Even with Cookies, How to manage your Information Online
A certain amount of information is by default sent to a site when you take a visit to that site. This information may include the following:
IP Address: Each computer on the internet has a specific and unique IP address. Which may be either a static or dynamic IP address. You can check your computer's IP address at any given time by visiting www.showmyip.com
Domain Name: The internet is divided into domains, and every account associated with a user has one of those domains. These domains can be identified by checking the URL; for example, .edu indicates an educational institution, .gov indicates a US government agency, .org refers to organization, and .com is for commercial use.
Software Information: It is very much possible for an organization to identify which browser, including the version that you used to visit its site, and also the operating system your computer is running.
Page Visits: Information about which pages you visited, how long you stayed on a given page, and whether you came to the site from a search engine is often available to the organization operating the website.
If the site you're visiting is malicious, files on your computer, as well as passwords stored in the temporary memory, may be at risk.
Are you exposing any other personal information?
How can you limit the amount of information collected about you?
Be very careful of giving out sensitive and personal information – unless the site is a trusted one, don't give your address, password, or ATM Card information. Look for indications that the site uses SSL to encrypt your information.
Browse safely - Be careful which websites you visit; if it seems suspicious, leave the site. Also make sure to take precautions by increasing your security settings, keeping your virus definitions up to date, and scanning your computer for spyware.
