Method and system for preventing copy of platform

Abstract

A method and system for preventing copy of a platform are provided. A platform test apparatus includes a drive unit which drives a platform to cause the platform to move in a predetermined manner, at least one light source which emits light to the platform while the platform is driven so that the light is transmitted through a predetermined part of the platform, a sensor which senses the light transmitted through the platform, a calculation unit which calculates an absorption property of the platform based on a detected result of the sensor, a reading unit which reads absorption property information of the platform stored in an information storage unit of the platform, and a comparison unit which compares the absorption property calculated by the calculation unit with the absorption property information read by the reading unit to determine whether the platform is copied.

Dependencies are inferred from the claim text.
