What information can we access from the client? [closed]

I’m trying to compile a list of information that is accessible via javascript such as:

• Geo-location
• IP address
• Browser software
• Exit location
• Entrance location

I understand that a user can alter any of this information and that it’s reliability is purely trust related, but I am still interested in what other information can be mined from the client.

Answer

Don’t forget about

• Screen Size
• Allowed Cookies
• Allowed Java
• Mobile or Desktop
• Language

And here is useful link with data-mining demo:
