Problems solved by technology

Due to the extremely simple copying of these digital video works, and almost no signal loss in the process of unlimited copying to achieve almost perfect picture quality, this has led to a very serious problem of piracy. At present, there are mainly two problems: first, digital Video works are illegally intercepted during transmission; Second, illegal redistribution of digital video works
Although the system can be used to automatically clean up illegally uploaded videos, the filtering sys

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 As shown, the system of the present invention includes a fingerprint library management module 100 , a work selling module 200 and an anti-piracy filtering module 300 . Each part is described in further detail below.

[0025] The fingerprint library management module 100 is used for unified management of the digital fingerprints embedded in the digital video works, specifically to record the embedded fingerprints allocated by the works selling module 200 and issue fingerprint certificates, and upload the fingerprints to the anti-piracy filtering module 300. Correlation detection of fingerprints for digital video works. In order to protect the copyright owner's copyright of digital video works, the fingerprint library management module 100 must be managed uniformly. The fingerprint library management module 1...

Abstract

The invention relates to an anti-piracy filtering system for use in the transmission of digital video works. In the system, the fingerprint of a publisher is embedded into the digital video works in a digital fingerprint mode and the digital fingerprint is extracted when the publisher or a consumer uploads the digital video works onto a video sharing website, so that the filtration of the video works is realized by combining a digital fingerprint certificate verification mode and the aim of preventing illegal copying and uploading is fulfilled. The anti-piracy filtering system for use in the transmission of the digital video works has the characteristic that a digital fingerprint extraction module is applied to a process of uploading of a customer at a client for stopping the uploading of pirates when the pirates are detected, so that the active protection of digital copyright is realized. The anti-piracy filtering system for use in the transmission of the digital video works covers a wide range and a large area, has low economic cost due to the distribution of cost into the video uploading processes of each customer, and has a considerable prospect.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to an anti-piracy filtering system in uploading digital video works. Background technique [0002] Digital video is currently the most widely used form of multimedia. The use of digital video compression can reduce the burden of digital video storage and transmission, and enable digital video to achieve fast transmission and real-time processing. With the development of network technology, the transmission speed of digital video on the Internet is also getting faster and faster. At the same time, network video It is becoming more and more popular, and the uploading of digital video works is becoming more and more frequent. [0003] For commercial digital video works, the general business process is as follows: copyright owners distribute digital video works to distributors to obtain benefits, and distributors obtain benefits by uploading video works to vide...
