Policy Engine

The Internet of Things (IoT) is changing the way we interact with our environment in domains as diverse as health, transportation, office buildings and our homes. In smart building environments, information captured about the building and its inhabitants will aid in development of services that improve productivity, comfort, social interactions, safety, energy savings and more.


The growing use of Internet of Things (IoT) technologies has the potential to improve waste management. Zotbins is a system that facilitates sustainable practices for individuals and improves waste management efficiency for organizations.


Policies have emerged as an important mechanism for specification of privacy requirements and Privacy Enhancing Technologies (PETs), such as differential privacy, data scrubbing and encryption technologies, are different ways to realize the privacy needs expressed in policies.
