First of all, these courseware and videos used for training or education are generally of two kinds: one is that the enterprise or organization has its own platform or app, and the students watch them online; the other is that the enterprise does not have a platform or app, and sells the videos to the students individually.
1. Online platforms (web or mobile app)
Students buy the video through the platform and watch it online. Downloading and copying for dissemination are prohibited. This mode requires the online platform or app to dock the video encryption SDK program to realize the encrypted playback of the course video. It is featured by:
a. Video files are encrypted on the server, during network transmission, and in the browser cache, eliminating short-circuit vulnerabilities and preventing playback even if they are downloaded.
b. Keyframe encryption technology. The encrypted file is only increased by a few dozen bytes, basically the same size as before encryption, without increasing the pressure of network transmission.
c. Support for randomly displaying member names on the video with marquee effect(to prevent recording), customizing logos, and playing opening and closing ads.
d. Permission control and anti-theft chain function: restrict non-paying users from watching and illegally downloading videos. You can restrict users from accessing the player only after logging in to a certain website.
e. Different users have different keys to activate the player which cannot be shared. One user's video being cracked will not affect other users.
f. Pop-up function. A pop-up window will pop up during playback. The user must answer the question to continue watching.
We also support encryption for applets, H5.
2. Offline encryption.
This way is more widespread and popular. The teacher transmits the encrypted video to the student, restricting the student's personal use and avoiding malicious dissemination. For this one, we recommend using one-machine-one-code software, which can be bound to the student's computer or cell phone, video can not be played if copied to other equipment. It protects the rights and interests of the video owner. This encryption is higher and more prominently secure. It can also expand more functions:
a. Support binding customers' hardware (computer, tablet, cell phone) to playback video.
b. Video can be encrypted into exe format. Users can play it by double-clicking it.
c. Support watermark logo
d. Support preview image. Show preview image before playback
e. Offline issuance of playback license. Users can get it by phone, email, etc.
f. Support online activation code, more convenient.
g. Encrypt the whole video, only decrypt it frame by frame during playback.
h. Anti-reverse crack function.
...
The above are some of the encryption functions. If you need higher level and personalized encryption, you can customize your own private protocol encryption software. It is more expandable, such as modifying the interface UI, adding course lists, downloads, and so on.
