Whether you are searching for the most suitable product or are just curious to explore the latest trends, the Internet is the place to go. With its vast and ever-growing repository of information, the Internet has evolved into an invaluable resource for exploring and discovering practically anything. It allows you to easily compare products and prices, find ratings from other users, and access a wide range of educational content.

Frequently, when visiting these websites, a pop-up stating that the site uses cookies appears along with the buttons Accept, Decline, and Manage. Have you ever wondered what cookies are, why they appear on websites, and the implications of accepting them?

On Day 3 of Data Privacy Week, let’s learn about cookies.1,2,3


Cookies are small text files that are stored on your computer or mobile device when you visit a website. 

Websites use cookies to store information about you and your browsing habits, such as what pages you visit, what products you buy, and where you are located. This can help to make your web browsing experience more convenient and efficient, as websites can remember what a user has done before and provide a tailored experience for them.

However, this data may be sold to third-party companies, who may use it to target you with advertisements or sell your personal information to a few others who may use it for malicious purposes.  

Therefore, it is essential that you understand what they are and how to manage them for a better and safer browsing experience.

Different Types of Cookies

The three main categories of cookies are session cookies, persistent cookies, and third-party cookies.

Session Cookies: When you visit a website, the server stores a small amount of data on your computer in the form of a session cookie. This cookie is only stored temporarily and is deleted when you close the browser or log out of the website. For instance, when you log into a banking website, the server will store a session cookie on your computer that contains your username and other authentication information necessary to keep your session active. Once you log out of the session, the cookie gets deleted automatically.

Persistent Cookies: Persistent cookies are created when you visit a website and are stored in your computer for a longer time (or until you delete them). They are often used to remember login information, preferences and other data so that websites can provide a more personalized experience. They also help websites track user activity and behaviors, allowing them to improve their services.  For instance, persistent cookies can allow a website to remember choices you made in the past, such as the language you prefer to view a website in, or the items you may have placed in an online shopping cart.

Third-party Cookies: Websites other than the one you are visiting can create and save third-party cookies on your computer. These cookies track your activity across multiple websites, such as which pages you have visited, where you have clicked, and so on. This information is then used to deliver targeted ads to you. For example, if you visit a clothing website, you may notice advertisements for clothing on other websites you visit.

Accepting and Declining Cookies

Often, when you come across “privacy and cookie policy” on a random website, there are chances you may unconsciously accept or decline to give the website permission to track your cookies without even considering the implications. Do you know that this could have an impact on your browsing experience and, more importantly, the confidentiality of the data you give the website access to?4

By accepting cookies, you are essentially giving a website access to all the data associated with that cookie. This data can include your browsing habits, location, IP address, and other personal information that you may not have intended to share. This could be used to target you with ads, track your movements, or even worse, steal your identity or other sensitive information. For example, malicious actors can use the data collected by tracking cookies to target you with phishing emails from what seem to be legitimate sources, such as your bank or other financial institution.   

However, it is also important to remember that not all cookies are created equal. Some cookies are essential for website functionality, while others are used for advertising and analytics. Therefore, it is important to carefully review a website’s privacy and cookie policy before accepting or rejecting cookies. 

Tips to Manage Cookies for Safe Browsing Experience

Here are some tips that can help you have a safe browsing experience.5,6,7

  • Regularly check the settings of your browser to ensure that it is up to date and secure. If possible, disable all cookies by default to be on the safe side. You can accept cookies of trusted websites if you want to.
  • Be aware of what information your browser shares with websites, and make sure it is only the information that you want to share. Read the privacy and cookie policy of the website you are browsing before accepting cookies. 
  • Delete cookies from your browser on a regular basis to ensure that your personal information is not being collected and stored without your knowledge. 
  • Do not accept cookies on unencrypted websites. If the website is not encrypted, data sent from the website is sent in plain text, making it vulnerable to theft. Accepting cookies on unencrypted sites could put your data at risk.
  • Do not accept cookies flagged by antivirus software. Cookies flagged by antivirus software are likely malicious, and by accepting these cookies, you may be exposing your device to malicious software that can steal personal data or cause other damage.

Now that you know what cookies are, you know what to do the next time a cookie pop-up appears. To read more blogs like this, go to BYJU’S FutureSchool Blog.
