Description

  The present invention relates to a transaction management system and a transaction management method.

  Conventionally, in online transactions, etc., participants generally exchange information in an anonymous state to establish a transaction, but both sellers and buyers gain confidence in each other's partners. It is desirable to prepare the means.

  In general, in online transactions, there are many methods in which a buyer-side user performs a deposit process first, and a seller-side user confirms the deposit and ships the product. For this reason, since the seller side user can confirm payment, the necessity of confirming whether the buyer side user can trust is low. On the other hand, there is a risk that the user on the buyer side does not receive the product even when depositing. For this reason, it is necessary for the buyer-side user to trust the seller-side user in some way when depositing.

  For example, it is conceivable that a buyer side user refers to an evaluation value of an auction site or the like as a method for determining the reliability of a seller side user. Generally, the evaluation value on the seller side is held at an auction site or the like, and the buyer side can view the evaluation value. However, the evaluation value can be easily operated by “self-playing by multiple accounts”, “transfer of accounts when bad evaluation is attached”, or the like. Also, the evaluation value is generally a subjective numerical evaluation by a past transaction user and a comment by sentences, and it is determined that the buyer side is a malicious user such as browsing the evaluation value of the seller side and performing fraud To do so, some experience is required.

  As described above, it has been difficult for a buyer-side user to trust a seller-side user. For this reason, for example, the seller-side user has disclosed personal information such as an address and a name to the buyer-side user and conducts the transaction, thereby ensuring the trust of the seller-side user with respect to the buyer-side user.

  Here, an example of the flow of transactions on the auction site will be described with reference to FIG. For example, as illustrated in FIG. 12, first, the buyer-side user obtains the evaluation value of the seller-side user on the auction site and information on the item ((1) in FIG. 12), and then decides to purchase the item ( (2) of FIG.

  Then, after the seller side user receives a successful bid notification from the auction site or the like ((3) in FIG. 12), the seller side user discloses personal information such as address and name to the buyer side user ((4 in FIG. 12). )). Thereafter, the buyer side user deposits money to the seller side user ((5) of FIG. 12), and the seller side user sends the goods to the buyer side user ((6) of FIG. 12).

JP 2003-337897 A

  However, in the above prior art, the seller-side user discloses personal information such as an address and name to the buyer-side user, and thus the information on the seller-side user cannot be properly protected. There was a problem that the reliability of the side user could not be properly grasped.

  In order to solve the above-described problems and achieve the object, the transaction management system of the present invention uses an acquisition unit that acquires information on the behavior of a seller-side user in a transaction, and information acquired by the acquisition unit, A calculation unit that calculates reliability in the transaction of the seller-side user, and a storage unit that stores the reliability calculated by the calculation unit in a storage unit in association with identification information that uniquely identifies the seller-side user; It is provided with.

  In addition, the transaction management method of the present invention calculates the reliability in the transaction of the seller side user using the acquisition step of acquiring information related to the behavior of the seller side user in the transaction and the information acquired by the acquisition step. And a storage step of storing the reliability calculated by the calculation step in a storage unit in association with identification information for uniquely identifying the seller-side user.

  According to the present invention, there is an effect that the buyer-side user can make a transaction in a state where the reliability of the seller-side user is properly grasped while protecting the information of the seller-side user.

The transaction management system and the transaction management method according to the present application are not limited by this embodiment.

[First embodiment]
In the following embodiments, the configuration of the transaction management system according to the first embodiment, the configuration of the evaluation device, and the flow of processing of the evaluation device will be described in order, and finally the effects of the first embodiment will be described. .

[Configuration of transaction management system]
FIG. 1 is a diagram illustrating a configuration of a transaction management system including an evaluation device according to the first embodiment. A transaction management system 100 shown in FIG. 1 includes an evaluation device 10, a seller-side user terminal 20, a buyer-side user terminal 30, an auction site 40, and a collection device 50, which are connected via a network 60. Is done.

  The evaluation device 10 is a device that evaluates and manages the reliability of the seller with information (for example, a telephone number) that can uniquely identify the seller-side user. The evaluation device 10 acquires information on the behavior of the seller-side user from the collection device 50, calculates the reliability in the transaction of the seller-side user using the acquired information, and determines the calculated reliability for the seller-side user. The identification information is uniquely identified and stored in the storage unit.

