Method for identifying and authenticating without specific reader an identifier

摘要

The method makes use of a three-dimensional marking (1,9,10,11) on the object or living thing which can be identified using visual or tactile senses (A,A'). The marking is difficult to reproduce. To confirm validity, the user uses a communication network (5) to access an image (2) of the marking held in a database (4), and compares marking and image by eye (D).
