Back in October I wrote a blog post titled "Privacy on the Internet is NOT "binary" Since then i've been giving Privacy a lot more thought. And so it seems has the IETF (The Internet Engineering Task Force)
From the IETF draft document published, November 14, 2011… (link)
The goal ( of this protocol ) is to allow a user to express their personal preference regarding cross-site tracking ( using an HTTP X request header ) to each server and web application that they communicate with via HTTP, thereby allowing each server to either adjust their behavior to meet the user's expectations or reach a separate agreement with the userto satisfy both parties. Key to that notion of expression is that it MUST reflect the user's preference, not the preference of some institutional or network-imposed mechanism outside the user's control.
In short they want the browser to send a message to the server that says don't track me. So I thought I would check back in to see how much progress they are making? It's a little techie but worth a read.
Privacy is a really tough problem to solve. My personal opinion is that the W3C is on the right track, however without the ability to influence to the Browser manufacturers there is little chance for implementation. It's going to require changes to the browser and to the Web server. Changing the HTTP protocol doesn't solve anything - as it's just a communication mechanism. What you have to change is both end of the pipe - and that is going to take some real innovation.(hint www.3pmobile.com)
