A method and system for securely recording a verbal transaction, the method including
the steps of recording an offer and an acceptance of the transaction as a digital
audio file, generating a voice security token from the recorded digital audio file,
and providing the generated voice security token to a buyer and/or a seller, wherein
the voice security token provides authentication of the transaction. The voice
security token is generated by sampling audio frequency and intensity set of the
recorded digital audio file and converting the sampled information from a current
time domain spectrum to a frequency domain spectrum to condense the sampled information.
Finally, a digital file is generated from the condensed information, and encrypted
to produce the voice security token.
