Hereinafter, with reference to FIG. 2, a virtual transaction settlement method using a color code according to an embodiment of the present invention will be described in more detail.

FIG. 2 is a flowchart for generating a color code in a virtual transaction settlement system using a color code according to an exemplary embodiment of the present invention. FIG. 3 is a flowchart illustrating a method for generating a color code according to an embodiment of the present invention. And checking the information included in the color code by scanning.

2, a virtual transaction settlement method using a color code according to an exemplary embodiment of the present invention is a method in which a first user 1 is connected to a first user 1 and a second user 2 offline And requests a transaction to the first user terminal 110 (S110). At this time, the user can request a transaction to the first user (1) application installed in the first user terminal 110. [

The first user (1) application of the first user terminal (110), which is requested to make a transaction determined offline, transmits to the first user server (210), transaction details corresponding to the transaction request, (Step S120). In this case, in order to approve the access to the first user server 210, an approval request of the first user 1 is transmitted together with the identification information of the first user 1 (S120).

The first user server 210 confirms the access authorization request using the identification information of the first user 1 or the encryption key stored in the first user terminal 110 , And if the first user 1 is confirmed, the information transmitted by the first user terminal 110 is recorded in a database (not shown) of the server and color-coded (S130).

At this time, the first user server 210 generates a transaction message corresponding to at least one identification information and transaction content received from the first user terminal 110, and transmits the transaction information corresponding to the first user (1) For the information that is determined to require security in the transaction message, encryption may be performed first, followed by color coding.

For example, if the server requires security for information including at least one of the transaction details, the electronic money information, the web wallet address, the general purse address, and the identification number of the user terminal among the identification information, When it is determined that there is no possibility of possibility, such artist information and work information can be encoded into color codes having code values.

Then, the first user server 210 transmits the color code to the first user terminal 110 (S140), and the first user terminal 110 transmits the color code to the first user terminal 110 On the display unit (S150).

At this time, the color code used is a code that is implemented in a two-dimensional matrix form using a combination of a plurality of different colors and lightness differences, and stores digital information.

In particular, when a code value composed of numbers in the color code is identified, the server accesses the server corresponding to the code value using the checked code value, searches the database (not shown) associated with the server, To the terminal connected to the terminal, and can display the digital information.

At this time, the code value in the color code used is index information indicating the position where the contents information is stored.

That is, when the second user terminal 120 scans the color code displayed on the first user terminal 110 (S310), if the code value exists (S312), the second user terminal 120 And then accesses the first user server 210 corresponding to the code value, searches for the corresponding information at the location of the information stored in the code value, and receives the information at step S314.

Accordingly, the first user server 210 transmits information including at least one of the first user server 210 information, the first user (1) identification information, and the transaction message to a 5X5 matrix type color code , And these color codes may be composed of a data area, an error verification area, and a direction detection area. At this time, depending on the data amount of the information to be coded, it may be composed of 4X6, 7X5, 8X5 matrix in addition to 5X5 matrix.

However, unlike the above, the first user server 210 may store information including at least one of the first user server 210 information, the first user (1) identification information, and the transaction message, And encrypts the information before it is coded, and then encodes the encrypted information into a color code if the security module 210 determines that security is needed or that there is a possibility of being stolen by someone else. At this time, the color code to be used is not the index information indicating the storage position of the content information described above, but the content information is directly encoded, and is composed of the direction detection area, the reference cell area, and the data area. In addition, the color code is expressed in a 5X5 matrix form by combining the four colors described above, and can be expressed in a 20X10 matrix form by combining 8 colors, thereby storing contents information of up to 100 bytes.

Also, the first user server 210 may encode the index information indicating the location where the information is stored, the information directly encoded and the information encoded with the encrypted information, into one color code.

Therefore, it is possible to increase security of specific personal information, which is important for security among the plurality of first user server 210 information, first user (1) identification information, and transaction message, To encode information that is not largely related to security, or to directly encode information that is not largely related to security, or to index information that indicates a storage location of the information with respect to information having a relatively large size in comparison with other information, The user server 210 can generate color codes and code them in one color code in different ways according to the security degree of information or the size of the capacity.

The information received from the first user server 210 by the second user terminal 120 may include at least one of the first user server 210 information, the first user (1) identification information, and the transaction content message , And the information may be displayed as a message (S315).

In one embodiment of the present invention, the first user server 210 may color code information comprising at least one of the first user server 210 information, the first user (1) identification information and the transaction message 2, the first user terminal 110 can color-code information including at least one of the first user server 210 information, the first user (1) identification information, and the transaction message have.

 4 is a flowchart for generating a color code in a virtual transaction settlement system using a color code according to another embodiment of the present invention.

4, a virtual transaction settlement method using a color code according to an embodiment of the present invention is a method in which a first user 1 uses a color code in which a first user 1 and a second user 2 are offline And requests a transaction to the first user terminal 110 (S210). At this time, the user can request a transaction to the first user (1) application installed in the first user terminal 110. [

The first user (1) application of the first user terminal (110), which is requested to make a transaction determined offline, transmits to the first user server (210), transaction details corresponding to the transaction request, At this time, in order to approve the access to the first user server 210, an approval request of the first user 1 is transmitted together with the identification information of the first user 1 (S220).

