Digital content protection

 

Organization:

  • Teaching Load / Total Load : 45/90
  • Lectures/Exercices/Labs/Final Exam 1: 36/0/9/0 

Assessment:

Two-student group project (P) (45h) linked to real industrial applications or to national/European research projects with oral defense (D).

Final mark = Average (P, D)

Objectives:

  • To be able to analyze, define, evaluate, and design the protection level of multimedia systems and services.
  • To be able to accurately identify the requirements of the secure systems at the core of new Internet services (e-commerce, multimedia databases, video on demand, social networks, ...).
  • To master the scientific paradigms underlying steganography, cryptography, watermarking and fingerprinting.
  • To be able to turn into practice the intellectual property rights management, identification, authentication, confidentiality, and, more generally, traceability.
  • To be able to design and implement reliable solutions for the emerging watermarking applications (as resulting from the theoretical/industrial/standardisation relationship).

Course outline:

  • 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 concept
  • 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: 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
  • 3D graphics: from CAD objects to virtual reality avatars
  • Stereoscopic video: offering an additional view in watermarking. - 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 indexin
  • Intermodal watermarking
