Privacy in a mobile environment

Future mobile network operators will provide users with all the information and services they want. Using a mobile phone for services is strongly dependent on personalization to provide the user with a comfortable experience. Hence many of these services (e.g. location, electronic wallet) will handle sensitive user data. This article presents a technique with which the network operator supports user needs for personal information privacy against third parties like Internet service providers. We propose a new and user-friendly method for handling privacy. The method is based on a privacy receipt mechanism for all personal data that the user agrees to be transferred to third parties. The role of the network operator in our scenario is that of consumer privacy protector, since the operators already store and process many sensitive user data and must comply with data protection legislation.
