On this page, you will find links to tools that can help improve your privacy on the Internet. With respect to fingerprinting, the best solutions that exist today are to simply block tracking scripts. We cannot recommend spoofers because there is a risk that fingerprinters can detect such spoofing techniques quite easily, which would quickly identify you as a liar. Because the number of spoofers is likely low, your other discriminating data (e.g. fonts and plugins) should be more than sufficient to fingerprint and track you.

Search engine, browser and operating systems

DuckDuckGo - Official webpage
"The search engine that doesnt track you." Launched in 2008, DuckDuckGo differentiates itself from other search engines by emphasizing the protection of searchers privacy and avoiding the filter bubble of personalized search results. DuckDuckGo does not collect or share personal information.

Tor and the Tor browser - Official webpage
The Tor network is a group of servers aimed at improving users anonymity by routing all their traffic through a dedicated network. The Tor browser is based on Firefox and it uses the Tor network. It has been heavily modified to limit as most as possible known fingerprinting techniques so that users share a unique fingerprint (even if in practice, the reality is a little bit different).

Tails - Official webpage
Based around the Tor browser and the Tor network, Tails (The Amnesic Incognito Live System) goes a step further by providing the exact same environment to its users. The operating system has been heavily modified so that it does not leave a single trace on the computer. With the Tor browser, these are the strongest tools against fingerprinting at the price of a decline in usability.

TrackOFF - Official webpage
TrackOFF, a Baltimore-based startup, has launched in mid-2015 a software suite that detects threats and changes your browser fingerprint to improve your digital privacy. Running on Windows for Chrome and Firefox, a trial is available to test this new service.

IP address

Contrary to what people may think, modifying the IP address has no impact on fingerprinting since no addresses are collected to form your fingerprint. Your computer can still be identified and tracked on several browsing sessions. On its own, the IP address is still a really strong form of identification since it may hardly vary over time depending on your internet service provider. Modifying your IP address is a good way to cover your tracks and hide your true location when you are browsing the web.
The most widespread way to change your IP address is to use a VPN (Virtual Private Network) service that will route securely all your network traffic through a trusted server. The Best VPN website has a rich list of VPN providers with detailed reviews about their strengths and weaknesses.


Cookies can be used in addition to fingerprinting to track users on the web and identify with ease returning visitors. One way to counter unwanted tracking is to either limit authorized cookies or block cookies altogether. One recommended setting is to never accept cookies from third-party sites since it is one of the main way for advertisers to track you. You will find instructions on how to block them on Firefox and Chrome.
For the more privacy conscious users among us, you can completely block them in the browser settings ( Firefox or Chrome) or use an extension like Self-Destructing Cookies as mentioned in the browser extensions section. The only downside to these techniques is that you have to whitelist sites if you still want to authorize cookies on some on them.
