Privacy Preserving System for Real-Time Enriched-Integrated Service with Feedback to Providers

We have developed a secure data-providing system for an enriched-integrated service with feedback to providers featuring a verifiable attribute-based keyword search (VABKS). One potential application of the system is the Integrated Broadcast-Broadband (IBB) service, which acquires information related to broadcast programs via broadband networks. One of the services IBB provides is a recommendation service that delivers recommended information matching user preferences (such as TV programs) based on user viewing history. Another application is in mobile environments featuring smart-phone usage, where services based on user location can be suggested. In this study, we propose a secure system that adds the functions of privacy preservation and feedback to providers. Thereby the functions provide increased business benefit to users of the IBB service for mobile usage, and feedback property provides another benefit to the providers of IBB services.
