Error-correcting codes are one of the triumphs of the digital age. Theyre a way of encoding information so that it can be transmitted across a communication channel such as an optical fiber or a wireless connection with perfect fidelity, even in the presence of the corrupting influences known as noise.
Satellite telephony was thought to be secure against eavesdropping. German researchers at the Horst Gortz Institute for IT-Security (HGI) at the Ruhr University Bochum (RUB) have cracked the encryption algorithms of the European Telecommunications Standards Institute (ETSI), which is used globally for satellite telephones, and revealed significant weaknesses. In less than an hour, and with simple equipment, they found the crypto key which is needed to intercept telephone conversations. Using open-source software and building on their previous research results, they were able to exploit the security weaknesses.
Researchers from North Carolina State University have developed a new technique that allows graphics processing units (GPUs) and central processing units (CPUs) on a single chip to collaborate boosting processor performance by an average of more than 20 percent.
(PhysOrg.com) -- A Swedish company focused on mobile-device imaging technology, Scalado, plans to show object-removal software for the smartphone at this months Mobile World Congress in Barcelona. The software lets you remove anything in a photo that youre taking, with just a screen tap. The only requirements are that the object has to be moving -- unwanted pedestrians as you try to capture something on the city streets, for example -- for the application to capture and delete.

The amount of data sent to or from mobile gadgets around the world annually will rocket to hit the equivalent of 33 billion full-length DVD films by the year 2016, computer networking titan Cisco forecast on Tuesday.
Providing high-bandwidth communications for troops in remote forward operating locations is not only critical but also challenging because a reliable infrastructure optimized for remote geographic areas does not exist. When you introduce additional needs, such as communication support for data feeds from Unmanned Aerial Vehicles (UAVs) transmitting information to troops on patrol in remote areas, you face a host of new challenges where dropped signals can create a serious threat to a warfighter's situational awareness.
A US Supreme Court decision requiring a warrant to place a GPS device on the car of a criminal suspect leaves unresolved the bigger issue of police tracking using mobile phones, legal experts say.
The International Telecommunication Union said Friday its World Radiocommunications Conference (WRC-12) has agreed a treaty aimed at revising the radio frequency spectrum to speed up mobile services.
