New Kwikset Touch-Screen Deadbolt Uses Button-Masking Technology for Extra Security
Kwikset began selling SmartCode 915 ($179), an electronic touch-screen deadbolt lock with technology designed to prevent “smudge” attacks. Kwikset’s SecureScreen technology requires users to tap two random numbers on the touch screen before entering the programmed access code, so unapproved persons can’t detect frequently used numbers and characters from oily residues left by fingers on the touch-screen surface, said the company Monday. SecureScreen encourages use of the full screen to mask the correct access code, it said.
