In terms of the management device 130, a company has the characteristics of an affiliated store, so in this embodiment and the following embodiments and claims, such company is referred to as an affiliated store.

The communication network 150 refers to a connection structure that allows information exchange between communication nodes. An example of such a communication network 150 includes a local area network (LAN), a wide area network; Wired networks such as WAN or Value Added Network (VAN), mobile radio communication network, satellite communication network, Bluetooth, Wibro (Wireless Broadband Internet), and HSDPA (High Speed Downlink Packet Access) It can be implemented as any type of wireless network, such as, or a combination thereof.

The customer terminal 110 is a user device owned by a customer registered with an affiliated store, such as a credit card company, bank, or insurance company. The customer terminal 110 is a mobile terminal that includes personal communication system (PCS), global system for mobile communications (GSM), personal digital cellular (PDC), personal handyphone system (PHS), personal digital assistant (PDA), and international system (IMT). All types of handheld-based wireless communication devices such as Mobile Telecommunication (Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), Wibro (Wireless Broadband Internet) terminal, etc. It may include a fixed communication device such as a desktop or laptop.

The customer accesses the affiliated store device 120 through the customer terminal 110 and agrees to the terms and conditions regarding the anti-spam service according to the present invention with the affiliated store. These terms and conditions include consent regarding the use of the customer’s personal information. In other words, since the affiliated store must transmit the customer's phone number and the customer's unique information (e.g., date of birth, resident registration number, address, etc.) to the telecommunication company to check whether the customer's phone number has changed, the affiliated store must provide consent to the use of such personal information. Received from customer. The customer terminal 110 can use a web browser or a dedicated application distributed by an affiliated store to agree to the terms and conditions through identity authentication through a joint certificate, etc.

The affiliated store device 120 is a communication device owned by companies such as credit card companies, banks, and insurance companies. The affiliated store device 120 may be a server, a general personal computer or POS system, or a mobile terminal. In this embodiment, only large companies such as credit card companies, banks, and insurance companies are used as examples of affiliated stores, but this is not limited, and small business owners who have customer phone numbers may also be included as one of the affiliated stores.

The affiliated store device 120 stores and manages customer personal information. Customer information includes phone number, name, address, date of birth or resident registration number, gender, etc. The affiliated store device 120 transmits a phone number change confirmation request including affiliated store identification information, customer phone number, and customer unique information to the management device 130, and receives the customer's phone number change confirmation result from the management device 130. Receive. Here, customer-specific information is information that can uniquely identify the customer, such as date of birth, resident registration number, or address, other than phone number. The affiliated store device 120 may use a dedicated application for the present invention, or may use a general Internet browser, etc.

The affiliated store device 120 can check whether the phone number has changed at certain intervals. For example, you can check whether your phone number has changed once every six months or once a year. The affiliated store device 120 can check whether the phone number has changed for each individual customer at a predetermined period, or can check whether the phone number has changed for all customers once at a predetermined period. The affiliated store device 120 is set not to send calls or messages to customers whose phone numbers have changed. Preferably, the affiliated store device 120 can manage to prevent calls or messages from being sent by setting a phone number change flag in the customer's personal information.

When the management device 130 receives a phone number change confirmation request including affiliated store identification information, customer phone number, and customer unique information from the affiliated store device 120, the management device 130 generates an identification code corresponding to the affiliated store identification information, the customer phone number, and the customer. A phone number change confirmation request containing unique information is transmitted to the telecommunication company server 140. At this time, the management device 130 may store and manage a relationship table between affiliated store identification information and identification codes corresponding to the affiliated store identification information. By inserting the corresponding identification code instead of the affiliated store identification information in the phone number change confirmation request transmitted to the telecommunication company server 140, the telecommunication company can prevent the telecommunication company from knowing the affiliated store to which the customer has signed up. If the affiliated store identification information is information promised between the affiliated store device 120 and the management device 130 and is unrecognizable information from the telecommunication company, the management device 130 includes the affiliated store identification information in the phone number change confirmation request and sends it to the telecommunication company server. It can be sent to (140).

When the management device 130 receives the phone number change confirmation result from the telecommunication company server 140, it transmits the phone number change confirmation result to the corresponding affiliated store device 120. The phone number change confirmation result received from the telecommunication company server 140 includes an identification code corresponding to the affiliated store identification information and information on whether the phone number of each customer has been changed. The management device 130 determines to which affiliated store device 120 the phone number change confirmation result should be transmitted based on the identification code included in the phone number change confirmation result received from the telecommunication company server 140, and sends the phone number change confirmation result to the corresponding affiliated store. The phone number change confirmation result is transmitted to the device 120.