  The seller-side user terminal 20 is a terminal owned by a seller-side user who sells products at an auction or the like. The buyer-side user terminal 30 is a terminal owned by a buyer-side user who purchases a product exhibited at an auction or the like. The seller-side user terminal 20 and the buyer-side user terminal 30 may be, for example, a mobile phone, a PHS (Personal Handyphone System), a PDA (Personal Digital Assistants), as well as a fixed terminal such as a personal computer (PC). Mobile terminals such as can also be adopted.

  The auction site 40 is a server device that manages the service of the auction site, and provides a web page related to an auction to the seller-side user terminal 20 and the buyer-side user terminal 30, for example.

  The collection device 50 collects information regarding the behavior of the seller side user. For example, the collection device 50 includes information regarding the contractor period, information regarding the storage status of charges, information regarding the call history, information regarding evaluation of the buyer user after the transaction, and information regarding the current address of the seller side user as information regarding the behavior of the seller side user. Collect any one or more of the information.

[Configuration of evaluation device]
Next, the configuration of the evaluation apparatus 10 shown in FIG. 1 will be described with reference to FIG. FIG. 2 is a block diagram showing a configuration of the evaluation apparatus 10 according to the first embodiment. As illustrated in FIG. 2, the evaluation device 10 includes a communication processing unit 11, a control unit 12, and a storage unit 13. The processing of each of these units will be described below.

  The communication processing unit 11 controls communication related to various information exchanged between the seller-side user terminal 20, the buyer-side user terminal 30, and the collection device 50 that are connected to be communicable with each other via the network 60. For example, the communication processing unit 11 uses the collection device 50 as information related to the seller-side user's behavior, information related to the contract period, information related to the charge storage status, information related to the call history, information related to evaluation of the buyer-side user after the transaction, And the information regarding the seller's user's present address is received.

  The storage unit 13 stores data and programs necessary for various processes performed by the control unit 12, and particularly includes a reliability storage unit 13a and a reliability definition information storage unit 13b that are closely related to the present invention. For example, the storage unit 13 is a semiconductor memory device such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk.

  The reliability storage unit 13a stores the reliability calculated by the calculation unit 12b described later. For example, as shown in FIG. 3, the reliability storage unit 13 a includes a “user ID” given to each user, “identification information” that can uniquely identify the seller-side user, and the seller-side user objectively in the transaction. The degree of good conduct, which is the degree of performance that can be expected in general, and the speed of negotiation, which the seller user can expect in the transaction, and the quality of the product that the seller user can expect from the transaction. The degree of “good quality” is stored in association with each other.

  Here, the “goodness degree”, “rapidity degree”, and “good quality degree” will be specifically described. A seller-side user who has a high degree of good conduct is more likely not to perform a fraudulent act such as “no payment yet” or “not shipping products”. In addition, the seller side user who has a high degree of speed is more likely to, for example, send out the merchandise faster and negotiate faster. In addition, a seller-side user who has a high quality level is more likely to expect a good quality when the quality of used electrical appliances varies.

  In the example of FIG. 3, the reliability storage unit 13 a stores a telephone number as identification information. Here, the “identification information” is information that can uniquely identify the seller-side user, may be disclosed by the seller, and may be information that is difficult for external operation, and is limited to a telephone number. It is not something.

  Specifically, as illustrated in FIG. 3, the reliability storage unit 13 a includes a user ID “1”, identification information “03-0000-xxxx”, and good deeds. The degree “3”, the speed “2”, and the quality “3” are stored in association with each other.

  The reliability definition information storage unit 13b stores reliability definition information that defines an index of an action that can be expected in a transaction in association with a value indicating the degree of reliability that the seller side user can expect in the transaction. As illustrated in FIG. 4, the reliability definition information storage unit 13b stores reliability definition information for each of the good conduct degree, the quickness degree, and the good quality degree.

  For example, the reliability definition information storage unit 13b stores the performance index “guaranteed with a transaction of 30,000 yen or less” that can be expected in the transaction in association with the value “3” of the seller's user regarding the good deed. To do. This means that if the value of the good conduct of the seller side user is “3”, it can be expected that the goods can be guaranteed if the transaction is 30,000 yen or less.

