Constant Summary

VERSION =

'0.0.2'

MAX_ALLOWED_DEVIATION =

Number of milliseconds allowed to be slower or faster from measured profile. For example, setting this to 1000 means that there can be a total of 1 second deviation in keystroke min/max/mean seeks and holds combined. Having a 1 second deviation would then make the compare_metrics function return 0. This number needs to be increased as the number of compared metrics increases to allow for standard deviation.

800

PH_FILE =

Password hashes file.

File.join(File.dirname(__FILE__), "../passwd")

KSD_DIR =

Keystrokes dynamics dir.

File.join(File.dirname(__FILE__), "../keystroke_dynamics")

ACCURACY_THRESHOLD =

An accuracy threshold of 0 allows for maximum deviation from measured mean/min/max seek and hold times. An accuracy threshold of 0.5 allows for half of total deviation from measured mean/min/max seek and hold times. An accuracy threshold of 1 allows for 0 milliseconds of total deviation from measured mean/min/max seek and hold times.

0.5
