Abstract
A process of cryptographically securing a data object including one or more respectively tagged data elements includes selecting a tagged data element from among a plurality of tagged data elements, based on an associated data tag. A plurality of cryptographic key splits is generated from seed data. The cryptographic key splits are bound together to produce a first cryptographic key. A second cryptographic key is generated based on security requirements of the data object. The tagged data element is encrypted using the first cryptographic key. The data object encrypting using the second cryptographic key. At least one of the cryptographic key splits is based on the associated data tag.
