Microsoft claims Google bypasses Internet Explorer’s privacy controls

Now, Microsoft has posted a blog detailing how Google is also bypassing the privacy controls on their Internet Explorer browser.

The company claims:

We’ve found that Google bypasses the P3P Privacy Protection feature in IE. The result is similar to the recent reports of Google’s circumvention of privacy protections in Apple’s Safari Web browser, even though the actual bypass mechanism Google uses is different.

Google has responded to these charges by Microsoft by stating that the company is using outdated technology which is not practical on today’s world. Google said:

Microsoft uses a “self-declaration” protocol (known as “P3P”) dating from 2002 under which Microsoft asks websites to represent their privacy practices in machine-readable form. It is well known – including by Microsoft – that it is impractical to comply with Microsoft’s request while providing modern web functionality. We have been open about our approach, as have many other websites.

Today the Microsoft policy is widely non-operational. A 2010 research report indicated that over 11,000 websites were not issuing valid P3P policies as requested by Microsoft.
