Abstract
A computing device may be configured to authenticate a user for access control, and may include at least one ground electrode configured for contact with a user, an impedance sensor coupled to the least one ground electrode, where the impedance sensor may be configured to perform a measurement based on a touch input from the user, a memory which stores instructions, and a processor, coupled the impedance sensor and the memory, where the processor may be configured to execute the instructions. The instructions may cause the processor to: receive the touch input from the user, receive an impedance value based on the touch input measured by the impedance sensor, and determine whether the received impedance value corresponds to at least one stored impedance value associated with a user profile.
