Abstract
A tamper prevention system includes a mounting unit, a portable terminal device, a first data input unit, an authentication unit, a detecting unit, and a setting unit. The portable terminal device enables a user to input operation data, performs an operation in accordance with the operation data when a first mode is set, and fails to perform the operation when a second mode is set. The first data input unit enables the user to input first data. The authentication unit authenticates the user when the first data matches authentication data. The setting unit sets the portable terminal device to the first mode when the authenticating unit has authenticated the user, and sets the portable terminal device to the second mode when the authenticating unit has failed to authenticate the user and the detecting unit has detected that the portable terminal device is removed from the mounting unit.
