摘要

PURPOSE: A system and a method for generating a paper document of an electronic document signed by a public key, and an authenticating electronic signature on the paper document are provided to print an electronic document, signed by a public key, on a paper for a backup, a circulation and a check, and to authenticate the printed paper document. CONSTITUTION: The system comprises a paper document generator(1000), and a paper document authenticator(2000). The paper document generator(1000) includes a paper document generation module(100) and a paper printing module(200). The paper document authenticator(2000) includes a paper document input module(300) and a paper document authentication module(400). The paper document generation module(100) generates an image to be printed on a paper for the electronic document signed by the public key. The paper printing module(200) prints the generated image on the paper. The paper document input module(300) receives the paper document, output via the paper printing module(200), converts the paper document into the digital document, and transfers the digital document to the paper document authentication module(400). The paper document authentication module(400) authenticates the digital document, transferred by the paper document input module(300).
