Official seal fake detection method and device based on network digital certificate and network lookup

Abstract

The invention discloses an official seal fake detection method and device based on a network digital certificate and network lookup. The device comprises an official seal printer connected with an official seal fake detection system. A central processing unit MCU in the official seal printer is connected with a communication assembly, a displayer, a printing assembly, a storage and a USB interface. A power module supplies power to the official seal printer. The official seal fake detection method comprises the steps that the official seal fake detection system is built for user inspection, the digital certificate is issued when a user passes identity authentication, the official seal printer prompts selection of official seal types, a USB intelligent card is plugged into the USB interface of the official seal printer, copies needing to be stamped, the user name and a password are input, the identity and validity of the digital certificate are verified, fake detection codes are generated in the official seal fake detection system randomly, the official seal printer displays an official seal pattern, the user selects the position of a two-dimension code, and the official seal printer prints an official seal. By means of the method, whether the official seal is true or false can be queried whenever and wherever, the official seal can be verified and queried whenever and wherever through mobile phone APPs, and hazards caused when false official seals or copied official seals are used are completely eradicated.

Problems solved by technology

[0014] The common problem in the contents disclosed in the above four patent documents is that the official seal printer cannot be used independently from the computer, which limits the use of the official seal printer to a large extent.

Individual inventions also provide methods for checking the authenticity of official seals, but it is very cumbersome to conduct anti-counterfeiting inquiries relying on text, graphics, etc., and the practicability is not strong. At the same time, various anti-counterfeiting marks and anti-counterfeiting codes can be PS into other documents by scanning and taking pictures. Go, even if the official seal information can be found to be true, it is difficult to guarantee that the official seal is not counterfeited
