Researchers from the Georgia Institute of Technology have created a new touch-based smartphone security system that protects your phone even if an unauthorized user manages to unlock it. The technology, known as LatentGesture, was tested in a Georgia lab tech study using Android phones. Results were promising: it was accurate for 98 percent of phones and 97 percent of tablets. The system could ultimately be used to monitor a users touch signature while he/she is active on the phone; if the signatures do not match, the system can lock them out.”]
