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.

Lecture notes:
The course material is provided in English.
