Smart Contract-based Consent Management System for Data Privacy Protection

The PDPA laws are the first data privacy laws to protect all Thai citizens since 2018. The consent management system (CMS) is a core module of Thailand’s PDPA laws. It maintains complex and dynamic contents of user consent which are updated and changed all the time. The best network that can store a CMS’s historical data is blockchain while the best tool for maintaining it is a smart contract which works on Ethereum-based blockchain. This paper aims to apply the Smart contract technique to enhance a consent management system to perform a better data privacy service. This research paper proposes a Smart Contract-Based Consent Management System (SCCMS) as an innovative solution to enhance data privacy protection. By leveraging blockchain technology and smart contracts, the SCCMS aims to provide a transparent, secure, and decentralized framework for managing user consent, thereby ensuring greater control and transparency in the handling of personal data. Our experiment result outperforms a regular CMS system
