Content protection

Content protection puts the student's name on the material they open. For example: Ana downloads the PDF handout, and the PDF comes with her name and document. If the handout shows up in a group, you know where it came from.

The most important rule: the watermark does not stop copying. It does not block downloads, screenshots or screen recording. It shows who copied, and so it discourages sharing.

How it works

The screen is in Settings → Security → Content protection. This kind of protection is also called social DRM. The screen has two tabs:

The two tabs are one form. Change what you want on both. Then click Save now once, in the bar that appears at the bottom.

The protection applies from the next time the student opens the file or the video. What they already downloaded does not change.

Document Protection

Show watermark on documents stamps the student's name and document on every PDF they download in the student area. If the student has no document on file, the watermark uses their email.

Which files get the watermark:

• PDFs attached to lesson content, through the editor's file blocks;
• PDFs attached to acceptance terms;
• PDFs attached to the FAQ.

Images, spreadsheets and other formats are delivered as uploaded. The watermark stays on until someone turns it off.

The watermark's look

With the watermark on, the Customization block changes its look:

Each click makes a new PDF

Each click on the file makes a new PDF, with the details of whoever clicked. That PDF's address expires within minutes. So a link that is copied and passed on stops opening.

Video Protection

Cademí does not host video. Each lesson stores the link of a player (Modules and lessons). So video protection depends on the player. Each player has its own block, and each block only changes lessons with a video from that player.

YouTube

Show identification on videos replaces the YouTube player with a custom Cademí player. In a corner of the video, this player shows a "Licensed for" badge with the student's name and document (or email). In Position, choose Top left or Top right.

Attention: this is where most mistakes happen. The custom player has fewer controls than YouTube's:

• It has: play and pause, back and forward 10 seconds, a progress bar, volume and fullscreen.
• It does not have: playback speed, captions or quality selection.
• When the student pauses, the picture goes black. This way, YouTube's suggestions of other videos do not show.

Before you turn it on, check whether your students use captions or watch at a faster speed.

Panda Video

Show watermark on videos asks Panda Video to show the student's name and document (or email) over the video.

The watermark is a feature of Panda Video itself. Set it up there first.

1. In the Panda Video dashboard, turn on the DRM (watermark) feature.
2. Still in Panda Video, put the videos you want to protect in a group.
3. In that group's settings, copy the group ID and the secret key.
4. In Cademí, turn on Show watermark on videos.
5. Under Integration credentials, paste the ID in Group ID.
6. Paste the secret key in API Secret.
7. Click Save now.

Without both fields, the screen does not save with the watermark on.

The watermark does not show when you open the lesson from the dashboard, without a student. Only a signed-in student has details to put on the watermark. The details of the feature belong to Panda Video: plans, style and when the watermark appears.

VdoCipher

VdoCipher works with or without the integration:

• Without the integration, the video plays through the link or the embed code. No one is identified.
• With the integration, Cademí asks VdoCipher for an authorization for each student, at each play. VdoCipher records who watched each video.

To turn on the integration:

1. Turn on Enable API integration.
2. In API Secret, paste the API key from your VdoCipher dashboard.
3. Under Integration features, turn on the optional ones you want (see below).
4. Click Save now.

Without the API Secret, the screen does not save with the integration on.

The optional features:

• Show watermark on videos: the student's name and document (or email) appear over the video. The watermark moves around from time to time.
• Restrict playback to your domain: the video does not play when someone embeds it outside your members area.

Videofront

Show watermark on videos sends the student's name and document (or email) to the Videofront player. Videofront uses these details to identify the student.

1. Turn on Show watermark on videos.
2. In Integration token, paste the API token from your Videofront dashboard.
3. Click Save now.

Without the token, the screen does not save with the watermark on.

When to use it

The watermark does not replace the device limit (Authentication). The limit discourages lending the password. The watermark discourages passing the material on. Use both together.
