摘要： The present invention relates to a method for determining the authenticity of an object, the method comprising the step of:

providing anthentication code,
determining the positions of particles being distributed in an object,
encoding of the positions to provide a check-code,
using the check-code and the authentication-code to determine the authenticity of the object.
A generator polynomial, a step of determining if the particles are distributed in a three-dimensional pattern, or photodetectors with different angles, can be used.
