Anonymous, Secure, Traceable, and Efficient Decentralized Digital Forensics

Digital forensics is crucial to fight crimes around the world. Decentralized Digital Forensics (DDF) promotes it to another level by channeling the power of blockchain into digital investigations. In this work, we focus on the privacy and security of DDF. Our motivations arise from (1) how to track an anonymous- and-malicious data user who...

WebDSL: Linguistic Abstractions for Web Programming

Information systems store and organize data, and manage business processes concerned with that data. Information systems aim to support operations, management and decision-making in organizations. Web applications are ideal for implementing information systems. Although existing web frameworks provide abstractions for creating web applications,...

Aligning stakeholder interests, governance requirements and blockchain design in business and government information sharing

Governance requirements for systems supporting information sharing be-tween businesses and government organisations (B&G) are determined by a high variety of stakeholders with often conflicting interests. These conflict-ing interests can hamper the introduction and scaling-up of ICT-innovations that change their roles and authorities. We...

System Impacts of User Scheduling with Minimal Angular Separation Constraints in Radio Resource Management for 5G and Beyond

The system effects and trade-offs of varying the minimal angular separation among multiple simultaneous co-frequency users are investigated for a high-capacity multibeam communication scenario. Through the statistical system simulations, it is demonstrated that the optimal (non-zero) value of the required separation depends on the base station...
