Hyperledger Fabric: A permissioned blockchain solution for superior data privacy

Permissioned blockchains like Hyperledger Fabric have ensured compliance with core GDPR (General Data Protection Regulation) principles concerning privacy, confidentiality and integrity of data and features such as ‘right to be forgotten’. Here’s how:

  • Consent on data collection and processing - The number of stake holders required for user consent for data processing is more in the permissioned blockchain setting and hence, the level of complexity to ensure compliance has increased.
  • Privacy, confidentiality and integrity - Permissioned blockchains rely on encryption and pseudonymous identities to adhere to GDPR properties such as the unlinkability of transactions, anonymity of users, and confidentiality of transactions.
  • Data minimization and purpose limitation - Privacy by Design mandates only and necessary data transaction, which is vital in ensuring data privacy across applications. Permissioned blockchains like Hyperledger Fabric have features that enable ‘right to be forgotten’.
