Content:
Focus of this lecture is the security of multimedia applications. The student will obtain the knowledge to apply multimedia specific security protocols to media like image, audio and video.

• Motivation, Introduction and Basics
• Intellectual Property Rights (IPR), Digital Rights Management (DRM)
• Access Protection - Pay-TV, Scrambling and Encryption of Video-and Audio Data, Services on Encrypted Data
• Hidden Communication: Steganography
• Digital Watermarking - Robust Watermarking, Fragile Watermarking
• Perceptual Hashing
• Digital Forensics and Digitized Forensics
• Multimodal Biometrics

Exam:
Beginning with summer term 2014 the oral exam used in this course for a decade was replaced by a combination of presentation and seminar paper (in German: "Referat") on a given course topic.
The topics are drawn from the fields of hidden communication, digital watermarking, perceptual hashing, forensics and biometrics. Each topic is restricted to a student team of 2 students and focusses on the the realisation of an own setup of demonstrators and experimental setup (requires code adaptation) of a media security mechanism (e.g. an image manipulation detection algorithm), the collection and documentation of a media data repository generated as a joint effort by all student teams and the evaluation of the mechanism using the media data repository generated as a joint effort by all student teams.

Due tue the increased effort for the students as well as teaching staff, the course size is restricted to 20 participants.
