Abstract

Highlighting the diverse applications, from real-time patient monitoring to pharmaceutical advancements, blockchain technology brings a transformative impact to the healthcare sector. This research explores the integration of the "Digital Medical Wallet" System with Malleable Blockchain to revolutionize healthcare data management, particularly focusing on multimedia image data. Employing the Chameleon Hash Algorithm for privacy and integrity, the study compares its performance with Traditional Hashing and evaluates modifiable versus classical blockchains. Simulations reveal trade-offs between execution time and privacy preservation for hashing methods, and scalability versus energy consumption for blockchain types. Results suggest Chameleon Hashing enhances privacy but incurs higher computational costs, while malleable blockchains offer scalability at the expense of complexity and energy usage. These findings provide actionable insights for designing secure and efficient healthcare data systems, balancing privacy, efficiency, and scalability for improved patient care and healthcare efficiency, especially in handling multimedia image data.
