Thanks for the reply! I was actually thinking about ways to introduce blockchain as a step in maximizing the security of traditional systems. For example if there was a blockchain layer of security that would require a valid transaction to be made to a unique address to then enable one to get access to a unique one time key that allows one to access encrypted information regarding credit history or PII it would be a much better system. At the end of the day I think the security did not reflect the confidentiality of the information that was being stored and that's what led to the breach.
