How to prevent screen recording and downloading of online education course videos

1.AI video invisible traceability watermark

This function can hide watermarks in videos, which will not affect the viewing experience, but can help companies protect video copyright well. More importantly, for stolen infringing content, this function can be used to trace the source and track the infringement.

2.VRM fragmented out-of-order video encryption

Distributed coding technology is used to physically slice video files, and each video is encrypted with a mixture of multiple algorithms. At the same time, combined with an independently developed codebook, the key data is mixed out of order, and the video files are encrypted at the highest level. In this way, the encrypted Even if the video content is downloaded, it cannot be redistributed maliciously, making it twice as difficult to crack the video.

3.Html5 full-link video encryption

The common H5 encryption on the market adopts the standard Apple HLS Encryption video protection mechanism. On this basis, we carry out in-depth optimization, deeply encrypt the key, and simultaneously achieve double encryption of the video player and video data files to form a terminal End-to-end full-link video security protection means that even if the video file is stolen, other applications will not be able to play it, making the video more secure.

4. User ID ticker

In the example, the user's ID and The phone number is displayed.

5.Digital dynamic watermark

The user ID, phone number or other information content is displayed on the video in the form of a dynamic watermark, so that the watermark appears irregularly on the video, which can trace the identity of the screen recorder and play a strong deterrent effect on ripping behavior.

6. Browser screen recording prevention
