TAMPER PREVENTION SYSTEM
First Claim
1. A tamper prevention system comprising:
- a mounting unit;
a portable terminal device that is detachably mounted to the mounting unit, the portable terminal device including;
an operation input unit that enables a user to input operation data; and
a performing unit that performs operation in accordance with the operation data when the performing unit is set to a first mode, and that fails to perform operation in accordance with the operation data when the performing unit is set to a second mode;
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 the first mode when the authenticating unit has authenticated a user, and that sets the performing unit 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.

Abstract
A tamper prevention system includes a mounting unit, a portable terminal device, a first data input unit, an authentication data storing unit, an authentication unit, a detecting unit, and a setting unit. The portable terminal device is detachably mounted to the mounting unit. The portable terminal device includes an operation input unit, and a performing unit. The operation input unit enables a user to input operation data. The performing unit performs operation in accordance with the operation data when the performing unit is set to a first mode, and fails to perform operation in accordance with the operation data when the performing unit is set to a second mode. The first data input unit enables the user to input first data. The authentication data storing unit stores authentication data. The authentication unit authenticates the user when the first data matches the authentication data. The detecting unit detects whether or not the portable terminal device is removed from the mounting unit. The setting unit sets the performing unit to the first mode when the authenticating unit has authenticated a user, and that sets the performing unit 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.

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

18. A computer readable recording medium storing a set of program instructions executable on a portable terminal device, the portable terminal device being detachably mounted to a mounting unit and having a performing unit, the performing unit performing operation in accordance with the operation data when the performing unit is set to a first mode, and the performing unit failing to perform operation in accordance with the operation data when the performing unit is set to the second mode, the program comprising instructions for:
-
inputting first data by a user of portable terminal device, portable terminal device being detachably mounted to a mounting unit; authenticating the user when the first data matches authentication data; detecting whether or not a portable terminal device is removed from a mounting unit; and setting a performing unit to the first mode when the user is authenticated, and setting the performing unit to the second mode when removal of the portable terminal device from the mounting unit is not detected and the user is not authenticated.
