They might sound delicious, but tracking cookies aren’t a tempting dessert item. Cookies store small amounts of data that you’ve entered into a particular website to make it easier for you to access information. Cookies are the reason you don’t have re-enter your username and password every time you click a new link on Facebook. Without cookies, you would need to continually validate your credentials while using a website.
How Do Tracking Cookies Work?
Regular cookies are small text files that store your preferences for a web page so the page automatically loads with your selected options each time you visit. Tracking cookies do the same thing, but they take it one step further. In addition to storing your options and preferences, tracking cookies also keep track of your online activities.
This data is typically linked to your Internet Protocol (IP) address. The tracking cookie sends logs of your online behavior to a remote database so they can be analyzed. Marketers synthesize your info along with that of millions of other users to help spot trends and understand online behavior. This is why you might start seeing an abundance of ads for a particular company after you clicked on a link to that brand. Some tracking cookies help advertisers customize the ads you see with your name or location.
Do Cookies Know My Secure Information?
When you receive an ad that calls you by name, it can be unnerving. This is why many people see tracking cookies as an invasion of privacy. But cookies don’t scan your computer for personal information, and the data they collect is encrypted and usually worthless to any party other than the server or website that created it. In addition, cookies can only capture information that you’ve provided to the website in question.
How Can I Get Rid of Cookies?
Clear Out Cookies
Make it a habit to regularly clear out cookies in your web browser. It should be a straightforward process that you access in the privacy settings of the browser.
Decide Which Cookies You Want
You have the option to set the level of access cookies have. You can allow all cookies, but that’s not what IT security pros recommend. Your best bet is to disallow third-party cookies, which naturally weeds out most suspect cookies. Be aware that if you disallow all cookies, some websites you visit may not function properly.
