Abstract: A method, system and computer program for categorizing heart diseases is presented. An example method includes receiving a series of cardiac images of a heart, the cardiac images including a myocardium, and interior fibrous muscles of the heart. Cardiac images are segmented, into a myocardium segmentation showing an anatomical shape and a motion of the myocardium, and an interior fibrous muscles segmentation showing an anatomical shape and a motion of the interior fibrous muscles. The myocardium segmentation is converted into a regional characterization of the anatomical shape and motion of the myocardium. The interior fibrous muscles segmentation is converted to a regional characterization of the anatomical shape and motion of the interior fibrous muscles. Heart conditions are characterized based on the regional characterizations of the anatomical shape and the motion of the myocardium and the interior fibrous muscles.

Abstract: One or more processors generate a set of facial appearance parameters that are derived from a first facial image. One or more processors generate a graphics control vector based, at least in part, on the set of facial appearance parameters. One or more processors render a second facial image based on the graphics control vector. One or more processors compare the second facial image to the first image. One or more processors generate an adjusted vector by adjusting one or more parameters of the graphics control vector such that a degree of similarity between the second facial image and the first facial image is increased. The adjusted vector includes a biometric portion. One or more processors generate a first face representation based, at least in part, on the biometric portion of the adjusted vector.

Abstract: Method, apparatus and computer program product compare biometrics in an anonymous manner. A first collection of biometrics is transformed using a first cancelable non-invertible biometric transform to create a first collection of transformed biometrics. A second collection of biometrics is transformed using the first cancelable non-invertible biometric transform to create a second collection of transformed biometrics. The first and second collection of transformed biometrics are then compared in the transformed domain to determine if any of the transformed biometrics from the first collection match any of the transformed biometrics from the second collection. If a match is found, the parties respectively maintaining the first and second collections of biometrics exchange information confidential nature of the biometrics are maintained by the entities responsible for the collections, since the biometrics are not compared in an untransformed state.

Abstract: A system and method for performing an identity search in a database of iris images for a probe iris image includes generating a full-length iris code and a compact iris code for iris images in a database, and generating a full-length iris code and a compact iris code for a probe iris image. The compact iris code for the probe image is scored against all compact iris codes in the database. A fraction of the database is retained based on score data. The full length iris code for the probe image is scored against all the full length iris codes in the retained portion of the database.

Abstract: A system and method for generating compact iris representations based on a database of iris images includes providing full-length iris codes for iris images in a database, where the full-length iris code includes a plurality of portions corresponding to circumferential rings in an associated iris image. Genuine and imposter score distributions are computed for the full-length iris codes, and code portions are identified that have a contribution that provides separation between imposter and genuine distributions relative to a threshold. A correlation between remaining code portions is measured. A subset of code portions having low correlations within the subset is generated to produce a compact iris representation.

Abstract: Methods and systems for remotely enrolling enrollees into biometric databases are provided. The method includes acquiring biometric data from one or more biometric sensors and authenticating an enrollee associated with the biometric data. The method includes enrolling the authenticated enrollee associated with the biometric data. The acquiring occurs externally from equipment that requires an identification. The method includes verifying individual samplings of the biometric data for quality at the time of enrollment based on a pre-determined threshold and verifying whether the enrollee presenting the biometric data is authenticated at the time of enrollment. The method includes signing a request of a third party with a private key associated with the third party, the signing denoting that the biometric data is verified for a transaction between the third party and the enrollee. The method includes sending the signed third party request to the third party to complete authenticating of the transaction.

Abstract: A method and system is provided to provide enrollment of biometric data from individuals without the need for the enrollees to travel to a central location. The system and method provides for optionally detecting multiple types of biometric data, for example, fingerprints, facial scan, visual scan, iris scan, voice scan, or the like, to be captured at the point of enrollee use. During the biometric capture process, the biometric enrollment device monitors and establishes the identity of the enrollee and measures the quality of the biometric input as it occurs. If unacceptable quality is detected, then repeated biometric scans may be necessary, but is done at time of enrollment avoiding any need to send inaccurate information back to a service institution. When the enrollment process completes, the biometric data is encrypted, time stamped and either mailed back to the service institution or is transmitted back.

Abstract: A system and method for generating a cancelable biometric includes shifting at least one pixel region in a biometric image comprised of pixel regions. The at least one pixel region is combined with at least one other pixel region to form a replacement region for the at least one pixel region to form a transformed image. The biometric image is reused to generate another transformed image if the transformed image is to be canceled.

Abstract: A biometric representation of a fingerprint from which the original biometric cannot be recovered (privacy) and which can be canceled and reissued. For example, based on an individual's token, the representation can be scrambled uniquely to the individual. From the scrambled biometric representation it is not feasible to reconstruct the biometric and if the representation is compromised, a new one is easily issued. In another aspect, if a biometric can be represented by some other one-dimensional structure, a distance or similarity measure is defined to compare biometrics. Verification decisions can be made based on the distance between or similarity of biometrics.
