摘要： Methods and systems of determining whether an object is alive, and therefore part of a live individual, are described. An object having an outer surface (e.g. a friction-ridge surface of a finger) and internal parts (e.g. tissue layer, papillae, blood vessels, fat, muscle, nail and bone) is scanned by a system having a transmitter, receiver and computer. One such system has a substantially planar piezoelectric transmit-layer, an ultrasonic receiver array having a plurality of receivers, and a platen. The transmit layer is caused to produce an ultrasound plane-wave traveling toward the object residing on the platen. Using the ultrasonic receiver, ultrasonic energy that has been reflected from the object is detected. The detected ultrasonic energy is analyzed to provide an analysis result, and the analysis result is compared to a template. A determination is made as to whether the analysis result and the template are similar, and the object is declared to be alive if the analysis result is determined to be similar to the template.

摘要： System and techniques for spoofing detection in image biometrics are described herein. A sequence of images may be obtained from a camera; a first plurality of images in the sequence of images including a representation of a user body part, and a second plurality of images in the sequence of images including a representation of an environment of the user. A marker may be created for the representation of the body part. A feature of the environment of the user present during the second plurality of images may be identified in the sequence of images using a third group of circuits. A correlation between the marker and the feature of the environment in the sequence of images may be quantified to produce a synchronicity metric of the degree to which the marker and the feature of the environment correlate.

摘要： A device for adjusting a brightness of a display is provided. The device comprises means configured for receiving images from a digital camera, detecting an eye of a viewer in a current camera image, determining an intensity of a reflection of the display by the eye, and adjusting the brightness of the display based on the intensity of the reflection. Thereby, the brightness is adjusted based on the intensity of light which is emitted by the display and which actually is received by the eyes of the viewer. Further, a method of adjusting a brightness of a display, a corresponding computer program, and a corresponding computer program product, are provided.

摘要： A method for detecting user head motion during an authentication transaction that includes generating, by a processor, a motion type feature vector and a user head motion type prediction based on data generated for a sequence of frames that are included in biometric data captured from a user. The method further includes generating a liveness rating feature vector based on the generated frame data, merging the motion type and liveness rating vectors, and generating a spoof prediction from the merged vector. When the generated spoof prediction indicates that biometric data in the frames were spoofed, the user head motion type prediction is changed to no motion. The method also includes storing the user head motion type prediction in a buffer, and determining a final user head motion type detected for the frames.
