People are reluctant to provide their personal data, making it difficult for corporations to collect such information. The Personal Data Market presents a promising solution to this problem, but current offerings must overcome several challenges. This paper proposes a Blockchain-based Data Market framework, “Decentralized Data Marketplace for Digital Me”, in which personal data are anonymized in accordance with the General Data Protection Regulation to protect the owner's privacy. In addition, this paper presents a user scenario for the framework in the form of Financial Me, which provides a reasonable price range and adequate incentives for data quality.
