We've discussed this in the office. The outcome being that we would not store personal information within a blockchain. Instead we'd keep the personal data in a secondary platform and use an anynomised ID within the chain. Personal data remains able to be updated. We would need to manage orphan IDs in the chain if the personal data needs to be removed. Of course this all supposes that it's not the persnoal data that you are attempting to make tamper proof.
