Abstract: Provided is a method of detecting fraud during use of a device for capturing an imprint of a body part using a principle of total internal reflection with dark field and including a transparent plate on which a body part to be verified is placed. The method includes: using the device to acquire a first imprint image with a lighting of the body part such that the whole surface of the body part in contact with the transparent plate returns light; using the device to acquire a least one second imprint image by illuminating the body part with a single LED; obtaining for each second imprint image an item of information representative of a light level re-emitted by the body part by using each image obtained; and comparing each item of information obtained with a reference item of information to validate that the body part is a true body part.

Abstract: Systems and methods are described for providing reliable biometric access control using an optical biometric sensor in a miniaturized form factor. Some implementations include multiple light sources that can illuminate skin or other tissue at multiple locations during a single measurement session. An imaging array can be arranged to form images of the light exiting the tissue only after undergoing diffuse reflectance in the tissue. Some implementations use the images to perform biometric functions. For example, the images can be used to identify an individual, verify identity of an individual, estimate demographic characteristics of an individual, etc. Such biometric functions can further be used to determine and affect access to secured assets.

Abstract: An optical sensing device can receive a speckle pattern generated by a laser's interaction with acoustically stimulated tissue. A computing device can identify one or more characteristics within the received speckle pattern. The computing device can then identify a match of the one or more characteristics to a user biometric signature stored within a storage device. Based upon the identified match, the system can authenticate a user within a computer system.

Abstract: A method using optical coherence tomography to capture the microvascular network of the superficial layer of the finger skin for the purpose of fingerprint authentication and liveness detection. At the dermal papilla region, the vascular pattern follows the same pattern of the fingerprint and this vascular pattern forms a live vascular fingerprint. This live vascular fingerprint provides for ultrahigh security and a unique way for fingerprint-based personal verification. Because the system is based on blood flow, which only exists in a living person, the technique is robust against spoof attaching. After performing non-contact in-vivo imaging of a human fingertip, a three dimensional vasculature image is reconstructed from a plurality of vasculature tomography images and at least one vasculature fingerprint image which corresponds to the fingertip is extracted from the three dimensional vasculature image. This extracted image may then be compared to known fingerprint database for authentication or for liveness detection.

Abstract: An electronic device and fingerprint recognition method are provided. The electronic device includes a housing, a lens protection cover, a processing unit, an image capturing unit, a light-source sensor and a visible light source module. The lens protection cover is installed on the housing. The light-source sensor is configured to detect external light which comes into the electronic device through the lens protection cover. The processing unit determines whether the detected external light is less than a threshold. The visible light source module is configured to generate visible light. When the detected external light is less than the threshold, the processing unit activates the visible light source module to generate the visible light, and activates the image capturing unit to capture a fingerprint image of a user's finger which is put on the lens protection cover for fingerprint recognition.
