Abstract: Disclosed is an apparatus and method for automatically enabling a touchscreen of a mobile device based on detection of the presence of a human finger. A mobile device can capture an image of an object with a fingerprint sensor. The mobile device may then enable a touchscreen display of the mobile device in response to a determination that the object captured within the image is a specific type of object.

Abstract: A method includes accessing signal data descriptive of a transmission sequence and pre-determined values associated with the transmission sequence. The signal data and the pre-determined values may be stored in a memory. The method includes transmitting a signal from a speaker of an electronic device according to the transmission sequence. The method includes generating a frame based on one or more signals received at a microphone of the electronic device. The one or more signals include an echo signal associated with the transmitted signal. The method includes processing the frame using the pre-determined values to produce an output frame in which a contribution associated with the echo signal is reduced.

Abstract: An apparatus and method for device security, wherein a fingerprint image is acquired on a touchscreen, and an authentication process is performed based on the first fingerprint image. Thereafter, a second fingerprint image is acquired and a difference between a characteristic of the first and second fingerprint images is determined, and based upon whether this difference is greater than a threshold, a second authentication process is performed.

Abstract: The disclosure is directed to storing trace information. An aspect includes determining whether or not a pen is within a threshold distance of the touchscreen, storing trace information generated by a user's touch in a touch buffer if the pen is not within the threshold distance of the touchscreen, and clearing the touch buffer and storing trace information generated by the pen in the touch buffer if the pen is within the threshold distance of the touchscreen.
