Sending your product digitally to customers always carried a certain amount of risk – after all, they could just share their ebooks with others, print and photocopy them etc. – so you need to adequately protect your IPR. You can quickly and easily transition to an ebook protection system that keeps you in full control over your eBooks, even after they arrive in the user’s hands. Ebook protection software that uses DRM can provide screenshot and print protection, per-user watermarks, expiry dates, the ability to disallow use in certain locations and lock use to specific devices, instant access revocation (for chargebacks), ebook use tracking (and more).
