Blockchain applications in drug data records

Abstract

Blockchain is a data storage technique in the form of blocks where the hash system and blocks that cannot be manipulated make blockchain suitable for storing important data. One of them is drug data, where currently in drug data, data manipulation often occurs which leads to drug counterfeiting. From previous research, blockchain in the medical world has been applied in storing patient history by utilizing smart contracts. Goals of blockchain application, drug data from manufacturers can be directly viewed and purchased by buyers. The research more towards innovation, blockchain as a database for storing drug data. Ethereum blockchain can be implemented and stored data can be well integrated with Smart Contract. The existence of smart contracts that support and facilitate transactions between producers and buyers. To maintain data security, system will be implementing access permissions in smart contracts to maintain data integrity and security. Eventually maintaining privacy, decentralization, transparency, and authentication in drug data and every drug transaction can be implemented properly.
