kung same device/browser yung ginamit mo sa pag register mo sa totoong n# mo at dyan sa fake registration mo kabahan kana dahil hndi mo alam na nagccapture yung telco site ng browser serial n# mo, cøøkíés at ip address mo, etc.
If the owner of a web site wants to track who their users are as much as possible, what things can they capture (and how). You might want to know about this in order to capture information on a site you create or, as a user, to
prevent a site from capturing data on you.
Here is a starting list, but I'm sure I have missed some important ones:
- Referrer (what web page had the link you followed to get here). This is a HTTP header.
- IP Address of the machine you are browsing from. This is available with the HTTP headers.
- User Agent (what browser you are using). This is a HTTP header.
- cøøkíé placed on a previous visit. This is a header, available only if a cøøkíé was placed earlier and was not deleted by the user.
- Flash cøøkíé placed on a previous visit. Some users turn off cøøkíés, but very few know how to turn off Flash cøøkíés. Works like a normal cøøkíé although it depends on Flash.
- Web Bugs. Place something small (like a transparent single-pixel GIF) on the page that's served up from a 3rd party. Some third parties (such as DoubleClick) will have their own cøøkíés and can correlate with other visits the user makes (for a fee!).
