Towards Privacy-preserving Data Sharing in Smart Environments

The increasing development of IoT is dramatically changing the way people share information and communicate with their surrounding environment, enabling a constant, invisible and sometimes unintended data exchange, between things and people. This extension of the current Internet to everyday life scenarios leads identity management has to face new challenges due to the inherent nature and requirements of this paradigm. This work gives an overview of recent privacy-enhanced technologies such as attribute-based cryptography and anonymous credential systems, as well as their application on IoT scenarios. Additionally, based on such mechanisms, we offer a framework which is designed to enable a secure and privacy-aware data sharing on the Future Internet.
