Privacy-Preserving Architecture for Cloud-IoT Platforms

We propose a cloud-IoT architecture, called Data Bank, aiming at protecting users' sensitive data by allowing them to control which kind of data is transmitted by their devices and providing supportive tools for agreement visualisation and privacy-utility trade-off. The architecture consists of several layers, from IoT objects in the lower layer to web and mobile applications in the top layer, with regulated communication mechanisms to transfer data from the lower level to data processing services in the top level. We illustrate our proposal with an example in a smart vehicle environment.
