In our extensive experimental evaluation, we achieved an accuracy of \(97\%\).
Moreover, we made the software of the Proof-of-Concept available, as well as the datasets used to evaluate it. Then, we discuss a Proof-of-Concept, implementing the methodology, that shows how the attack can be performed in practice and allows to assess the deanonymization accuracy that it is possible to achieve. For this purpose, we describe a general methodology for performing an attack that allows to deanonymize the apps running on a target smartphone using Tor. While attacks against Tor anonymity have already gained considerable attention in the context of website fingerprinting in desktop environments, to the best of our knowledge this is the first work that addresses a similar problem on Android devices. The aim of this work is showing that Tor is vulnerable to app deanonymization attacks on Android devices through network traffic analysis. For this reason they are continuously under deep observation to detect vulnerabilities that would compromise users anonymity. Solutions like Tor allow users to gain more freedom, bypassing these restrictions. More often than not you have nothing to hide, but even so, valuing and protecting your right to privacy and anonymity on the net is paramount to freedom.According to Freedom on the Net 2017 report more than 60% of World’s Internet users are not completely free from censorship. Tor Browser is a powerful and, above all, secure Internet browser that lets you surf anonymously. In that sense, you gain total anonymity and total browsing freedom. In other words, if a person or website tries to find out who you really are or what website you're using, the only thing they'll see is that you're logging on from the Tor network. In that sense, using Tor is completely unlike other browsers, where after looking for information about shoes on a page, you'll get ads trying to sell you shoes on the next page you visit.Īnother advantage of Tor Browser is that all its users seem to have the same appearance when it comes to any monitoring system attempt. Any time you leave a page, your cookies are automatically cleaned. One of the most interesting (and popular) features of Tor Browser is the ability to isolate every web page you visit, so trackers and ads can't follow you from one web page to another. Orbot, as many users already know, is a version of the Tor network for Android-one of the most powerful Internet privacy tools out there today. Now you can surf the Internet completely anonymously and securely, hiding your online identity under several layers of security. Tor Browser is the official browser for Tor Project, the team behind Orbot.
