Electronic signature for endorsing and signing information medium containing electronic component

Abstract

The invention provides an electronic signature for endorsing and signing information medium containing an electronic component, which comprises an information processing component and a read-write module, wherein the information processing component contains an encryption algorithm module and stores signature information, private key information of an endorser and public key information of an endorsee; the read-write module writes data into the electronic component and / or reads the data from the electronic component; and the encryption algorithm module is used to perform encryption operation processing on the signature information by taking the private key information of the endorser and the public key information of the endorsee as a password to obtain ciphertext information, and the information processing component is used to convert the ciphertext information into signature data which is written into the electronic component by the read-write module. The adoption of the technology improves the uniqueness and the inimitability of the signature information, and ensures that the use of electronic bills is safer. A mode which is easy to identify and use is adopted to realize the effective signature of the electronic bills, which can remarkably reduce the risk during the use of the electronic bills and promote the development of modern financial industry.

Description

technical field [0001] The present invention relates to an electronic signature for endorsement and signature of an information medium containing electronic components, in particular to an electronic signature for encrypting endorsement signature information and delivering it to an electronic component embedded in the medium such as a radio frequency electronic tag 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.

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
