According to the present invention, when ′certificate of originality′ is generated, an electronic document or a paper document including electronic fingerprint (hash) of original document consisting of text or image code (QR code or bar code), and timestamp is generated, without the original document, thereby being capable of certifying originality just with ′certificate of originality′ without the original document, and preventing in advance the original document from being exposed to the outside, when verifying an original document. |
