Abstract

The invention provides a system for authenticating an endorsement signature on an information medium, comprising an authentication server, the information medium and a safety device. The authentication server comprises an information collection component, a data storage stack and a safety device interface component. The safety device comprises a secrete key of an endorsee and a decryption algorithm implementation module. Authorized signature information is stored in the data storage stack. The information collection component collects ciphertext information and converts the ciphertext information into ciphertext information data processed by the authentication server. The authentication server transfers the ciphertext information data to the safety device, and the safety device decrypts plaintext of obtained signature information and transfers the plaintext of the signature information to the authentication server. The authentication server realizes authentication of the information medium by judging whether the plaintext of the signature information is consistent with the authorized signature information by comparison. By adopting the technology of the invention, the uniqueness and the non-imitability of the signature information are improved, thus ensuring the electronic bill to be used more safely. The system can obviously reduce the risks in using the electronic bill and promote the development of the modern financial industry.
