Description

Method and System for Product History Management Using a Blockchain-Based Platform as a Service The present invention relates to a product history management system and method using blockchain technology, and more specifically, to a system and method capable of safely and efficiently managing the history of the entire process from production, distribution, recycling, and disposal of a product using a Blockchain as a Service (BaaS) based platform. Blockchain is a distributed ledger technology that guarantees the transparency and integrity of transaction records. Because blockchain publicly manages transaction records over network communication and verifies them using a decentralized consensus mechanism, tampering by third parties becomes virtually impossible, making it highly effective for verifying the accuracy of transactions and enhancing security. Through these characteristics, blockchain provides transparency and reliability, and can be used for verifying the security and trust of transactions occurring on the network. For this reason, blockchain technology is being utilized in various fields, such as financial services, supply chain management, and digital identity authentication. For instance, in financial services, this technology is used to enhance transaction transparency, while in digital identity authentication, it plays a crucial role in protecting personal information. Furthermore, recently, Blockchain as a Service (BaaS) cloud computing platforms are being utilized to build and host blockchain infrastructure using cloud computing solutions. Recently, transparency and traceability regarding the entire process from product production to disposal have become increasingly important. In particular, the importance of product history management is growing in sectors such as food, pharmaceuticals, and high-value goods for purposes such as preventing counterfeiting, ensuring quality, and verifying ethical production. However, existing centralized systems have struggled to manage reliable information within complex supply chains involving multiple stakeholders. Blockchain technology is attracting attention as a suitable solution for product history management because it can guarantee data integrity and reliability through its decentralized structure and encryption technology. Meanwhile, Decentralized Identifier (DID) technology is bringing innovation to identity management by combining with blockchain technology. Decentralized Identifier enables the creation and management of identities in a decentralized manner without a centralized registration authority. This allows individuals, organizations, and even objects to manage their own identities, thereby returning data sovereignty to the user. Current blockchain-based product history management systems have various problems, such as reduced system processing speed, data privacy issues, and implementation complexity.
