ISSSR 2019 Keynote Speech

Taming the “PII in the Sky.” On Personally Identifiable Information, Blockchain and Internet of Things. Historical Trends and Future Challenges


Over the last few decades there has been a growing interest in protecting the security and privacy of personally identifiable information (PII), and new legislation has been passed by various governments with the intent of legally enforcing the protection of such sensitive data. With the deployment of the Internet of Things (IoT) massive volumes of “big data” are being collected continuously and stored on the cloud, and the issue of protecting the “PII in the sky” is becoming increasingly challenging. While IoT has given rise to endless opportunities for collection and sharing of data, Blockchain technologies have been successfully used to secure the authenticity of data and transactions involving the exchange of sensitive data. In this presentation we review some historical trends and challenges related to the evolution of data collection and storage and we discuss areas that will likely require the most attention over the next decades.
