ABSTRACT

This chapter discusses the business, social, legal, and technical aspects of Digital Rights Management (DRM) in detail. The term DRM refers to a set of technologies and approaches that establish a trust relationship among the parties involved in a digital asset creation and transaction. Designing an economically viable DRM system is particularly challenging for low-valued digital assets. The DRM system depends on strong encryption schemes and ties the decryption to the device on which it is decrypted. The DRM system is expected to build trust among the parties by meeting the digital rights of each party. Designing a DRM solution for the dedicated setup is easier compared to the open and general setups, because the owner or distributor is connected to the consumer through a dedicated transmission channel and rendering hardware and software. The challenges in solving DRM for digital video are multifaceted. Video files are large and they require much storage space.
