Embodiment Construction

[0032] The technical solution will be further explained below in conjunction with the accompanying drawings and embodiments.

[0033] The real-time digital video watermarking method based on the H.264 standard described in this technical solution, its overall flow chart is as attached figure 1 As shown, according to the technical solution, the process implemented in one embodiment is as follows:

[0034] Embedding steps:

[0035](1) Watermark preprocessing, including obtaining the binary code of the watermark and using chaotic encryption or other encryption algorithms to encrypt the watermark binary code. In the embodiment, the watermark information we selected is the Chinese text "video watermark", and it is converted into a binary code , and then use the chaotic encryption algorithm to encrypt the watermark information to be embedded to obtain the binary watermark information.

Abstract

The technical scheme provides a real-time digital video watermarking method based on an H.264 standard, comprising the following steps of: embedding watermarking information obtained after processing and coding and used as secondary enhancing information into a secondary enhancing information (SEI) field of each frame by analyzing the H.264 protocol standard and using available information resources in the H.264 standard; and ensuring robustness and nonvisibility of watermarking on the condition that video quality and a code stream format are not influenced. The real-time digital video watermarking method based on the H.264 standard can effectively resist frame deletion attack, has a simple realization mode, is used for solving various problems in the prior art that spatial synchronous distortion and photometric distortion can not be effectively resisted. The technical scheme can be used for judging copyright ownership or hiding, secretly carrying and transmitting information, and the like.

Description

technical field [0001] The invention relates to a digital video watermarking method, in particular to a digital video watermarking method based on the H.264 standard, and belongs to the field of digital video processing. Background technique [0002] With the popularization of network communication, many traditional media contents have been transformed into digital, and will soon occupy a huge market share in e-commerce, such as online sales of mp3, vigorous promotion of digital theaters, sales of online pictures, e-books, etc., in wireless With the evolution of mobile networks from the second generation to the third generation, mobile users will be able to access digital media content on the Internet conveniently and quickly, and the application of digital media content based on wired or wireless networks will soon become a new tradition in the information age. However, the security of digital media content has become a bottleneck problem, restricting the progress of many c...
