I wanted to ask if other internet users at the library who are simultaneously using a computer, could be able to see the webpages which some other user is visiting? In other words, how "safe" or "private" is it to use internet in public libraries?
The only way other users can see the web page you are visiting is to actually look at it with their own eyes.
This, unfortunately, is something that does happen. I work at the library but use the public computers quite often, as I haven't got internet access at home. I've been aware of the problem since the shocking moment I realized the guy at the next computer was reading my email. (Can't understand why he found it so interesting.) If you're worried about data security, choose your computer carefully and keep an eye on who is standing behind you, too.
Otherwise it's safer to use the internet at a public library - at least in Helsinki - than to use an online bank, says the PC advisor of our branch. The Helsinki City Library uses 128-bit encryption to protect your privacy, whereas online banks use 64-bit encryption.
The person who reserves the computer after you won't be able to see which pages you've visited. When you finish your session and log out, the desktop is automatically cleared out.
