Method for endorsement signature on information medium

Abstract

The invention provides a method for endorsement signature on an information medium, comprising the following steps of: adopting a first calculation module of an asymmetrical encryption algorithm to carry out operation processing by taking a private key of an endorser as a password for signature information to obtain a first calculation result, and adopting a second calculation module of the asymmetrical encryption algorithm to carry out operation processing by taking a public key of the endorser as a password for the calculation result to obtain encrypted data; converting the encrypted data into printing signature information; and printing the signature information on an information medium. The technique employing the method improves the uniqueness and non-imitation of signature, so that the use of an E-note is safer. The method adopts a mode with easy identification and use to realize an effective signature for an E-note, thereby greatly reducing the risk in the use of the E-note and promoting the development of modern financial industry.
