Abstract
Methods and device for digitally signing documents by using a portable device that encodes a signature string to sound. The acoustic signature string may be transmitted and then decoded back into digital data. The signature string may be further processed to verify the signature of the document and to produce a certificate of identity and integrity for the document. The certificate of identity and integrity may be used to further identify and validate the document and its signer.
