About
Before joining the Cyber Security Centre and the Centre for Decentralised Digital Economy at the University of Surrey, I obtained a Ph.D. in Computer Science from the University of Porto, Portugal. My thesis was titled "Establishing Secure and Privacy-Preserving Digital Identity with Decentralised Digital Identity." I also hold a Master's degree in Business Information Systems and a Bachelor's degree in Computer Science (Digital Systems Security) from the University of Wollongong. Additionally, I have served as a teaching staff at the Department of Information Technology, Bayero University, Kano, Nigeria.

ResearchResearch interests
My current research work with DECaDE focuses on creating secure digital content provenance through a reputation and trust system. My research interests primarily revolve around secure digital identity management systems. From 2017 to 2023, I was a researcher at the Institute for Systems and Computer Engineering (INESC TEC) in Porto, Portugal. During this time, I participated in the European project "NanoSTIMA - Macro-to-Nano Human Sensing: Towards Integrated Multimodal Health Monitoring and Analytics CCRN - NORTE-01-0145-FEDER-000016," which aimed to develop a user-centered electronic data management platform for GDPR compliance. In this period, I proposed privacy-enhanced frameworks for the secure sharing, delegation, and access of personal data. Additionally, I have consulted for tech companies as a fraud prevention specialist and served as a reviewer for several renowned information security journals and conferences.

Sharing content, including photos, has become effortless thanks to social media and enterprise services. However, these platforms often overlook protecting content owners’ rights, such as proof of ownership, usage rights, and privacy. In this paper, we present a novel SSI application that enables photographers to collect credentials for their photos and assert ownership to third parties in a privacy-preserving manner. We describe a proof-of-concept implementation using the Hyperledger Aries SSI library, which can be extended for real-world deployment. We also discuss the potential for scaling this implementation.
