How to Prevent Video Piracy

With the development of internet technology, especially the widespread adoption of high-speed networks, video is becoming the primary form of online information.
86% — according to data from Cisco, a leading global internet solutions provider: in 2016, video traffic will account for 86% of total global internet traffic. Behind this massive traffic lies enormous business opportunities.
However, for the video industry, the biggest weakness is piracy. The video content painstakingly produced by creators can vanish in an instant due to massive downloads caused by piracy.
How to prevent video piracy has become the most棘手 issue facing the industry. Currently, the methods of video piracy are无非 video downloading and screen recording.Anti-Piracy Tip 1: Video Encryption (Keyframe Out-of-Order Video Content Protection System) Encrypted Video Hosting vs. Traditional DRM Systems: A Comparison in Video Encryption Against Piracy
To solve the problem of video piracy, most copyright holders adopt DRM systems. However, DRM systems are complex to develop and integrate, and are inconvenient for viewers. Not only must all viewers install DRM plugins, but authorized users often cannot open the video.
In contrast, encrypted video hosting makes preventing video piracy extremely simple. Copyright holders only need to upload the video to complete all video encryption and copyright management tasks, and viewers do not need to install any third-party software. The principle of encrypted video hosting is as follows:
Video files processed by encrypted video hosting have the following characteristics:
- Fully compatible with Flash Player; users do not need to install any third-party plugins to achieve video protection;
- Fully compatible with current HTTP video CDNs, eliminating the need to purchase expensive FMS servers;
- Due to the use of HTTP, the most mature transmission mode, the user's playback experience far exceeds that of FMS streaming protection solutions using the RTMP protocol;
- Combined with anti-leeching, it provides comprehensive protection for video files. Even if a video is hotlinked or downloaded, it cannot be played, achieving a more reliable and stringent encryption level than FMS;
- Since each video file has a unique key, even if one file is cracked, other files remain secure, significantly increasing the difficulty for crackers.
The above method only solves the encryption problem of video files. However, if pirates use screen recording, the video may still be at risk of piracy.Anti-Piracy Tip 2: Anti-Screen Recording — Educational Quiz Player
How to prevent screen recording seems like an impossible problem to solve. In fact, adopting a certain video interaction mode can effectively minimize the risk of screen recording piracy. For example, the Educational Quiz Player used in the online training industry, as shown in the figure:

Publishers can add questions during video playback. When the video reaches a specified time point, the player automatically pops up a question, requiring the viewer to answer. The viewer can only continue playing after answering the question correctly. If the answer is wrong, the video can be skipped to another specified time point. In online video teaching applications, the more interactive questions inserted, the better the anti-screen recording effect. This not only enhances learners' learning outcomes but also significantly increases the operational cost for pirates while reducing the user experience of stolen videos. Encrypted video hosting technology combined with a quiz player is currently the best method for preventing video piracy.
