Acoustic attack on keyboards

Usage

  1. Run tempest.py -train and record a training set. It has to be quite large to be able to classify keystrokes. For a good result:

    1. Push each key several times.
    2. Do not push the keys too frequently.

  2. Run tempest.py and record a test set.

  3. To start the support vector machine classifer and get the results, run svm.py.

Based on the code here.
