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.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
