Electronic signature of external safe component for signing electronic paper

Abstract

The invention provides an electronic signature of an external safe component for signing electronic paper, comprising a safe component, an electronic signature body, a connector component, an information processing component and an electronic paper electronization module which can electronize the electronic paper. The safe component encrypts and operates signature information through an encryption algorithm module by taking key information as a password to obtain ciphertext information and transmits the ciphertext information to the information processing component by the connector component; and the ciphertext information is converted by the information processing component into graphical signature data for the electronic paper electronization module to electronize. By adopting the technology and on the basis of the medium-based electronic note, the uniqueness and the non-imitability of signature information can be improved and the use of the electronic notes is safer. The effective signature of the electronic notes can be realized in an easily-dentified and used mode, thus the risk of the electronic notes in the use can be effectively used and the development of modern financial industries can be promoted.

Description

technical field [0001] The present invention relates to the electronic signature of an external security component for signing electronic paper, in particular to an external security component used for bill authentication that encrypts the signature information and digitizes it on the electronic paper and transmits it to the electronic component embedded in the medium. Electronic signatures for security components. 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. [0003] However, due to the value and circulation of financial instruments themselves, the se...

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
