IPR Protection Techniques
• Goals
 Access / usage control
 Copy management
 Copyright certification, authentication
• Solutions
 Encryption : Scrambling of data, allow descrambling to
authorized users only
 Watermarking: Imperceptible embedding of
copyright/access control data in digital media
• Efficient solutions are yet to be found
