Abstract
A method and apparatus for transaction verification is provided. An acoustic signature of a transaction executioner is captured and electronically saved as a digital signature file. The digital signature file is associated with the transaction and then sent to a central location for storage. The transaction may be verified by reproducing the acoustic signature file from the digital signature file and acoustically verified by parties interested in verifying the transaction.
