Paper: Using blockchain to store personal information: a systematic literature review
Abstract: Blockchain has been gaining significant interest in several domains. However, although this technology is valuable in many cases, blockchain also raises relevant challenges. Data protection is also an increasingly important subject. In particular, after GDPR was published, companies worldwide change the way they process personal data. The objective of this systematic literature review is to examine the usage of blockchain for storing personal data. The review focuses on the advantages and challenges of storing personal data in a blockchain, as well as techniques and technologies for storing personal data using blockchain.

Abstract: The immutability of data stored in a blockchain is a crucial pillar of trust in this technology, which has led to its increasing adoption in various use cases. However, there are situations where the inability to change or delete data may be illegal. European Union’s General Data Protection Regulation (GDPR)—applying to any company processing personal data from European citizens—explicitly entitles individuals to the right to rectification and the right to be forgotten. In this paper, we describe the design of a system to deploy and process survey data in a GDPR-compliant manner. It combines an Hyperledger Fabric blockchain to ensure that data cannot be tampered with and InterPlanetary File Systems (IPFS) for storage. With the proposed arrangement, we reap several security benefits enabled by blockchain’s immutability without running afoul of the regulations. Furthermore, the proof-of-concept is generic and can easily be adapted to various domains.
