On the national policy front, or "Big 'P' Policy, both privacy and security issues are rising to the fore. Do not track mechanisms are, to quote a New York Times recent article on this subject, "features on browsers — like Mozilla’s Firefox — that give consumers the option of sending out digital signals asking companies to stop collecting information about their online activities for purposes of targeted advertising." The market sector is not happy. Microsoft is releasing version 10 of its web browser, Internet Explorer, with a default do not track setting; to allow cookies or other tracking requires the user to change the setting. Business interests have reacted angrily, with the Association of National Advertisers sending Microsoft's CEO, Steve Ballmer, an open letter objecting to that decision.
