AbstractWe invent a novel context aware privacy enhancing keyboard (PEK) for touch-enabled devices to keep users safe from various password inference attacks. When a user inputs normal text like an email or a message, PEK shows a normal QWERTY keyboard. However, every time a user of a touch-enabled device presses a password input box on the screen, we will randomly shuffle the positions of the characters on the keyboard and show this randomized keyboard to the user. PEK was released on the Google Play in 2014, but the number of installations is below our expectation now. For the purpose of usable security and privacy, we design a two-stage usability test and perform extensive experiments to evaluate the user experience of PEK and discover the reason behind the lukewarmness of using PEK. We implement two new features so as to improve PEK based on the feedback of usability tests.
