Further, the device of the trading support / management server 4 may be provided integrally with the device of the manager terminal 3 so as to share the function of transmission / reception processing on the network 5. In the following description, an example in which the function of the administrator terminal 3 functions as a part of the trading support / management server 4 will be described for convenience.

Each of the computers 1a, 2a, 3a, 4a is constituted by a computer, and executes a trading support processing program recorded in a storage medium such as a ROM to execute various trading operations required at each terminal. Execute the process. In particular, the computer 4a provided in the trading support / management server 4 centrally processes transmission and reception of various types of information between the seller terminal 1 and the buyer terminal 2, and controls a series of processes related to sales and purchase.

Next, a description will be given of a procedure of the trading support process according to the above configuration. In the trading support processing, on the environment of the open network 5 such as the Internet, a combination of sales information and a sales person and a purchaser is created, and operations from the conclusion of the sales (provisional decision) are executed. FIG. 2 is a flowchart showing the procedure of the sales support processing executed by the seller terminal 1, FIGS. 3 to 5 show the procedures of the sales support processing executed by the sales support / management server 4, and FIG. 6 shows the purchase executed by the buyer terminal. It is a flowchart which shows the procedure of a support process.

It is necessary for both the seller and the purchaser to notify the manager of the settlement report, company profile, and other information requested by the manager in advance to obtain the user number and the security key file. At this time, the trading support / management server 4 encrypts participant information and a part of subsequent participant transaction information to form a participant information file, and associates the participant information file with a security key file for each participant. . This participant information file is updated every time a participant conducts a transaction, and also includes a problem occurring in the transaction. The administrator can check this file and, if it is found that the content violates a predetermined operating rule obtained with the consent of the participant, the administrator can suppress the participation of the participant. Encryption is performed using wavelet transform technology. The information to be encrypted is first converted into a numerical sequence based on a conversion table or the like for each content.

Next, the order of each numerical value sequence is changed according to a predetermined rule. Finally, they are combined by reconstructing the wavelet technology, and finally converted into one numerical sequence. The feature of this encryption is that each value on the numerical sequence corresponds to a character on a one-to-one basis, and includes a complicated conversion inside. Decryption is performed by first performing the wavelet transform decomposition on the numerical sequence, returning the numerical order of the obtained multiple numerical sequences to the original, and converting each of the obtained numerical sequences to a character in a correspondence table, it can. The same encryption is performed on files that need to be encrypted in the trading support process.

[When the seller makes a sales request (sales application) first] When the seller owns a product to be sold,
The seller uses the seller terminal 1 to connect to the network 5
Then, the user number and purpose sent by mail or fax from the manager of the book trading support system are input and transmitted (S1). As the purpose, one of the purposes such as sales, purchase, purchase outside the sales lot, and sales outside the sales lot is selected. In this case, select sales. Further, the security key file sent by mail from the administrator is input. This security key file has a large number of numbers arranged therein, and this number sequence is automatically converted by the trading support / management server 4 to recognize participants and give permission for participation. is there. As the conversion means, simple analysis, advanced analysis techniques such as Fourier transform and wavelet transform are applied.

The trading support / management server 4 recognizes the seller based on the user number and the security key file sent from the seller terminal (T1), and permits the seller to participate in trading (T1-OK). Then, an authentication screen relating to the purchase and sale (see FIG. 7) is sent to the seller, and a user code number (transaction recognition information) and an input screen are provided via the network 5 (T2). This input screen (see FIG. 8) is displayed on the seller terminal 1 (S
2) The seller can input desired sales information (product name, sales amount, delivery place, sales date, minimum price, payment method, etc.) in each of predetermined columns in a predetermined format (S).
3). The sales request information is transmitted to the trading support / management server 4 via the network 5 after being input.

After confirming the reception, the trading support / management server 4 automatically transmits the purchase reservation acceptance period and the lot number to the seller (T3). In addition, a file (sales file) is input from the seller terminal 1 to input the desired sales information to which the user code number, purchase reservation acceptance period and lot number are added, and the file number is associated with the lot number (T4, FIG. 9). . In addition, the buyer is the buyer terminal 2
This sales file can be accessed using (T5).

At this time, the buyer first inputs the user number, the purpose (purchase) and the security key file (K1) in the same manner as the seller (K1), and obtains permission for recognition and participation from the trading support / management server 4. Upon permitting the participation (T5-OK), the trading support / management server 4 gives the buyer a list of the user code numbers related to the trading, the lot numbers for which the purchase is being accepted at that time, and the respective product names ( The sales desire information (see FIG. 10) is provided to the buyer terminal 2 through the network 5 (T6, T7).

