A Study on PDS-Based Contract Management for Decentralized Contract Services

We propose a method to enhance the security and transparency of contract management systems using a decentralized Personal Data Store (PDS).Decentralized data management is gaining attention as an effective alternative to address issues related to data security, single points of failure, and data sovereignty in traditional centralized contract management systems.We utilize Solid Project-based PDS to store and manage contract data, granting users ownership and control over their data through a designed contract management structure.We focus on providing a mechanism for users to control access to contract data through Solid Project's Web Access Control (WAC) and ensure the integrity and transparency of contract execution by incorporating blockchain technology.We demonstrate that a decentralized contract management system can enhance user-centered data ownership and improve privacy and security throughout the contract process.
