Abstract
A method and system for generating data for use in generating an authenticity certificate. A request is received for a step certificate that authenticates an involvement of the requester entity about an object. The request includes a media identifier, a media key block, 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. 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 using a random key. The encrypted step certificate and an encrypted random key are sent to the requester entity for subsequent writing the step certificate and the encrypted random key on a media.
