Short for
digital rights management, a system for protecting the
copyrights of data circulated via the
Internet or other digital media by enabling secure distribution and/or disabling illegal distribution of the data. Typically, a DRM system protects intellectual property by either
encrypting the data so that it can only be accessed by authorized users or marking the content with a
digital watermark or similar method so that the content can not be freely distributed.
