A process of encrypting an object having an associated object tag includes generating a cryptographic key by binding an organization split, a maintenance split, a random split, and at least one label split (710). A cryptographic algorithm is initialized with the cryptographic key, and the object is encrypted using the cryptographic algorithm (712) according to the object tag, to form an encrypted object. Combiner data is added to the encrypted object (711). The combiner data includes reference data, name data, a maintenance split or a maintenance level, and the random split (710). Alternatively, key splits are bound to generate a cryptographic key, and a cryptographic algorithm is initialized with the cryptographic key. The initialized cryptographic algorithm is applied to the object according to a cryptographic scheme determined by the object tag, to form an encrypted object. One of the key splits corresponds to a biometric measurement.
