Thanks to EditionGuard s you have access to the same DRM protection used by giants like Barnes & Noble and Kobo for a flat monthly rate with no setup costs. Here is an overview of the three primary forms of DRM protection for e-books. Password Protection Using various apps such as Adobe Acrobat or the native MacOS alternative Preview you can password-protect your PDFs and e-pubs. There is no flexibility in terms of what users can access - they either have the password to open the file or not. This can deter users but the encryption is less than industry-standard and can easily be removed for free using various services and solutions.

This discourages sharing as a file with your personal information attached to it means any copy of it is trackable and attributable to you. Industry-Standard DRM Protection DRM protection with secure encryption and the versatility to control what users can and cannot do with your PDFs and e-pubs is an investment. The security of these services relies on them constantly being one step ahead of the thousands of people attempting to decrypt their solutions for their motives be they business or personal.
