Multimedia processing method, multimedia playing method and device corresponding to method

Abstract

The invention provides a multimedia processing method, a multimedia playing method and a device corresponding to the method, and the method comprises the steps: carrying out the encryption of to-be-encrypted data in an original multimedia file through a sending end, and obtaining encrypted data, wherein the to-be-encrypted data is any part of data in the original multimedia file, a sending end sends the encrypted multimedia file and the plaintext file to a server, and the server correspondingly stores the encrypted multimedia file and the plaintext file, wherein the encrypted multimedia file comprises encrypted data and data except the to-be-encrypted data in the original multimedia file, the plaintext file comprises to-be-encrypted data in the original multimedia file. According to the method and the device, the sending end only needs to send the plaintext file and the encrypted multimedia file without sending a decryption secret key file for algorithm decryption or dividing the encrypted multimedia file into a plurality of media files for transmission, so that the operation process of playing the encrypted multimedia is simplified.

Description

technical field [0001] The present invention relates to the field of multimedia, in particular to a multimedia processing method, a multimedia playing method and a device corresponding to the method. Background technique [0002] With the development and popularization of Internet technology, multimedia files such as audio and video have become one of the main applications of the Internet, and the issue of network information security has always attracted much attention. In the prior art, in order to ensure the security of the multimedia information and prevent the leakage of the multimedia information, the multimedia is usually encrypted. A personal computer (Personal Computer, PC) platform, a webpage (Web) platform, and the like all support playback of encrypted multimedia. Among them, multimedia refers to audio and video. [0003] However, due to the low programmability of the Web platform, most solutions suitable for playing encrypted multimedia on other platforms cann...

Problems solved by technology

[0004] Restricted by the HLS protocol, multimedia files encrypted using the HLS protocol not only need to transmit the decryption key file to the Web platform to decrypt the entire multimedia file, but also need to divide the data stream in the multimedia file before transmission. The operation process Complicated, not simple and efficient enough
