Abstract

The invention discloses an IPTV (Internet Protocol Television) digital rights management (DRM) method and device based on digital watermarking and encryption, wherein the method comprises the following steps that: an IPTV system server side inserts copyright watermarking into a digital video content, encrypts the digital video containing the copyright watermarking, and sends the encrypted digital video containing the copyright watermarking to an IPTV terminal; the IPTV terminal decrypts the received digital video data, to obtain the digital video content containing the copyright watermarking; and the copyright watermarking is extracted / detected from the digital video content, whether the video program is legal is confirmed according to the copyright watermarking, if yes, the video program is allowed to be played at the IPTV terminal.

Description

technical field [0001] The present invention relates to the field of IPTV, in particular to an IPTV digital copyright management method and device based on digital watermarking and encryption. Background technique [0002] Digital Rights Management (DRM, Digital Rights Management) is a series of hardware and software technologies to protect digital content. Its main purpose is to protect digital content, so that buyers of digital content can use it within the specified scope of authorization. At present, in the method of implementing IPTV digital rights management by using cryptographic technology, the security of transmission and distribution of digital content is protected, and most of them use encryption and decryption technology with high cost as the technical means of IPTV digital content protection. [0003] However, the IPTV front-end system performs a large number of calculations on the encryption of digital video content and the decryption of user terminals, which ...
