Abstract
Disclosed herein are methods, apparatus, and systems for seamless biometric self-enrollment. The method including automatically: capturing, by a biometric capture device, biometric modality data for a user in response to a presentation of a user trusted credential for logical access or access to an object during an enrollment process, determining, by an enrollment system, whether biometric modalities for the user are stable, generating a biometric modality template for each unstable biometric modality, replacing a matched stored biometric modality template with the biometric modality template when the biometric modality template is qualitatively better than the matched stored biometric modality template, performing stability accounting when the matched stored biometric modality template is at least qualitatively equal to the biometric modality template, and initiating access processing when at least all biometric modalities are stable and verified.
Core Innovation
A method for seamless biometric self-enrollment is provided in which a user presents a user trusted credential for access to a resource during an enrollment process, and the user trusted credential enables access to the resource while enrolling the user. During the enrollment process, a biometric capture device captures biometric modality data and the enrollment process uses the captured biometric modality data to generate a biometric modality that the user can use to access the resource when the biometric modality is stable.
During the enrollment process, the system determines whether one or more biometric modalities for the user are stable. For each unstable biometric modality, a biometric modality template is generated from the captured biometric modality data, and a matched stored biometric modality template is replaced when the quality score of the biometric modality template is greater than the quality score of the matched stored biometric modality template, where both quality scores are based on quality metrics associated with at least one biometric feature of the biometric modality.
Stability is managed by performing at least one stability process during the enrollment process when the quality score of the biometric modality template is greater than or equal to the quality score of the matched stored biometric modality template, and by repeating capturing, determining, generating, replacing, and performing at each subsequent encounter during the enrollment process. The enrollment process continues until a termination event occurs, and access is granted with a biometric modality independent of the user trusted credential when a matched stored biometric modality template is stable and verified, wherein stability indicates that the matched stored biometric modality template has not been replaced by a new biometric modality template for a defined number of access attempts and the at least one stability process determines the stability of the matched stored biometric modality template.
Claims Coverage
The partial content includes two independent claims: a method for seamless biometric self-enrollment and an access system configured to perform that method. The inventive features are centered on trusted-credential-enabled enrollment, stability determination for biometric modalities, quality-score-based template replacement, stability processing when quality is equal or greater, repetition across encounters until termination, and transition to biometric-only access when a stable and verified matched stored template exists.
Seamless biometric self-enrollment with trusted-credential-enabled access
Capturing biometric modality data in response to presentation of a user trusted credential during an enrollment process, where the user trusted credential enables access to the resource while enrolling the user and the captured biometric modality data is used to generate a biometric modality usable for access when the biometric modality is stable.
Biometric modality stability determination during enrollment
Determining during the enrollment process whether one or more biometric modalities for the user are stable.
Unstable-modality template generation and quality-score replacement
Generating during the enrollment process a biometric modality template from captured biometric modality data for each unstable biometric modality and replacing, during the enrollment process, a matched stored biometric modality template with the biometric modality template when a first quality score of the biometric modality template is greater than a second quality score of the matched stored biometric modality template, where both quality scores are based on quality metrics associated with at least one biometric feature of the biometric modality.
Stability processing when quality is equal or greater
Performing during the enrollment process at least one stability process when the second quality score is greater than or equal to the first quality score, where the at least one stability process determines stability of the matched stored biometric modality template.
Repeated enrollment encounters and transition to biometric-only access
Repeating the capturing, the determining, the generating, the replacing, and the performing when the user attempts to access the resource by presenting the user trusted credential at each subsequent encounter during the enrollment process until a termination event occurs, and granting access with a biometric modality independent of the user trusted credential when a matched stored biometric modality template for the biometric modality is stable and verified.
Stable template definition based on unreplaced behavior over a defined number of access attempts
Defining that stability indicates that a matched stored biometric modality template has not been replaced by a new biometric modality template for a defined number of access attempts by the user.
Access system with trusted-credential enrollment and automated stable-template access
Providing an access system including a biometric capture device configured to capture biometric modality data from a user presenting a trusted credential during an enrollment process, a memory configured to store at least the biometric modality data, a biometric recognition device configured to automatically generate biometric modality templates for each unstable biometric modality, and an enrollment system configured to determine stability, replace matched stored templates based on quality score, perform stability processing when quality is greater than or equal, repeat enrollment actions at subsequent encounters while a template is unstable, and initiate access processing with a biometric modality in lieu of the trusted credential when a matched stored biometric modality template is stable and verified.
Stability indicates an unreplaced stored template over a defined number of encounters
Stating that stable refers to a stored biometric modality template which has been unreplaced by a new biometric modality template for a defined number of encounters.
Across the independent claims, the core coverage is a seamless enrollment process that uses a trusted credential to enable access while capturing biometric modality data, determines biometric modality stability, uses quality scores to replace matched stored templates for unstable modalities, performs stability processes when quality is equal or greater, repeats across encounters until termination, and transitions to access independent of the trusted credential when a matched stored biometric modality template is stable and verified.
