Bad Sounds Good Sounds: Attacking and Defending Tap-Based Rhythmic Passwords Using Acoustic Signals
Tapping-based rhythmic passwords have recently been proposed for the purpose of user authentication and device pairing. They offer a usability advantage over traditional passwords in that memorizing and recalling rhythms is believed to be an easier task for human users. Such passwords might also be harder to guess, thus possibly providing higher security. Given these potentially unique advantag...
متن کاملAudible pedestrian traffic signals: Part 2. Analysis of sounds emitted.
This project evaluated audible pedestrian traffic signals from three perspectives: 1) the patterns of use and the impact of these signals on pedestrian travel; 2) the physical characteristics of the sound emitted by these devices; and, 3) the detection of their emitted sounds in the presence of various traffic noise levels. This paper, the second of three companion articles (2, 3), examines the...
متن کاملAutomatic classification of normal and abnormal cardiac sounds by combining features based on wavelet transform and capstral coefficients extracted from PCG signals (Research Article)
Cardiac sounds are produced by the mechanical activities of the heart and provide useful information about the function of the heart valves. Due to the transient and unstable nature of the heart's sound and the limitation of the human hearing system, it is difficult to categorize heart sound signals based on what is heard from a stethoscope. Therefore, providing an automated algorithm for prima...
متن کاملInfluence of imaged pictures and sounds on detection of visual and auditory signals.
The present study compared sensitivity for auditory and visual signals in a simple detection task and in a related task in which ,9 was also imaging mental pictures and sounds. Sensitivity (rf') was reduced during imagery; within the imaging conditions, it was smaller when image and signal were both auditory or both visual than for cross-modal conditions and smaller with unfamiliar than familia...
متن کاملSounds and beyond: multisensory and other non-auditory signals in the inferior colliculus
The inferior colliculus (IC) is a major processing center situated mid-way along both the ascending and descending auditory pathways of the brain stem. Although it is fundamentally an auditory area, the IC also receives anatomical input from non-auditory sources. Neurophysiological studies corroborate that non-auditory stimuli can modulate auditory processing in the IC and even elicit responses...
