On January 26, Google said that after being opposed by regulators and advertisers, Google decided to abandon the previous "privacy sandbox" technology and instead provide a new advertising online system "Topics" to block cookies in Google's browser.
Google previously announced that it would block cookie technology starting in 2022, and this provision was later postponed until the end of 2023. In existing Chrome browsers, websites need to obtain the consent of the user to request cookies. For this operation of Google, Xiao Lei is supported. Users who do not want to leak privacy can click "Reject".
However, some websites are more ugly, the user clicked to refuse, it will still pop up, has been occupying part of the page, simply forced to die obsessive-compulsive disorder.
Cookie technology has also been used for many years, and there are indeed many flaws in itself. Cookies on HTTP pages are transmitted in clear text and data can be intercepted by hackers. In addition, the size of each cookie is limited to about 4KB, and large content cannot be stored.

Today, third-party advertisers rely heavily on cookies to personalize ads, which is very effective in improving the accuracy of their advertising delivery. Since it is accurate to the individual, it is bound to have an impact on personal privacy. Google's new advertising system, Topics, goes from targeting one person to a group of people with similar browsing history.
Previously, Google also launched a program called "Joint Queue Learning (Floc)," which still targets a group of users. However, Topics reduces these "queues" from tens of thousands to thousands, and it will also use human administrators to make the division of "Topics" more precise.
Although chrome accounts for about 70% of the global market share, users are increasingly concerned about their privacy and security, and if Google does not make progress in this regard, users may turn to browsers such as Firefox. For Google's new technology, Xiao Lei, as an ordinary user, is supportive. As long as the new technology does not derive new information tracking methods, the user's personal privacy can be more guaranteed.
