You can try, but you can’t hide online Use private surfing

Hide your IP address

The Tor network

Firefox New tab

Proxy server

End server

New private window

Some browsers, such as Mozilla Firefox, Google Chrome, Internet Explorer and Apple Safari come with a built-in privacy feature. For example surfing in the Firefox private window will not save visited pages,form and search Bar entries, passwords, downloaded file lists, Cookies and temporary Internet files.

A proxy server acts as an intermediary between your computer and the server (or website) you are connecting to. Using an anonymous proxy hides the link between your ip-address and the end server. However, using a proxy does not completely hide your identity, but makes it harder to trace. Information on how to set up a proxy on your browser in WikiHow: wikihow.com/ Surf-the-Web-Anonymously-with-Proxies

The Tor network is a free software and open network that sends encrypted data to and from your computer. Tor routes internet traffic through a worldwide network of volunteer servers. It makes activity on the internet almost untraceable. www.torproject.org

” It’s not possible to hide your traces. Everyone can be found.”



Social media tips


Before creating an account, evaluate the social media website:

Does it offer a sufficient level of control on my privacy? Does the site claim ownership of my media? Does it protect my privacy? Does it give you a good user experience?

Think twice – or even better, three times – before sharing. Remember that once you share something, it’s out of your control. Be careful when you click on links. Don’t click everything.

Be selective about who you accept as your friends. Do not install apps or games if you don’t know what they’re for.



Build up your computer’s defenses (antivirus, anti-spyware, anti-spam and firewall) and keep them up to date. You can also use AdBlock to block advertisement.


If you are a student at the University of Tampere, you can get F-Secure antivirus software for free at the University Intra Web at uta.fi.
