Unlike cookies, trust tokens or trust tokens are designed to authenticate a user without having to know their identity. Trust tokens will not be able to track users on sites, because in theory they are all the same, but they will allow sites to prove to advertisers that they were real users and not bots who visited a site or clicked on an ad.
OR Google was a little slower to suggest a solution for third-party tracking cookies that no one seems to want. Safari and Firefox browsers already block them by default, although Safari is much more aggressive.
However, Mike Schulman, its vice president Google for the privacy and security of the ads, repeated in a suspension on the blog that the company is still planning to phase out cookies third parties in Chrome.
Furthermore, the Google will make some changes to the "why this ad" button that lets you see why some ads are targeting you and not someone else. The new add-on "about this ad" will also provide the verified name of the advertiser, so you can say which companies are targeting you but also to understand how the Google collects your personal ad data. We will see the new addition to the ads at the end of the year.
The company also announced an extension for the Chrome browser. It is currently in alpha phase, and is called Ads Transparency Spotlight. This extension should provide "detailed information about all the ads you see on the web".
Users will be able to see the details of the ads on a particular page, see why the ads are displayed on a page and a list of other companies and services on the page, site details or content delivery networks.
