A method for authenticating printed text by using a seal verification terminal

Abstract

The invention discloses a method for authenticating a sealed file through utilization of seal verification terminals. The method comprises a file sender, the seal verification terminal of the file sender, a system of a national authority organization responsible for managing seals, the seal verification terminal of a file receiver, the file receiver, a digital image file of the sealed file and a sealed file entity. Through utilization of the seal verification terminals, the method for authenticating a fact whether the sealed file is sealed and sent by the file sender or not is realized. According to the method, the problem of how to authenticate the sealed files in remote signing processes of various files is solved, whether the sealed files are true or false can be effectively distinguished, and the counterfeiting can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of document verification, and relates to a method for authenticating printed text by using a seal verification terminal. Background technique [0002] Up to now, the public security department still adopts the method of image recognition to crack down on counterfeit seals (including but not limited to official seals, contract seals, various legally effective seals, personal name seals, etc.).
