Information anti-counterfeiting authentication method and system

Abstract

The invention belongs to the technical field of the Internet, and provides an information anti-counterfeiting authentication method and system. The method and system are used for the anti-counterfeiting authentication of audio / video information generated on an intelligent terminal. The method comprises the steps: obtaining a description text of a source file during the generating of the source file, generating a verification code through the information of the source file, the description text of the source file and a pre-stored secret key via an irreversible encryption algorithm, and enablingthe verification code and the description text of the source file to jointly form an information identifier of the source file. During the authentication, the analysis of the information identifier passing the verification is carried out, and the description text of the source file is obtained. According to the description text of the source file, the secret key is extracted, and the extracted secret key, the source file and the analyzed description text of the source file are enabled to generate the verification code according to the same irreversible encryption algorithm. The verification code is compared with the verification code analyzed from the information identifier, and a discrimination result of the source file is generated. The method can achieve the simple and efficient anti-counterfeiting authentication, and achieves the accurate authentication of information.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an information anti-counterfeiting identification method and system. Background technique [0002] In the digital media in the Internet age, there is a large amount of information that comes from screenshots, photos, videos, screen recordings, and audio recordings of smart terminals such as mobile phones / tablets / computers, and a large amount of information has been forged by PS and other technologies, making it difficult to be true or false. In the process of online media communication and even legal procedures, it has brought a lot of trouble to people. For example, some real information cannot prove its authenticity. However, its identification requires professional, expensive and long-term procedures, and in addition to the judicial identification agencies designated by the state, other identification agencies or experts lack authority and impartiality, and the identifica...

[0002] In the digital media in the Internet age, there is a large amount of information that comes from screenshots, photos, videos, screen recordings, and audio recordings of smart terminals such as mobile phones / tablets / computers, and a large amount of information has been forged by PS and other technologies, making it difficult to be true or false. In the process of online media communication and even legal procedures, it has brought a lot of trouble to people. For example, some real information cannot prove its authenticity.

However, its identification requires professional, expensive and long-term procedures, and in addition to the judicial identification agencies designated by the state, other identification agencies or experts lack authority and impartiality, and the identification itself may also bring controversy

And some P-pictures, especially conversation records with pure background colors, such as mobile phone text messages, etc., after the post-transformation of the screenshots, it is impossible to judge by the identification of the pictures themselves
