From the press release:
CyberWolf Inc., an Adobe Content Server Solution Provider, announces offering that enables publishers to sell Adobe DRM secured content directly from their own ecommerce sites. Adobe Content Server DRM has been adopted by a number of major players within the publishing industry and, via the new CyberWolf Download Service (CDS), is now available to most any publisher.
The CyberWolf Download Service allows publishers to select from Adobe Content Server DRM attributes, social DRM techniques, or to sell with no DRM on a product by product basis. Adobe DRM attributes can be assigned to files in PDF or ePub formats. These attributes allow control of content expiration dates and the ability to copy or print among other characteristics. The social DRM approach is supported with PDF files and stamps the content with a watermark that identifies the purchaser. Content marked in this fashion is less likely to be distributed via file-sharing networks. The CDS also supports the sale of any file type with no DRM.
