Abstract:
1. A method of marking an object to identify same comprising: providing a local heating source and forming a multi-symbol encoded encrypted message with identification parameters of the object to apply same on a surface of the object impacting the surface by the local heating source, said forming being performed by modifying optical properties and structural configuration of the surface to thereby create contrast microscopic imprints thereon comprising cluster nanostructures of elements of material the surface of the object is made of, encoding the encoded encrypted message being performed based on a primary code array of correspondence of each of the symbols of the encoded message to a multibit combination of 0 and 1, the 0 and 1 representing absence and presence of the local heating source impact imprint; and encrypting the encoded encrypted message being effected by creating particular code arrays based on the primary code array by means of random perturbation of the components thereof.
