Preserving the users´information privacy in location-based and context-aware solutions

Preserving the privacy of the users’ information should be an essential requirement in information management systems. The mobility provided by context-aware services has increased the complexity of ensuring this challenge by allowing users to obtain, share, and provide information at anytime and anywhere. Addressing this challenge requires automatic mechanisms that allow users to control their information at realtime and on demand. In order to achieve these requirements, we proposed several context-aware solutions that allow users to manage the privacy of their information through policies. The privacy-policies managed by our solutions let users decide at real-time what, where, when, how, to whom, and at which level of precision they want to reveal their information.
