    摘要: A biometric feature detection system is provided according to one embodiment. The system may include a target, an illumination source, a color filter array, a light detector, and a computational unit. The illumination source illuminates a portion of the target with monochromatic light at a large angle of incidence measured from the normal of the target surface. The light detector may be configured to receive light from the target through the color-filter array and provide an image of the target surface. Each pixel of the light detector may correspond to one of a plurality of color filter mosaics such that each pixel detects light associated with a corresponding color filter. The computational unit may be interfaced with at least the light detector. The computational unit may include instructions to monitor the levels of monochromatic light and make proximity, presence and segmentation determinations based on the detected levels of monochromatic light.

    摘要: Embodiments of the invention provide for a biometric system with an optically adaptive interface. In some embodiments, an optically adaptive interface changes optical characteristics in response to the placement of a finger on the optically adaptive interface. In some embodiments, the optically adaptive interface can include an active layer and a surface layer. The active layer and the surface layer can have different optical properties. For example, one layer may be opaque and the other transparent, the two layers may have complementary colors, the two layers may have orthogonal polarization reflectors, one layer may be reflective and the other absorptive, etc. Moreover, the active layer can be a fluid with either high or low viscosity. For example, the viscosity can be such that the active layer fluid is either completely displaced or not displaced in locations corresponding to finger valleys.

    摘要: Methods and apparatuses for performing biometric determinations using optical spectroscopy of tissue. The biometric determinations that are disclosed include determination or verifications of identity, estimation of age, estimation of sex, determination of sample liveness and sample authenticity. The apparatuses disclosed are based upon discrete light sources such as light emitting diodes, laser diodes, vertical cavity surface emitting lasers, and broadband sources with multiple narrow-band optical filters. The multiple light sources are encoded in a manner that the tissue response for each source can be efficiently measured. The light sources are spaced at multiple distances from a detector to contribute differing information to the biometric determination task as do light sources with different wavelength characteristics. Apparatuses are disclosed that incorporate a spectral biometric sensor with a personal electronic device such as cellular telephones, personal digital assistants, wristwatches, electronic fobs for the purpose of providing secure biometric access to protected property.
