System for authenticating signature on information medium

Abstract

The invention provides a system for authenticating a signature on an information medium, comprising an authentication server and the information medium. The authentication server comprises an information collection component, an encryption and decryption algorithm computing component and a data storage stack. The surface of the information medium is provided with ciphertext information obtained by encrypting signature information. The encryption and decryption algorithm computing component comprises an encryption and decryption algorithm computing module. The authorized signature information of the information medium owner is stored in the data storage stack. The information collection component collects the ciphertext information and converts the ciphertext information into the ciphertext information data processed by the authentication server. The encryption and decryption algorithm computing component decrypts the ciphertext information data to obtain plaintext of the signature information. The authentication server realizes the authentication of the information medium by judging whether the plaintext of the signature information is consistent with the authorized signature information prestored in the data storage stack by comparison. In the system, the uniqueness and the non-imitability of the signature information are improved, thus ensuring the electronic bill to be used more safely. The system obviously reduces the risks in using the electronic bill.

Description

technical field [0001] The present invention relates to a system for authenticating a signature on an information medium, in particular to a system for authenticating a bill which encrypts signature information and prints it on an information medium and transmits it to an electronic component 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 challenged. Cases of financial fraud by forging letters of credit, ...

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