If there are multiple telecommunication companies, the management device 130 may transmit the same phone number change confirmation request to each telecommunication company server 140 and receive a phone number change confirmation result from each telecommunication company server 140. The management device 130 may simultaneously transmit a phone number change confirmation request to each telecommunication company server 140, or sequentially transmit a phone number change confirmation request to each telecommunication company server 140. The management device 130 compiles the phone number change confirmation results received from each telecommunication company server 140 and transmits the phone number change confirmation results to the affiliated store device 120 . The phone number change confirmation result includes either whether the phone number has been changed, whether the phone number has been changed, or whether it cannot be confirmed for each customer.

In one embodiment, the management device 130 sequentially transmits a phone number change confirmation request to a plurality of telecommunication company servers 140 for a specific affiliated store, and the phone number received from the previously ordered telecommunication company server 140 Only for customers who cannot confirm whether their phone number has been changed in the change confirmation result, a phone number change confirmation request can be sent to the telecommunication company server 140 in the next order. For example, if the first customer is subscribed to the second telecommunication company and the second customer is registered to the first telecommunication company, the first telecommunication company has only the second customer's information and does not have the first customer's information, so the second customer You can check whether the phone number has changed only for the customer. Therefore, after receiving the phone number change confirmation results for the first and second customers from the first telecommunication company, the management device 130 requests the second telecommunication company to confirm the phone number change for only the first customer, excluding the second customer.

The telecommunication company server 140 is a device operated by the telecommunication company and stores and manages the personal information of customers subscribed to the telecommunication company. Customer personal information includes phone number, name, address, date of birth or resident registration number, gender, etc. When receiving a phone number change confirmation request including the customer phone number and customer unique information from the management device 130, the telecommunication company server 140 compares the customer phone number and customer unique information with the personal information of telecommunication company customers to obtain a phone number. The change is checked and the phone number change confirmation result is transmitted to the management device 130.

Preferably, the telecommunication company server 140 searches for its customer's phone number that matches each customer's unique information (e.g., date of birth or resident registration number) included in the phone number change confirmation request, and confirms the searched customer's phone number and phone number change. Compare each customer phone number included in the request to see if they match. If there is a match, the phone number is not changed. If there is a mismatch, the phone number is changed. If there is no customer with matching customer-specific information (e.g. date of birth or resident registration number), it is judged as unverifiable. The telecommunication company server 140 includes one of the presence, absence, or unconfirmation of a phone number change for each customer in the phone number change confirmation result.

In one embodiment, the affiliated store device 120, the management device 130, and the telecommunication company server 140 may encrypt and transmit data when transmitting and receiving data with the other party. To this end, the affiliated store device 120 and the management device 130 may share the same encryption/decryption key, and the management device 130 and the telecommunication company server 140 may share the same encryption/decryption key.

Figure 2 is a flowchart explaining a method for preventing spam due to phone number change according to an embodiment of the present invention.

Referring to FIG. 2, in step S201, an affiliated store such as a credit card company, bank, or insurance company agrees to the terms and conditions regarding the anti-spam service according to the present invention with a customer registered with the affiliated store. These terms and conditions include consent regarding the use of the customer’s personal information. The customer terminal 110 can access the affiliated store device 120 using a web browser or a dedicated application distributed by the affiliated store to agree to the terms and conditions.

In step S202, the affiliated store device 120 transmits a phone number change confirmation request including affiliated store identification information, a customer phone number, and date of birth as customer unique information to the management device 130.

In steps S203 and S204, the management device 130 transmits a phone number change confirmation request to the plurality of communication service provider servers 140. In this embodiment, the management device 130 may transmit a phone number change confirmation request to a plurality of communication service provider servers 140 simultaneously or sequentially. In this embodiment, sequential transmission from telecommunication company server #1 to telecommunication company server #N is explained. At this time, the management device 130 changes the affiliated store identification information to the corresponding identification code and transmits a phone number change confirmation request, thereby preventing the communication company from knowing which affiliated store the customer information is.

In steps S205 and S206, each telecommunication company server 140 checks whether the phone number has been changed by comparing the customer phone number and date of birth included in the phone number change confirmation request with the information of the telecommunication company customers. Specifically, the telecommunication company server 140 searches for its customer phone number that matches the date of birth of each customer included in the phone number change confirmation request, and searches for its customer phone number and each customer phone number included in the phone number change confirmation request. Compare the numbers to see if they match. If there is a match, the phone number is not changed. If there is a mismatch, the phone number is changed. If there are no customers with the same date of birth, it is judged as unverifiable.

