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.

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...
What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...
For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
