User Guide for Enhanced Protection Function of Video Courses

Function Description: After enabling risk control and uploading video materials, the video courses referenced by the video materials can only be viewed on the App. Combined with intelligent material encryption technology, it effectively prevents multi-channel course piracy. Risk prevention and control video materials can only be used in video courses and are not currently supported for other types except video courses, such as live replay, screen-recorded live broadcasts, and rich text videos.

Implementation Method:

By privately encrypting the video file, it can only be decrypted and played through the elink player on the App, effectively preventing course piracy caused by the leakage of video links.

Terminal Restrictions:

Since the front-end code of web pages and Mini Programs is relatively easy to be decompiled, effective private encrypted playback cannot be achieved on web pages and Mini Programs. Therefore, enhanced protection restricts the playback terminals. Currently, only the "elink Student Edition App" can be used for playback. Even if other terminals enter the relevant course page, only a screen guiding users to watch on the "elink Student Edition App" will be displayed, effectively preventing illegal elements from pirating courses through other terminals.

Function Restrictions:

Since enhanced protection encrypts the playback link itself, it protects against illegal elements obtaining the original video playback link and directly pirating courses (the main piracy path currently discovered). Screen recording prevention on the App can be enabled on the B-side. However, if illegal elements record the screen through other physical means (including but not limited to physical screen recording with a camera, physical screen recording with a video capture card, and recording the PC screen by installing an emulator on the PC), enhanced protection alone cannot provide protection. To combat such course piracy, it is recommended to enable the marquee and watermark functions, trace the source of piracy, and resort to legal means to protect relevant rights and interests.
