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 Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