  In addition, for example, the reliability definition information storage unit 13b stores, for the swiftness, the action index that can be expected in the transaction “corresponding within 3 days” in association with the swiftness value “2” of the seller side user. . This means that when the value of the quickness of the seller side user is “2”, it can be expected that the processing related to the transaction will be handled within three days.

  Further, for example, the reliability definition information storage unit 13b stores an index of behavior “75% or more of non-defective product record” that can be expected in the transaction in association with the value “3” of the seller-side user's non-defective product level. . This means that when the value of the quality level of the seller side user is “3”, it can be expected that 75% or higher quality items will be exhibited.

  The control unit 12 has an internal memory for storing a program that defines various processing procedures and necessary data, and performs various processes using them, and particularly as closely related to the present invention, It has the acquisition part 12a, the calculation part 12b, the storage part 12c, and the determination part 12d.

  The acquisition unit 12a acquires information on the behavior of the seller-side user in the transaction from the collection device 50. Specifically, the acquisition unit 12a includes, as information on the seller's user behavior, information on the fixed telephone contract period, information on the telephone charge storage status, information on the call history, and information on the evaluation of the buyer user after the transaction. Any one or a plurality of pieces of information related to the current address of the seller-side user are acquired from the collection device 50. In addition, you may acquire directly the information regarding evaluation of the buyer side user after dealings from the buyer side user terminal 30 not via the collection apparatus 50. FIG.

  For example, the acquisition unit 12a may obtain information on whether or not there is a current unpaid status as a fixed telephone contract period, charge storage status, information indicating how many payment delays have occurred in the past three years, and calls during the daytime in the past three months. Information indicating the percentage of days with a history, information indicating whether the current address has been confirmed by installing a fixed telephone or optical fiber, and information indicating evaluation of buyer users after transactions in past transactions To get.

  The calculation unit 12b calculates the reliability of the seller side user's transaction using the information acquired by the acquisition unit 12a. Specifically, the calculation unit 12b uses the information acquired by the acquisition unit 12a to calculate a value indicating the degree of reliability that the seller side user can expect in the transaction.

  Moreover, the calculation part 12b is the degree of good conduct which is the degree of good deed that the seller side user can expect objectively in the transaction, and the degree of quick correspondence that the seller side user can expect in the transaction as the reliability in the transaction of the seller side user. One or a plurality of non-defective items, which are a certain degree of speed and the degree of quality of products that the seller side user can expect from the transaction, are calculated.

  Here, an example of reliability calculation processing will be described. For example, the calculation unit 12b sets the degree of good conduct to “+1” when the fixed telephone contract period acquired by the acquisition unit 12a is “1 year or more” and “3 years or more”. When the degree of good conduct is “+2” and “5 years or more”, the degree of good conduct is set to “+3”. In addition, the calculation unit 12b sets the good conduct degree to “−5” when there is a current unpaid state as the charge storage status, and sets the good conduct degree to “−1” when there are two or more payment delays in the past three years. When the payment delay is 3 times or more in the past 3 years, the good conduct degree is set to “−2”. Further, the calculation unit 12b sets the degree of good conduct to “+1” when the current address status is confirmed by fixed telephone or optical fiber installation. In this way, the sum of all values of good deeds is calculated and notified to the storage unit 12c.

  Further, for example, when the day when there is a daytime call history in the past three years is 60%, the calculation unit 12b calculates the speed as “3” and the daytime call history in the past three years is calculated. When a certain day is 30%, the speed is calculated as “2” and notified to the storage unit 12c. Note that the speed is 4 or 5 only for the seller-side user who is a business line builder and is authorized by the application. In addition, as information indicating the evaluation of the buyer user after the transaction in the past transaction, the calculation unit 12b sets the non-defective product level to “5” if the non-defective product record is 95% or more, and the non-defective product record is 90% or more. For example, if the quality level is “4” and the quality record is 75% or higher, the quality level is “3”. If the quality level is 50% or higher, the quality level is “2” and the quality level is 50. If it is less than%, the quality is calculated as “1”.

  The storage unit 12c stores the reliability calculated by the calculation unit 12b in the reliability storage unit 13a in association with identification information that uniquely identifies the seller-side user. Specifically, the storage unit 12c associates the telephone number of the seller-side user with the values of “goodness degree”, “rapidity degree”, and “goodness degree” calculated by the calculation unit 12b, and the reliability storage unit Store in 13a.

