Embodiment Construction

[0017] Hereinafter, the present invention will be explained in detail based on a preferred embodiment shown in the drawings, but the present invention is not limited to this embodiment.

[0018] Such as figure 1 The steps shown are as follows:

[0019] 1. Slice the source video, and set the length of slicing according to your needs;

[0020] 2. For each slice, use the agreed random code to mark the file header byte; the agreed random code is: a bytecode randomly generated during encryption with a length greater than 10 and less than 255 numbers written into the slice header, set the first One value is the length of the random code, and the second value is the position value of the agreed encryption algorithm code in the random code. For example, the random code is 11, 5, 3, 6, 45, 9, 66, 2, 1, 4, 78, it means that the random code occupies 11 bytes, and the sixth byte value 9 (starting from 0) is the encryption algorithm code.

[0021] 3. Encrypt each slice according to the ...

Abstract

The invention provides a video segment encryption and playing method based on random encryption. The method comprises performing video segment processing, appointing a random code for a segment header sign, and performing byte encryption processing according to the random code appointment, and decrypting and playing the video segment according to a random code algorithm by use of the authorization of a dedicated player. The decrypting and playing can be performed without the supporting of a server when the algorithm is used for decrypting and playing, so that the method can be extensively applied to various playing environments.

Description

technical field [0001] The invention relates to the field of video encryption, in particular to a method for encrypting and playing video slices based on random encryption. Background technique [0002] With the development of Internet technology, multimedia resources such as video and audio have been widely used in various application systems such as entertainment, learning, and office. However, due to the openness of the Internet, the protection of video resources with intellectual property rights from being stolen has become particularly important. Traditional video encryption algorithms are difficult to meet the requirements of playing protected video resources on different platforms and in different environments. Therefore, a video encryption algorithm that can adapt to various playback environments is needed to encrypt and protect videos. Contents of the invention [0003] The invention provides a method for encrypting and playing video slices, which is used to solv...
