Video fingerprinting and encryption principles for digital rights management
Deepa Kundur, K. Karthik · Proceedings of the IEEE · 2004
This paper provides a tutorial and survey of digital fingerprinting and video scrambling algorithms based on partial encryption. Necessary design tradeoffs for algorithm development are highlighted for multicast communication environments. We also propose a novel architecture for joint fingerprinting and decryption that holds promise for a better compromise between practicality and security for emerging digital rights management applications.
