Abstract

본 발명은 금융 자동화 기기의 저널에 관한 것으로, 특히 종래 사용되던 저널 프린트 방식을 전자저널로 대체함으로써 종래 저널 프린트 방식에서의 문제점을 해결하는 디지탈 서명을 이용한 전자저널(Electronic Journal)방법을 제공함에 있다.The present invention relates to a journal of a financial automation device, and in particular, to provide an electronic journal method using a digital signature that solves problems in the conventional journal printing method by replacing the conventional journal printing method with an electronic journal. .

이와 같은 본 발명의 목적을 달성하기 위한 수단은 거래내용을 전자화일에 암호화 및 복호화하여 사용자의 고유한 코드 및 키에 의해서만 저장하는 단계와, 상기 저장단계에서 서명의 진위를 확인할 수 있도록 전자화일을 열수만 있고 잠글수는 없는 상기 고유키에 대응하는 공개 키로 전자화일을 복호화하고 서명되었음을 확인하는 단계로 이루어진다.Means for achieving the object of the present invention comprises the steps of encrypting and decrypting the transaction details in the electronic file and storing only by the user's unique code and key, and the electronic file to verify the authenticity of the signature in the storage step Decrypting the electronic file with a public key corresponding to the unique key that can be opened but not locked, and confirming that the signature has been signed.
