Every website you visit asks for your allowance on your cookies. Cookies in our life taste great but the cookies on the Internet are quite different. Some optimize your browsing experience since the cookies allow your account login information remembered and it can be automatically filled in as soon as you step on that website. However, your privacy is also challenged by cookies. It’s necessary to know more about website cookies and learn how to remove them on browsers for your online privacy’s sake.
What are Cookies?
Definition
Cookies, also called Internet cookies, web cookies or HTTP cookies, are a type of small text files containing all the interaction between you and a website. As soon as you visit a website, a cookie will be generated by the website, based on which your identity as a user will be recognized.
The data contained in a cookie file is so little that fails to be used to recognize your real identity. It usually includes:
- The name of the website domain that sent the cookie;
- The cookie’s expiration date;
- A unique ID that is randomly generated, which is beneficial to recognize a returning user.
Classification
Based on the difference on how cookies work, cookies can be classified into session cookies, permanent cookies and third-party cookies.
Temporary Cookies
Session cookies, also called temporary cookies, are stored in temporary memory and won’t be expired. Session cookies are established when users enter the website and only serve as they browse the web pages. Once the browser is closed, the cookies will be permanently deleted. Session cookies won’t collect any information from your device so that they won’t cause any harm to your online privacy.
Permanent Cookies
Permanent cookies can help websites remember and recognize the identity of website visitors. Do you notice you are suggested to click “Keep me logged in” on a website? That is the role permanent cookies play. Permanent cookies testify the identities of users so that users won’t need to refill their login information again and again if they visit the website repeatedly. Permanent cookies can help websites remember numerous settings like your preferred language, theme or what you left in the shopping basket on a shopping website.
Permanent cookies bring forward convenience to website users because they don’t need to reenter the login information. When it comes to privacy and security, however, it’s optimal to ban them. Once the website or your devices get hacked, your personal data will possibly be leaked through permanent cookies.
Third-Party Cookies
Third-party cookies are usually used to track users across sites. Then, advertisers will be able to serve you targeted ads based on the accumulated data from due to third-party cookies. Third-party cookies are usually set on websites with external content or sources like ads and banners leading to external websites.
Supercookies
The reason why supercookies are regarded to be super lies in the fact that they can be embedded into your device without any of your knowledge. Worse still, you can hardly get those cookies removed. Moreover, they contain so much information, including browsing histories, identity verification information and ads tracking data. Therefore, they are badass cookies that you should avoid.
Do Cookies Cause Any Harm?
First, never mix cookies with viruses.
Compared with viruses, cookies are harmless unless your privacy is compromised by them. As marketing technologies become increasingly complicated and the Internet becomes increasingly popular, it’s possible cookies may get “crazy” and be used to steal Internet users’ online data. They could be attacked by hackers and your online information will be exposed and abused.
To stop being tracked by any party, it’s suggested that cookies should be cleared so as to protect your online identity against theft.