  The determination unit 12d obtains an action index that can be expected in the transaction according to the value calculated by the calculation unit 12b, and determines whether the action index satisfies the condition of the transaction desired by the seller or the buyer. . Specifically, when the determination unit 12d receives a request for determining the reliability of a transaction including identification information and transaction conditions, the behavior indicator corresponding to the identification information indicates a transaction desired by the seller or the buyer. It is determined whether or not the above condition is satisfied, and the determination result is transmitted to the request source.

  Here, the processing of the determination unit 12d will be specifically described with reference to the examples of FIGS. FIG. 5 is a diagram for explaining processing for requesting the seller's own reliability. FIG. 6 is a diagram illustrating a process in which the buyer side requests the reliability of the transaction. In the example of FIG. 5, the seller-side user designates the amount of sale “20,000 yen” as a transaction condition together with the seller-side user's telephone number, and the seller-side user's good conduct degree is “3”. The case where the quality level is “3” will be described as an example.

  In this case, the determination unit 12d refers to the reliability definition information, and acquires the index “guaranteeed for transactions of 30,000 yen or less” corresponding to the good conduct degree “3”. In other words, as the reliability of the seller-side user can be expected to be guaranteed with a transaction of “30,000 yen” or less, the determination result is “guaranteed” for the sale in the transaction, which is higher than the price of “20,000 yen” for sale. Is transmitted to the seller side user terminal 20 as the reliability of the seller side itself. Further, the determination unit 12d refers to the reliability definition information, and transmits a determination result of “75% or higher non-defective product record” corresponding to the non-defective product level “3” to the seller-side user terminal 20 as the seller's own reliability. To do.

  In the example of FIG. 6, the seller side user specifies the amount of sale “20,000 yen” and the requested speed “within 1 day” as the transaction condition together with the seller side user telephone number. The case where the seller's user's good conduct is “3”, the quickness is “2”, and the good quality is “3” will be described as an example.

  In this case, the determination unit 12d refers to the reliability definition information, and acquires the index “guaranteed for transactions of 30,000 yen or less” corresponding to the good conduct degree “3”. And since it can be expected to guarantee with transactions of “30,000 yen” or less and is higher than the price of “20,000 yen” for sale, the judgment result of “guaranteeable” for the sale in the transaction is given as the reliability of the transaction. It transmits to the buyer side user terminal 30. Further, the determination unit 12d refers to the reliability definition information, and acquires the index “corresponding within 3 days” corresponding to the speediness “2”. Since the response time is longer than “within 1 day”, and only the response within “3 days” is required, the determination result that “response is not possible” for the speed required by the buyer is used as the reliability of the transaction. To the user terminal 30 on the side. Further, the determination unit 12d refers to the reliability definition information, and transmits a determination result of “non-defective product record 75% or more” corresponding to the non-defective product level “3” to the buyer-side user terminal 30 as the reliability of the transaction.

  Here, the outline of the transaction management process in the transaction management system 100 will be described with reference to FIG. FIG. 7 is a diagram illustrating an outline of transaction management processing in the transaction management system. In the evaluation apparatus 10 according to the first embodiment, as shown in FIG. 7, an action history such as a call is acquired from the collection apparatus 50 together with personal information such as an address and a name of the seller side user. Then, the evaluation device 10 calculates the seller's reliability, determines the reliability of the transaction, and transmits the reliability of the transaction to the buyer-side user terminal 30.

  Then, the buyer-side user considers whether or not to conduct a transaction with the seller-side user with reference to the reliability of the transaction, and when performing the transaction, the auction site 40 is used to perform the same transaction as usual. I do. In this way, it is possible to provide transaction reliability based on information obtained from data that is difficult to operate externally attached to the telephone number without disclosing personal information such as the address and name of the seller user. It is. In addition, the data presented to the buyer-side user is anonymized information during the calculation process. Instead of providing the seller's user's direct reliability and personal information, the transaction reliability is given to the buyer-side user. It is possible to present and protect the personal information of the seller side user.

[Example of processing of evaluation device]
Next, the process of the evaluation apparatus 10 is demonstrated using FIGS. FIG. 8 is a sequence diagram showing the flow of seller side user reliability calculation processing in the transaction management system according to the first embodiment. FIG. 9 is a sequence diagram showing the flow of seller-side user reliability confirmation processing in the transaction management system according to the first embodiment. FIG. 10 is a sequence diagram illustrating a flow of transaction reliability determination processing in the transaction management system according to the first embodiment.

