Double-two-dimensional product anti-counterfeiting scheme based on PKI (Public Key Infrastructure)

Abstract

The invention provides a double-two-dimensional product anti-counterfeiting scheme based on PKI (Public Key Infrastructure). A product manufacturer respectively prints one or more credible two-dimensional codes at the outer side of a product package (named as visible two-dimensional codes), and prints one or more credible two-dimensional codes or ordinary two-dimensional codes at the inner side of the product package simultaneously, or tightly covers the printed two-dimensional codes by using other non-transparent media (named as hidden two-dimensional codes). A user can verify the visible two-dimensional codes through a two-dimensional code verification module, so as to primarily determine whether the product to be true or false. The scheme provided by the invention provides a method for simply, conveniently and rapidly judging the truth of the product. Shown by a picture, the scheme at least consists of a product source tracing center module, a CA (Certificate Authority) module, a two-dimensional code generation module and the two-dimensional code verification module.

Description

technical field [0001] The present invention relates to the fields of cryptography, product anti-counterfeiting, and food and drug safety. Specifically, the present invention provides a PKI (Public Key Infrastructure: public key infrastructure)-based anti-counterfeiting scheme for dual-dimensional code products. Background technique [0002] PKI is a new security technology, which is composed of basic components such as public key cryptography, digital certificate (Certificate), CA. PKI public key infrastructure is a system or platform that provides public key encryption and digital signature services for the purpose of managing keys and certificates. An organization can establish a secure network environment by adopting the PKI framework to manage keys and certificates. PKI mainly includes four parts: certificate in X.509 format and certificate revocation list CRL; CA operation agreement; CA management agreement; CA policy formulation. A typical, complete and effective PK...

This conversion is a compressed mapping, that is, the space of the hash value is usually much smaller than the space of the input. Different inputs may generate the same output, but it is impossible to uniquely determine the input value from the hash value.
