A method dedicated to authentication of products submitted to a data inscription during their manufacturing process is suggested. It includes a management of the origin of the machine providing the reference product signature. The strength of the method is based on some links established by turns at the registration stage between all the elements to protect. Specific variations coming from product data photo-inscription physically induce a fundamental link between material and immaterial product components. This link is exploited via a specific signature extraction.
