The digitalising of information has opened up a great number of possibilities for many economic sectors which, using new technologies, have managed to considerably bring down costs of the various processes involved in their economic activity. Likewise, the spread and development of Internet has provided them with the possibility of making use of new schema for the faster and more economic distribution of materials than before, as well as immediate access to a potentially worldwide market. Nevertheless, this situation has brought with it the ease of illicitly accessing their products by millions of users who, moreover, can easily exchange them on the Net, thus violating the copyright associated with a large number of these items. These practices, generally falling under the term ‘piracy’, are currently one of the main issues for concern for almost all players in this sector, who are constantly demanding solutions to the problem.
In this context, watermarking and, more concretely, fingerprinting, are the basis for the majority of the solutions proposed to date, although a universal solution to resolve the problem completely has yet to be found.
The general aim of this thesis is to provide a definition for a new distribution model enabling the establishment of new schema for carrying out transactions with digital content, respecting all the rights involved such as authors’ copyright, clients’ rights to privacy and anonymity regarding acquisitions, etc., and with additional characteristics regarding simplicity and performance that ensure the viability of the said model.

A Swedish-German team of researchers has cleared up a key process for the artificial production of silk. With the help of the intense X-rays from DESY's...
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...
An important step towards a completely new experimental access to quantum physics has been made at University of Konstanz. The team of scientists headed by...
Yersiniae cause severe intestinal infections. Studies using Yersinia pseudotuberculosis as a model organism aim to elucidate the infection mechanisms of these...
Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
