Latest Patents

Shashi Phoha holds a patent for a method titled "Hidden Markov Model ('HMM')-based user authentication using keystroke dynamics." This patent describes a system where HMMs are utilized to analyze keystroke dynamics measurements collected as a user types a predetermined string on a keyboard. During the enrollment process, a user types the predetermined string multiple times, allowing the HMM to be trained to identify the user accurately. When a candidate claims to be the user, they provide a typing sample, and the HMM calculates the probability of their identity based on the typing dynamics. This method also includes a computationally-efficient approach for preparing HMMs to analyze specific types of processes.
