Distributed data trust using blockchain technology
Sara Rouhani,
Ph.D. Candidate and sessional lecturer, computer science department, the University of Saskatchewan

The lack of transparent and reliable infrastructure for data sharing prevents many data owners from sharing their data. Data trust is a paradigm that facilitates data sharing by forcing data controllers to be transparent about the process of sharing and reusing data. Blockchain technology stands the potential to present the essential properties for creating a distributed, practical and secure data trust framework. Blockchain can transform current auditing practices and utilize automatic enforcement of smart contracts to establish trust without relying on intermediaries. In this seminar, blockchain as an infrastructure for developing a data trust framework will be discussed. This talk introduces two decentralized applications based on blockchain for sharing healthcare data and physical access control as examples of decentralized access control applications, followed by introducing the decentralized attribute-based access control system. These studies provide auditability and transparency required for data sharing and access control systems and, ultimately, data trust framework. In the end, this seminar presents a distributed and adaptive data trust framework using blockchain technology. The proposed framework addresses the concerns of both data owners and data users. Data owners have full control over their data access management. Data users are also enabled to assess the quality and trustworthiness of the data that have been shared with them.

BIO

Sara Rouhani is currently a Ph.D. candidate and a sessional lecturer in the computer science department at the University of Saskatchewan, supervised by Prof. Ralph Deters. She is also, research assistant at the University of Alberta, Intelligent Systems laboratory and Intelligent Energy Systems laboratory at the computer engineering department. Her research interests are using blockchain and smart contracts for developing distributed access control and data trust. She has examined the potential of blockchain in interdisciplinary areas such as healthcare, business process management, agriculture and energy systems. As a part of her research, she has collaborated with various industrial partners. For instance, she has collaborated with the Linux Foundation as a project mentor and blockchain developer. She also has worked with an Alberta-based health care project as a Mitacs researcher. Besides, she has worked with a start-up in the medical insurance field as a team leader. She is currently also working with the SKSIS start-up in digital soil mapping and recommended sampling at the agriculture department of University Saskatchewan as a blockchain developer.
