摘要: 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.
