    encrypting the encrypted first cryptographic key with a second cryptographic key;

    determining that the occurrence of a PII data disassociation event associated with the second cryptographic key has occurred; and

    rendering the PII data inaccessible by disassociating the second cryptographic key from the encrypted first cryptographic key.
