Abstract

The invention discloses an identifying method and system of digital signature and seal. According to the invention, a signature terminal and a signature server are interacted and signature character string information is generated according to attribute information of a signature file; the signature character string information is generated according to the attribute information of the signature file so that a signature is not easy to counterfeit; when the signature and seal information is identified, the attribute information of the signature file corresponding to a signature character string is generated according to the signature character string information in the signature file and interaction between the signature server and an identifying client, so that the signature file can be identified and the accuracy and the safety of identification are guaranteed.

Description

technical field [0001] The invention relates to the technical field of digital signature seals, in particular to an identification method and system for digital signatures and seals. Background technique [0002] Seals are generally used to sign important documents such as contracts and agreements, so the anti-counterfeiting of seals has always been valued by people. For a long time, anti-counterfeiting experts racked their brains and came up with various anti-counterfeiting methods for seals, such as making textured seals, coded seals, QR code seals, chip seals, etc. Among them, the stamp of the coded seal contains mostly anti-counterfeiting codes, and the source of the seal can be found through the Internet or telephone; the chip seal is embedded with a smart chip at the end of the seal, and the smart chip contains the attribute information of the seal, such as holding With the information of the seal unit, etc., the card reader can obtain the real information of the seal...