The buyer terminal 2 transmits a lot number for which detailed information is to be confirmed based on the provided sales desire information (K2) (K3). As a result, from the sales support / management server 4, among the sales files corresponding to the lot numbers, information (sales file, see FIG. 11) necessary for purchasing decision is provided through the network (T 8,
K4).

If there is a will to purchase after confirming the contents, the purchaser's terminal 2 displays the intention of the purchase action and inputs and sends the lot number of the purchase target (K5). The sales support / management server 4 confirms the reception, confirms the desired purchase lot number (T9), and automatically provides an input screen for purchase to the purchase terminal 2 via the network 5 (T9).
10, K6). Using this input screen (see FIG. 12),
In the buyer terminal 2, the purchase request information (purchase amount,
The purchase price above the lowest price specified by the seller can be entered. After inputting these conditions, the buyer terminal 2 transmits all the inputs including the purchase request information to the sales support / management server 4 using the network 5 (K
7).

The sales support / management server 4 confirms the reception, and when it is confirmed that the purchase is within the purchase acceptance period (T11-O).
K), all information is added to the purchase request file corresponding to the lot number (T12). The purchase acceptance period is set in advance, and when the purchase acceptance period ends (T13-
OK), the manager automatically classifies the desired files and ranks the purchases according to the priorities determined in advance by both the seller and the purchaser (T1).
4). The priorities are set in advance in consideration of the participant's desire, for example, in the order of the desired purchase price with respect to the lowest price of the sale, or in the order of the desired purchase amount.

Then, the buying and selling support / management server 4 sums up in order from the desired purchase amount of the higher purchaser, and determines the higher purchasers whose rank does not exceed the sales amount as the provisional purchaser (T15). -OK). Then, this fact is added to the temporary purchase decision file (T16). Regarding the fraction of sales volume, check the quantity sequentially from the purchase order of the next applicant,
If the desired quantity of purchase by the second-place applicant does not exceed a fraction, the purchaser is determined to be a temporary purchaser and added to the sales and temporary purchase determination file. Further, the desired purchase amount is subtracted from the fraction to obtain a new fraction. This operation is automatically executed for all buyers ranked in the purchase desire file. And when there are no more candidates (T1
7-OK), the tentative purchase decision file is transmitted to all buyer terminals 2 (T18, K8) and transmitted to seller terminal 1 (T18, S4).

The temporary purchase decision file created by the above procedure does not become a publicly authenticated temporary purchase contract as it is. Therefore, in an open network 5 environment,
Perform public authentication by the following procedure. After the final file is created, the temporary purchase decision file is automatically transmitted to the users described in the file using the network 5 (T18). At this time, the user number is not described, but a user code number that is applied only to the transaction is described.

The participants (sellers,
The purchaser) makes an intention to confirm using the network 5 (T19). Here, after receiving the indications of confirmation from all the entrants, the file is posted in a network environment accessible to all participants for a predetermined period of time in order to determine the provisional sales contract.

If there is an objection, an objection can be filed with the manager (administrator terminal 3) during the posting period (K9, S5). When the manager confirms that the objection is legitimate, the manager notifies the contents to all seller terminals 1 and buyer terminals 2 of the purchase provisional decision file from the manager terminal 3, and The temporary sale contract is invalidated (T20-NO).

If there is no objection during the posting period, the manager declares the conclusion of the provisional sales contract (T20-YE
S) The contact information of the buyer is sent to the seller, and the contact information of the seller is sent to the buyer together with the lot number by mail or fax (S5, K9). The seller terminal 1 or the buyer terminal 2 sends a confirmation of acceptance of this information via the network 5. Upon receiving this information, the administrator completes the support for the sale.

FIG. 13 is a flowchart showing the procedure of the purchase support process executed by the buyer terminal 2 and FIG. 14 is the purchase support process executed by the buyer terminal. 6 is a flowchart showing the procedure of FIG. As shown in these figures, when the buyer makes a purchase request first, the aforementioned seller terminal 1
The procedure on the side and the procedure on the side of the buyer terminal 2 are switched, so that the purchase and the sale are switched. The processing procedure of the trading support / management server 4 is basically the same as the description of FIGS.

If the purchaser desires a product or quantity to be purchased other than the lot number which can be purchased, the purchaser similarly inputs the user number and purpose to the network 5 using the purchaser terminal 2 ( K11). The purpose in this case is to select purchase outside the sales lot. Further, a security key file is input. When the trading support / management server 4 recognizes the buyer (T1), the participation of the buyer is permitted (T1-OK). Then, the purchaser is provided with a user code number and an input screen relating to the purchase through the network (T2).

