In this course the student has to get to know new transfer protocols for the Internet, how to structure network applications and how to design and deploy services for web distributed applications. It must also gain the ability to deal with security problems in the network and, in particular, on the web, and gain insight into the problems of secure access to the information, privacy and digital rights. Finally, students will become familiar with the systems of distribution and management of multimedia content, including knowledge of protocols, standards and mechanisms for representation, exchange, security and interoperability.

Laboratory practices

During the course, a project will be done in the lab sessions in small groups. The project aims to develop a web application that will integrate the concepts of the subject. The project breaks down into three phases of two sessions each, covering topics such as web applications, web services and security. Each session corresponds to a delivery which is evaluated independently. The work performed on the project is incremental, since deliveries depend on the previous ones so as to achieve a more complete functionality.

Teaching methodology

This course should give an overview and the most technically and practically possible view of the problems and solutions to the development of Internet secure multimedia applications. Although, as it covers many topics, there is an important descriptive approach, the subject is organised from a practical point of view with many use cases and laboratory practices.

For this reason, the teaching methodology will use examples and problems to introduce the concepts to help students to attain the skills needed. Also, we will try to encourage interaction with students considering real situations to discuss their possible solutions.

On the other hand, the laboratory practices will complete the skills and knowledge acquired in theory / problems classes. Practices will have an integrative perspective (project type) since students will built small modules to be integrated in a final practice.

Evaluation methodology

2 partial exams (P1, P2). P1 includes topics 1 to 3; P2 includes the rest.
1 assignment that includes presentation, discussion and documentation.
Laboratory (L): Several deliverables.
Final exam not mandatory (F) with two parts (F1, topics 1 to 3, and F2, rest of topics).
Daily "mini-tests" that increment the mark of the partial exams (Incr)
Grade: (Nt * 0,4) + (Na * 0,3) + (Nl * 0,3); Nt is the grade for theory, Na for the assignment and Nl for laboratory.
Nt = MAX (Nt partial exams, Nt with final exam)
Nt partial exams = (P1+P2)/2 * Incr, where Incr = 1 + 0,025 * (ADDITION (tests grades) / Number of tests)
Nt with final exam = 0,5 * MAX (P1, F1) + 0,5 * MAX (P2, F2)
Nl = (Deliverables grade * 0.5) + (Interviews grade * 0.5)
Na = (0,5 * Content) + (0,3 * Presentation) + (0,1 * Discussion) + (0,1 * Participation)
