A computer system and method for storage and retrieval of encrypted biometric data which includes a biometric data intake device that selectively intakes original biometric data from a user and communicates with a biometric data management system. The biometric data management system has a resident data storage or a remote storage in communication therewith for the selective storage and retrieval of the encrypted biometric data. The system and method allow a user to originally encrypt biometric data such that the user solely possesses one of the necessary keys for later decryption of the stored and encrypted biometric data. The system and method will then doubly encrypt and store the user's biometric data in such a secure manner that the data can be stored on a public blockchain architecture, if desired. Full decryption of the original user biometric data for identity verification can only be performed with access to the user key.