This input screen is displayed on the buyer terminal 2 (K12). The purchaser can input desired purchase information (product name, purchase quantity, delivery place (seller's storage, purchaser's storage, etc.), purchase date, purchase price including transportation cost, payment method) (K13). . After entering these conditions,
The buyer terminal 2 transmits all inputs to the trading support / management server 4 using the network 5.

After confirming the receipt, the trading support / management server 4 automatically transmits the purchase reservation acceptance period and the lot number to the purchaser (T3). Further, the input of the purchase desire information to which the user code number of the buyer terminal 2 and the purchase reservation acceptance period and the lot number are added is converted into a file (purchase file), and the file number is associated with the lot number (T4).
Also, the seller terminal 1 is made to be able to access this purchase file on the network 5 (T5).

At this time, the seller similarly inputs the user number, purpose (sales outside the sales lot) and the security key file (S11), and obtains recognition and permission for participation from the manager. Upon permitting the participation (T5-OK), the trading support / management server 4 provides the seller with a list of user code numbers related to the trading, lot numbers currently receiving sales at that time, and respective product names ( Purchase request information)
Is provided to the seller terminal 1 through the network 5 (T6, T7).

The seller terminal 1 transmits a lot number whose detailed information is desired to be confirmed from the purchase desire information (S12) (S13). Thereby, the trading support / management server 4
In the file corresponding to the lot number, information (purchase file) necessary for making a sales decision is provided through the network 5 (T8, S14).

If there is a will to sell after confirming the contents, the seller inputs and displays the intention to sell and the lot number to be sold (S15). The trading support / management server 4 confirms the reception, and after the confirmation (T9), automatically provides an input screen to the seller using the network 5 (T10, S1).
6). Using this input screen, at seller terminal 1,
You can enter desired sales information (desired sales amount, transportation cost to delivery location). After inputting these conditions, all inputs are transmitted from the seller terminal 1 to the trading support / management server 4 using the network 5 (S17).

The trading support / management server 4 confirms the reception, and when it is confirmed that the sales are within the sales acceptance period (T11-O).
K), all information is added to the sales request file corresponding to the lot number (T12). The sales reception period is set in advance, and when the sales reception period ends (T13-
OK), the manager automatically classifies the files desired to be sold and ranks the sellers according to the priorities determined in advance and notified to both the seller and the buyer (T1).
4). The priorities are set in advance in consideration of the participant's wishes, for example, in the order of the higher selling price or the order of the desired sales amount.

Then, the trading support / management server 4 sums up in order from the desired sales volume of the high-ranking sales applicants, and determines the high-ranking sellers whose ranks do not exceed the purchase volume as the provisional sales determinator (T15). -OK). Then, the fact is added to the temporary sales decision file (T16). With respect to the fraction of the purchase quantity, the quantity is sequentially confirmed from the order of the desired sales, and if the desired quantity of sale does not exceed the fraction, the seller is set as the provisional sales decision-maker and added to the provisional sales decision file. Further, the desired sales amount is subtracted from the fraction to obtain a new fraction. This operation is automatically executed for all sellers ranked in the sales request file. Then, when there is no second-place applicant (T17-OK), the tentative sale file is transmitted to the seller terminal 1 (T18, S1).
8) and send it to buyer terminal 2 (T18, K
14).

The temporary purchase decision file and the temporary sale decision file created by the above-described procedure do not constitute a publicly authenticated temporary sale contract as it is. Therefore, in an open network environment represented by the Internet, public authentication is performed according to the following procedure. After the final file is created, the temporary sales decision file is automatically transmitted to the users described in the file using the network 5 (T1).
8). At this time, the user number is not described, but a user code number that is applied only to the transaction is described.

Participants who confirmed the file contents (purchasers,
The seller) uses the network 5 to display a confirmation will. After receiving the intention to confirm from all the entrants, the file is posted in a network environment accessible to all participants for a predetermined period in order to finalize the provisional sales contract.

If there is an objection, an objection can be filed with the administrator (administrator terminal 3) during the posting period (S19, K15). If the manager confirms that the objection is legitimate, the manager notifies the contents of the provisional sales decision file from the manager's terminal 3 to all entrants of the provisional sales decision file, and also notifies that the provisional sales contract is invalid. (T20-NO).

If there are no objections during the posting period,
The administrator declares the conclusion of the provisional sales contract (T20-YE
S). The contact information of the buyer is sent to the seller, and the contact information of the seller is sent to the buyer together with the lot number by mail or fax (K15, S19). The seller terminal 1 or the buyer terminal 2 sends a confirmation of acceptance of this information via the network 5. Upon receiving this information, the administrator completes the support for the sale.
