OneButtonPIN increases security for blind and low-vision tech users

New authentication method helps protect data from privacy attacks Working closely with blind and low-vision (BLV) users, researchers at the University of Waterloo and the Rochester Institute of Technology have developed a new authentication method that could help BLV technology users more securely access their devices. The new method, OneButtonPIN, allows users to input PIN codes using a single large button and a series of haptic vibrations. People with BLV frequently express frustrations with existing authentication methods such as drawing patterns, fingerprint and face scans, and PIN codes. Some methods are difficult to use effectively without visual data. Others are vulnerable to privacy attacks. OneButtonPIN addresses these security issues by using haptic vibrations imperceptible to outsiders. When prompted to enter a PIN code, the user presses and holds a large button on their smartphone screen.
