Multifunctional electronic signature supporting endorsement

Abstract

The invention provides a multifunctional electronic signature supporting endorsement, which is characterized by signing on media including electronic paper and electronic components. The electronic signature comprises an information processing component, a printing module, an electronic paper electronizing module and a read-write module. With the private key information of endorsers and the public key information of endorsees as the passwords, an encryption algorithm module carries out encryption algorithm processing on the signature information to obtain ciphertext information, and the information processing component converts the ciphertext information into patterned signature data electronized by the electronic paper electronizing module; and / or the information processing component converts the ciphertext information into the signature information printed by the printing module. The electronic signature improves the uniqueness and non-imitating property of the signature information and ensures safer use of electronic bills. A method which is easily identified and used is adopted to realize valid signature of the electronic bills, thus obviously reducing the risks for using the electronic bills and promoting the development of the modern finance.

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