In steps S207 and S208, the telecommunication company server 140 manages a phone number change confirmation result including an identification code corresponding to the affiliated store identification information and one of presence, absence, or unconfirmation of a phone number change for each customer. Transmitted to device 130.

In step S209, the management device 130 compiles the phone number change confirmation results received from all of the plurality of communication service provider servers 140 and transmits the phone number change confirmation results to the affiliated store device 120. At this time, the management device 130 verifies the affiliated store by searching the relationship table for affiliated store identification information that matches the identification code included in the phone number change confirmation result. The management device 130 transmits to the affiliated store device 120 a phone number change confirmation result indicating whether or not the phone number for each customer has been changed or not being confirmed.

In the embodiment referring to Figure 2, the date of birth is used as an example of the customer's unique information, but is not limited thereto, and personal information that can uniquely identify the customer, such as a resident registration number or address, may be used.

In the above embodiment, the affiliated store device 120 can check whether the phone number has changed at regular intervals. For example, you can check whether your phone number has changed once every six months or once a year. The affiliated store device 120 can check whether the phone number has changed for each individual customer at a predetermined period, or can check whether the phone number has changed for all customers once at a predetermined period. The affiliated store device 120 is set not to send calls or messages to customers whose phone numbers have changed. Preferably, the affiliated store device 120 can manage to prevent calls or messages from being sent by setting a phone number change flag in the customer's personal information.

In the above embodiment, the management device 130 transmits the same phone number change confirmation request to all telecommunication company servers 140. In another embodiment, the management device 130 sequentially transmits a phone number change confirmation request to each telecommunication company server 140 for a specific affiliated store, and changes the phone number received from the telecommunication company server 140 in the previous order. Only for customers whose phone number cannot be confirmed as a result of the confirmation, a phone number change confirmation request is sent to the telecommunication company server 140 in the next order.

For example, if the first and second customers have their phone numbers and dates of birth stored in the telecommunication company server #1, and the third customer has their phone numbers and dates of birth stored in the telecommunication company server #2, the management device 130: A phone number change confirmation request containing the phone numbers and dates of birth of the first to third customers is sent to the telecommunication company server #1, and a phone number change request is sent from the telecommunication company server #1 for the first and second customers, and for the third customer. If you receive a phone number change confirmation result that cannot be confirmed, in the next step, a phone number change confirmation request is sent to telecommunication company server #2, excluding the first and second customer information, but including only the third customer's phone number and date of birth. Receive the confirmation result of the third-party customer's phone number change.

According to the above embodiment, the affiliated store device 120 may transmit personal information (e.g., phone number and customer unique information) of all customers at once to the telecommunication company server 140, and in this case, the telecommunication company may transmit the personal information of all customers of each affiliated store. There is a risk of having information. Therefore, there is a need to ensure that telecommunications companies cannot know which affiliated store a customer's personal information belongs to. As described below, each affiliated store device 120 does not transmit all customer personal information to the management device 130 at once, but divides all customer personal information into a predetermined number of unit data and transmits them. For example, each unit of data may consist of a pair of customer phone numbers and customer unique information for 100 customers. In addition, the management device 130 aggregates the unit data received from all affiliated store devices 120 whenever the number reaches a predetermined number (eg, 10) and transmits it to the telecommunication company server 140.

Figure 3 is a flowchart illustrating a method of splitting and transmitting customer personal information according to an embodiment of the present invention.

Referring to FIG. 3, in steps S301 and S302, each of the plurality of affiliated store devices 120 divides the entire customer personal information (eg, phone number and customer unique information) of each affiliated store into a predetermined number of unit data. For example, if affiliated store device #1 holds the personal information of 25 million customers, the customer personal information is divided into units of 1,000 people. Therefore, information on 25 million customers is divided into 25,000 units of data of 1,000 each.

In steps S303 and S304, each affiliated store device 120 sequentially transmits a phone number change confirmation request to the management device 130 for each unit of data at regular intervals. For example, each affiliated store device 120 first transmits a phone number change confirmation request including first unit data and affiliated store identification information, and after a certain period of time, changes the phone number including second unit data and affiliated store identification information. As a method of transmitting confirmation requests, phone number change confirmation requests are sequentially transmitted at regular intervals.

