20090327397 | MANAGING USER PERSONAL INFORMATION ACROSS WEB SITES - A method of managing user personal information across a set of service provider sites is implemented, preferably as a web browser plug-in function. As a user navigates to a service provider web site and performs an interaction involving user identity attribute data, the interaction is recorded for later replay. Typically, the interaction is a graphical user interface (GUI) interaction. At a later time, previously-recorded interactions at service provider sites are replayed automatically, i.e., without requiring the user to navigate back to the individual sites and perform the interactions, and (during the replay operation) the user's previously-entered identity attribute data is located and retrieved. A display of the identity attribute data collected from the service provider sites then can be examined, e.g., for any inconsistency among the data. If the user then updates identity attribute data for a given service provider site, the identity attribute data for the site is automatically updated, once again without requiring the user to navigate to the site and re-enter the update directly. The method enables the user to ensure that his or her personal data stored at the service provider sites is up-to-date and synchronized. | 12-31-2009 |
