Towards a Secure Central Bank Digital Currency System: A Case Study of Tanzania
The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.This study proposes a secure, context‐specific design for a Central Bank Digital Currency (CBDC) system for Tanzania, grounded in stakeholder input and empirical data. It identifies key adoption barriers in digital financial services, namely, security and privacy concerns and high transaction fees, and suggests how a well‐designed CBDC might address ...

Spoofing and Anti-Spoofing with Wax Figure Faces
CoRR, 2019 We have witnessed rapid advances in both face presentation attack models and presentation attack detection (PAD) in recent years. Compared to widely studied 2D face presentation attacks (e.g. printed photos and video replays), 3D face presentation attacks are more challenging because face recognition systems (FRS) is more easily confused by the 3D ...
