Abstract
An improved authentication, identification, and/or verification system is provided in various embodiments. The system is provided for use in relation to provisioning access or establishing identity in relation to one or more human users, and may be used in a single site/scenario/system, or across multiple sites/scenarios/systems. A combination of biometric modalities and authentication mechanisms having diverse characteristics are utilized to establish identity, the diverse characteristics being utilized to modify aspects of identity management and access provisioning.
Core Innovation
The invention provides an adaptive identity verification system and method for provisioning identity verification in relation to an identity of one or more users. The system automatically adapts user identification decisions to a user identification control challenge request by receiving one or more identity information data sets obtained from one or more identity sensor devices. Upon each attempted verification against identity template data corresponding to a specific user of the one or more users, the system modifies an adapted confidence score aggregated from each contribution to the adapted confidence score from each attempted verification.
The modification includes modifying a baseline confidence contribution score from each successful verification in accordance with one or more identity attributes to generate the adapted confidence score aggregated from each baseline confidence contribution score. The contribution to the adapted confidence score is tuned based on at least one of a false rejection rate or a false positive rate associated with a modality corresponding to the attempted verification. The false positive rate or the false negative rate is periodically updated based on tracked infrastructure correlation data associated with the modality and additional modalities contributing to the adapted confidence score, where correlations in the tracked infrastructure correlation data lead to an increase in the false positive rate or the false negative rate for correlated modalities.
Responsive to the adapted confidence score being reduced below a required confidence score threshold, the system generates a response signal representing an access provisioning signal for controlling an access control mechanism to deny access and to request an additional user identification control challenge. The same adaptive confidence-score and challenge/deny behavior is also described for the adaptive identity verification method and for a non-transitory computer readable medium storing machine interpretable instructions.
Claims Coverage
The partial content provides three independent claims (adaptive identity verification system, adaptive identity verification method, and a non-transitory computer readable medium). Each independent claim centers on an adaptive confidence-score aggregation mechanism tuned by modality error rates and periodically updated using tracked infrastructure correlation data, with deny-access and additional challenge generation when a required confidence threshold is not met.
Adaptive confidence-score modification for challenge-driven verification
Automatically adapting user identification decisions to a user identification control challenge request by, upon each attempted verification against the identity template data corresponding to a specific user, modifying an adapted confidence score aggregated from each contribution to the adapted confidence score from each attempted verification.
Modality-specific tuning using baseline confidence and error rates
Modifying a baseline confidence contribution score from each successful verification in accordance with one or more identity attributes to generate the adapted confidence score, wherein the contribution to the adapted confidence score is tuned based on at least one of a false rejection rate or a false positive rate associated with a modality corresponding to the attempted verification.
Periodically updated infrastructure-correlation-driven adjustment of error rates
Periodically updating the false positive rate or the false negative rate based on tracked infrastructure correlation data associated with the modality and additional modalities contributing to the adapted confidence score, wherein correlations identified in the tracked infrastructure correlation data lead to an increase in the false positive rate or the false negative rate for correlated modalities.
Deny access and request additional challenge when confidence falls below threshold
Responsive to the adapted confidence score being reduced below a required confidence score threshold, generating a response signal representing an access provisioning signal for controlling an access control mechanism to deny access and to request an additional user identification control challenge.
Across the independent claims, the key coverage is for adaptive identity verification that aggregates and modifies an adapted confidence score for attempted verifications, tunes modality contributions using false positive/false rejection (and false negative) rates, periodically updates those rates based on tracked infrastructure correlation data that increases error rates for correlated modalities, and denies access and requests an additional challenge when the adapted confidence score falls below a required threshold.
Stated Advantages
Provides an adaptive identity verification approach that automatically adapts user identification decisions to a user identification control challenge request.
Improves decision adaptation by tuning modality contributions based on false rejection rate or false positive rate and by periodically updating error rates using tracked infrastructure correlation data.
Controls access by denying access and requesting an additional user identification control challenge when the adapted confidence score is below a required confidence score threshold.
Documented Applications
Provisioning identity verification for an identity of one or more users, including an access control mechanism that denies access and requests an additional user identification control challenge.
