How Unique is your web Browser ?

Published by hirantha at 8:05 PM under Security | Internet Explorer | Firefox | Chrome | Opera

Electronic Frontier Foundation (EFF) has published a paper on browsers being tracked by it's unique fingerprint. It turns out our browsers are more unique than we would like to think they are so it is possible for websites to track users around using the unique fingerprint. While it may not be possible to know the exact user's identity, tracking from one web location to another is definitely a possibility. User agent string, system fonts, screen resolutions and much more of the computer attributes all contributes to the unique fingerprint of computer + browser combination. Disabling Javascript and active contents help with this a little bit but you need to decide whether privacy is worth losing the ability to view the active content.

To test how unique your computer + browser combination, goto https://panopticlick.eff.org/ and click on the "Test Me" button.

After installing the add-on, the links from search engines are tagged with extra symbols showing whether the site's "reputation" level. Very simple to understand, red means potentially bad site and green means good site.

WOT is available for both Firefox and IE . If you choose to use it, remember to contribute back to the project back by helping to rate sites as you visit them.
