Professor Lorrie Faith Cranor, Carnegie Mellon University, discusses the history and value of leveraging Platform for Privacy Preferences (P3P) for privacy policies.
If you don't make a choice about Do Not Track, your browser will decide for you. If your browser is Firefox and you live in the US, the choice will effectively be to keep tracking turned on. If your browser is Microsoft IE 10, tracking will be turned off. Critics say the choice should be up to users. But in the US a non-choice will be interpreted as choosing to be tracked. While DNT interfaces should facilitate choice, active user participation should not be a requirement for privacy.
Safari is not the only browser that has privacy protections that are being circumvented. Thousands of websites are also exploiting a loophole that circumvents IE cookie blocking based on a 10-year-old web standard called P3P.
Lorrie Faith Cranor explores the privacy features of Microsoft's new browser version in light of privacy issues, in particular "Do Not Track" concerns.
