Blockchain-Based Access-Control System for Unused Medicine and Organ Donation Using Enhanced Hybrid Cryptography
D Divyashree, Chitra Ravi · 2023
Unused medicines and organ donations have been critical concern in healthcare organizations. However, the current process of accessing unused medicines and organ donations are often inefficient, prone to errors, and lack of transparency. Blockchain-Based Access-Control (BBAC) system is proposed in the system for organ donation and unused medicine, integrating with enriched hybrid cryptography using Enriched Elliptic Curve Cryptography (ECC+) algorithm and the Enriched Blowfish Cryptography (EBC) algorithm. The methodology of the proposed BBAC system involves creating a decentralized database of unused medicines and organs maintained through a secure and transparent access-control system. Access to the database is controlled through an enhanced hybrid cryptography system using ECC+ algorithm and the EBC algorithm to ensure maximum security and privacy. The stakeholders are provided with up-to-date information on the availability of organs and unused medicine on the database in a real-time. The outcome of the proposed Blockchain-Based Access-Control (BBAC) system determines significant progress in accessing the organs and unused medicine. The enriched hybrid cryptography of the system results in uppermost throughput of 80.28%, equated to preceding AES-ECC, AES-RSA and RSA-ECC cryptography groupings with several data types. Additionally, the BBAC system takes less time to execute compared to previous systems.
