Identification information of the member terminals (151, 152, 153) Member information 1 Identification 1 Member information 2 Identification 2 Member information 3 Identification 3 ... ...

The group purchase listing information posting unit 112 receives, from the electronic terminal 170 of the home care service provider 160, product description information about the first home care service product to be provided by the home care service provider 160, the first 1 Information on the group purchase solicitation deadline for 1 home care service product and a price table for the first home care service product (in the price table, a plurality of different prices for the first home care service product, each When group purchase property information consisting of a range value of the number of target number of people designated to correspond to the price is recorded), posting information requesting that the group purchase property information be posted on the web page for group purchase When the request is received, the group purchase listing information is posted on the group purchase web page.

Here, the web page for group purchase refers to a web page that is pre-built so that a plurality of members 141, 142, and 143 can participate in group purchase of home care service products.

The group purchase price determination unit 113 is configured to post the group purchase listing information on the web page for group purchase by the group purchase listing information posting unit 112. When the group purchase solicitation deadline has elapsed, a plurality of members After checking the number of first members participating in the group purchase of the first home care service product among the ones 141, 142, and 143, referring to the price table, among the plurality of prices, the A first price corresponding to a range value of the target number of group purchases to which the number of people belongs is determined as the group purchase price for the first home care service product.

When the first price is determined as the group purchase price for the first home care service product by the group purchase price determining unit 113 , the inquiry message transmission unit 114 receives the first price from the member information storage unit 111 . Checking the identification information of each member terminal of each member, while transmitting the information on the first price to each member terminal of the first members, querying the final payment intention for the first home care service product Send a query message.

Hereinafter, operations of the group purchase listing information posting unit 112 , the group purchase price determining unit 113 , and the query message transmitting unit 114 will be described in detail, for example.

First, from the electronic terminal 170 of the home care service provider 160 to the collective purchase platform service server 110, product description information about 'home care service product 1' that the home care service provider 160 is going to provide; As information on the group purchase solicitation deadline for 'home care service product 1' and group purchase listing information consisting of a price table for 'home care service product 1' is received, the group purchase listing information is displayed on the web page for group purchase Assume that a request to publish information is received requesting that it be posted to .

In this case, it is assumed that the group purchase recruitment deadline for 'home care service product 1' is 'August 20, 2021,' and the price table for 'home care service product 1' is as shown in Table 2 below.

About 'Home Care Service Product 1'
Multiple different prices (won) Range value of the group purchase target number of people 100,000 less than 15 70,000 15 or more but less than 30 50,000 30 or more

Then, the group purchase listing information posting unit 112 may publish the group purchase listing information on the web page for group purchase.

Through this, the plurality of members 141, 142, and 143 can participate in the group purchase of 'home care service product 1' by checking the group purchase information posted on the group purchase web page. .

In this way, after the group purchase listing information is posted on the web page for group purchase by the group purchase listing information posting unit 112, the deadline for group purchase recruitment for 'home care service product 1' is August, 2021. When it is said that '20 days' has elapsed, the group purchase price determination unit 113 checks the number of first members who participated in the group purchase for 'home care service product 1' among the plurality of members 141 , 142 , 143 . can

As a result, when it is confirmed that the number of first members participating in the group purchase for 'home care service product 1' among the plurality of members 141, 142, and 143 is '20', the group purchase price determination unit (113) refers to the price table as shown in Table 2, and among the plurality of prices, a first price corresponding to a range value of the target number of group purchases to which '20 people', which is the number of the first members, belong, It can be confirmed as a group purchase price for 'Home Care Service Product 1'.

In relation to this, in the price table as shown in Table 2, the range value of the target number of group purchases to which '20 people' belongs is '15 or more and less than 30', and '15 or more and less than 30' among the plurality of prices. Since the price corresponding to '70,000 (won)', the group purchase price determination unit 113 may determine '70,000 (won)' as the group purchase price for 'home care service product 1'.

Then, the query message transmitting unit 114 checks the identification information of the member terminals of each of the first members of the '20 people' from the member information storage unit 111 as shown in Table 1 above, While transmitting information on '70,000 (KRW)' to each member terminal of the first members, a query message for inquiring about final payment intention for 'home care service product 1' may be transmitted.

Accordingly, when information on '70,000 (KRW) and the inquiry message are received at the member terminals of each of the '20 first members', each of the '20 first members' will receive the query message. In response to the message, a feedback message regarding whether to proceed with payment for 'home care service product 1' may be input to the member terminal of each of the first members of the '20'.

At this time, at least one second member of the '20 first members' inputs a feedback message indicating that payment for 'home care service product 1' is to be proceeded to the member terminal of each of the second members In the case of doing so, the member terminal of each of the second members may transmit, to the group purchase platform service server 110 , a confirmation message indicating that payment for the 'home care service product 1' is to be proceeded.

In this way, in response to the inquiry message, when a confirmation message indicating that payment for the first home care service product is to be performed is returned from the member terminal of each of the second members of at least one of the first members, the payment means The information requesting unit 115 requests transmission of payment method information for payment of the first home care service product to the member terminal of each of the at least one second member.

