Privacy-preserving global customization

Abstract

We present an architecture for global customization of web content, by w h i c h a w eb site can customize content for each visitor based on the activities undertaken by the same user on other, unrelated sites. Our architecture distinguishes itself in the privacy mechanisms it provides: each u s e r c o n trols what information a merchant can learn about her activities at other merchants, and each merchant controls to what other merchants the information it contributes is revealed. To a c hieve t h i s w e i n troduce novel data protection mechanisms for merchants and users. We further describe aspects of a prototype implementation of our architecture.

Masks: Managing Anonymity While Sharing Knowledge to Servers

“…[Arlein et al , 2000]proposed an architecture of shared user profiles, so that service providers could customize contents based even on user activities on other sites. This architecture preserves privacy because users can specify which information could be shared and grouped to form a profile.…”

A New Infrastructure for User Tracking Prevention and Privacy Protection in Internet Shopping

“…During this time, s 1 can track b's activities and store them in a new profile, say prof i , which belongs to a single identity, but he is unable to map these activities to b's identity. Then, b creates the order information including identifiers of these products, his name and address, to be contained in d 1 …”

“…But this threat can be tackled with the route protection scheme presented in expression (1). With this solution, a vendor only learns about his predecessor and successor in the shopping tour.…”

“…Such constraints influence the order of hosts to be visited, and thus, have to be considered when the agent route is composed. After having selected an appropriate order of shops, the CLAS re-arranges the sequence of the selected products as described in subsection 6.3, and then the MAG automatically creates a route according to equation (1). The CLAS is also responsible for the creation of profile messages which are destined for the CO.…”

“…Other work dealing with privacy protection concerning gathering information on customer activities in business processes was presented in [1,5]. There, they deal with privacy protection in customization and targeting.…”
