DRM Protection for Books
Protect your digital publications from unauthorized copying and sharing with Euron Systems' eBook DRM technology.
How Book DRM Works
When you enable DRM for an eBook:
- The book content is encrypted using AES-256 encryption.
- Each reader session generates a unique decryption token tied to the student's account.
- The content is decrypted in real-time during viewing — no unprotected copy is ever stored on the device.
- Screenshots and screen recording are discouraged through visible watermarking.