In step S305, the management device 130 determines whether a predetermined number of unit data received from a plurality of affiliated store devices 120 (for example, 10 in this embodiment) have been received in chronological order. For example, when 10 units of data are received, in step S306, the management device 130 transmits a phone number change confirmation request including the 10 units of data to the telecommunication company server 140. At this time, the management device 130 may add and transmit an identification code that can identify the affiliated store, the meaning of which is unknown to the telecommunication company, to each unit of data.

In step S307, the telecommunication company server 140 determines whether the phone number has been changed by comparing each customer's phone number and customer unique information (e.g., date of birth) in the 10 unit data included in the phone number change confirmation request with the information of the telecommunication company customers. Confirm. Specifically, the telecommunications company server 140 searches for its customer phone number that matches the customer-specific information (e.g., date of birth) of each customer included in the phone number change confirmation request, and confirms the searched customer phone number and phone number change. Compare each customer phone number included in the request to see if they match. If there is a match, the phone number is not changed. If there is a mismatch, the phone number is changed. If there are no customers with the same date of birth, it is judged as unverifiable.

In step S308, the telecommunication company server 140, for each of the 10 units of data, reports a phone number change confirmation result including one of presence, absence, or unconfirmation of a phone number change for each customer within each unit data to the management device 130. ) and send it to

In this embodiment, one telecommunication company server 140 is shown, but as described with reference to FIG. 2, it is possible to check whether the phone number has been changed using a plurality of telecommunication company servers 140. Since this has been explained with reference to FIG. 2, detailed description will be omitted here.

In step S309, the management device 130 checks the unit data of each affiliated store based on the identification code in the phone number change confirmation result received from the telecommunication company server 140, and sends the corresponding unit data to each affiliated store device 120. Send a phone number change confirmation result containing . That is, the management device 130 transmits a phone number change confirmation result indicating whether or not the phone number has been changed for each customer, or whether confirmation is not possible, to the corresponding affiliated store device 120.

Steps S306 to S310 described above are repeated in units of, for example, 10 data units. That is, when the unit data received from the plurality of affiliated store devices 120 reaches 10, the management device 130 compiles the unit data, requests phone number change confirmation from the telecommunication company server 140, and converts the confirmation result into 10 unit data. A reply is sent to the affiliated store device(s) 120 that transmitted the message. Therefore, the telecommunication company server 140 cannot know which affiliated store the customer's personal information belongs to.

According to the embodiment referring to FIG. 3, the telecommunication company cannot know which affiliated store the customer's personal information belongs to, but the communication path between the affiliated store device 120 and the management device 130 or the management device 130 and the telecommunication company server 140 ) Customer personal information may be leaked by hacking between communication paths. Therefore, there is a need to ensure that individuals cannot be identified when personal information is leaked through hacking on the communication path. As explained below, the customer's phone number and the customer's unique information required to check whether the phone number has been changed are transmitted and received separately, preventing individuals from being identified in the event of personal information leakage due to hacking on the communication path.

Figure 4 is a flowchart illustrating a method of separately transmitting and receiving phone numbers and customer unique information according to an embodiment of the present invention.

Referring to FIG. 4, the management device 130 and the telecommunication company server 140 separately receive the customer's phone number and customer's unique information (e.g., date of birth, address, resident registration number, etc.), which is customer personal information to confirm the change of phone number. For this reason, servers or ports (131, 141) for sending and receiving phone numbers and servers or ports (132, 142) for sending and receiving customer unique information are operated separately. When separating a server, the server can be identified by the server IP address, and when separating a port, the port can be identified by the port number. In this embodiment, separate operation of ports is explained.

Each of the plurality of affiliated store devices 120 separates the customer phone number and customer unique information (e.g., date of birth, address, resident registration number, etc.), which are customer personal information to confirm the change of phone number, and transmits them to the management device 130.

For example, in step S401, affiliated store device #1 transmits a phone number change confirmation request including affiliated store identification information and customers' phone numbers to the first port 131 of the management device 130, and in step S402, A phone number change confirmation request including the affiliated store identification information and the customer's unique information (e.g., date of birth) is transmitted to the second port 132 of the management device 130.

Similarly, in step S403, affiliated store device #N transmits a phone number change confirmation request including affiliated store identification information and customers' phone numbers to the first port 131 of the management device 130, and in step S404, affiliated store identification A phone number change confirmation request including customer information and customer-specific information (e.g., date of birth) is transmitted to the second port 132 of the management device 130.

