Embodiment Construction

[0067] figure 1 Realize the flowchart of video copyright protection method for the present invention, as figure 1 shown, including:

[0068] Step 100: Select a digital fingerprint carrier from the original video information.

[0069] This step also includes before this step: the video publisher pre-sets (generates) an anti-collusion piracy digital fingerprint database that meets performance requirements. The digital fingerprint code is bound with user information, and the digital fingerprint code has the performance of piracy tracking and conspiracy piracy tracking.

[0070] In this step, the method of selecting the digital fingerprint carrier from the original video information such as a picture may be to select the number of digital fingerprint carriers according to the digital fingerprint code length, which roughly includes: determining the bits of the fingerprint code that can be embedded in each frame of video according to the compressed format Number b, the predicted ...

Abstract

The invention provides a video copyright protection method and system as well as a video publisher entity. The method comprises the following steps: selecting a numeral fingerprint carrier from the original video information; performing copyright protection on the original video information except the numeral fingerprint carrier in an encrypting manner; at the needing moment, embedding a numeral fingerprint code into the numeral fingerprint carrier; and performing different copyright protection manners on the protected video information and then publishing to a user. In the process of embedding the numeral fingerprint code of the method, a partial video picture is confirmed as a fingerprint carrier according to the code length of the numeral fingerprint code, the number of the video picture needing the embedded fingerprint is reduced, and the video picture except the fingerprint carrier is pre-compressed, encrypted and stored in a video server. By using the method provided by the invention, the operation load of the server in the process of embedding numeral fingerprint is reduced, the unique numeral fingerprint code is embedded in each video copy, and the security of copyright protection is enhanced.

Description

technical field [0001] The invention relates to a video copyright protection technology, in particular to a video copyright protection method, system and video publisher entity based on encryption and anti-collusion piracy digital fingerprints. Background technique [0002] In recent years, the highly developed network technology has brought many conveniences to the society, but it has also caused very serious problems. Facilitated access to resources facilitates digital piracy, including illegal copying and distribution. Piracy has destroyed the value chain of digital products, damaged the interests of product manufacturers, publishers, issuers and legal users, and constituted a serious threat to the order of the network world. How to carry out copyright protection on digital products has become one of the focuses in the digital age. [0003] Traditional copyright protection technology is usually based on cryptography theory, and its protection method is to encrypt files ...
