차분 혼합 알고리즘을 이용한 전자상거래 문서의 디지털 서명에 관한 연구

This paper presents a digital signature scheme for document image used in electronic commerce which directly embeds a signature onto the document. The time to take in signature is reduced by spreading of signature. Non-repudiation in origin,the 3rd condition of digital signature is realized by proposed digital signature scheme. The transmitter embeds the signature secretly and transfers it, and the receiver makes a check of any forgery on the signature and the document. This scheme is compatible with the ITU-T.4(CCITT G3 or G4 facsimile standards).
