System for authenticating endorsement signature on information medium

Abstract

The invention provides a system for authenticating an endorsement signature on an information medium, comprising an authentication server, the information medium and a safety device. The authentication server comprises an information collection component, a data storage stack and a safety device interface component. The safety device comprises a secrete key of an endorsee and a decryption algorithm implementation module. Authorized signature information is stored in the data storage stack. The information collection component collects ciphertext information and converts the ciphertext information into ciphertext information data processed by the authentication server. The authentication server transfers the ciphertext information data to the safety device, and the safety device decrypts plaintext of obtained signature information and transfers the plaintext of the signature information to the authentication server. The authentication server realizes authentication of the information medium by judging whether the plaintext of the signature information is consistent with the authorized signature information by comparison. By adopting the technology of the invention, the uniqueness and the non-imitability of the signature information are improved, thus ensuring the electronic bill to be used more safely. The system can obviously reduce the risks in using the electronic bill and promote the development of the modern financial industry.

Description

technical field [0001] The present invention relates to a system for authenticating an endorsement signature on an information medium, in particular to a system for authenticating an endorsement signature used for bill authentication after encrypting endorsement signature information, printing it on an information medium, and passing it to an electronic component embedded in the medium system. 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...

AI Technical Summary

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
