L. F. Coppenrath & Associates PASSWORD BIOPASSWORD ® “Fist of the Sender” During WWII The Army Signal Corps Identified Individual Keying Rhythm As Unique. So ‘Senders’ Could be Identified by Rhythm, Pace, and Syncopation of Taps. Reconfirmed by NSF and NBS in the 1980’s When They Determined Typing Patterns have Unique Distinctive Characteristics. “Keystroke Dynamics”

L. F. Coppenrath & Associates PASSWORD BIOPASSWORD ® Unique Statistics To illustrate the unique statistics of keystroke dynamics, the following formula may be used: If "P" equals.01% or.0001 then the following table shows the tries vs. the probability of a security breach based on the binomial distribution of P=.001.

L. F. Coppenrath & Associates PASSWORD BIOPASSWORD ® Security Breach Scenario The proper design of a keystroke dynamics security system can provide additional deterrents to an impostor. An example of the effectiveness of a keystroke dynamics device can be assessed using the following assumption: Every 6 attempts result in a probability of 1 in.0006 of successful access or 6 times in 10,000 tries! The system locks for 5 minutes every sixth try, or must be released by the system administrator. The system would be locked for (10,000/6) x 5 minutes or approximately 140 Hours before a successful keystroke dynamics match. BIOPASSWORD® is Certainly a Deterrent.
