General description and relevant information The course of Multimedia Security describes briefly the multimedia contents, the industry and the threats, i.e. the problem of copyright protection in the Information Society. Digital contents or applications can be copied and distributed via communication networks at low cost (without cost). This damages the owners of these goods because a high number of users can access the contents or programs without compensating its rightful owner. This problem has been approached from two different viewpoints, but complementary; copy prevention and copy detection (illegal copy). The copy prevention includes technologies that do not allow accessing to content or applications to unauthorized users. Authorized users are those who have purchased a legitimate copy of the product (or the access to the product). The copy detection comprises the technologies allow to know who is the legitimate user (watermarking) or even prove who has redistributed the copy (Fingerprinting). In both cases, we must find the copy.

  Description
Activitats Introductòries The first session introduces the subject, describing the objectives, schedule, and how the course will be assessed.
Sessió Magistral The teacher explains the units of the course.
Pràctiques a través de TIC en aules informàtiques The students have to develop a copy detection technique.

The practice will be done in groups of two.

The students will present their works in class. All works (techniques developed) compete between them. The best work obtains the best grade.
Atenció personalitzada Practicals using information and communication technologies (ICTs) in computer rooms:

The students can ask questions related with the subject to the teacher. They can do their questions in class, to his office in office hours, through email, or Moodle.

Lecture:

The students can ask questions related with the subject to the teacher. They can do their questions in class, to his office in office hours, through email, or Moodle.

Other comments and second exam session

Students who do not pass the subject in the continuous assessment have to carry out a examination on the second call, and deliver the practice. The exam will consist of three parts, corresponding to the three parts of the course (first part: units 1 and 2 - second part: units  3 and 4 - third part: unit 5). Each part is scored out of 10 points. The students have to obtain at least 4 in each of the parts to pass the examination, and the sum of the three parts must be greater than 15 points. The practice must have a minimum of five to pass the course. Otherwise, the students can no pass the course.

Students may not bring any electronic devices on the written tests.
