Abstract: A system receives, from a patient, first biometric data associated with a first biometric data type and second biometric data associated with a second biometric data type and generates a cryptographic hash of the first biometric data and the second biometric data. The system records the biometric numeric score on a blockchain network. The system receives protected health information for the patient and generates a protected health information numeric score based on the protected health information for the patient. The system records the protected health information numeric score on the blockchain network, receives encrypted patient credentials, records the encrypted patient credentials on the blockchain network and generates a master cryptographic hash based at least in part on the recorded biometric numeric score. The system validates, via a validation module including a smart contract operating on the blockchain network, the patient credentials.
