As the COVID-19 pandemic has been raging since 2020, it has had serious impact on the economy, society and many aspects of the world. In order to slow down the rapid spread of the virus, governments or organizations are committed to finding solutions. Contact tracing is one of the common methods to reduce the number of confirmed cases. However, the existing contact tracing systems usually require users to upload data by themselves, and does not automatically compare contact data or send notification. This will greatly decrease the convenience for users.
This thesis proposes an automatic contact tracing and alerting system based on blockchain technology, hoping to provide automatic notification as well as protect user’s privacy. In our proposed system, we use the characteristics of blockchain such as data anonymity and data transparency. We stored users’ private data anonymously and use smart contracts to interact with blockchain ledger and server. Finally, we also did prototype implementation and performance analysis of the proposed system to ensure the actual usability of the system.
