Multimedia data processing method, apparatus, system, and storage medium

An apparatus for processing multimedia data, the apparatus comprising:

• a memory storing instructions;
• and
• a processor in communication with the memory, wherein the processor, when executing the instructions, is configured to cause the apparatus to:
• receive a playing request from a remote terminal, the playing request carrying an identifier of multimedia data,
• generate a verification parameter according to the playing request using a preset conversion algorithm, wherein:
• the verification parameter is for single-use, and
• the verification parameter is valid within a preset validity period and is invalid outside the preset validity period,
• obtain a link address of the multimedia data according to the identifier of the multimedia data,
• generate a playing address according to the verification parameter and the link address, and
• send the playing address to the remote terminal;
• receive a request for multimedia data carrying the playing address;
• extract the verification parameter and the link address from the playing address carried in the request for multimedia data;
• determine whether the verification parameter is valid;
• when it is determined that the verification parameter is valid, obtain the multimedia data according to the link address for delivery to the remote terminal;
• when it is determined that the verification parameter is invalid, reject the request for multimedia data;
• and
• deliver the multimedia data according to the playing address to the remote terminal for playing the multimedia data,
• wherein, when the processor is configured to cause the apparatus to determine whether the verification parameter is valid, the processor is configured to cause the apparatus to:
• determine whether the preset validity period of the verification parameter expires and whether the verification parameter has been previously used;
• when it is determined that the preset validity period of the verification parameter expires or the verification parameter has been previously used, determine that the verification parameter is invalid;
• and
• when it is determined that the preset validity period of the verification parameter does not expire and the verification parameter has not been previously used, determine that the verification parameter is valid.

A non-transitory computer readable storage medium storing instructions, the instructions, when executed by a processor, cause the processor to perform:

• receiving a playing request from a remote terminal, the playing request carrying an identifier of multimedia data;
• generating a verification parameter according to the playing request using a preset conversion algorithm, wherein:
• the verification parameter is for single-use, and
• the verification parameter is valid within a preset validity period and is invalid outside the preset validity period;
• obtaining a link address of the multimedia data according to the identifier of the multimedia data;
• generating a playing address according to the verification parameter and the link address;
• sending the playing address to the remote terminal;
• receiving a request for multimedia data carrying the playing address;
• extracting the verification parameter and the link address from the playing address carried in the request for multimedia data;
• determining whether the verification parameter is valid;
• when it is determined that the verification parameter is valid, obtaining the multimedia data according to the link address for delivery to the remote terminal;
• when it is determined that the verification parameter is invalid, rejecting the request for multimedia data;
• and
• delivering the multimedia data according to the playing address to the remote terminal for playing the multimedia data,
• wherein the determining whether the verification parameter is valid comprises:
• determining whether the preset validity period of the verification parameter expires and whether the verification parameter has been previously used;
• when it is determined that the preset validity period of the verification parameter expires or the verification parameter has been previously used, determining that the verification parameter is invalid;
• and
• when it is determined that the preset validity period of the verification parameter does not expire and the verification parameter has not been previously used, determining that the verification parameter is valid.
