Abstract

The invention provides the method and system of a kind of HLS Streaming Media DRM, the method comprise the steps that media processing server, for data content being carried out copyrights of data encipherment protection process；Client player, by integrated SDK, is connected with data encryption processing server by SDK, is decrypted with the decipherment algorithm mated with AES, decodes, plays.When video flowing is cut into slices by streaming media server, it is transmitted encryption.Transmission encryption refers to be encrypted the content of media resource in transmitting procedure, needs special algorithm content to be deciphered.

Description

A kind of method of HLS Streaming Media DRM
Technical field
The present invention relates to Internet technical field, specifically, particularly relate to a kind of under internet environment, HLS is flowed matchmaker Body uses a kind of digital copyright protecting (DRM) system to prevent the method for designing stolen.
Background technology
Along with the fast development of information-intensive society, audio/video flow propagation in the Internet media is more and more universal, and individual is not Only can obtain audio-video frequency content from much information passage quickly and easily, also have its large-scale illegal, biography simultaneously The ability pass, sold.This is the behavior of Streaming Media manufacturer interests and video copy of constituting a serious infringement, it is desirable to have a kind of efficient system Take precautions against, hit it.
Digital copyright protection technology be audio frequency and video are produced in information network, transmit, conclude the business, use during each side power The total solution that profit carries out clear and definite definition, distinguishes, concludes the business, protects, monitors and follow the tracks of.The generally sound of DRM technology protection Video, is after encrypted copyright, generates the effective certificate of authority, is published to user terminal by the Internet, in client pair Shielded content, after authorization identifying, uses terminal unit to play out viewing.
In tradition DRM workflow, after user buys digital content product, it is difficult to control it and is no longer replicated and expands Dissipating, because being directly bound of user and digital content product cannot really be realized, non-purchase person can also be according to the use of buyer Family information uses its digital content product bought.It would therefore be desirable to find a kind of binding relationship by user profile and numeral Content product is directly bound.
In common DRM method, the encryption of streaming media data is static, and disposably, stream medium data is by thing First encrypt, pack, deposit on the server, do not ensure that Streaming Media copyright protection safety after transmission, broadcasting and broadcasting Property.Meanwhile, the encryption of audio frequency and video is conciliate secret meeting and is consumed substantial amounts of time and server resource, inefficient.
On the basis of present invention copyright protection standards and norms at home and abroad, develop a kind of in video flowing transmitting procedure The middle antitheft access method adding encryption word string, it is achieved the copyright protection to digital content, supports that the content under internet environment is divided Send out.
Summary of the invention
It is an object of the invention to overcome the problems referred to above, thus propose a kind of addition in HLS video flowing transmitting procedure The antitheft access method of encryption word string, steals purpose reaching anti-.
The method of the HLS Streaming Media DRM of the present invention, including: Streaming Media processing server, for data content number Process according to encrypted copyright protection；Client player, by integrated SDK, is connected with data encryption processing server by SDK, with It is decrypted with the decipherment algorithm of AES coupling, decodes, plays.When video flowing is cut into slices by streaming media server, enter Row transmission encryption.Transmission encryption refers to be encrypted the content of media resource in transmitting procedure, needs special algorithm ability Content is deciphered.
The method for designing of the method for the HLS Streaming Media DRM of the present invention is as follows, comprises the following steps:
Step 1. streaming media server starts to carry out video flowing HLS section, and section file is with the name of section time, for side Just understand, simplify and be exemplified as 001.ts, 002.ts ..., the rest may be inferred；
Step 2. streaming media server adds encryption word string to section.Support three kinds of AESs at present, can combine and make With, generally only application one in every kind of AES.One is section file encryption, including two kinds of AESs, permissible Prevent pc end flash from stealing chain.Two is section packet encryption, i.e. ts packet privatization is possible to prevent mobile phone terminal, and ios equipment is stolen Chain.
Section is published to user side by step 3. streaming media server；
Step 4. user side uses special player to be decrypted with the decipherment algorithm mated with AES, decode, broadcast Put.
Above-mentioned streaming media server is with special algorithm encryption word string and joins in section file, except special broadcasting Device, video data cannot be decoded by other system, even if by unauthorized download, download side also cannot decipher or play.Separately Outward, streaming media server, not to whole file encryption, has only encrypted interpolation word string, decrease encryption, decrypting process consume Time and server resource.
Detailed description of the invention
Hereinafter embodiments of the present invention will be explained in detail.It is to be understood that embodiment described herein is only used for solving Release the explanation present invention, be not intended to limit the present invention.
The method and system of the HLS Streaming Media DRM of the present invention, including: Streaming Media processing server, for data content Carry out copyrights of data encipherment protection process；Client player, by integrated SDK, by SDK with data encryption processing server even Connect, be decrypted with the decipherment algorithm mated with AES, decode, play.At streaming media server, video flowing is cut into slices Time, it is transmitted encryption.Transmission encryption refers to be encrypted the content of media resource in transmitting procedure, needs special algorithm Content could be deciphered.
The method for designing of the method for the HLS Streaming Media DRM of the present invention is as follows, comprises the following steps:
Step 1. streaming media server starts to carry out video flowing HLS section, and section file is with the name of section time, for side Just understand, simplify and be exemplified as 001.ts, 002.ts ..., the rest may be inferred；
Step 2. streaming media server adds encryption word string to section.Support three kinds of AESs at present, can combine and make With, generally only application one in every kind of AES.One is section file encryption, including two kinds of AESs, permissible Prevent pc end flash from stealing chain.Two is section packet encryption, i.e. ts packet privatization is possible to prevent mobile phone terminal, and ios equipment is stolen Chain.
Section is published to user side by step 3. streaming media server；
Step 4. user side uses special player to be decrypted with the decipherment algorithm mated with AES, decode, broadcast Put；
Above-mentioned streaming media server is with special algorithm encryption word string and joins in section file, except special broadcasting Device, video data cannot be decoded by other system, even if by unauthorized download, download side also cannot decipher or play.Separately Outward, streaming media server, not to whole file encryption, has only encrypted interpolation word string, decrease encryption, decrypting process consume Time and server resource.
