But do people know or feel the need for P3P? Personally, I think people should take it more seriously. I do know that third party cookie rejection rate has been at the highest during the past 3-4 years and it is high time that websites start feeling the need for introducing valid and sound privacy policies. Third party cookies are a piece of text/data placed on your machine that do not belong to the website you have visited. If you go to www.msn.com and you find an Omniture 2o7.net cookie on your machine, the 2o7.net cookie is the third party cookie tracking your browsing details in this scenario.
According to a WebTrends article posted in 2005, the cookie rejection rate was as high as 12-15%. So we can guess that figure should be between 20-25% in 2006-2007. The new versions of browsers like Firefox and IE7 aren’t helping matters either. The default settings in the Privacy tab of IE7 are designed to automatically block third party cookies that do not have a P3P policy. Look at the below screenshot.
It was a good practice for me to look around for information about P3P and believe that it is a positive step taken to make the users aware about what kind of data is being collected and how it could be attributed to their online behavior. Please feel free to add your opinions/criticisms.