At this time, according to an embodiment of the present invention, the payment method information request unit 115 includes the price confirmation unit 118 , the first transmission request unit 119 , the query message retransmission unit 120 , and the second transmission request unit ( 121) may be included.

In response to the inquiry message, the price confirmation unit 118 checks the number of the at least one second member when the confirmation message is received from each member terminal of the at least one second member among the first members. Then, with reference to the price table, whether a second price corresponding to a range value of the target number of group purchases to which the number of the at least one second member belongs among the plurality of prices matches the first price Check it.

When it is confirmed that the second price matches the first price, the first transmission request unit 119 sends to the member terminal of each of the at least one second member for payment of the first home care service product. Request to send payment method information.

When it is determined by the price check unit 118 that the second price does not match the first price, the query message retransmission unit 120 sets the second price to collectively purchase the first home care service product. After reconfirming the price, a query message for inquiring about payment for the first home care service product is retransmitted while transmitting the information on the second price to the member terminal of each of the at least one second member. .

In response to the retransmitted inquiry message, the second transmission request unit 121 receives a confirmation message indicating that payment for the first home care service product is to be proceeded from all member terminals of each of the at least one second member. In response, the request is made to transmit payment method information for payment of the first home care service product to the member terminal of each of the at least one second member.

Hereinafter, the operations of the price check unit 118 , the first transmission request unit 119 , the query message retransmission unit 120 , and the second transmission request unit 121 will be described in detail, for example.

First, as in the above example, the first price is '70,000 (won)', and the inquiry message is sent to the member terminals of each of the '20 first members' by the inquiry message transmission unit 114. After being transmitted, it is assumed that the confirmation message is received from the member terminals of each of the '16 second members' among the '20' first members in response to the query message.

Then, the price check unit 118 refers to the price table as shown in Table 2, and among the plurality of prices, the price corresponding to the range value of the target number of group purchases to which '16 people', which is the number of the second members, belong. After confirming the second price as '70,000 (KRW)', it may be checked whether the second price '70,000 (KRW)' matches the first price '70,000 (KRW)'.

In this embodiment, since the second price of '70,000 (KRW)' coincides with the first price of '70,000 (KRW)', there is no change in the group purchase price, so the first transmission request unit 119 is It is possible to request transmission of payment method information for payment of 'home care service product 1' to each member terminal of the '16 second members'.

However, unlike the example described above, after the inquiry message is transmitted to the member terminals of each of the first members of the '20' by the inquiry message transmission unit 114, in response to the inquiry message, the '20 Assume that the confirmation message is received only from the member terminals of each of the second members of '12' among the first members of 'person'.

Then, in the price table as shown in Table 2 above, among the plurality of prices, the second price corresponding to the range value of the target number of group purchases to which '12', which is the number of the second members, belongs is '100,000 (KRW)'. Since it is recorded as , the price confirmation unit 118 may confirm that the second price of '100,000 (KRW)' does not match the first price of '70,000 (KRW)'. In other words, because the number of members who wish to participate in the actual group purchase has decreased, the initially confirmed group purchase price of '70,000 (KRW)' has been changed to '100,000 (KRW)'.

In this way, when the group purchase price changes from '70,000 (KRW)' to '100,000 (KRW)', the query message retransmission unit 120 transmits '100,000 (KRW)' to the group purchase for 'Home Care Service Product 1' After reconfirming the price, while transmitting information about '100,000 (KRW)' to the member terminals of each of the second members of the '12' You can resend the query message.

Correspondingly, when it is said that a confirmation message indicating that payment for 'home care service product 1' is to be proceeded is returned from all member terminals of each of the '12 second members', the second transmission request unit ( 121) may request transmission of payment method information for payment of 'home care service product 1' to each member terminal of the '12 second members'.

In this way, when transmission of payment method information for payment of the first home care service product is requested to the member terminal of each of the at least one second member through the payment method information request unit 115, the at least one Each member terminal of each of the second members may transmit payment method information such as 'credit card information' or 'check card information' to the group purchase platform service server 110 in response to the request for transmission of the payment method information.

Accordingly, when payment method information for payment of the first home care service product is received from the member terminal of each of the at least one second member to the group purchase platform service server 110, the payment processing unit 116 after performing user authentication for each of the at least one second member, based on the payment method information received from the member terminal of each of the at least one second member, pay for the first home care service product to process

At this time, according to an embodiment of the present invention, the payment processing unit 116 includes the mapping matrix storage unit 122 , the authentication event generation unit 123 , the random generation unit 124 , the encryption matrix generation unit 125 , and the feedback It may include a command transmission unit 126 and an authentication completion unit 127 .

In the mapping matrix storage unit 122, a plurality of members (141, 142, 143) each of the member terminals (151, 152, 153) and pre-shared nxn (n is a natural number equal to or greater than 2) size mapping (mapping) The matrix is stored.

Here, the mapping matrix is a matrix composed of components of '1' and '0', and is pre-stored in the member terminal of each member, ^{and among n 2} components constituting the mapping matrix, t (t is 2 or more) n ² is a natural number less than 2) components are designated as '1', and the remaining n ² -t components are designated as '0'.

