So are you purposing each person's data is not stored anywhere and must be manually typed? Or something where each person controls where their data is stored and has to explicitly give access to sites in order to read the data? I feel like the second option would be feasible if you could somehow get the major sites to agree they would pull the data each request rather than storing it in their databases.
