1. , based on the digital sealing application software of public key algorithm, it comprises 4 functional modules, and each module is made up of database file, program and webpage;

  • It is characterized in that adopting the server/browser architecture, utilize HASH function and Digital Signature Algorithm to realize effectively false proof to certificate, bill and official document etc.;

    Wherein, key generates with administration module and mainly is responsible for calculating a pair of private cipher key and public-key cryptography;

    Subject information typing and editor module mainly are responsible for the subject information of input anti-counterfeiting object in the WEB database;

    Digital sealing generates the digital sealing of mainly being responsible for calculating anti-counterfeiting object with output module;

    Digital sealing inquiry and authentication module are responsible for mainly differentiating that the anti-counterfeiting object that is printed on digital sealing is very or vacation.
