Google Inc. announced<\/a><\/noindex> regarding its intention to completely cease support for third-party cookies in Chrome within the next two years, which are set when accessing websites other than the current page's domain. Such cookies are used to track users' movements across websites in ad networks, social media widgets, and web analytics systems.<\/p>\n

As well as the announcement<\/a><\/noindex> made yesterday to unify the User-Agent header, the push against third-party cookies is part of an initiative Privacy Sandbox<\/a><\/noindex>aimed at achieving a balance between users' needs for privacy and the desire of ad networks and websites to track user preferences. By the end of this year, in an origin trial<\/a><\/noindex> additional APIs are expected to be included in the browser for measuring conversions and personalizing ads without the use of third-party cookies.<\/a><\/noindex> To determine a user's interest category without individual identification and without tying to the history of visits to specific sites, ad networks are suggested to use the <\/p>\n

Floc API to assess user activity after clicking on ads \u2014 the<\/a><\/noindex>, to assess user activity after clicking on ads \u2014 API API, and to segment users without using cross-site identifiers \u2014 the<\/a><\/noindex>, and to differentiate users without using cross-site identifiers \u2014 API API. The development of specifications for displaying targeted ads<\/a><\/noindex>without compromising privacy is being handled
\nby a separate working group. Currently, in the context of protecting against the transmission of cookies during<\/a><\/noindex>, established under the W3C organization.<\/p>\n

CSRF attacks, the SameSite attribute specified in the Set-Cookie header is set to 'SameSite=Lax' by default in Chrome 76, which limits the sending of cookies for inserts from third-party sites, but sites can override this restriction by explicitly setting SameSite=None when installing cookies. The SameSite attribute can take two values: 'strict' or 'lax'. In 'strict' mode, cookies are prevented from being sent for any type of cross-site requests. In 'lax' mode, softer restrictions apply, blocking cookie transmission only for cross-site sub-requests, such as image requests or content loading via iframe.<\/a><\/noindex> the SameSite attribute specified in the Set-Cookie header is, starting from Chrome 76, by default set to 'SameSite=Lax', which limits the sending of Cookies for requests from third-party sites, but sites can override this restriction by explicitly setting SameSite=None when installing Cookies. The SameSite attribute can take two values: 'strict' or 'lax'. In 'strict' mode, Cookies are prevented from being sent for any type of cross-site request. In 'lax' mode, softer restrictions apply, and the transmission of Cookies is blocked only for cross-site subrequests, such as image requests or content loading through iframes. <\/p>\n

In Chrome 80, scheduled for February 4, stricter limitations will be implemented to prohibit the processing of third-party Cookies for requests without HTTPS (with the SameSite=None attribute, Cookies can only be set in Secure mode). Additionally, work continues on implementing measures to identify and protect against the use of tracking circumvention techniques and hidden identification ('browser fingerprinting').<\/p>\n

Let us remind you that in Firefox, starting from the release 69<\/a><\/noindex>, tracking cookies from all third-party systems are ignored by default. Google considers such blocking justified, but it requires prior preparation of the web ecosystem and offering alternative APIs for tasks that previously relied on third-party cookies, without compromising privacy and undermining the monetization models of advertising-funded websites. In response to the cookie blocking without providing alternatives, ad networks have not stopped tracking but have instead resorted to using more sophisticated methods based on hidden user identification (fingerprinting) or through creating<\/a><\/noindex> for tracking subdomains in the website's domain where the ads are displayed. <\/p>\n
