Tamper-Resistance is the raising of an explicit alert should the Digital Signature be compromised. The compromise could be with respect to the document contents, and/or the identity of the Signer, and/or the timestamp of the Digital Signature. At a minimum, this requires the visual display or audio communication of a prominent and explicit message stating that the Digital Signature is no longer valid.
