ABSTRACT:
An original data circulation system for storing or circulating original data which is digital information is provided. The original data circulation system includes an issuer apparatus, a user apparatus and a collector apparatus. The issuer apparatus generates originality information including first information corresponding to the issuer apparatus and second information corresponding to data and sends the originality information. The user apparatus verifies the validity of the source apparatus of the originality information and stores the originality information when the validity is verified. The collector apparatus verifies the validity of the source apparatus of the originality information and processes data corresponding to the second information when the validity is verified.
