Abstract

PURPOSE:To eliminate the possibility that transaction evidence is left at either side of parties concerned in a transaction by providing an auxiliary recording means that records information from which it is judged whether or not the contents recorded on the recording means of one side are effective to the other side. CONSTITUTION:A transaction side C sends a transaction message (d) to a transmitter and receiver 6 in code which is not decoded at a side D ant the message is recorded on a recorder 7. Then, the side D returns an answer message (e) to a transmitter and receiver 6 and if the contents of the message (e) contradict the message (d) of if the transaction is canceled at this time, the message (e) is not recorded on a recorder 8. Then, the transaction number and judgement result of the transaction are recorded on the auxiliary recorder 9 independent of the recorder 8 in code which is not decoded at the side C through a converter 10 regardless of whether the message (e) is recorded or not. Said judgement result is transmitted to the side D as a message (f) which requesting the execution or erasure of the message (d). Therefore, the record proving that the message (d) is ineffective is left even if the message (d) on the recorder 7 is not erased although the message (f) for requesting the invalidation of the transaction is sent from the side C.

By the way, records of these transactions are recorded on the recording means of both parties with digital signatures that record "a code that allows the other party to determine the content, but it is impossible to create the content itself." This is carried out using a cryptographic method called JP-A No. 56-87959 (for example).

In the transmitting/receiving device of the present invention, whether or not the message C is recorded on the recorder 8 of the sender side C, the auxiliary recorder 9 provided independently of the recorder 8 records the message C. The information that specifies the transaction (for example, transaction number) and the transaction determination result are converted by the converter 10 into "a code that cannot be generated on the transaction side C" (described later) and are recorded.

In other words, in order for a transaction to be executed or canceled on the transaction side, a judgment result signal i from the transaction side C is required.
It is necessary to receive the message ")," but this signal can only be generated by the cryptographic processing section 13 in the auxiliary recording device P of the transaction side C. Moreover, the judgment result signal i is transmitted at the same time as the judgment result signal i. Since the transaction records stored in the signal 14 and later recorded in the recorder 7 on the trader's side serve as evidence for determining whether or not they are valid, there is no possibility that records will be left on the trader's side against the wishes of the trader C. Even if you do so, no trouble will occur.
