A tamper-proof method for iptv video content

Abstract

The invention discloses an IPTV video content tamper-proofing method. Two function modules of signature generation and signature verification are newly added in an original process. The signature generation module is used for extracting signatures from video segment files, the signature verification module is used for conducting signature verification on received video files and deciding to permitplaying or not according to a verification result, and if video contents are illegally tampered, signature verification fails, and playing of the videos is not permitted. The novel IPTV video contenttamper-proofing method is mainly used for solving the problem that an existing IPTV video content tamper-proofing method difficultly meets the IPTV video content tamper-proofing requirement in an internet mode, the safety of IPTV video content tamper proofing is improved, the method is simple to achieve, the transformation of an existing IPTV system is smaller, and the video playing speed is alsoimproved.

Description

technical field [0001] The invention belongs to the technical field of IPTV network television, and in particular relates to an IPTV video content anti-tampering method. Background technique [0002] With the continuous advancement of the integration of the three networks and the continuous acceleration of broadband, the network mode of IPTV services is changing from private network to Internet. The Internet brings rich content and applications to IPTV services, but also brings risks in safe broadcasting. [0003] IPTV video content anti-tampering technology is an important means to prevent the risk of IPTV video broadcast security. There are two traditional IPTV video content anti-tampering methods: [0004] (1) Video encryption. This method realizes tamper-resistant video content through video encryption, which has high security. However, since video encryption and decryption rely on hardware, the flexibility is poor and the transformation of IPTV platforms and terminals...
