Claim Text:
1. A method for generating and processing an authenticity certificate, said method comprising: receiving, by a processor of a computer system from a requester entity, a request for a step certificate, said step certificate authenticating an involvement of the requester entity about an object, said request comprising, an object identifier, a requester entity type of the requester entity, and a requester identity certificate of the requester entity, wherein the object identifier identifies the object and is unique to the object; after said receiving the request, said processor hashing the object identifier; after said hashing the object identifier, said processor creating a signature comprising the hashed object identifier, the requester entity type, a certifier identity certificate of a certifier entity that has certified the authenticity of the object, and the requester identity certificate; said processor generating a hashing result by hashing a concatenation of the object identifier, the requester entity type, the certifier entity certificate, the requester identity certificate, and the signature; said processor generating the step certificate comprising the hashing result; said processor encrypting the step certificate using a random key; and said processor sending the encrypted step certificate to the requester entity for subsequently storing the step certificate on a media.
