Patent Images
1. An authorization system of a navigation device comprising:
- a first identification (ID) module arranged to perform authorization for a first portion of the navigation device; and
a second ID module arranged to perform authorization for a second portion of the navigation device, wherein the first ID module generates challenge information to challenge the second ID module in order to determine whether the second portion is authorized, wherein the challenge information is generated by the first ID module according to a position, a velocity and/or a time of the navigation device;
wherein the first and the second ID modules perform bidirectional authorization of the first and the second portions, and further determine behavior of the navigation device according to a result of the bidirectional authorization.

Abstract
An authorization system of a navigation device includes a first identification (ID) module and a second ID module. The first ID module is arranged to perform authorization for a first portion of the navigation device, and the second ID module is arranged to perform authorization for a second portion of the navigation device. The first and the second ID modules perform bidirectional authorization of the first and the second portions, and further determine behavior of the navigation device according to a result of the bidirectional authorization. An associated authorization method for controlling the navigation device is further provided.
