  1. P3PA New Standard in Online Privacy http://www.w3.org/P3P/ Overview and Demos from Summer 2000

  2. P3P1.0 – A first step • Offers an easy way for web sites to communicate about their privacy policies in a standard machine-readable format • Can be deployed using existing web servers • This will enable the development of tools (built into browsers or separate applications) that: • Provide snapshots of sites’ policies • Compare policies with user preferences • Alert and advise the user

  3. P3P is part of the solution P3P1.0 helps users understand privacy policies but is not a complete solution • Seal programs and regulations • help ensure that sites comply with their policies • Anonymity tools • reduce the amount of information revealed while browsing • Encryption tools • secure data in transit and storage • Laws and codes of practice • provide a base line level for acceptable policies

  4. Using P3P on your Web site • Formulate privacy policy • Translate privacy policy into P3P format • Use a policy generator tool • Place P3P policy on web site • One policy for entire site or multiple policies for different parts of the site • Associate policy with web resources: • Place P3P policy reference file (which identifies location of relevant policy file) at well-known location on server; • Configure server to insert P3P header with link to P3P policy reference file; or • Insert link to P3P policy reference file in HTML content

  5. P3P policies • Machine-readable (XML) version of web site privacy policies • Use P3P Vocabulary to express data practices • Use P3P Base Data Set to express type of data collected • Capture common elements of privacy policies but may not express everything (sites may provide further explanation in human-readable policies)

  6. Who is collecting data? What data is collected? For what purpose will data be used? Is there an ability to opt-in or opt-out of some data uses? Who are the data recipients (anyone beyond the data collector)? To what information does the data collector provide access? What is the data retention policy? How will disputes about the policy be resolved? Where is the human-readable privacy policy? The P3P vocabulary
