Abstract

PURPOSE:To maintain a data and to secure security of the data by defining control information and a transfer data in a transfer management file as one transfer unit information and exchanging the information between a transfer start side and a transfer reply side before and after the transfer of the file. CONSTITUTION:Sender/receiver confirmation information, security information and transfer mode information or the like are set to a transfer management file 11 in advance. A file transfer section 16 makes data exchange according to the transfer management file 11. When all the data exchange is finished, the reception processing of the transfer management file of the destination relating to transfer management file items of the transfer management and start side is implemented. The transfer start side file transfer section 16 uses the information of the transfer management file (start side) 11 whose transfer state is set and a received transfer management file (reply side) 15 to confirm whether or not the transfer is correctly implemented. Thus, the maintenance of the data subjected to text exchange is ensured and the security of data is ensured.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to business protocols stipulated when exchanging online data using computers, and particularly relates to system operation rules and rules for some information transmission methods. This invention relates to a file transfer procedure method that is implemented using the OSI protocol.

[Conventional technology]

Conventionally, as this type of procedure, there are the JCA procedure and the gold-silver procedure, which are existing industry procedures as rules (transmission procedures) for information transmission methods. For details on the JCA procedure and gold/silver procedure, refer to the AJ Job Information Online Data Exchange System published by the Ministry of International Trade and Industry and the "Japan Bankers Association Standard Communication Protocol" published by the Japanese Federation of Bankers Associations. In these procedures, when exchanging data, transaction data and procedure control information were to be sent in separate telegrams called data telegrams and control telegrams.

[Problem to be solved by the invention]

Existing industry procedures such as the above-mentioned conventional 1JCA procedure and gold/silver procedure t exchange data by distinguishing messages into control messages and data messages. For this reason, the integrity of data exchanged using data telegrams cannot be ensured, and data security is difficult to protect. In addition, the procedure information exchanged on the control message is a procedure that emphasizes control regarding information items necessary for transmission control and destination information that can be obtained through mutual information exchange. The disadvantage was that information could not be exchanged. Furthermore, when transferring multiple files, there is no message to exchange file information all at once in advance, and the data is exchanged serially one file at a time. The disadvantage is that it is not possible to obtain information to determine whether the transfer time will be the same.

[Means to solve the problem]

The file transfer procedure method of the present invention, before starting actual file transfer, performs actual data exchange with a processing unit that exchanges a transfer management file that holds operational information items necessary for overall control/management of file transfer. The starting side includes a file transfer section and a transfer section that exchanges data.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

Referring to FIG. 1, which shows the flow on the startup side of the file transfer procedure method that is an embodiment of the present invention, one embodiment of the present invention includes a transfer management file exchange processing unit 1, a file transfer unit 2, and a transfer management file and a reception processing section 3.

Referring to FIG. 1 and FIG. 2, the transfer management file exchange processing unit 1 receives confirmation information of the party/other party set in advance in the transfer management file 11.

By exchanging security information and transfer mote information, confirm in advance whether it is okay to transfer files, what kind of file transfer will be performed, and the files to be exchanged (referred to as transfer files 12.13).
Obtain information on whether the specifications are as follows and how many cases there are.

In the file transfer unit 2, data is actually exchanged according to the transfer management file 11. The file transfer section 2 is
When data is exchanged, the transfer status is set as transfer status information in the transfer management file 11, and statistical information at the time of transfer is also set.

When all data exchange is completed, the transfer management file reception processing unit 3 performs a process of receiving the transfer management file of the other party for the transfer management file item of the initiating side. The file transfer unit 2 on the startup side transfers the transfer management file (startup side) 11 whose transfer status is set and the transfer management file reception processing unit 3.
It is determined whether there is any contradiction in the information with the transfer management file (response side) 15 received at , and whether the transfer status was normal, and it is determined whether the transfer was performed correctly.

Referring to Figure 3, which shows the structure of the transfer management file, when multiple files are transferred in one file transfer, the transfer management file is a transfer unit that indicates the unit in which multiple files are transferred without any break. Data having the structure shown in FIG. 3 is created for each unit. Items related to overall control/management of transfer units in the transfer management file store confirmation information, security information, transfer mode information, etc. for transfer files, and information related to transfer files, transfer mode information, etc. are stored in the operation items of transfer file n. Status information, transfer statistics information, etc. are stored.

Next, the operation of one embodiment of the present invention will be explained in detail with reference to FIG. When this procedure is used, the difference between the initiating side 1 and the responding side 2 shown in FIG. 2 is step 3, that is, the processing performed by the transfer management file reception processing section 3 shown in FIG.

Referring to FIG. 2, a transfer management file storing definition information of transfer units defined before file transfer is exchanged. In this case, when the transfer file is sent from the initiator to the responder (this is called transfer mode), and when the transfer file is sent from the responder to the initiator (this is called collation mode), the transfer file is activated. The exchange format of the transfer management file differs depending on the three cases in which files are sent in a mixed manner from the side to the responding side and from the responding side to the invoking side (this is called a mixed mode). In the case of transfer mode, the contents of the transfer management file 11 on the initiator side are sent to the transfer management file 21 on the responder side.9 In the case of inquiry mode, the contents of the transfer management file 21 on the responder side are sent to the transfer management file 21 on the initiator side. Sent to 11. In mixed mode, transfer management file 1 on the initiating side
1 is sent to the transfer management file 21 on the responding side, necessary information is set on the responding side, and then sent back from the responding side to the transfer management file 11 on the initiating side.

In step 2 in FIG. 2, if the transfer mode is selected, the data in the transfer file 12 is transferred to the transfer file 22, and the transfer status is set in the transfer management file 14 by the file transfer unit 16. Similarly, the data in the transfer file 13 is transferred to the transfer file 23, and the transfer status is set in the transfer management file 14 by the file transfer unit 16. In the file transfer section 25,
Transfer state information of the transfer file 22 and transfer file 23 is set in the transfer management file 24.

Note that in FIG. 2, the transfer management file 17 and the transfer management file 14 are the same and are described to express that file items are updated by file transfer. Similarly, the transfer management file 21 and transfer management file 24 on the responding side are also the same. In step 3, the transfer management file 24 on the responding side is transferred to the transfer management file 15 on the initiating side. Note that in the file transfer of the transfer management file, the transfer unit is only information. This is done by checking the information about the amount of one transfer with the file 15.

If necessary, the procedure repeats the process from step 1 again.

2. Effects of the Invention] As explained above, the present invention overcomes the conventional existing industry procedure (J
CA procedure, gold/silver procedure), control information and transfer data were not clearly separated in the procedure in the message, so it was defined as 1 transfer amount information in the transfer management file, and the information before and after file transfer (data exchange) By exchanging data between the initiating side and the responding side, data exchange data can be separated from control information, and data can be maintained and security protected. Furthermore, by setting operational information in the file item of this transfer management file, there is an effect that more operational information can be exchanged. Also, by exchanging predefined items for the entire file transfer,
This has the effect of being able to predict the entire file transfer process in advance.
