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
Introductory activities The first session introduces the subject, describing the objectives, schedule, and how the course will be assessed.
Forums of debate The students can share their questions with the teacher and their mates in the Forum. The teacher or any student can reply the questions.

The collaboration between them is part of the learning process.
Assignments According to the course schedule, students have to prepare the units of the course.

The course schedule defines when the units begin and end, i.e. students have the assignment to study the unit during this period.

If students have some question about the units, they can send them to the teacher (e-mail or Forum) or to their mates (Forum).
Reading written documents and graphs According to the course schedule, students have to prepare the units of the course.

The course schedule defines when the units begin and end, i.e. students have the assignment to study the unit during this period.

If students have some question about the units, they can send them to the teacher (e-mail or Forum) or to their mates (Forum).
Personal attention
The students can ask questions related with the subject to the teacher through email.

Personalized attention
Description
Practicals using information and communication technologies (ICTs): The students can ask questions related with the subject to the teacher. They can do their questions through email, or Moodle (they can send a private message to the teacher). Assigments: The students can ask questions related with the subject to the teacher. They can do their questions email, or Moodle (they can send a private message to the teacher). Forms of discussion: The students can share their questions with the teacher and their mates in the Forum. The teacher or any student can reply the questions. The good contributions in the Forum will be considered in the final evaluation. Personal tuition: The students can ask questions related with the subject to the teacher through email.

The students have to perform two practical works.

The first practical work comprises the units 3 and 4, and the second the unit 5.

The practical works are individual.

Both practical works have the same weight, i.e. a 40% each of them.

Passing both practical works is required to pass the course, i.e. the students have to obtain at least 5 in each of the practical works to pass the subject.

Other comments and second exam session

Students who do not pass the subject in the continuous assessment have to carry out an ICT practical and an oral test.

The practical work consist of three parts, corresponding to the three parts of the course:

-Units 1 and 2.

-Units 3 and 4.

-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.

Moreover, students have to conduct an oral test of the subject (all units).

The test is conducted via Skype or other appropriate technology.

Passing the test is required to pass the course.
