Electronic seal with external safety component

Abstract

The invention provides an electronic signature with an external safety component. The electronic signature comprises the safety component and an electronic signature body, wherein the safety component comprises a safety information processing module and an encryption algorithm module which stores signature information and the key information of a signature owner; and the electronic signature bodycomprises an interface component, an information processing component and a printing module. The safety component transmits ciphertext information to the information processing component through the interface component, wherein the ciphertext information is acquired by performing encryption algorithm processing on signature information through the encryption algorithm module by taking the key information as a code; and the information processing component converts the ciphertext information into signature data printed by the printing module. In the technology adopted by the invention, on the basis of a medium-based electronic bill, the uniqueness and the unreproduction of the signature information are improved, so that the electronic bill is safer. Because an easy recognition and use way is adopted to realize effective signature of the electronic bill, risks in an electronic bill using process can be obviously reduced and the development of the modern financial industry can be promoted.

Description

technical field [0001] The present invention relates to an electronic signature of an external security component, in particular to an electronic signature of an external security component for ticket authentication, which encrypts the signature information and prints it on an information medium and transmits it to an electronic component embedded in the medium. chapter. 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....

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

Such as online banking and electronic key authentication technology to ensure the security of online banking is 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
