Abstract

A user is authenticated based on feature data of a target such as a body-part or other object obtained by a touchscreen of a computing device. When the user positions the target to interact with the touchscreen, interaction data is gathered. Feature data of the target is determined from the gathered interaction data. The feature data is used to identify one or more of the target and the user. Various actions are executed based on the identification and authentication of the user.
