Tamper prevention system
First Claim
1. A tamper prevention system comprising:
- a mounting unit;
a portable terminal device detachably mounted to the mounting unit and comprising;
an operation input unit that enables a user to input operation data; and
a performing unit configured to perform an operation in accordance with the operation data;
a first data input unit that enables the user to input first data;
an authentication data storing unit that stores authentication data;
an authentication unit that authenticates the user when the first data matches the authentication data;
a detecting unit that detects whether or not the portable terminal device is removed from the mounting unit; and
a setting unit that sets the performing unit to a first mode when the authenticating unit has authenticated the user, and that sets the performing unit to a 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,wherein the performing unit performs the operation in accordance with the operation data when the setting unit sets the performing unit to the first mode, and fails to perform the operation in accordance with the operation data when the setting unit sets the performing unit to the second mode.

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.

18. A tamper prevention method executed by a portable terminal device, the portable terminal device being detachably mounted to a mounting unit and having an operation input unit and a performing unit, the operation input unit enabling a user to input operation data, the performing unit configured to perform an operation in accordance with the operation data, the method comprising:
-
authenticating the user when first data inputted by the user matches authentication data; detecting whether or not the portable terminal device is removed from the mounting unit; setting the performing unit to a first mode when the user is authenticated, and setting the performing unit to a second mode when removal of the portable terminal device from the mounting unit is not detected and the user is not authenticated, the performing unit performing the operation in accordance with the operation data when the performing unit is set to the first mode, the performing unit failing to perform the operation in accordance with the operation data when the performing unit is set to the second mode.
