A Privacy Preserving Framework for the Internet of Things

With the proliferation of the Internet of Things (IoT) and cloud based services, it becomes very essential to design and implement efficient mechanisms, to protect the users private information and secure them, taking into account the IoT devices limited computational and storage capabilities. In addition, these devices are usually accessed by multiple users, and are connected to a cloud service provider, that have an access of the users data. In this paper, a privacy preserving framework is proposed that utilizes Fog layer, which act as intermediator between the IoT devices and the cloud, where users data are anonymized and secured. Further, a case study in the field of healthcare is described that shows the importance of the proposed framework.
