By employing a procedure that uses data elements that change for each record the resulting ciphertext will be unique. As an example if the
same value, key, and encryption are used for a value in a record the resulting ciphertext will be identical. Someone knowing the value of
one of the records independent of the ciphertext can by inference know the value of other records that display the same ciphertext.
Level 2, Not Scorable
NOTE: Please review the benchmark to ensure target compliance.as manual verification is required in order to determine which elements require an encryption key.
