Problems solved by technology

For the means of registration number query or online database retrieval, the main problems are: the cost of establishing and maintaining a huge network database system is high, the verification efficiency is low, the dependence on infrastructure and regional environment is large, and the timeliness of multi-party collaborative work is large , It is inconvenient to implement verification in a mobile environment (such as on an airplane), and the security of database technology a

Embodiment approach

[0117] In this anti-counterfeiting system, the technical equipment and method standards for certification and verification are disclosed (for engineering implementation and popularization and application), and the equipment used can also be publicly purchased from merchants (helping to reduce costs and improve cost performance). The owner authorizes the certificate maker to secretly use the encryption key set, so the encryption key is also called the certificate production key. At the same time, the owner authorizes the verifier to use the decryption key set, so the decryption key is also called the verification key. In principle, neither the certificate maker nor the verifier can master the two keys of certificate making and verification at the same time, so as to prevent the technical approach of "self-stealing". There are two implementations for granting a verifier a decryption key: Main scheme: The owner sends the decryption key K of the digital subchapter v1 , the decr...

Abstract

This invention is a kind of soft certification false proof method that based on graphic code primary and secondary seal family information association mechanism. The primary and secondary seal family of the certification embeds the knowledge-type privacy character information of certification holder. There is some logic constrained relation between the primary and secondary seal information, and can stop the counterfeit and fraud. The non-simulation capability of this certification is decided by the logic result of key and knowledge character information of certification holder, and doesn't relate to the technique and equipment. So the technical regulation can be an open system. This invention also replaces the high-cost physical equipment process complexity method with the low-cost logic calculus complexity method. And replaces the human sense identifying and other technical method with the electronic information processing method.

Description

technical field [0001] The invention relates to certificate anti-counterfeiting technology, in particular to a method for protecting the content information of soft certificates with legal holders and the anti-counterfeiting method of the holder's characteristic information and its realization technology, which belongs to the field of electronic information technology (computer technology). Background technique [0002] 1. Significance and characteristics of soft document anti-counterfeiting: [0003] Documents (certificates) refer to all printed texts that carry information that are protected by law and have the effect of proof. Modern society is inseparable from certificate information, and certificates are divided into two types: soft and hard. The use of soft certificates is more widely at present, such as: passports, driver's licenses, property rights certificates, certificates of merit, honorary certificates, qualification certificates, practice certificates, access p...
