Keystroke detection example code

The following is an example of the implementation of keystroke dynamics based on the dataset described in the study Comparing anomaly-detection for keystroke dynamics mentioned in the previous section; the dataset is also available for download in .csv format at https://www.cs.cmu.edu/~keystroke/DSL-StrongPasswordData.csv.

As anticipated, the dataset consists of 51 subjects, each typing 400 passwords; also among the measures collected are these hold times (represented in the dataset with the label H):

• Keydown-keydown time (labeled as DD)
• Keyup-keydown time (labeled as UD)

The code for the keystrokes detection script is as follows:
