METHOD AND DEVICE FOR READING AUTHENTICATION MEANS AND ADAPTED IDENTIFICATION MEANS

摘要

The invention concerns a method for reading single volume and non-reproducible identification means (100) comprising a mixture of at least two materials (110 and 120) distinguishable from each other (110 and 120), characterised in that it consists in recognising in two dimensions the internal heterogeneous structure of said identification means (100) and in isolating and demonstrating its third dimension thereby eliminating the risk of imposture. Said characteristic enables to reduce storage volume and the periods of time required for scanning, acquisition and comparison operations performed in such processes. The invention also concerns a device for implementing said method. The invention is useful for identifying and authenticating objects, living beings, transactions.
