Decentralized Humanitarian Aid Distribution : Leveraging Multi-claim Proofs for Secure and Transparent Multi-location Delivery

Abstract

In the evolving landscape of humanitarian aid, the demand for efficient and secure distribution systems has become increasingly critical. Traditional centralized digital aid systems, commonly employed in humanitarian operations, often collect extensive data on beneficiaries. This centralization poses significant privacy and security risks, particularly for vulnerable populations in conflict-affected regions who rely on humanitarian assistance. In response to these challenges, this thesis proposes a novel approach to aid distribution by leveraging decentralized identity management solutions, which empower beneficiaries with greater control over their personal information, regardless of socio-economic status or background.

The research method is grounded in a Systematic Literature Review (SLR), which identifies and analyses relevant studies, theoretical frameworks, and existing gaps within the field. Qualitative analysis of the conventional single-location distribution paradigm was conducted to develop an up-scaled, multi-location system that utilizes smartphone tokens and a QR code-based presence tracing interface. This presence tracing application simplifies the tracking of aid disbursement across multiple stations, effectively preventing multiple claims by the same individual. Concurrently, visit records of beneficiaries to distribution sites are securely stored on their personal devices, thereby enhancing data ownership and control. The proposed system efficiently manages aid distribution, providing real-time updates and verifiable audit trails.

This thesis significantly contributes to the advancement of decentralized, privacy-enhancing aid distribution systems. By offering a practical solution tailored for humanitarian operations, the system ensures that humanitarian assistance reaches those in need more effectively.
