All personal information such as identity, biometrics, and access information can be written to and read from the database in an encrypted way thanks to the integration of BioAffix OneServer with HSM (Hardware Security Module). All data to be used by the BioAffix product family for access and verification processes become impossible to be listened to and read from outside, by going through advanced, up-to-date, and high-security cryptography processes during the writing and reading. In this way, encrypted data with HSM cannot be read by a third person including IT staff under any circumstances.
