METHOD AND SYSTEM FOR AUTHENTICATION AND IDENTIFICATION OF OBJECTS

摘要

The invention relates to a method for authentication and identification of an object, comprising the following steps: capturing a first capture image of a selected inspection region (PB) of an object surface of the object (OBJ) for generating first capture image data (EBD) which represent the characteristic properties of the object surface in the inspection region; generating of third image data (DBD) which represent a third image which differs from the first capture image; determining first comparison data (VD1) by a first comparison operation (V1), wherein the first capture image data are compared to the third image data using a predefined comparison method; capturing a specimen image of an inspection region (PB) of an object surface of an inspection object (PRO) to be inspected to generate inspection image data (PBD) which represent the characteristic properties of the object surface of the inspection object to be inspected in the inspection region; determining second comparison data (VD2) by a second comparison operation (V2), wherein the inspection image data (PBD) are compared to the third image data (DBD) using the predefined comparison method; and authentication of the inspection object by comparing the first comparison data (VD1) to the second comparison data (VD2) to determine authenticity properties and by evaluating the authenticity properties.
