This subject covers research aspects of the very active area of Internet applications and its security. Focus is made on multimedia applications, but other areas, such as eHealth, are also considered. Therefore, content, metadata and transmission protocols are relevant.
Protection and privacy are considered for information and protocols, so all aspects of Internet security for applications will be reviewed.
Standards to achieve interoperability are key for understanding the relevant problems and their solutions.
Topics will be introduced, analyzed and discussed, focusing on the new approaches and techniques. Students will work on specific assignments that will be discussed with their peers in order to understand current solutions and think on alternative ones.

Teaching methodology

The course is very interactive with some introductory topics from the Professor and a few assignments in which students present papers and discuss conclusions.

In particular, students prepare two assignments for analysis and discussion on topics of recent research and standards, and another one more on research.

In the first two assignments, students present the results of their analysis and lead a discussion on this with rest of students.

In the last one, students make a small research project led by the Professor (on a specific topic: what is done? what is not solved? ideas to solve it). They write a short paper and make a presentation where they answer questions and criticisms from the Professor and the other students.

Evaluation methodology

Test on the topics developed by the Professor (T).
2 assignments on analysis and discussion (A) and 1 assignment on research (R).
(A) Analysis & Discussion of a document. Students provide documentation + short presentation and lead class discussion. Students not presenting should make questions showing their understanding of the topics.
(R) Research work. Students provide documentation + “long” presentation + interview (if needed).
Final mark: (T * 0,3) + 2* (A * 0,2) + (R * 0,3)
Assessment of A includes:
Content (35%), Presentation (30%), Lead discussion (20%), Others' discussion (15%).
Assessment of R includes:
Content (35%), Presentation (25%), Questions (15%), Report (25%).
T mark could be increased (factor F) with the evaluation of n (number to define) “dairy short tests” (mark D for every dairy test):
Increase factor (F) = 0,25 * ( Σn Di )/ n
The increased T mark would be: T * (1+F). 0 <= F <= 0,25.
