Problems solved by technology

Along with the rapid development of the online video industry, prominent problems in video supervision are increasingly revealed: a large number of video websites lack effective review of the online video content released, unauthorized copying of videos on video websites and illegal re-release, etc. These are all detrimental to the healthy development of video as a digital medium
Existing information hiding technology still has shortcomings in terms of real-time and fidelity, so there is still a lot of room for development as a new research direction

Embodiment Construction

[0033] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0034]Embed hidden information flow such as figure 1 As shown, the specific steps are:

[0035] The first step is to construct the hidden label information after dividing the information to be hidden;

[0036] a) First generate hash value data H for the information m to be hidden;

[0037] b) Add H after m to generate synthetic information M, and divide the synthetic information M into n pieces of equal-length data, respectively M 1 , M 2 …M n , n is the number of label segments;

[0038] c) respectively in M i Then add the label i of the current label segment and the distance D between the next label and th...

Abstract

The invention discloses a method for embedding and extracting digital video information based on FLV (flash video) video structural feature in the technical field of information security, which adopts a method based on the FLV video structural feature to embed / extract hidden information to realize the real-time operation of video information hiding. The invention has high flexibility because the embedded information capacity can be determined according to the magnitude of actual hidden data as required and strong self-adaption capability because the capacity is determined by needs and can be used for anaphase arithmetic and data improvement because extensible spaces are left in a data area.

Description

technical field [0001] The invention relates to a method in the technical field of information security, in particular to a method for embedding and extracting digital video information based on FLV (FLASH VIDEO, vector video streaming media) video structure features. Background technique [0002] As a new communication medium, online video has become more and more attractive with the development of the Internet, and online video has become the source of video information that people are most interested in currently. Along with the rapid development of the online video industry, prominent problems in video supervision are increasingly revealed: a large number of video websites lack effective review of the online video content released, unauthorized copying of videos on video websites and illegal re-release, etc. All of these have damaged the healthy development of video, a digital medium. The digital hidden label technology is proposed to solve these problems. The website i...
