Protect your course videos and educational content
Taalemy protects course videos and PDFs in several layers: only a student enrolled in the course receives a playback link, the link expires, the content shows the student's short name and a personal code, and every viewing session is recorded. The goal is to stop easy downloading, reduce unauthorized sharing and identify the source of a leaked copy, not to claim that copying is impossible.
- No original file or permanent download link
- Watermark with the student's short name and code
- PDF viewer without download or print
- Viewing sessions recorded for leak tracing
Why educational content needs protection
A paid course is a teacher's income. When a video is downloaded or its link is passed around in group chats, the teacher loses students who would have paid, with no way of knowing where the leak started.
How protected video playback works
Videos are hosted on a dedicated streaming service and play inside an embedded player, not as a file that can be saved.
- Before issuing a playback link, the server checks that the student is enrolled, the lesson is published and any required earlier lessons are complete
- The playback link is signed and temporary (valid for 20 minutes by default), so copying and sharing it does not help
- There is no download button and no direct link to the original file
A watermark unique to each student
The video shows the student's short name (for example “Omar G.”) and a six-character code tied to their account. The mark is small and semi-transparent; it appears for a few seconds in one corner, disappears, and returns in another corner so it does not disturb viewing.
Every 5 to 10 minutes a clearer mark appears near the top center for a few seconds, which raises the chance that the code is captured in any recording or photo of the screen. The watermark never includes the student's email, phone number or full name.
Protected PDF files
The teacher decides for each file whether downloading is allowed. When it is not, the original file link never reaches the browser: the file passes through Taalemy's server after the student's access is checked, and is shown one page at a time in a dedicated viewer.
- No download or print buttons
- Text selection and right-click are disabled
- A repeated diagonal watermark with the student's name and code on every page
Tracing the source of a leak
Each time a student opens a protected video or file, a viewing session is recorded against their account and the code shown in the watermark. If a leaked copy reaches you with the code visible, it can be matched to the student's account, and our support team can help you do that.
What protection can and cannot do
What it does
- Prevents access to the original video file or a permanent link to it
- Prevents people who are not enrolled from playing lessons
- Makes copied links useless once they expire
- Puts the student's identity on what they watch, which deters leaks and helps trace them
What no web platform can guarantee
- Fully stopping screen recording, or someone filming the screen with another device
- Stopping a recorded copy from being published; the watermark helps identify its source, not remove it
Frequently asked questions
Can a student download the original video?
No. There is no download button and no link to the original file; the video plays in an embedded player through a temporary link issued only to enrolled students.
Does Taalemy completely stop screen recording?
No, and no web platform can guarantee that. What Taalemy does is show the student's short name and code on the video, including a clearer mark that appears periodically, so the source of any published recording can be identified.
What does the watermark contain?
The student's short name and a six-character code linked to their account, with no email address, phone number or full name.
Do video links expire?
Yes. The playback link is signed and valid for 20 minutes by default, and it is only issued after the student's enrollment is checked.
Can PDF files be protected?
Yes. When downloading is turned off, the file is shown page by page in a viewer without download or print, with a watermark carrying the student's name and code. You can still allow downloads for files you want to share.
What should I do if a video from my course is shared?
Look for the code shown in the watermark in the shared copy, contact our support team to match it to a student account using the viewing-session records, and then take the appropriate action on that account.
