Some other tricks you can use to identify someone.
Use code in websites that will trigger reported bugs. If bug action isnt detected, then browser could be masquerading as some other browser.
Where bug is known to have impact on OS, again depending on action, could indicate unpatched system ready for exploits, how many of those are there in the world?
Considering the vague geolocation Google and other location services put you at if you were to search for a plumber (see Google maps with plumbers pinpointed on the map for you) and what the ISP will do to obfuscate your location, you have to ask yourself some of the following questions.
When you break down how many people live in this obfuscated area, how many people who at that moment in time will be away from a computer doing a job not involving a computer?
How many people will be at work on a computer?
How many people will be driving?
How many people will be shopping?
How many people will be asleep due to working shifts?
How many people will be waiting in hospital?
How many people will be doing other activities not involving web browsing?
How many people always check out the same few websites out of the billions available to choose from?
How many people who will be carrying their mobile phone around with them placing them in a location already, with various phone OS sniffing wifi if GPS cant be seen.
Do you really believe your mobile phone software when it says you have switched off wifi & gps?
Did you write the software or just naively believe the programmers say even though some have admitted you are the product?
When you take all of the above into consideration, you cant have privacy, in fact your interests and repeat behaviour visiting the same websites, at the same or similar times of day having specific interests give you away over and over and over again.
The military like to call this Signals Intelligence (or SigInt), businesses call this data analysis amongst other names made up by some executive who thinks they can coin a new term or phrase, and one way or another you work or support those big corporates who own your Govt and feel its their right, their duty to spy on you monitoring your work performance and your private life whether you like it or not, to extract the maximum out of money out of your slave wages whilst giving you less and less back.
If your favourite search engine keeps giving you the same few shopping outlets, and you keep being giving a limited choice of products and services to choose regardless of how you phrase your search results, then that search engine has already worked out who you are and they are now controlling your life by what they choose to show you.
Enjoy your life slave, you slept walked into that one didnt you?!?
