Abstract
Methods and systems are provided for an AdHoc enrollment process. A user may be able to enroll and be verified by a system for a variety of actions or authentications without being forced to turn over personally identifiable information and without having to formally enroll. The system may compare captured biometric information with existing biometric information and may identify the user without the use of personally identifiable information.
Core Innovation
An AdHoc biometric enrollment/authentication process registers and enrolls a user biometric by receiving first biometric information associated with a user at a first time, extracting first biometric data from the first biometric information, and generating a first template based on the first biometric data. The process then enrolls the user by receiving the first biometric information associated with the user at a second time after the first time, extracting second biometric data from the first biometric information, and generating a second template based on the second biometric data.
The process compares the second template with the first template to generate a confidence value reflecting a degree of similarity between the first template and the second template. Based on comparing the confidence value to a threshold value, the process sends at least one of a confirmation and an alert.
The disclosed approach can include template generation without requiring personally identifiable information, using privacy-preserving session tags as metadata. A system can extract biometric data from first and second biometric information, generate a first template that includes a fusion of the first biometric data and the second biometric data, compare the first template with at least one stored template to generate a confidence value, and send a confirmation or an alert based on comparing the confidence value to a threshold value.
Claims Coverage
The independent claims include 3 inventive claim scopes: a method for AdHoc registration and enrollment with confidence-threshold confirmation/alert signaling, a system architecture with fused biometric templates and confidence-threshold confirmation/alert signaling, and a system architecture that compares templates and sends confirmation/alert based on a confidence-threshold comparison. Each independent claim centers on generating templates from biometric information, comparing templates to produce a confidence value of similarity, and sending at least one of a confirmation and an alert based on threshold comparison.
AdHoc biometric registration with confidence-threshold confirmation/alert
Receiving first biometric information associated with a user at a first time, extracting first biometric data from the first biometric information, and generating a first template based on the first biometric data; receiving the first biometric information associated with the user at a second time after the first time, extracting second biometric data from the first biometric information, and generating a second template based on the second biometric data; comparing the second template with the first template to generate a confidence value reflecting a degree of similarity between the first template and the second template; and sending, based on comparing the confidence value to a threshold value, at least one of a confirmation and an alert.
Fused template comparison with confidence-threshold confirmation/alert in a system
Receiving first biometric information and second biometric information associated with a user; extracting first biometric data from the first biometric information and second biometric data from the second biometric information; generating a first template that includes a fusion of the first biometric data and the second biometric data; comparing the first template with at least one stored template to generate a confidence value reflecting a degree of similarity between the first template and the at least one stored template; and sending, based on comparing the confidence value to a threshold value, at least one of a confirmation and an alert.
Template similarity confidence-threshold decision with confirmation/alert in a system
Receiving first biometric information associated with a user; generating, based on the first biometric information, a first template; comparing the first template with a second template to generate a confidence value reflecting a degree of similarity between the first template and the second template; comparing the confidence value to a threshold value; and sending, based on the comparing of the confidence value and the threshold value, at least one of a confirmation and an alert.
Across the independent claims, the coverage is unified around generating biometric templates, producing a confidence value that reflects similarity between templates, and deciding between confirmation and alert by comparing the confidence value to a threshold value; one claim further requires enrollment at two times and another requires generating a fused template from first and second biometric data.
