1. An information processing apparatus comprising:

  • a first recording unit configured to record information concerning an activity pattern of a registered user;

    a first obtaining unit configured to obtainprocessing circuitry; and

    memory storing instructions that when executed by the processing circuitry cause the processing circuitry to perform the steps ofgenerating an activity pattern of a registered user by continuously tracking movement of the registered user for a predetermined period and recording information concerning the tracking,obtaining information concerning a location at which a user begins an authentication process;

    ,a second obtaining unit configured to obtainobtaining a current time at which the user begins the authentication process;

    , a determination criterion calculating unit configured to calculatecalculating a determination criterion by weighing the information concerning the generated activity pattern of the registered user recorded in the first recording unit against the obtained information concerning the location obtained by the first obtaining unit and the obtained current time obtained by the second obtaining unit; and

    , an authentication-level determining unit configured to determinedetermining, from a plurality of authentication levels, an authentication level to be used in the authentication process based on the determination criterion, each authentication level corresponding to different authentication requirements, andapplying the determined authentication level to the authentication process.
