The Do Not Track header ( DNT ) is the proposed HTTP header DNT field that prompts the web application to disable tracking or its cross-site tracking of users (no fixed ambiguity resolved) from individual users. The Do Not Track header was originally proposed in 2009 by researchers Christopher Soghoian, Sid Stamm, and Dan Kaminsky. Attempts to standardize Do Not Track by the W3C in the Tracking Preferences Tracking Working Group (DNT) are currently in the status of Candidate Recommendation (as of 20 August 2015).
In December 2010, Microsoft announced support for the DNT mechanism in its Internet Explorer 9 web browser. Mozilla's Firefox became the first browser to implement the feature, while Internet Explorer, Apple Safari, Opera and Google Chrome all later added support.
The header column name is DNT and currently accepts three values: 1 if the user does not want to be tracked (opt-out) , 0 if the user agrees to be tracked (choose) , or null (no headers sent) if the user has not stated their preference. The standard behavior required by the standard is to not send headers unless the user activates the settings via their browser or their choice is implied by using that particular browser.

Histori
In 2007, several consumer advocacy groups asked the U.S. Federal Trade Commission. to create a Do Not Track for online advertising list. The proposal will require that online advertisers submit their information to the FTC, which will compile a list of domain names which can be read by machines used by the company to place cookies or track consumers.
In July 2009, researchers Christopher Soghoian and Sid Stamm created a prototype add-on for the Firefox web browser, implementing support for Do Track headers. Stamm was, at the time, a privacy engineer at Mozilla, while Soghoian soon after that started working at the FTC. One year later, during a US Senate hearing, FTC chairman Jon Leibowitz told the Senate Trade Commission that the commission was exploring the idea of ​​proposing a "no-track" list.
In December 2010, the FTC issued a privacy report calling for a "no track" system that would allow people to avoid being monitored online.
One week later, Microsoft announced that the next browser will include support for Tracking Protection Lists, which blocks consumer tracking using blacklist provided by third parties. In January 2011, Mozilla announced that its Firefox browser will soon provide a Do Not Track solution, through the browser header. Microsoft Internet Explorer, Apple Safari, Opera, and Google Chrome then added support for the header approach.
In August 2015, a privacy coalition led by the Electronic Frontier Foundation using the W3C's Tracking Preference Expression (DNT) standard proposed that "Do not track" was a goal for supporters to demand business.
Internet Explorer 10 default settings controversy
When using the "Express" setting during installation, the Do Not Track option is enabled by default for Internet Explorer 10 and Windows 8. Microsoft faces criticism of its decision to enable Do Not Track by default from advertising companies, which says that the use of Head Do Not Track should be an option created by the user and should not be automatically enabled. The companies also said that this decision would violate the Digital Advertising Alliance agreement with the US government in honor of the Do Not Track system, as the coalition says it will only honor such a system if it is not enabled by default by a web browser. But a Microsoft spokesman defended his decision, stating that users would prefer a web browser that automatically respects their privacy.
On September 7, 2012, Roy Fielding, a standard Do Not Track writer, sends a change to the Apache HTTP Server source code, which will make the server explicitly ignore any use of the Not Traced Internet Explorer 10 headers. Fielding confirms that Microsoft's decision "deliberately breaking" Do Not Track specification because "it does not protect anyone's privacy unless the recipient believes that it is set by real humans, with a real preference for privacy over personalization." The Do Not Track specification does not explicitly mandate that the use of Do Not Track is actually an option until after the feature is implemented in Internet Explorer 10. Fielding shows that Microsoft knows false signals claiming that the user has chosen Do Not Track will be ignored, and that the goal is to effectively giving the illusion of privacy while still serving their own interests. On October 9, 2012, the patch Fielding was commented on, restoring the previous behavior.
On April 3, 2015, Microsoft announced that in Windows 10, it would conform to the specifications and no longer enable Do Not Track as part of the default "Express" setting of the operating system, but the company would "provide customers with clear information about how to enable the feature this in the browser settings if they want to do it ".

Operation
When a web browser requests content or sends data using HTTP, it may optionally include additional information in one or more items called "headers". Do not track add headers (DNT: 1), indicating that users do not want to be tracked. The browser user has no control whether the request is honored or not.
Effectiveness
There are no legal or technological requirements for DNT use. Websites and advertisers may appreciate or ignore DNT requests. The Digital Advertising Alliance, the Council of Better Business Bureaus and the Direct Marketing Association does not require members to respect the DNT signal. There are organizations such as DataNeutrality that are involved in setting the DNT guidelines for private companies involved in data collection.
Microsoft itself does not comply with the DNT header, which states "Since there is no general understanding of how to interpret DNT signals, the current Microsoft service does not respond to the browser's DNT signal."
