Title:
METHOD FOR VALIDATION OF AUTHENTICITY OF AN IMAGE PRESENT IN AN OBJECT, OBJECT WITH INCREASED SECURITY LEVEL AND METHOD FOR PREPARATION THEREOF, COMPUTER EQUIPMENT, COMPUTER PROGRAM AND APPROPRIATE READING MEANS
Document Type and Number:
WIPO Patent Application WO/2020/251380
Kind Code:
A1
Abstract:
The invention comprises the materialization of an original object (1) with an increased security level based on the processing of an original image (3) and of a digital marker with encoded information relating to the original image (5). The invention comprises a method for validating an object to be validated (2) having an image to be validated (4) and a digital marker to be validated (6), which compares encoded Information calculated from at least one image to be validated (4) with encoded information corresponding to at least one original image (3), by means of the processing of the encoded information present in at least one digital marker to be validated (6). The invention comprises computer equipment, computer programs and appropriate means for reading on a computer device. The invention aims to create mechanisms and instruments for controlling the authenticity of objects in the technical field of security printing.