In one embodiment, each affiliated store device 120 divides the phone numbers of all customers into a predetermined number of unit data, as described with reference to FIG. 3, and also divides the customer-specific information of all customers into a predetermined number of unit data. After dividing, each unit of data can be transmitted to the management device 130. That is, unit data about customer phone numbers is transmitted to the first port 131 of the management device 130, and unit data about customer unique information is transmitted to the second port 132 of the management device 130. You can.

In step S405, the management device 130 compiles the customer phone numbers received from each affiliated store device 120 in steps S401 and S403 and sends a phone number change confirmation request including these to the first terminal of the telecommunication company server 140. Send to port (141). And in step S406, the management device 130 compiles the unique information of customers received from each affiliated store device 120 in steps S402 and S404 and sends a phone number change confirmation request including this to the telecommunication company server 140. Transmit to port 2 (142).

In one embodiment, as described with reference to FIG. 3, the management device 130 aggregates the unit data received separately from each affiliated store device 120 when the number reaches a predetermined number, for example, 10. You can request confirmation of phone number change from the telecommunication company server 140. That is, when the management device 130 receives 10 pieces of unit data about customer phone numbers, it aggregates them and transmits them to the first port 141 of the telecommunication company server 140, and unit data about customer unique information. When 10 are received, they can be aggregated and transmitted to the second port 142 of the telecommunication company server 140.

In the embodiment referring to FIG. 4, the telecommunication company server 140 receives the customer's customer phone number and the customer's unique information, such as date of birth, separately. Therefore, in order to check whether the phone number has changed, the separately received customer phone number is received. You must match the number and date of birth. In other words, you must be able to find the date of birth corresponding to each customer phone number. To this end, the affiliated store device 120 inserts matching information into the header and body of the phone number change request and transmits it. Specifically, it is as follows:

First, when the first phone number change request including the customer phone number and the second phone number change request including the date of birth each include the customer phone number and date of birth of the same customer, each header ( header), the same master number and file order information are recorded. Accordingly, the management device 120 and the telecommunication company server 140 recognize the first phone number change request and the second phone number change request with the same master number and file sequence number as one set.

And the customer's phone numbers and date of birth are recorded in the body of each set of the first phone number change request and the second phone number change request. At this time, the same transaction code is matched and recorded with the customer phone number and date of birth of the same customer. Therefore, it can be seen that the customer phone number and date of birth with the same transaction code in each body of the first phone number change request and the second phone number change request, which are one set, are personal information of the same customer.

An example of the header and body of a phone number change request including date of birth is as follows.

#header

#file_mst_no, file_seq

2021110301, 1

#body

#trns_no, birthday[8](encrpyt), gender

2021110300001, 19770801, 1

2021110300002, 19770802, 2

An example of the header and body of a phone number change request containing the customer's phone number is as follows.

#header

#file_mst_no, file_seq

2021110301, 1

#body

#trns_no,crer_cd, mobl_no(encrypt)

2021110300001, 01097272968

2021110300002, 01097272969

Looking at the two examples above, the master number (file_mst_no) '2021110301' in the header and the file order information (file_seq) '1' are the same, and the transaction code '2021110300001' of the date of birth (birthday) '19770801' in the body is the customer phone number '2021110300001'. It is the same as the transaction code of '01097272968', and the transaction code '2021110300002' of the birthday '19770802' in the body is the same as the transaction code of the customer phone number '01097272969'.

The telecommunication company server 140 compares the headers of the phone number change requests received through the first port 141 and the headers of the phone number change requests received through the second port 142 to create a set of phone numbers. Change requests are checked, and a pair of the same customer's customer phone number and date of birth is extracted from the phone number change requests in one set based on the transaction code to check whether the phone number has been changed.

After checking whether the phone number has been changed, the telecommunication company server 140 transmits the phone number change confirmation result including the customer phone number to the management device 130 through the first port 141 and the second port 142. The phone number change confirmation result including the date of birth is transmitted to the management device 130. At this time, the telecommunication company server 140 sets the format of the phone number change confirmation result to be the same as the format of the phone number change confirmation request. In other words, the master number and file order information in the header, and the transaction code in the body are the same. Additionally, the telecommunication company server 140 inserts the phone number change confirmation result into at least one of a phone number change confirmation result including the customer's phone number and a phone number change confirmation result including the date of birth.

The management device 130 transmits the phone number change confirmation result received from the first port 141 of the telecommunication company server 140 to the affiliated store device 120 through its first port 131, and the telecommunication company server ( The phone number change confirmation result received from the second port 142 of 140 is transmitted to the affiliated store device 120 through its second port 132.