'과 같다고 하는 경우, 매핑 행렬 저장부(122)에는 상기 매핑 행렬인 '

'이 저장되어 있을 수 있다. For example, let n be '3' and t be '4', and '3 x 3' size that is pre-shared with the plurality of members 141, 142, 143 and the member terminals 151, 152, 153 of each. The mapping matrix of '

', the mapping matrix storage unit 122 stores the mapping matrix '

' may be stored.

When payment method information for payment of the first home care service product is received from the member terminal of each of the at least one second member, the authentication event generating unit 123 is configured to provide information for each of the at least one second member. An authentication event is generated to perform user authentication.

When the authentication event is generated by the authentication event generator 123 , the random generator 124 randomly generates t authentication codes and n ² -t dummy codes.

^{When the t authentication codes and the n 2} -t dummy codes are generated by the random generator 124 , the encryption matrix generator 125 ^{generates n 2} components constituting the mapping matrix in the mapping matrix. t s of the two components that have a "1" is assigned, with the t sets of the authentication code of one substitution, and "0" is the component of the n -t ² is designated, n ² -t dummy code by By substituting one by one, an encryption matrix of size nxn is generated.

When the encryption matrix is generated by the encryption matrix generator 125, the feedback command transmission unit 126 transmits the encryption matrix to the member terminals of each of the at least one second member to configure the encryption matrix A feedback command instructing to extract t authentication components from among n ² components and to feed them back to the collective purchase platform service server 110 is transmitted.

Hereinafter, operations of the authentication event generator 123 , the random generator 124 , the encryption matrix generator 125 , and the feedback command transmitter 126 will be described in detail, for example.

First, after transmission of payment method information for payment of the first home care service product is requested by the payment method information request unit 115 to each member terminal of the at least one second member, the at least one When it is said that payment method information for payment of the first home care service product has been received from the member terminals of each of the second members, the authentication event generating unit 123 determines the user for each of the at least one second member. An authentication event for performing authentication may be generated.

Then, the random generator 124 randomly generates '4' authentication codes such as 'P1, P2, P3, P4' and '5' dummy codes such as 'D1, D2, D3, D4, D5'. can be created

'에서, 상기 매핑 행렬을 구성하는 '9'개의 성분들 중 '1'이 지정되어 있는 '4'개의 성분들을, '4'개의 제1 인증 코드들로 하나씩 치환하고, '0'이 지정되어 있는 '5'개의 성분들을, '5'개의 제1 더미 코드들로 하나씩 치환함으로써, '3 x 3' 크기의 제1 암호화 행렬을 생성할 수 있다. Then, the encryption matrix generation unit 125 is the mapping matrix '

', '4' of the '1' of the '9' components constituting the mapping matrix are replaced one by one with '4' first authentication codes, and '0' is specified, A first encryption matrix having a size of '3 x 3' may be generated by substituting '5' components in the '5' first dummy codes one by one.

At this time, the encryption matrix generating unit 125 may replace '4' components to which '1' is specified among the '9' components constituting the mapping matrix with '4' first authentication codes. In this case, one by one may be sequentially substituted in the direction from the left column to the right column and from the upper row to the lower row. That is, in the mapping matrix, the encryption matrix generator 125 generates '1 row 1 column, 1 row 2 columns, 1 row 3 columns, 2 rows 1 column, 2 rows 2 columns, 2 rows 3 columns, 3 rows 1 column, In the order of 3 rows, 2 columns, 3 rows and 3 columns, '1' among the components may be substituted with '4' first authentication codes one by one.

'의 '1행 1열'의 성분은 '1'이므로, 암호화 행렬 생성부(125)는 상기 매핑 행렬의 '1행 1열'의 성분을, '4'개의 제1 인증 코드들 중 하나인 'P1'로 치환할 수 있다. 또한, 상기 매핑 행렬의 '1행 2열'의 성분은 '0'이므로, 암호화 행렬 생성부(125)는 상기 매핑 행렬의 '1행 2열'의 성분을, '5'개의 제1 더미 코드들 중 하나인 'D1'로 치환할 수 있다.In this regard, the mapping matrix '

Since the component of '1 row, 1 column' of ' is '1', the encryption matrix generator 125 converts the component of '1 row and 1 column' of the mapping matrix to one of '4' first authentication codes. It can be substituted with 'P1'. In addition, since the component of '1 row 2 column' of the mapping matrix is '0', the encryption matrix generator 125 sets the component of '1 row 2 column' of the mapping matrix to '5' first dummy codes. It can be substituted with 'D1', which is one of them.

'에서, 상기 매핑 행렬을 구성하는 '9'개의 성분들 중 '1'이 지정되어 있는 '4'개의 성분들을, 'P1, P2, P3, P4'로 하나씩 치환하고, '0'이 지정되어 있는 '5'개의 성분들을, 'D1, D2, D3, D4, D5'로 하나씩 치환함으로써, '3 x 3' 크기의 암호화 행렬을 '

'와 같이 생성할 수 있다. In this way, the encryption matrix generation unit 125 is the mapping matrix '
