Adaptive biometric and environmental authentication system

A device comprising:

• a user identity reference module that is configured to maintain user identification items stored in a secure memory, at least one of the user identification items at least partially identifying a reference user;
• a passive data aggregator that is configured to receive and aggregate data items that are passively collected by at least one device that is in proximity to a user;
• a user identity confidence level generator that is configured to generate a user identity confidence level that indicates a confidence that the user in proximity to the at least one device is the reference user based at least in part on a comparison between at least one of the passively collected data items and at least one of the user identification items, and to update the user identity confidence level as additional passively collected data items are received;
• and
• an authentication module that facilitates user authentication based at least in part on the user identity confidence level.

A computer program product comprising instructions stored in a tangible computer-readable storage medium, the instructions comprising:

• instructions to receive passively collected data items from at least one device that is in proximity to a user;
• instructions to determine a user identity likelihood value that indicates a likelihood that the user corresponds to a reference user by comparing at least one of the passively collected data items to a user identity reference model associated with the reference user;
• instructions to update the user identity likelihood value as additional passively collected data items are received;
• and
• instructions to facilitate authentication requests associated with the reference user based at least on the user identity likelihood value.

A device comprising:

• processing circuitry that is configured to:
• gather bio-data and environmental data, wherein at least one of the bio-data and the environmental data is received from another device;
• evaluate the bio-data and the environmental data to identify a first authentication rating;
• compare the first authentication rating with an authentication challenge requirement;
• interact, in response to the comparison, to bolster a contribution to the first authentication rating;
• and
• identify a second authentication rating that meets the authentication challenge requirement.
