Digital Watermark — Social-DRM

All digital content offered by "Zentrale Medien GmbH" receives a digital watermark prior to download.

The digital watermark is our innovative solution for a secure release of digital content and helps to prevent copyright violations.

Purchased documents can be clearly attributed to the authorised users. This way, abuse of copyrighted documents is prevented without any technical efforts.

Digital Rights Management — DRM

On request, DRM systems can be employed to protect the publishers’ documents.
