Video Encryption Protects the Core Value of Online Education Institutions
With the continuous development of internet technology and the widespread adoption of computer network applications, online video has become an important means for many online education companies to enhance their teaching competitiveness. Leveraging the vast global internet market, user-friendly teaching video courses allow institutional students to enjoy the fun of learning from home while showcasing teaching quality, helping institutions stand out in the competitive online education landscape. However, due to the openness of the internet, cloud computing systems bring many benefits but also pose various security risks. Moreover, as we rapidly enter the information age, some small and medium-sized institutions have begun to blindly pursue the immediate value brought by teaching video courses, neglecting the security and confidentiality of videos and even content management systems. Once maliciously stolen, the consequences could be disastrous.
How to Ensure Video Security
To prevent video theft, educational institutions previously had two viable approaches. The first was to block the export of teaching videos to prevent leakage and stop unauthorized users from accessing video resource links. The second was to encrypt video files, with the encryption mechanism acting directly on the data itself. Even if a video is illegally obtained, as long as the encryption algorithm is not cracked, the video file cannot be played. Since the video content of online education institutions is extremely valuable—often consisting of carefully prepared lesson plans and materials by instructors—its high value attracts criminals seeking to profit from secondary distribution, making complete blocking difficult. Therefore, encrypting video storage is one of the most important technical measures to ensure video security.
POLYV Video Encryption
Generally, the most common solution for effectively protecting teaching videos is to entrust a professional video hosting service provider. Taking POLYV as an example: users can upload videos to the POLYV education cloud video platform and enable the video encryption feature (anti-download). During video transcoding, the video file is sliced into segments, and a random encryption algorithm is added to each slice, significantly increasing the cost for thieves to steal the content. Additionally, the POLYV education cloud video platform offers various innovative video security protection features, such as video watermarking (anti-screen recording) and playback domain blacklisting (anti-hotlinking).
Currently, according to feedback from online education institutions cooperating with POLYV, the number of course accesses and plays has significantly increased since using the POLYV cloud video encryption service, effectively creating a unique brand advantage. POLYV stated that it will continue to refine and upgrade video encryption based on the needs reflected by more institutions in the future.
