Abstract
Mechanisms are provided to efficiently and effectively authenticate a user of a device. Passcode information such as passwords, pins, and access codes are obtained along with biometric information to periodically authenticate a user of a device. A user identity confidence score may be generated and continually modified by using data such as passcode information, biometric information, and/or user physical interaction characteristics information. If the user identify confidence score falls beneath a particular threshold, additional user authentication information may be requested.
Claims17
A method, comprising:
- receiving user passcode information associated with a user and a device;
- obtaining biometric data corresponding to the user, the biometric data obtained using the device;
- generating and modifying a user identity confidence score using the biometric data, wherein the user identity confidence score is generated using the user passcode information and the biometric data and wherein the user identity confidence score is modified using biometric data and a length of time since passcode information was last entered, wherein the user identity confidence score drops as time passes after receiving user passcode information and continues to drop even if additional biometric data or user physical interaction characteristics information is consistent with that of the user;
- requesting entry of user passcode information when the user identity confidence score falls beneath a particular threshold.
A system, comprising:
- an interface configured to receive user passcode information associated with a user and a device;
- a biometric sensor configured to obtain biometric data corresponding to the user, the biometric data obtained using the device;
- a processor configured to generate and modify a user identity confidence score using the biometric data, wherein the user identity confidence score is generated using the user passcode information and the biometric data and wherein the user identity confidence score is modified using biometric data and a length of time since passcode information was last entered, wherein the user identity confidence score drops as time passes after receiving user passcode information and continues to drop even if additional biometric data or user physical interaction characteristics information is consistent with that of the user;
- wherein user passcode information is requested when the user identity confidence score falls beneath a particular threshold.
A non-transitory computer readable storage medium, comprising:
- computer code for receiving user passcode information associated with a user and a device;
- computer code for obtaining biometric data corresponding to the user, the biometric data obtained using the device;
- computer code for generating and modifying a user identity confidence score using the biometric data, wherein the user identity confidence score is generated using the user passcode information and the biometric data and wherein the user identity confidence score is modified using biometric data and a length of time since passcode information was last entered, wherein the user identity confidence score drops as time passes after receiving user passcode information and continues to drop even if additional biometric data or user physical interaction characteristics information is consistent with that of the user;
- computer code for requesting entry of user passcode information when the user identity confidence score falls beneath a particular threshold.
