| dc.description.abstract | Blockchain technology has been a highly regarded innovation in recent years, valued for its decentralized, secure, and transparent characteristics. It has been widely adopted in various sectors such as finance, supply chain, healthcare, and has brought significant changes and innovations in these fields.
The research objective of this paper is to explore the application architecture of blockchain technology in the electricity billing system. In Taiwan, the deployment of smart meters is increasing, enabling the automatic collection and transmission of electricity usage data. However, there are risks of data tampering and unauthorized use during the data transmission process. To address these issues, this paper proposes an architecture based on blockchain and IPFS (InterPlanetary File System) to provide a more secure solution, ensuring data integrity and preventing tampering.In this architecture, the documents at the smart meter end are encrypted using an asymmetric encryption method to ensure their security, and the encrypted files are stored in the IPFS system. The power operator obtains the required data from the blockchain to generate electricity bills.To assess the system′s performance, a multi-file upload test was conducted at the smart meter end, recording the processing time for uploading different quantities of files. The test results revealed that the main factors affecting the time were the delays caused by IPFS uploads and the interaction time with the blockchain, providing a better understanding of the system′s performance. | en_US |
