Method and device for preventing hotlinking of streaming media files

Abstract

An embodiment of the present invention discloses an anti-stealing-link method and device for a stream media file. The method includes: after obtaining a URL of the stream media file from middleware, a terminal sends an index file request message to a media server according to the URL and receives a target file returned by the media server in response to the index file request message, wherein the target file is obtained by analyzing the target file generated after encrypting the index file by the media server according to the target secret key, and the target secret key is obtained by analyzing a character string included in the abovementioned URL by the media server according to an encryption algorithm and an encryption secret key agreed with the middleware, and finally, the terminal analyzes the target file according to the target secret key to obtain the index file and obtain a fragmentation file of the stream media file from the media server based on the index file. The implementation of the present invention embodiment increases the anti-stealing-link reliability and accuracy of the stream media file.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for preventing hotlinking of streaming media files. Background technique [0002] With the rapid development of Internet technology and multimedia technology, authorized users can access streaming media files provided by multimedia service providers through media servers through terminals (such as mobile phones, notebooks, etc.), such as video files, etc. However, in practical applications, some Unscrupulous merchants can steal the URL (Uniform Resource Locator, Uniform Resource Locator) of the streaming media file provided by the multimedia service provider through related technologies (such as packet capture technology), and use the stolen URL to make other users (multimedia service providers) Unauthorized users) access the streaming media files provided by the multimedia service provider to illegally obtain benefits, which damages the legitimate intere...

[0002] With the rapid development of Internet technology and multimedia technology, authorized users can access streaming media files provided by multimedia service providers through media servers through terminals (such as mobile phones, notebooks, etc.), such as video files, etc. However, in practical applications, some Unscrupulous merchants can steal the URL (Uniform Resource Locator, Uniform Resource Locator) of the streaming media file provided by the multimedia service provider through related technologies (such as packet capture technology), and use the stolen URL to make other users (multimedia service providers) Unauthorized users) access the streaming media files provided by the multimedia service provider to illegally obtain benefits, which damages the legitimate interests of the multimedia service provider. Therefore, for multimedia service providers, the anti-leeching of streaming media files appears to be especially important

[0003] In the prior art, anti-hotlinking technologies for streaming media files mainly include two types: one is to add a time stamp to the URL to set the validity period of the URL. This method enables authorized users to access streaming media files within the validity period. The user requests a new URL through the terminal, but this method cannot prevent the merchant from stealing the URL within the valid period of the URL through related technologies; the second is through IP authentication, that is, when the user requests the index file of the streaming media file through the URL, the media server compares Whether the IP address of the user is consistent with the IP address in the authentication anti-leech link generated by the media server, if consistent, it shows that the URL has not been stolen (that is, the user is an authorized user), if inconsistent, it shows that the URL is stolen (that is, the The user is an unauthorized user), but this method cannot prevent unscrupulous merchants from forging the same IP address as the authorized user to pass the IP authentication of the media server, and when the IP address of the authorized user changes, the authorized user cannot access the IP address in the media server. streaming files

[0004] Therefore, the anti-leech technology of streaming media files in the prior art has the following problems: the reliability of anti-leech is low and the accuracy is poor
