Electronic signature supporting continuous endorsement signature of electronic paper

Abstract

The invention provides an electronic signature supporting continuous endorsement signature of electronic paper. The electronic signature comprises an information processing part, an electronic paper electronizing module and an information sensing module, wherein the information sensing module acquires prior endorsement signature data and transfers the prior endorsement signature data to the information processing part, and by using public key information of a prior endorser and private key information of an endorser as the key, the information processing part decrypts the prior endorsement signature data to obtain the prior signature information; and a cryptographic algorithm module performs the cryptographic operation treatment of the signature information and the prior signature information by using the private key information of the endorser and the public key information of an endorsee as the code to obtain the ciphertext information, and the information processing part converts the ciphertext information into the imaging signature data capable of being electronized by the electronic paper electronizing module. The electronic signature improves the uniqueness of the signature information and makes the signature information more difficult to replicate; moreover, by adopting the mode of easy identification and use, the electronic signature realizes the effective signature of electronic bills, obviously lowers risk in using the electronic bills and enforces the development of modern financial industry.

Description

technical field [0001] The present invention relates to an electronic signature that supports continuous endorsement and signature of electronic paper, in particular to an electronic signature for document authentication that encrypts continuous endorsement signature information and digitizes it on electronic paper and transmits it to electronic components embedded in the medium . Background technique [0002] With the development of modern economy, the healthy, orderly and safe development of the financial industry is of great significance to today's economic development. In the development of the financial industry, from cash transactions to the comprehensive popularization of various financial instruments, such as letters of credit, promissory notes, checks, etc., have become the main payment tools for various businesses in the modern economy. However, due to the value and circulation of financial instruments themselves, the security of financial instruments is greatly c...

Problems solved by technology

However, based on cost and technical reasons, the anti-counterfeiting marks of letters of credit, promissory notes, and checks are not complicated and can be easily copied by counterfeiters.

There are two problems in the signature or endorsement used to confirm the validity of letters of credit, promissory notes, and checks: on the one hand, the signatures or endorsements performed by the same person in different moods and at different time points cannot be guaranteed to be completely consistent, resulting in valid The signature or endorsement is rejected. On the other hand, because the signature or endorsement must be basically the same each time, it provides opportunities for counterfeiters to forge

For example, online banking and electronic key authentication technology to ensure the security of online banking are becoming an important direction for the development of the modern financial industry, but at the same time, network hackers, viruses, phishing programs, etc. also greatly threaten the security of online banking
