Information anti-counterfeiting identification method and system

Abstract

The invention belongs to the technical field of the Internet, and provides an information anti-counterfeit identification method and system, which are applied to the anti-counterfeit identification of information files such as audio-visual images generated on intelligent terminals. The method includes obtaining the description text of the source file while generating the source file, generating a verification code through an irreversible encryption algorithm through the source file information, the description text of the source file and a pre-stored key, and combining the verification code with the The descriptive text of the source file together constitutes the information identifier of the source file. During authentication, analyze the information identifier that passed the inspection, obtain the description text of the source file, retrieve the key according to the description text of the source file, and combine the retrieved key with the source file and the description text of the parsed source file According to the same irreversible encryption algorithm, the check code is generated, compared with the check code parsed from the information identifier, and the identification result of the source file is generated, which can perform anti-counterfeiting identification simply and efficiently, and accurately determine the authenticity of the 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