  First, the flow of the seller side user reliability calculation process in the transaction management system 100 according to the first embodiment will be described with reference to FIG. As shown in FIG. 8, the collection device 50 collects behaviors such as calls and past transaction results from the seller-side user terminal 20 or the like (steps S101 and S102). Then, the collection device 50 accumulates information about the collected seller (step S103).

  And the acquisition part 12a of the evaluation apparatus 10 acquires the information regarding a seller from the collection apparatus 50 (step S104), and notifies the information regarding the acquired seller to the calculation part 12b (step S105). Using the information acquired by the acquisition unit 12a, the calculation unit 12b calculates the reliability of the seller user transaction (step S106) and notifies the storage unit 12c (step S107). Then, the storage unit 12c stores the reliability calculated by the calculation unit 12b in the reliability storage unit 13a in association with identification information that uniquely identifies the seller-side user (step S108).

  Next, the flow of the seller side user reliability confirmation process in the transaction management system 100 according to the first embodiment will be described with reference to FIG. As shown in FIG. 9, the seller-side user terminal 20 requests the evaluation apparatus 10 for its reliability (step S201). Here, when the seller-side user terminal 20 requests its own reliability, the seller-side user terminal 20 notifies the evaluation device 10 of the transaction conditions together with the seller-side user's own telephone number.

  The determination unit 12d of the evaluation device 10 performs transaction reliability determination processing (step S202). Specifically, when the determination unit 12d receives a request for determining the reliability of a transaction including identification information and transaction conditions, the action index corresponding to the identification information indicates the transaction conditions desired by the seller. It is determined whether or not it is satisfied. Then, the determination unit 12d returns the determination result to the seller-side user terminal 20 as the seller's own reliability (step S203).

  Thereafter, the seller user of the seller-side user terminal 20 selects an item for sale, bids, etc. with reference to the seller's own reliability (step S204) and places it on the auction site 40 (step S205).

  Next, the flow of transaction reliability determination processing in the transaction management system 100 according to the first embodiment will be described with reference to FIG. As shown in FIG. 10, after a sale negotiation with a seller or a tentative agreement is made at the auction site 40 (step S301), the buyer-side user terminal 30 requests the determination unit 12d for the reliability of the transaction ( Step S302). Then, the determination unit 12d requests the reliability storage unit 13a to request the seller's reliability using the seller's identifier as a key (step S303).

  Here, the evaluation apparatus 10 transmits a request for permission for transmission of reliability to the seller-side user terminal 20 (step S304). When the evaluation device 10 receives permission from the seller-side user terminal 20 (step S305), the determination unit 12d determines the seller's trust. The degree is acquired from the reliability storage unit 13a (step S306). Note that the process of requesting permission from the seller-side user terminal 20 may be omitted.

  Then, the determination unit 12d performs transaction reliability determination processing (step S307). Then, the determination unit 12d returns the determination result to the buyer side user terminal 30 as the reliability of the transaction (step S308).

  Thereafter, at the auction site 40, after the seller and the buyer negotiate the sale negotiation (step S309), the transaction is performed (step S310). And the evaluation apparatus 10 will request the buyer side user terminal 30 for the transaction evaluation request | requirement, if the shipping notification is received from the seller side user terminal 20 (step S311) (step S312). Then, the evaluation device 10 acquires the evaluation after the transaction from the buyer-side user terminal 30 (Step S313), and updates the “good quality” in the seller's reliability in the reliability storage unit 13a (Step S314).

[Effect of the first embodiment]
As described above, the evaluation device 10 of the transaction management system 100 according to the first embodiment acquires information on the behavior of the seller-side user in the transaction, and uses the acquired information to determine the reliability in the transaction of the seller-side user. And the calculated reliability is stored in the reliability storage unit 13a in association with identification information for uniquely identifying the seller-side user.

  As a result, in the transaction management system 100 according to the first embodiment, the buyer-side user can conduct a transaction in a state in which the seller-side user's reliability is properly grasped while protecting the seller-side user's information. is there. In other words, it is possible to provide the reliability of transactions based on information obtained from data that is difficult to operate externally attached to a telephone number etc. without disclosing personal information such as the address and name of the seller side user. is there.
