Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0044] Because common video players do not have the function of playing ciphertext videos. To solve this problem, the present invention provides a ciphertext video player that can normally decrypt and play ciphertext video. see figure 1 , the first embodiment of the present invention provides a ciphertext video player, the ciphertext video playe...

Abstract

The present invention provides a ciphertext video player and a playing method. The ciphertext video player comprises a decryption module, a decoding module and a playing module. The decryption module is used for calling the video decryption algorithm in a preset video decryption dynamic link library and decrypting a ciphertext video to be played. The decoding module is used for decoding the decrypted video data after the decryption module completes decryption. The playing module is used for playing the decoded video data. According to the ciphertext video player and the playing method, the decryption and playing of an encrypted video can be realized.

Description

technical field [0001] The invention relates to the field of video processing, in particular to a ciphertext video player and a playing method. Background technique [0002] With the rapid development of video coding technology and network technology, video surveillance has become an important part of production and life. However, in an open network environment, the plaintext transmission and plaintext storage of video information are vulnerable to attacks, such as data interception, information theft, data tampering, and data addition and deletion. [0003] Aiming at this problem, some solutions already exist. For example, an authentication technology or permission division is used to prevent illegal users from accessing videos in the storage. In addition, in terms of transmission, a special safe channel is established to ensure the security of video transmission. However, there are certain defects in these methods. For example, the strict authentication process and com...
