The invention relates to a computer-implemented method, system and computer program for tokenization of a physical object. The method comprises generating or receiving object identification data based on an inspection of the physical object, the object identification data comprising at least one cryptographic hash value as a collision-resistant virtual representation of the physical object; and generating a non-certified token being assigned to the physical object and representing the object identification data. The invention further relates to a computer-implemented method, system and computer program of certifying a token including object identification data. Moreover, the invention relates to a computer-implemented method, system and computer program of tokenization of a process.

Methods and systems for token-based anchoring of a physical object in a distributed ledger environment

The present invention relates to the field of tracing and anti-counterfeit protection of physical objects, and particularly to preparing and performing a secure authentication of such objects. Specifically, the invention is directed to a method and a system for preparing a subsequent secured authentication of a physical object or group of physical objects by a recipient thereof, to a method and system for authenticating a physical object or group of physical objects, to a method and system of securely providing a time-variant combination scheme for authenticating a physical object or group of physical objects according to the above methods, and to related computer programs corresponding to said methods. The invention is based on the concept of increasing the security level by increasing the information entropy of the data on which the anti-counterfeit protection is based by means of random data communicated to authenticating entities in an algorithmically hidden way.
