Electronic signature supporting continuous endorsement on media including electronic components

Abstract

The invention provides an electronic signature supporting continuous endorsement on media including electronic components, comprising an information processing component, an information sensing module and a read-write module. The information sensing module collects prior endorsement data on the media and transfers the data to the information processing component. With the public key information of prior endorsers and the private key information of endorsers as the secrete keys, the information processing component decrypts the prior endorsement data to obtain prior signature information. With the private key information of endorsers and the public key information of endorsees as the passwords, an encryption algorithm module carries out encryption algorithm processing on the signature information and the prior signature information to obtain ciphertext information, and the information processing component converts the ciphertext information into signature data written into the electronic components by the read-write module. The electronic signature improves the uniqueness and non-imitating property of the signature information and ensures safer use of electronic bills. A method which is easily identified and used is adopted to realize valid signature of the electronic bills, thus obviously reducing the risks for using the electronic bills and promoting the development of the modern finance.

Description

technical field [0001] The present invention relates to an electronic signature that supports continuous endorsement signatures on media containing electronic components, in particular to an electronic signature that encrypts endorsement continuous endorsement signature information and transmits it to electronic components embedded in the medium, such as radio frequency electronic tags, for bill authentication . 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 fi...

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
