Problems solved by technology

However, during the decryption process, due to the characteristics of the operating system, files encrypted with the same encryption algorithm will be decrypted inconsistently. For example, video file A is encrypted under operating system 1 to obtain encrypted video file B, and the encrypted video file B is stored in the operating system. The video file A can be obtained by decrypting under 1, but the encrypted video file B is decrypted under the operating system 2, and the video file A may not be decrypted, which makes it impossible for legitimate users to obtain accurate video files (legal users cannot decrypt to video file A), legitimate users cannot share the video in a timely and accurate manner, which brings inconvenience to legitimate users

Embodiment Construction

[0040] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0041] In the decryption process, due to the characteristics of the operating system, files encrypted with the same encryption algorithm will be decrypted inconsistently. The embodiment of the present invention can realize that the video file is encrypted under one operating system, and the encrypted video file can be decrypted under another operating system. Video files, so that legitimate users can share videos in a timely and accurate manner, improving efficiency.

[0042] Such as figure 1 Shown is the main method flow of video encryption in the embodiment of the present invention, including the following steps 11-12:

[0043] Step 11: Encrypt the video file to ...

Abstract

The invention discloses an encrypting method and device of a video and a decrypting method and device of the video. The encrypting method includes the steps that a video file is encrypted, an encrypted video file is formed, and encrypted feature information is obtained; the encrypted feature information is written into the encrypted video file, and the encrypted video file including the encrypted feature information is formed. According to the technical scheme, the video file can be encrypted in one operation system, the video file can be obtained through decryption in the other operation system, therefore, a legal user can accurately share a video in time, and efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video encryption method and device, and a decryption method and device. Background technique [0002] With the rapid development of mobile communication network technology, especially the wide application of mobile phones and personal digital assistants, users need to save and communicate more and more video information, which makes the security of video information more prominent. When convenience comes, people pay more and more attention to the security issue of protecting personal privacy. [0003] Currently, video files are encrypted to reduce the possibility that video information may be leaked due to illegal access, thereby improving the security of video information. However, during the decryption process, due to the characteristics of the operating system, files encrypted with the same encryption algorithm will be decrypted inconsistently. For example,...
