An electronic signature (e-signature) is a traceable e-mail or a biometric applied to a message. The biometric may be based on digitized handwriting (handwriting that is converted by cryptography into a digital signature) or a biometric (e.g., a fingerprint that can be combined with a hash or digest of the message to show the signer’s intent). The electronic signature cannot be removed and applied to other documents to forge a signature.
