When you visit a website, cookies are little bits of information that are stored on your browser. They monitor your internet activity, keep track of your choices, and display customised advertisements to you. But cookies also have certain disadvantages. By gathering private data about you, like browsing history, location, and device information, they potentially violate your privacy. They can also use up memory and bandwidth, which will negatively impact the speed of your browser. Additionally, they may put your security at risk by giving hackers access to your information or by infecting your browser with dangerous code.
Google intends to phase away third-party cookies in Chrome by 2024 for a number of reasons. Cookies placed by websites other than the host are known as third-party cookies.
How did Google come up with their plan to eliminate cookies?
In 2019, Google first revealed its Privacy Sandbox concepts. The main objectives were to phase out third-party cookies in Chrome and investigate potential alternatives to targeted advertising. Numerous technologies were put forth to take this position. But by 2021, Google FLoC (Federated Learning of Cohorts) had become the front-runner, and the business had started conducting tests. However, FLoC was eventually dropped as well because of privacy issues.
Topics emerged as the most recent effort to strike a compromise between ad targeting and privacy. Ad Topics, in particular, is a component of the larger Privacy Sandbox scheme, which aims to switch Chrome from cookies to tracking that is more focused on privacy.
For instance, if you visited websites pertaining to "Travel" and "Photography," those subjects might be given. The subjects are updated every week and are kept for a period of three weeks.
A website may request these topics from the Topics API when you visit in order to display advertising that are relevant to your interests. Advertisers receive a high-level summary of a user's current interests instead of individual IDs. Your device computes topics locally instead of sending Google your entire history. The firm maintains that this method discloses less information about your individual surfing patterns.
