	IMA5002	Digital content protection
	Coordination	Mihai MITREA
	Duration	45h
	ECTS	4
	Prerequisite	None
	Objectives	To analyze the secure systems at the core of new Internet services (e-commerce, multimedia databases, networked video games...). To present the scientific paradigms underlying steganography, cryptography and watermarking. To master the methods and technologies allowing for intellectual property rights management, identification, authentication, confidentiality, and, more generally, tractability.
	Content	Multimedia content protection: encryption, steganography and watermarking – a triptych of related, yet very different applications The MPEG approach: IPMP (Intellectual Property Management and Protection) - Basic concepts - Intrinsic limitations Digital watermarking - Basic concepts and models - Watermarking within the Information Theory framework - Advanced statistical models and methods for the multimedia protection - Channel coding and source coding for watermarking - Media type peculiarities in watermarking * Still images: the challenge of inserting a large quantity of information in a very small host * Video: the challenge of defeating the most daring pirates * Audio: the strongest transparency constraints * Text: a priori, an antagonism; a posteriori, a real life application * 3D graphics: from CAD objects to virtual reality avatars, a variety of problems that can be solved in a unitary manner - Watermarking and standards * Users, industry and research: three actors with different roles * When will the first standard emerge? - Watermarking and patents Beyond watermarking: joint approaches - Hybrid watermarking / compression and watermarking / encryption schemes - Watermarking and indexing: inserting descriptors into watermarks - Intermodal watermarking: inserting sound or subtitles into video
