After a channel A is created for a client A, authorizing media resource resources for the channel A, and when the media resource resources are authorized for the channel A, a media resource processing system uses a media resource encryption and decryption module in an operation management background to carry out encryption processing to obtain a media resource encryption identifier; the specific process is as follows: encrypting the channel identifier and the media asset identifier by using a preset symmetric encryption algorithm to obtain a first encryption character string, wherein the first encryption character string is represented by aaa; processing the channel identifier, the media asset identifier and the channel encryption factor by using a Hash algorithm to obtain a second encryption character string, wherein the second encryption character string is represented by xxxxxx; media asset encryption identifier aaa.xxxxx; it should be noted that "-" is used as a separator between the first encrypted string and the second encrypted string, and further, the separator may also be "/", which is not limited herein.
After authorizing the media asset resources for the channel a, sending information of the authorized media asset resources to the client a through a media list interface of the channel server, so that the client a can display the related media asset resource information to the user.
After the client a displays information of the asset resources to the user, the user selects the asset resources, at this time, the client a needs to generate an asset playing request, the asset playing request may also be referred to as a playing string getting request, and the channel SDK requests to play an http request of the server, specifically, the asset playing request includes a channel identifier, an asset encryption identifier, a random number, a client timestamp, a signature mode, and a first signature value, and further, when the client generates the first signature value, the channel identifier, the asset encryption identifier, the random number, the client timestamp, and a channel factor are processed in a signature mode, so as to obtain the first signature value, preferably, the signature mode is sha 256.
After receiving the media asset playing request, the playing request end performs signature verification on the media asset playing request, and specifically includes: analyzing the media asset playing request to obtain a channel identifier, a media asset encryption identifier, a random number, a client timestamp, a signature mode and a first signature value in the media asset playing request; the channel factor can be obtained based on the channel identifier, and the channel identifier, the asset encryption identifier, the random number, the client timestamp and the channel factor are processed in a signature mode, so that a second signature value is obtained, wherein the signature mode is the same as the signature mode used by the client A. And when the first signature value is the same as the second signature value, determining that the media asset playing request passes signature verification, and sending the channel identifier and the media asset encryption identifier to an operation management background.
The operation management background uses the media asset encryption and decryption module to decrypt the media asset encryption identifier, which specifically includes: decrypting the first encryption character string in the media asset encryption identifier by using a preset inverse algorithm of a symmetric encryption algorithm to obtain a channel identifier and a media asset identifier; determining a corresponding channel encryption factor based on the obtained channel identifier, processing the obtained channel identifier, the media asset identifier and the channel encryption factor by using a Hash algorithm to obtain a third encryption character string, determining the obtained media asset identifier as a media asset request identifier when the third encryption character string is the same as a second encryption character string in the media asset encryption identifier, and performing authentication processing on the media asset request identifier by using an authentication module, wherein the specific process comprises the following steps: judging whether the media asset request identification exists in a media asset list of a media asset channel of the client A, and sending the media asset request identification to a playing server when the media asset request identification exists in the media asset list; and when determining that the media asset request does not exist in the media asset list, sending a request failure identifier to the playing service terminal.
After receiving a media resource request identifier fed back by an operation management background, a playing server determines a resource address corresponding to the media resource request identifier and sends the resource address to a client A, so that the client A acquires media resource through the resource address and displays the acquired media resource; when receiving the request failure identifier, the playing server feeds back preset request failure information to the client A, so that the client A displays the request failure information to the user.
