Witness system

Abstract

A witness system using EDI (electronic data interchange) to perform efficient distribution and account settlement processes between selling and buying companies. A buying company makes documents according to delivery or order vouchers, and electronically sends the documents to a selling company via a notarization authority. The selling company compares the authentication documents with delivery or order vouchers the selling company issued, and, after determining that the documents are correct, executes a confirmation response to the notarization authority. The notarization authority registers the documents in the witness server's receipts detail table and notifies the buying and selling companies that the notarization authority authenticated the documents. This structure enables the making of accurate detailed payment statements when, for example, a detailed payment statement is made or a funds transfer is executed based on confirmed data. Furthermore, checking the detailed payment statement is made simpler through reference to the witness system server.

1 . A method of exchanging sales data between a buyer and a seller using a witness system, comprising:
 transmitting a confirmation document to the witness system from a buyer in response to receipt of seller records corresponding to sold items delivered by a seller, the confirmation document indicating a selected sale and corresponding sales data among seller records received by the buyer;   automatically determining delivery vouchers of the seller corresponding to the selected sale of the seller records included in the confirmation document; and   authenticating the confirmation document with the delivery vouchers of the seller via the witness system.   
   
   
       2 . A method of exchanging sales data between a buyer and a seller using a witness system, comprising:
 enabling the buyer to select a single sale record including corresponding sales data of at least one item from seller records of sold items delivered by the seller and creating a confirmation document including the single sale record; and   automatically determining delivery vouchers of the seller corresponding to the selected single sale record in the confirmation document and authenticating the confirmation document based on a comparison of the delivery vouchers with the confirmation document via the witness system.
