Abstract: Systems and methods for biometric authentication are disclosed. The invention may be used to authenticate an individual. At least two enrollment templates may be obtained at different times. Later, an inquiry template may be obtained and compared to each of the enrollment templates in separate and distinct comparison operations. The match scores arising from the comparison operations may be fused to provide a composite match score. The composite match score may be compared to an acceptance range. If the composite match score is within the acceptance range, the individual may be authenticated.

Abstract: A method is disclosed, including detecting a signal representative of an object with a piezoelectric device. A display is powered up from a sleep mode based upon the detected signal. The display can be powered up based upon a comparison of the signal to a threshold value. The threshold value can be a predetermined value or based upon a previous signal detected by the piezoelectric device or a previous signal detected by the piezoelectric device.

Abstract: The described techniques support a sensing scheme for electromagnetic excitation in ultrasonic imaging sensors. A biological tissue may be sensed and imaged using an electromagnetic excitation process to generate ultrasonic waves, such as, within the tissue. A component of a device may generate one or more pulses of electromagnetic waves, which may encounter and enter the biological tissue. The electromagnetic waves may excite the biological tissue and generate ultrasonic waves via expansion and contraction of the tissue upon heating. The ultrasonic waves may propagate within the biological tissue and may be sensed by an ultrasonic receiver array. The ultrasonic waves may be converted to pixel image data of a biometric image and may be used for biometric authentication. This process may be repeated to reconstruct an image of the finger at multiple plane slices of the finger.

Abstract: An apparatus may include an ultrasonic sensor array and a control system. The control system may be configured to acquire first image data generated by the ultrasonic sensor array corresponding to at least one first reflected ultrasonic wave received by at least a portion of the ultrasonic sensor array from a target object during a first acquisition time window. The control system may be configured to acquire second image data generated by the ultrasonic sensor array corresponding to at least one second reflected ultrasonic wave received by at least a portion of the ultrasonic sensor array from the target object during a second acquisition time window that is longer than the first acquisition time window. The control system may further be configured to initiate an authentication process based on the first image data and the second image data.

A biological tissue may be sensed and imaged using an electromagnetic excitation process to generate ultrasonic waves, such as, within the tissue. A component of a device may generate one or more pulses of electromagnetic waves, which may encounter and enter the biological tissue. In some examples, the component may be a display interface or may be different from a display interface of the device. The electromagnetic waves may excite the biological tissue and generate ultrasonic waves via expansion and contraction of the tissue upon heating. The ultrasonic waves may propagate within the biological tissue and may be sensed by an ultrasonic receiver array. The sensed ultrasonic waves may be converted to pixel image data of a biometric image and may be used for biometric authentication.

Abstract: A subdermal imaging system which may determine whether a person's body is in contact with a display, and perform a subdermal imaging process to determine subdermal characteristics by a photoacoustic imaging process. Ultrasonic emissions emitted from the photoacoustic process may be received with an ultrasonic receiver array. The subdermal imaging system may adjust the wavelength and/or intensity of the photoacoustic process in order to image desired subdermal features.

Abstract: An apparatus may include an ultrasonic sensor system and a control system. The control system may be configured to distinguish, according to image data acquired via an ultrasonic sensor system, the pyroelectric effect caused by an actual human finger from the pyroelectric effect caused by a sleeve-type spoof or a “fake finger” spoof. Some such examples involve obtaining multiple frames of ultrasonic image data of a target object on or near a platen of an ultrasonic sensor system via the ultrasonic sensor system and determining at least one target object pyroelectric indication based, at least in part, on the multiple frames of ultrasonic image data.

Abstract: Techniques for authenticating a biometric input are disclosed. An example of a biometric authentication system is configured to receive a biometric input, perform a first authentication process on the biometric input with an application processor, such that the first authentication process generates one or more authentication parameters, provide the one or more authentication parameters to a secure processor, perform a second authentication process on the biometric input on the secure processor, such that the second authentication process utilizes the one or more authentication parameters, and output an authentication score based on the second authentication process.

Abstract: Techniques described here use variations in the sensor to generate an identifier for the sensor. Each sensor may be comprised of sub-sensing units, called pixels that may demonstrate variation in their sensing capability from one pixel to another. Embodiments of the invention, describe a method for using the relative variance of each pixel (relative to the whole sensor or/and a portion of the sensor) in generating an identifier for the sensor. In one embodiment, the method may obtain information associated with a plurality of pixels from a sensor, detect variations in the information associated for each of the pixels from a subset of the plurality of pixels and generate an identifier for the sensor using the detected variations in the information associated with each of the pixels from the subset of plurality of pixels.
