Embodiment Construction
[0048] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0049] The present invention provides a flowchart of a preferred embodiment of an encrypted video distribution method, such as figure 1 As shown, among them, the methods include:
[0050] Step S100, the distribution server extracts the metadata in the video file in advance to generate a metadata file, and generates an original data file from the original video data after the metadata is removed from the video file, and the original data file is encrypted by an encryption algorithm to generate an encrypted original file;
[0051] Step S200, the distribution server acquires the device ID of the playback device and the user ID corresponding to the p...

The present invention discloses an encrypted video distribution method and system. The method comprises the steps that a distribution server divides a video file into a metadata file and an original data file in advance, and the original data file is encrypted to generate an encrypted original file; the distribution server acquires a device ID of a play device and a user ID of the play device, encrypts the metadata file, an encryption algorithm secret key, the user ID and the device ID and then generates an encryption meta file; the play device acquires the encryption meta file and the encryption original file, decrypts the encryption meta file, and acquires the user ID, the device ID, the encryption algorithm secret key and the metadata file; and if it is detected that the acquired device ID is identical to the ID of the device, the encryption original file is decrypted, and the decrypted video is played. Through adoption of the encrypted video distribution method and system, image clarity of the video that the user watches is ensured, further, target videos are played, the user is prevented from spreading the video randomly, and the confidentiality degree of the video is improved.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to an encrypted video distribution method and system. Background technique [0002] In the Internet age, in addition to watching TV programs on TV, people choose to watch videos online. At present, there are mainly two ways to watch videos: downloading to watch locally and watching online. These two methods have the following problems for the video distributor: [0003] 1. Once the video content is downloaded locally, it may be spread at will, which is not conducive to the protection of video copyright. [0004] 2. If the video is watched online, due to bandwidth limitations, the picture quality is far inferior to downloading it locally, and the user experience will be very poor, which will affect the viewing effect of the video. [0005] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0006] In view of the deficienc...
