Abstract: The biometric system disclosed herein comprises device for providing a pattern; the device having a source of light and a source for providing a pattern. The source of light is operative to illuminate an object with light. An imaging device is disposed at a different location from the source of light to capture an image from the object. The system further comprises a pattern comparison device; the pattern comparison device being operative to compare details of the pattern disposed upon the object and details of a reference pattern; the pattern comparison device rejecting the object if the pattern disposed upon the object does not match the reference pattern.

Abstract: The invention provides a method, system, and program product for transforming a multi-dimensional biometric feature point set. More particularly, the invention provides a method for transforming a biometric image using surface folding of the image. In one embodiment, the invention provides a method for transforming a multi-dimensional biometric feature point set, the method comprising: converting the multi-dimensional biometric feature point set to a canonical position and orientation; applying a non-invertible transform function to each of a plurality of points of the biometric feature point set; and providing a transformed biometric feature point set comprising a plurality of transformed points.

Abstract: The invention provides a method, system, and program product for identifying an individual using biometric data based on the individual's brain. In one embodiment, the invention includes constructing a biometric signature based on at least one of: features within a two-dimensional scan of the individual's brain and a difference in features between at least two two-dimensional scans of the individual's brain.

Abstract: A system and method for multi-party authentication is described. The multi-party authentication process uses synchronous and persistent biometrics signals received from parties to a transaction, based on a policy, to approve a transaction request. The biometrics signals preferably are expressed as compressed video signals having steganographically inserted challenge response data. Several business applications are described that are based on the multi-party authentication engine.

Abstract: A method of doing business is disclosed that transforms a biometric used by a user in a transaction. The transformation creates a distorted biometric. The distorted biometric is used to identify the user to another party without requiring the user to provide actual physical or behavioral characteristics about himself to the other party.

Abstract: This invention uses a novel biometrics, called resultant fingerprints and palm-prints, for authentication. The novel biometrics are consecutive traditional print images where the subject physically changes the appearance of the print images by rotating or rotating and translating, or rotating, translating, and shearing the finger or palm. That is, it is a sequence of finger or palm-print images over a short interval of time where the images are modified according to the rotation or a combination of rotation and translation or a combination of rotation, translation, and shear. The rotational and translational and shear components of the motion in the sequence of print images are determined from the image-to-image flow. This flow is either computed from motion-compensation vectors of the sequence compressed in MPEG formats or directly from the uncompressed images.

Abstract: The present invention combines the functionality of a computer pointing device with a fingerprint authentication system, In the preferred embodiment, by regularly scanning fingerprints acquired from the pointing device touch pad, fingerprint features may be extracted and compared to stored data on authorized users for passive authentication. Furthermore, calculations based upon the acquired fingerprint images and associated features allows the system to determine six degrees of freedom of the finger, allowing the user to control a variety of functions or to manipulate a three-dimensional model or virtual reality system.

Abstract: An integrated signal sensor with processing power to augment a challenge from server and compute the response is proposed to guarantee that the sensed signal is live and not stored. The sensor-processor computes the response to the augmented challenge based on the signal charactersitics of the sensed signal and then transmits both the signal and the response. The host or the server can verify the response to authenticate liveness of the input image/signal and reject it if the response is different. Areas of application include automated biometrics and remote medical imaging.

Abstract: Authentication methods are very important in several applications. Existing methods of authentication based on possessions or knowledge have several problems that can be overcome by using biometrics. Unfortunately biometrics-based authentication is unrevocable today and has many privacy concerns in users' minds. The proposed technique employs signal scrambling and morphing techniques to intentionally distort the original biometrics signal in a non-invertible fashion. If the security is compromised, the system can cancel a particular distortion and reacquire the signal with a new distortion function. This provides functionality as good as non-biometric authentication methods in terms of their power of revocation.
