Abstract
Examples of privacy preserving authentication are provided. A system may obtain a first input from a user on a touchpad. The touchpad may include a sensor array with multiple force sensitive resistors. Further, the system may identify a set of sensor electrodes of the sensor array that may be actuated on receiving the first input. The system may further determine a region of interest on the touchpad. Furthermore, the system may construct various matrices indicative of position, pressure, and directional characteristics associated with the user input. Furthermore, the system may generate a feature vector based on processing the matrices through a neural network. Furthermore, the system may generate an encrypted feature vector based on encrypting the feature vector by using a private key of the user and a homomorphic encryption function. The system may further provide an authorized access to the user based on performing authentication of the user using the encrypted feature vector.
