The Signature Key

When the signature is first created, a signature key is calculated from the signature and stored. When the signature is verified, this key is recalculated from the current signature and compared to the stored key. If the two keys do not match, the signature key checksum fails. A failed checksum indicates that the current signature has been altered since the time of capture. If the checksum fails, the signature is not displayed in the Signature Audit Administration view.
