Abstract
A method and system for generating and processing an authenticity certificate. A request for a step certificate is received from a requester entity. The step certificate authenticates an involvement of the requester entity about an object. The request includes an object identifier, a requester entity type of the requester entity, and a requester identity certificate of the requester entity. The object identifier is hashed. A signature is created and includes the hashed object identifier, the requester entity type, a certifier identity certificate, and the requester identity certificate. A hashing result is generated by hashing a concatenation of the object identifier, the requester entity type, the certifier entity certificate, the requester identity certificate, and the signature. The step certificate is generated and includes the hashing result. The step certificate is encrypted. The encrypted step certificate is sent to the requester entity for subsequently storing the step certificate on a media.
