Problems solved by technology

[0018] Usually, digital file producers apply for trusted time stamps from traditional trusted time stamp servers to prove the generation time of digital files, but cannot prove the identity of digital file creators
In order to prove the identity of the digital file producer, it is necessary to apply for a digital certificate from the digital certificate center CA, and have to pay a higher fee

Embodiment Construction

[0061] Through the technical solution of the invention, the user can confirm whether the information stored in the digital file comes from a real digital file maker, and whether the information has been tampered with by a third party. The concrete implementation scheme of scheme is as follows:

[0062] (1) The digital file producer generates a digital summary (HASH value) based on the original information of the digital file and the identity information in the digital file, and applies to the Trusted Identity Timestamp Service Center, and the Trusted Identity Timestamp Service Center verifies the digital file After the creator's identity is signed, a trusted identity timestamp is generated based on the digital abstract, verified identity information, and accurate date / time from an authoritative time source;

[0063] (2) The digital file generation module generates a trusted digital file according to the original information of the digital file and the time stamp of the trusted...

Abstract

The invention discloses an anti-counterfeit method and system for a digital file. The invention comprises that a digital file producer generates a digital summary according to the content of a digital file, applies for a trusted identity timestamp from a trusted identity timestamp server, and generates a trusted digital file according to original information of the digital file and the trusted identity timestamp; and when the digital file is required for use or verification, the effectiveness and integrity of the generation time and content of the digital file are ensured, as well as the identity authenticity of the digital file producer by verifying the trusted identity timestamp in the digital file.

Description

technical field [0001] The invention relates to the fields of cryptography, product anti-counterfeiting, food and medicine, and computer network security. Specifically, the invention provides an anti-counterfeiting method and system for digital files. Background technique [0002] PKI (Public Key Infrastructure), or "Public Key Infrastructure", is a key management platform that follows established standards. It can provide cryptographic services such as encryption and digital signatures and the necessary key and certificate management systems for all network applications. Generally speaking, PKI is the infrastructure for providing security services established by using public key theory and technology. PKI technology is the core of information security technology, and also the key and basic technology of e-commerce. [0003] PKI technology uses certificates to manage public keys, and through a third-party trusted organization—CA (Certificate Authority) certification center,...
