Our files are protected in a unique way that still deters unauthorized distribution without the customer losing any of the freedom and control they desire. (goodereader.com)
Digital rights management (DRM): You get to decide if your ebook file is protected by DRM, a safeguard that prevents unauthorized distribution. (authorsguild.org)
