Abstract
A smartphone into which an application is installed includes a first and second authentication processing unit. The first authentication processing unit is configured to determine whether or not a current activation time of the application is past expiration time; permits authentication if the current activation time is not past the expiration time; and denies authentication if the current activation time is past the expiration time. The second authentication processing unit is configured to determine whether or not the current activation time is after previous activation time; permit authentication if the current activation time is after the previous activation time; and deny authentication if the current activation time is not after the previous activation time, wherein second authentication processing allows authentication to be denied if the current activation time (tampered and unauthorized activation time) is time before the previous activation time, as a result of turning back an internal clock of the smartphone.
