Introduction to Digital Rights Management (DRM); Identifying, Tracking, Authorizing and Restricting Access to DigitalMedia
This book explains the fundamentals of digital rights management systems including identifying, tracking, authorizing and restricting access to digital media. You will learn how DRM systems help to protect and enforce copyrights, patents, trademarks, and other forms of intellectual property.
Digital assets can take various forms including audio, data and digital video. You will discover how it is possible to provide simple access to authorized users (paying customers) and how to restrict access to unauthorized users. Digital media content must be uniquely identified. The common identification codes that may be assigned to digital media include ISBN (books), ISSN (magazines), DOI (multimedia) and watermarks. You will learn that DRM systems may include a DRM controller, digital asset manager and DRM packager that allow DRM systems to receive requests for digital assets, to find and retrieve the assets and to packages (encode) to protect the assets during delivery and use.
