This will be my 2nd consecutive year for gsoc participation. Previous mediawiki. Project:BUB tool <http://tools.wmflabs.org/bub/> I stumbled across Panopticlick related project <https://www.torproject.org/getinvolved/volunteer.html.en#Panopticlick> in tor project ideas. I would like to propose a project relating to this. Panopticlick obtains browser fingerprints mainly via javascript objects(navigator, screen, window etc.) These objects are easy to fake in webkit browsers, without touching the underlying source code of browsers, eg. using *__defineGetter__() *after every* javascriptObjectCleared.* If we could compile a large dataset of possible values of js object for several popular browsers, we could use that to randomize the fingerprint for each network request. The dataset could also contain random http header values etc. I am building a python library that does somewhat similar. https://github.com/rohit-dua/selkie (*in development*) It uses pyqt for headless browsing/scraping of webpages. It is a python library that mimics different browser fingerprints by faking(randomizing) the values of navigator, screen object, headers etc. I also intend to add biometric library that mimics humans mouse movements/ keypress statistics for clicking links and surfing pages. I propose to build a similar headless bot that mimics several browsers fingerprints and could be used for anonymous scraping of data and/or adding a feature of random fingerprint in awesome tor tools. Also to improve anonymity location based datasets could be provided(*supported in the above library*) as extra/feature.(maybe downloaded from statcounter.com) Thanks Rohit Dua IRC:rohit-dua github: rohit-dua <https://github.com/rohit-dua/> (8ohit.dua@gmail.com)
