In recent years, vaccine safety incidents have occurred frequently. To protect vaccine safety, researchers
have proposed to use blockchain to secure the vaccine circulation process. Technically, blockchain has
some limitations in solving vaccine and other supply chain problems, such as large on-chain storage
consumption and low throughput. To better alleviate these restrictions, we propose an improved,
blockchain based, storage-efficient vaccine safety protection scheme in this work. Specifically, we
first model the vaccine circulation process. We then design a system to protect vaccine circulation
using blockchain, cloud, and cryptographic mechanisms. The proposed system leverages the cloud to
implement the vaccine circulation model.Correspondingly, it uses the blockchain to store circulating data
certificates and signatures.We evaluated the proposed conceptual model using a consortium blockchain.
The experimental results show that the proposed system is efficient. Three core cryptographic algorithms
to secure the immutable vaccine supply and location platform. SHA-256 is used to generate tamperproof
hashes for all vaccine records, ensuring data integrity on the blockchain. AES encrypts sensitive
vaccine information to maintain confidentiality during storage and transmission. CP-ABE enables finegrained,
attribute-based access control so that only authorized users can decrypt and view protected
data. Together, these algorithms ensure a secure, trustworthy, and decentralized vaccine management
solution developed using Java and blockchain technology.
