Securely entering sensitive information using a touch screen device
In some examples, a computing device may determine, based on sensor data, that the computing device is in a public environment. In response, the computing device may display an entry wheel to enable a user to enter a password. The entry wheel may include multiple input symbols arranged equidistant around a circle. In some cases, one or more geometric patterns linking a portion of the input symbols may be displayed. After receiving an individual character of the password, the computing device may display the entry wheel rotated a number of positions in either a clockwise or counter-clockwise direction and display zero or more of the geometric patterns. After all the characters of the password have been received, the computing device may determine if the password matches a previously stored password. If the password matches, the computing device may transition from a low power state to an active state.
