Classification: G06F

Abstract:
1. A method for providing computer-based authentication utilizing absolute keystroke timing biometrics, the method comprising the acts of: obtaining a first absolute keystroke timing data of a user while the user types a passphrase; responsive to said obtained absolute keystroke timing data, analyzing and abstracting the absolute keystroke timing data into a keystroke timing data template; obtaining a second and subsequent absolute keystroke timing data of a user while the user types a passphrase and responsive to said received second and subsequent absolute keystroke timing data, merging said second and subsequent absolute keystroke timing data with said keystroke timing data template to create an updated, merged keystroke timing data template; verifying said second and subsequent absolute keystroke timing data against said updated, merged keystroke timing data template; and performing nonce profiling of the absolute keystroke timing data and the second and subsequent absolute keystroke timing data and configuring the nonce profiling into a new passphrase.
