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 multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
Broadband rotational spectroscopy unravels structural reshaping of isolated molecules in the gas phase to accommodate water

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
