Abstract
A method and system for generating data for generating an authenticity certificate to be stored on a media. The authenticity certificate authenticates an object. A request for a step certificate includes a media identifier, a media key block, an object identifier, a requester entity type, and a requester identity certificate. The object identifier is hashed. A created signature includes the hashed object identifier, the requester entity type, a certifier identity certificate, and the requester identity certificate. A generated hashing result is a concatenation of the object identifier, the requester entity type, the certifier entity certificate, the requester identity certificate, and the signature. The step certificate including the hashing result is generated and encrypted. The encrypted step certificate and an encrypted random key are sent to a requester of the step certificate. The object may be determined to be an authentic object, a counterfeited object, or a stolen object.
