Understanding Internet Cookies: What You Need to Know
Internet cookies have become an unavoidable part of web browsing, with pop-up banners prompting users to accept them. But what exactly happens when we click ‘accept all’? In the first installment of the ‘What even is…?’ series, The University of Queensland’s Contact magazine explores the role of cookies in digital interactions with insights from Dr. Priyanka Singh, UQ Lecturer in Cyber Security.
What Are Internet Cookies? Cookies are small pieces of data stored on a user’s device when visiting a website. According to Dr. Singh, they facilitate smoother and more personalized browsing experiences by exchanging information between the browser and the website’s server. These data packets help retain user preferences, login credentials, and shopping cart items.
Why Do Websites Use Cookies? Websites rely on cookies to enhance user experiences. They keep users logged in, remember language preferences, and track shopping activity. Cookies work by storing unique session IDs that allow websites to recall user interactions.
Why Are Cookie Pop-ups Everywhere? The rise in cookie consent requests is largely due to privacy laws like the European Union's General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA). These regulations mandate websites to obtain explicit user consent before storing or accessing cookie data.
Dr. Singh highlights key privacy concerns associated with cookies:
Tracking: Cookies track browsing habits, leading to targeted advertising that some users find intrusive.
Data Breaches: If a website is compromised, stored cookie data can be accessed by cybercriminals.
Lack of Transparency: Many websites use complex tracking mechanisms that are difficult for users to understand.
Are Cookies Being Phased Out? The digital world is moving toward a ‘cookieless future,’ particularly in phasing out third-party cookies that track users across different websites. Major browsers like Chrome, Firefox, and Safari are restricting third-party cookies in favor of privacy-focused alternatives.
Should You Clear Cookies? Dr. Singh advises users to manage cookies proactively:
Regularly clear cookies to protect privacy and prevent tracking.
Block third-party cookies to reduce online tracking.
Customize browser settings to allow only trusted sites to set cookies.
As privacy regulations evolve, internet users are encouraged to take control of their data and make informed decisions about their digital footprint.
