Authentication is a fundamental trust to any trust oriented computational frameworks and furthermore a basic part in numerous security protocols. This paper gives other option to conventional security inquires and OTP. They are attractive since people usually remember pictures. In this paper, we propose a sample sequence of pictorial authentication system and detriments in using OTP. Authentication...
In this study we have tested the hypothesis regarding the increase in synchronization with the onset of muscle fatigue. For this aim, we have investigated the difference in the synchronicity between high density surface electromyogram (sEMG) channels of the rested muscles and when at the limit of endurance. Synchronization was measured by computing and normalizing the mutual information between the...
The tools used for assessment of rotor angle stability should be able to estimate the domain of attraction and the ensuing control laws which would aid in enhancing it. The widely used energy function formulations have limitations in being extended for lossy N-machines owing to the presence of transfer conductances obtained due to the modeling approaches used in transient stability studies. This problem...
Changes in surface electromyogram (sEMG) spectral content are commonly associated with localized muscle fatigue. However, the significance of the changes is only evident during pair-wise comparison and these can only be used for comparison between the rested and fatigued muscle and cannot be used for identifying the limit of muscle endurance without having the rested data for comparison. This is due...
In this work, we study the problem of detecting audio-visual (AV) synchronization in video segments containing a speaker in frontal head pose. The problem holds important applications in biometrics, for example spoofing detection, and it constitutes an important step in AV segmentation necessary for deriving AV fingerprints in multimodal speaker recognition. To attack the problem, we propose a time-evolution...
