Integrating User Modeling Server with User Modeling Mediator on a personal Device

In today’s “active environments” users are equipped with smartpersonal device and they are able to receive personal services from theirenvironment. However, provision of personalized services to users requiresaccurate modeling of users’ interests and needs and such information may notbe available to service provider. Previously suggested solutions, such as usermodeling servers and user modeling mediation demonstrated technologicallypossible solution to the problem of bootstrapping user models for such services.However, all the above solutions introduce privacy problem. This paperproposes a general framework for enhancing the privacy of user modeling inpersonalization systems, by keeping the user “in control” of his/her personalinformation. The combined user modeling server and mediation mechanismwill allow the user to explicitly select what information to disclose to serviceprovider and to transfer it at the right format.
