Scientists break satellite telephony security standards

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.

Remove software for smartphone can zap photo items (w/ video)

(PhysOrg.com) -- A Swedish company focused on mobile-device imaging technology, Scalado, plans to show object-removal software for the smartphone at this month’s Mobile World Congress in Barcelona. The software lets you remove anything in a photo that you’re 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. Also, the camera needs to stay still and focused on the subject while you touch each moving item chosen for removal.
