  reference: <a href="http://valve.github.io/fingerprintjs/" rel="nofollow">http://valve.github.io/fingerprintjs/</a></p>
  
  <p>It works fine and generate same code every time i use a particular page. But when the same code and page is executed on private mode of the same browser it generates different code.</p>
  
  <pre><code>var fingerprint = new Fingerprint({
                         ie_activex: true,
                         screen_resolution: true,
                         canvas: true}).get();
  console.log(fingerprint);
  </code></pre>
  
  <p>What should i do to make it same on private mode.</p>
