobile device (2000) performs protection processing on account-related information. The mobile device (2000) comprises an access detection unit (2060) that detects that a user accesses the mobile device (2000), and a time period determination unit (2040) 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 (2000). The mobile device (2000) further comprises a storage location acquisition unit (2080) that acquires a location in the data storage unit (2100) in which the account-related information is stored, and a protection unit (2020) 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 (2080), when the time period determination unit (2040) determines that a pre-determined time period has elapsed from the last user access time point. |
