System and method for leveraging microexpressions of users in multi-factor authentication

Abstract:

A system for identifying a user using microexpressions presents training media items to the user. The system captures a first set of microexpressions of the user in reaction to the training media items. The system, based on the first set of microexpressions, determines baseline features indicating reactions of the user to the training media items. The system presents test media items to a person. The system captures a second set of microexpressions of the person in reaction to the test media items. The system, based on the second set of microexpressions, determines test features indicating reactions of the person to the test media items. The system determines whether the person is the same as the user by comparing the baseline features to the test features. The system determines that the person is the same as the user if the test features correspond to the baseline features.
