Method for distributing and encrypting streaming media

Abstract

The present invention provides a method for distributing and encrypting streaming media, characterized in that: first a DRM encryption is performed on a movie which can be played or downloaded, then a distribution is performed by P2P technology, the movie only can be normally watched when an effective certificate is obtained during the playing, so that the problems of slow play speed, slow download speed and pirate can be solved at the same time. The specific work flow of the method comprises the following steps: (1)a digital program authorization center is established; (2)a digital program is encrypted by using a secret key, and the encrypted information is stored into the head of the digital program; (3)an authentication of the digital program authorization center and a decoding of the secret key are needed to be obtained when the program is requested; (4)users play the digital program by the decoding of the secret key; (5)the downloaded digital program can not be played without the authentication authorization; and (6)users can share the download by means of P2P, or perform a download on the P2P server. The benefits of the present invention is that: the method can ensure application and popularization of the streaming media, effectively solve the copyright protection problem of the video downloads, and has an active effect on protection of media industry.

Description

【Technical field】 [0001] The invention relates to the field of computer information technology, in particular to a streaming media distribution and encryption method, which can effectively solve the problems of arbitrary downloading and piracy of digital programs. 【Background technique】 [0002] Computer information technology is one of the fastest developing technologies since the 20th century, and it is also the fastest and most applied technology, which has made great contributions to the era of knowledge economy. [0003] In computer information technology, P2S technology is a server-side download technology, which can be divided into HTTP (Hyper Text Transportation Protocol, translated as: Hypertext Transfer Protocol) and FTP (File Tran-sportation Protocol, translated as: file Transfer Protocol) two types, which are the way data is exchanged between computers, and are the two most commonly used download methods. The principle of the P2S download method is very simple, ...

AI Technical Summary

Problems solved by technology

[0006] Although the P2S download method can realize multi-thread download, because the download resources come from a single server, the download speed will be affected and become very slow when there are too many downloaders, and the server may crash as the load increases. Once the server crashes, the P2S download method will not continue

[0007] In the P2P method, the more people download, the faster the download speed will be, so that Internet users can download quickly. If you want to serve others as a seed, the download speed will drop sharply. If you can’t find the seed, you can’t continue downloading
