Four Missed Opportunities for Privacy
The NY Times has a blog posting on the occasion of the Internet advertising industry's release (PDF) of what it describes as tough new standards governing the collection and use of data about users' behavior. The Times' Saul Hansell describes these "new" standards as more of the same old status quo, and outlines four privacy-enhancing ideas, being discussed by Google, Yahoo, the FTC, and Congress, that the IAB has completely ignored. These principles are: every ad should explain itself; users should be able to see data collected about them; browsers should help enforce user choices about tracking; and some information (medical and financial) is simply too sensitive to track.
Ads will never "explain themselves" and companies will never reveal how much information they harvest from you (outside of lengthy, dull, usage terms written in Jargon.) Either case would make users skittish, and there's too much money involved for either them or congress to want to do anything about it.
As for medical and financial information, it's incredibly sensitive, yes, but having it tracked is incredibly convenient for both lay people and companies (if inconvenient for the IT staff who have to secure them.) Either way, these records have to be kept somewhere and somehow and be accessible in some way to people who need them (doctors and banks.)
The only change I see possible is improvement in the browsers. If any privacy change does occur, you can bet that it will start with either Firefox, Opera, or some non-mainstream browser, and then be eventually adopted by IE. Don't expect the end-users to know how to enable any privacy features though.
Install adblock extension, disable 3rd party cookie files, use software that ads advertising domains to your hosts file.
As far as I can tell the internet doesn't even have banner ads anymore.
