Abstract: A mobile communication device equipped for proximity detection may include a transmitter that emits a periodic ultrasound signal, a receiver that detects the periodic ultrasound signal, an intra-frame filter that filters the detected periodic ultrasound signal based on a frame length of the detected periodic ultrasound signal, and a detector that determines a power level of the filtered periodic ultrasound signal to detect if the receiver is located in an undesirable location.

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.
