If you are a little concerned about your privacy and wants to know how much a website or internet knows about you then believe me you will shocked to know the truth. All information supplied by you, your friends, your government and other agencies on internet are collectively enough to publish your biography.
Internet and websites knows your IP Address
The first thing that a website knows about you is your IP address (unique address assigned to your machine that is connected to internet). IP address is a 32bit binary address which can be written as 188.8.131.52 in decimal. If you know IP address of a person you can easily guess their geographical location and ISP (Internet service provider).

What facebook knows about you?
We all have personal accounts and profiles on facebook and other social networking sites and usually we keep most of them updated. All the information that is put onto facebook is not limited to facebook.
Application (or apps) on facebook are third party applications that are developed by individual programmers or IT companies and when you try to access these apps they ask you for your information and with just one click by you allows facebook to give them all the required information. As programmers or companies are bind with the policy of facebook that they should never misuse the info that they get from facebook but what if they do that? We can’t guess what’s happing into others mind.
Also, websites that allows logging with facebook account are also in the list who knows your name, email address, occupation, phone number, date of birth and everything available to them through facebook (your profile, friends name, your favourite and likes, your updates comments etc) with the help of API (application programming interface) released by facebook.
Any information left?
I don’t think there is any information left that isn’t revealed but this is not the only information they can get about you. Actually, with all the information that they have they can get hands on to other info, for instance if they know your email they can search it on social networking websites (LinkedIn, twitter etc) for your profiles and can confirm the details with your date of birth and phone number and may get your residential address and other information.

Why all these information are revealed?
All the information that are being revealed by your computer or its softwares may be a threat to your privacy but all these information should be revealed or generated otherwise you will not be able to connect to Internet because in order to connect to the internet or any other network in the world there are always certain protocols that must be followed by everyone for the purpose of authentication and their safety of each other. If no information is tracked or logged then some malicious peoples can misuse these facilities and can harm you. Thus all the information that is being revealed or logged is ultimately beneficial for you.
Don’t worry and enjoy the web browsing expect if when you are a celebrity or billionaire 🙂 Remember only one thing on the internet –Never ever reveal your very personal details on internet (or email) like bank details, pins and password etc to anyone even if you got an email from your bank or word bank asking for updated information or verification for the purpose of sorting some problem or rewarding you with the 100 billion USD/GBP that you won in a lottery or may be left by your relative.
