Problems solved by technology
[0019] - The encryption scheme for the key part of the video data needs to be decrypted according to the downloaded video file, which is not conducive to streaming playback on the mobile terminal
[0020] -The video data slicing scheme is not encrypted, so it is easy to crack
[0021] -Although the HLS encryption scheme is mature, the scheme has been made public. Just read the M3U8 index and decrypt the file to download or play

The invention provides an offline playing method and apparatus of online encrypted slice videos based on an iOS operating system. A player needs to sends a request carrying a signature to a local server to play a local offline encrypted video, and the local server only provides local offline video resources to the player only when the signature is verified to be correct. The signature is generated by calculating user information. The operation of the user information is added in a decryption algorithm used by a downloader in a decryption process, so the offline video resources cannot be normally played if the user registration information is incomplete or incorrect, thereby reinforcing the security of the local offline video resources. The scheme abides by the HLS protocol, all resources used in the protocol are cached in the local, and the local server returns the local resources to the player by HTTP response, thereby consuming no traffic. The offline playing method and apparatus of the online encrypted slice videos based on the iOS operating system provided by the invention is safer and more convenient.
Description
technical field [0001] The present invention relates to the field of encrypted video decryption at the mobile terminal and the field of multimedia technology, more specifically, to a kind of HLS (HTTP Live Streaming, which is an HTTP-based streaming media network transmission protocol proposed by Apple Inc.) encrypted transmission and decryption playback at the mobile terminal scheme. Background technique [0002] With the rapid development of mobile Internet technology and the large-scale popularization of smart phones, mobile phones are changing our lives more and more deeply, carrying various functions such as financial management, shopping, eating, entertainment, learning and living. [0003] As an important information transmission medium in people's lives, video has also emerged in large numbers with the maturity of the mobile Internet. Based on the current video copyright protection, especially the protection of video resources in educational institutions, the demand...
