Electronic signature for endorsing electronic paper through external security part

Abstract

The invention provides an electronic signature for endorsing electronic paper through an external security part, which carries out electronic signature on information medium containing the electronic paper. The electronic signature comprises a security part and an electronic signature body, wherein an encryption algorithm module carries out encryption operation treatment on a signature message byusing a private key message of an endorser and a public key message of an endorsee as passwords to obtain a cryptograph message, and the security part transmits the ciphertext message to a message processing part through an interface part; and the message processing part converts the ciphertext message into an electronic paper electronization module for carrying out electronized imaging signaturedata. Through the adoption of the technology of the invention, the electronic signature improves the uniqueness and inimitability of the signature message based on medium-based electronic bills and ensures that the use of the electronic bills is safer. A mode which is easy to recognize and use is adopted to realize the effective signature of the electronic bill, thereby remarkably reducing the risk in using the electronic bills and promoting the development of modern financial industry.

Description

technical field [0001] The present invention relates to an electronic signature for an electronic paper endorsement and signature by an external security component, in particular to an external security component for bill authentication that encrypts the endorsement signature information and digitizes it on the electronic paper and transmits it to the electronic component embedded in the medium. Electronic signature of security components.

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
