Description
Summary:In early 2020, World Health Organization (WHO) declared that the world is facing the COVID-19 pandemic. This pandemic is caused by the emergence of a new type of coronavirus which spreads very quickly. Because of this pandemic, the government has issued health protocols that use a lot of COVID-19 tests. However, cases of forgery of test certificates often occur in paper-based test certificate. To overcome this problem, we propose a COVID-19 test certificate management system using blockchain technology. By using blockchain technology, the system can be used by multiple entities, even though the entities that use it do not have trust relationship beforehand. This is possible because blockchain is a technology that uses a decentralized network that can store its data with a secure consensus mechanism. The system built using the Ethereum platform, which is a public non-permissioned blockchain that supports decentralized application development through smart contracts that executed via EVM (Ethereum Virtual Machine). The system has been developed using 3-layers architecture, which contains network, software, and application layer. The evaluation shows that the system successfully fulfills the COVID-19 test certificate management requirement. The system can be used for tester registration, and create, revoke, display certificates. Furthermore, by using encryption and digital signature mechanism, the system can protect patient privacy and data integrity. The system has also succeeded in fulfilling the availability and security requirements. However, due to the nature of Ethereum consensus mechanism, the system has much lower response time, compared to the centralized counterpart.
