P3P

The Platform for Privacy Preferences Project (P3P) is a protocol allowing websites to declare their intended use of information they collect about web browser users. Designed to give users more control of their personal information when browsing, P3P was developed by the World Wide Web Consortium (W3C) and officially recommended on April 16, 2002. Development ceased shortly thereafter and there have been very few implementations of P3P. Microsoft Internet Explorer is the only major browser to support P3P. The president of TRUSTe has stated that P3P has not been implemented widely due to the difficulty and lack of value.
