This is +because any approach we take to reduce fingerprinting automatically makes our +users more distinct from the previous users who submitted their fingerprint +data to the EFF. Indeed, it is also impossible to ever expect that users of +one browser will ever be able to blend in with users of another browser +(Chrome users will always be distinguishable from Firefox users for example, +based on feature set alone). + + </p> + <p> + +To address this, we would like to have <a +href="https://trac.torproject.org/projects/tor/ticket/6119">our own +fingerprint test suite</a> to evaluate the fingerprintability of each browser +feature for users running a specific Tor Browser version. There are also <a +href="https://trac.torproject.org/projects/tor/query?keywords=~tbb-fingerprinting">additional +fingerprinting tests</a> we can add beyond those deployed by Panopticlick. + </p> + <p> + +For this project, the student would develop a website that users can +voluntarily visit to test and record their Tor Browser fingerprint. The user +should get feedback on how she performed and the test results should be +available in a machine readable format (e.g. JSON), broken down by Tor Browser +version. In a second step one could think about adding more sophisticated +tests or supporting other browser vendors that might want to test the +uniformity amongst their userbase as well. Of course, results from each +browser would also need to be broken down by both browser implementation and +version, so that results would only reflect the population of that specific +implementation. + + </p> + </li> + <!-- <a id=""></a> <li>
