User authentication based on confidence levels for identity predictions

A non-transitory computer-readable storage medium, storing one or more programs configured for execution by one or more processors of a computing device, the one or more programs including instructions for:

• associating authentication criteria with respective actions of the computing device, the authentication criteria for each respective action including a confidence threshold;
• receiving, by the computing device, an interaction from an individual within a recognition range of the computing device;
• capturing, by the computing device, recognition information including biometric data describing the individual;
• calculating a confidence level associated with a predicted identity of the individual based at least in part on the recognition information;
• identifying an action of the computing device based on the interaction;
• determining the authentication criteria associated with the action are satisfied based at least in part on the confidence level exceeding the confidence threshold of the authentication criteria;
• and
• responsive to determining the authentication criteria associated with the action are satisfied, performing the action.
