Abstract
Biometric authentication of a subject utilizing bone and/or blood vessel (vein or artery) structures is provided. A vertice profile is generated from a non-invasive, multi-dimensional image scan of a subject or a portion thereof. The vertice profile is generated by identifying relative locations of divots and peaks on a surface of a bone structure or by identifying branch intersections and traversals of blood vessels. Additional verification techniques can be used for proof of life (verification of human subject). If authenticated, access to physical or digital/virtual assets is allowed.
Core Innovation
The invention relates to biometric authentication for granting access to a user over a data communication network. A non-invasive anatomical multi-dimensional image is scanned of a human body part using a scanning device of a first biometric device, and a vertice profile is generated. The vertice profile provides relative locations of divots and peaks of a bone structure and is transmitted to an authentication server.
The authentication server generates a vertice profile from the relative locations of divots and peaks of the bone structure and compares the generated vertice profile with a database stored vertice profile. Access is granted only when the comparison meets a pre-determined threshold of accuracy. The access grant is responsive to the determination and is based on a particular level of permissions associated with a user policy.
The document also describes optional proof-of-life using thermal profile and thermal characteristics from a second biometric device and thermal data transmission, including temperature maps. Additional optional aspects include light transducer tuning and prediction of anatomical changes to improve matching. The document includes system and method overviews for authentication and verification using an authentication server and point-of-authentication devices, such as a smartphone and a full body scanner, with example secure access assets including digital, virtual, and physical assets.
Claims Coverage
The partial content provides one independent claim. The claim focuses on granting network access using biometric authentication enhanced with non-invasive bone structure matching, based on a vertice profile derived from anatomical multi-dimensional image scans and compared against a stored vertice profile with a predetermined accuracy threshold, with the resulting access constrained by user-policy permissions.
Network access grant using authenticated vertice profile
Granting an access request to a user over a data communication network through an authentication server based on a particular level of permissions associated with a user policy, responsive to an accuracy-threshold determination.
Non-invasive bone structure matching from anatomical multi-dimensional imaging
Receiving a vertice profile generated from an anatomical multi-dimensional image scanned of a human body part by a scanning device of a first biometric device, wherein the vertice profile provides relative locations of divots and peaks of the bone structure.
Vertice profile comparison to database stored vertice profile
Generating, via a processor and memory of the authentication server, a vertice profile from the relative locations of divots and peaks of the bone structure and determining, via the processor and memory of the authentication server, if the generated vertice profile and a database stored vertice profile, through comparison, meets a pre-determined threshold of accuracy.
Across the independent claim, biometric authentication is enhanced by deriving a vertice profile from non-invasive bone structure matching, comparing it to a database stored vertice profile for a predetermined accuracy threshold, and granting access according to user-policy-based permissions.
Stated Advantages
Improved matching for biometric authentication by using a vertice profile based on relative locations of divots and peaks of the bone structure.
Access is granted only when the generated vertice profile and a database stored vertice profile meet a pre-determined threshold of accuracy.
Access control is refined by granting access based on a particular level of permissions associated with a user policy.
Optional proof-of-life using thermal profile and thermal characteristics from a second biometric device.
Documented Applications
Authentication and verification for granting access to a user over a data communication network using an authentication server and point-of-authentication devices such as a smartphone and a full body scanner.
Secure access to assets including digital, virtual, and physical assets, and an online financial account server.
