keystroke_dynamics

DESCRIPTION:

Simple keystroke dynamics analyzer/validator written in Ruby-GTK

FEATURES:

  • Analysis holds logic to extract simple biometric information from GTK widgets.

  • Validation holds logic to manage user enrollment, validation and cryptographic functions.

EXAMPLES:

The three included Ruby-GTK examples demonstrate the principle of biometric authentication based on keystroke dynamics. For experimentational purposes, I have created two different examples which establish a metric from a users typing. The first, enroll_sentences.rb, lets you type in 5 pangrams (sentences that hold every letter of the alphabet) to establish your metric. The other, enroll_login.rb, lets you type your login details 10 times. I leave it as an excercise to the user to see which method works best for him or her. The login.rb example lets you try out your newly created username, password and keystroke metric on a login screen.

REQUIREMENTS:

Depends on

  • GTK

  • Ruby GTK bindings

  • Ruby OpenSSL bindings

INSTALL:

  • sudo gem install ksd

If you don’t have the Ruby GTK or OpenSSL bindings you should install them through your package manager.

On Debian/Ubuntu:

  • sudo apt-get install libgtk2-ruby

  • sudo apt-get install libopenssl-ruby