The first user server 210 confirms the access authorization request using the identification information of the first user 1 or the encryption key stored in the first user terminal 110 If the first user 1 is confirmed, the information transmitted by the first user terminal 110 is recorded in a database (not shown) of the server (S230).

Thereafter, the first user server 210 may transmit confirmation information indicating that the first user 1 has been confirmed to the first user terminal 110 (S240).

The first user terminal 110 having received the confirmation information generates a transaction message corresponding to at least one identification information and transaction details received from the first user terminal 110, 1) For the information that is determined to be security in the identification information and the transaction message, encryption may be performed first, followed by color coding (S250).

For example, if the server requires security for information including at least one of the transaction details, the electronic money information, the web wallet address, the general purse address, and the identification number of the user terminal among the identification information, When it is determined that there is no possibility of possibility, such artist information and work information can be encoded into color codes having code values.

Thereafter, the first user terminal 110 displays the color code on the display unit of the first user terminal 110 (S260).

At this time, the color code used is a code that is implemented in a two-dimensional matrix form using a combination of a plurality of different colors and lightness differences, and stores digital information.

In particular, when a code value composed of numbers in the color code is identified, the server accesses the server corresponding to the code value using the checked code value, searches the database (not shown) associated with the server, To the terminal connected to the terminal, and can display the digital information.

At this time, the code value in the color code used is index information indicating the position where the contents information is stored.

That is, when the second user terminal 120 scans the color code displayed on the first user terminal 110 (S310), if the code value exists (S312), the second user terminal 120 And then accesses the first user server 210 corresponding to the code value, searches for the corresponding information at the location of the information stored in the code value, and receives the information at step S314.

Accordingly, the first user terminal 110 transmits information including at least one of the first user server 210 information, the first user (1) identification information, and the transaction message to a color code of 5X5 matrix using four colors , And these color codes may be composed of a data area, an error verification area, and a direction detection area. At this time, depending on the data amount of the information to be coded, it may be composed of 4X6, 7X5, 8X5 matrix in addition to 5X5 matrix.

However, unlike the above-described case, the first user terminal 110 may transmit information including at least one of the first user server 210 information, the first user (1) identification information, and the transaction message, And encrypts the information before it is coded, and then encodes the encrypted information into a color code if the security module 210 determines that security is needed or that there is a possibility of being stolen by someone else. At this time, the color code to be used is not the index information indicating the storage position of the content information described above, but the content information is directly encoded, and is composed of the direction detection area, the reference cell area, and the data area. In addition, the color code is expressed in a 5X5 matrix form by combining the four colors described above, and can be expressed in a 20X10 matrix form by combining 8 colors, thereby storing contents information of up to 100 bytes.

Also, the first user terminal 110 may encode the index information indicating the location where the information is stored, the information directly encoded and the encoded information, and encode the encoded information into one color code.

Therefore, it is possible to increase security of specific personal information, which is important for security among the plurality of first user server 210 information, first user (1) identification information, and transaction message, To encode information that is not largely related to security, or to directly encode information that is not largely related to security, or to index information that indicates a storage location of the information with respect to information having a relatively large size in comparison with other information, The user server 210 can generate color codes and code them in one color code in different ways according to the security degree of information or the size of the capacity.

The information received from the first user server 210 by the second user terminal 120 may include at least one of the first user server 210 information, the first user (1) identification information, and the transaction content message And the second user 2 displays the information by using a message or the like so that the second user 2 can confirm the second user 2. The second user 2 displays the message (S316).

Meanwhile, the message may be formed by the application installed in the second user terminal 120 and displayed on the second user terminal 120.

The message may be a transaction message corresponding to a transaction request determined by the first user 1 and the second user 2 to be off-line or may be a transaction message corresponding to the first user server 210 information, ) ≪ / RTI > identification information.

Meanwhile, FIG. 5 is a flowchart showing that an approval request and a transaction of transaction contents are approved based on the information that the second user terminal confirms through the color code according to an embodiment of the present invention.

The second user terminal 120 scans the color code displayed on the first user terminal 110 in step S310 and if the code value does not exist in step S313, And transmits error information to the first user server 210 through the second user server 220. [ The first user server 210 may transmit the error information to the first user terminal 110 and display the error message to the first user terminal 110.

Meanwhile, the step S316 of the second user 2 for confirming the message may include checking whether the second user 2 not only confirms the contents of the message, The user 2 requests access approval to the second user server 220 and transmits the first user server 210 information, the first user 1 identification information, the second user 2 identification information, (S320). ≪ / RTI >

The second user server 220 confirms the access authorization request using the identification information of the second user 2 or the encryption key stored in the second user terminal 120 , And if the second user 2 is confirmed, the information transmitted by the second user terminal 120 is recorded in a database (not shown) of the server (S330).

Then, the second user server 220 uses the information of the first user server 210 to identify the first user (1) identification information and transaction content recorded in the first user server 210 If the first user server 210 information, the first user information, and the transaction contents are confirmed, the second user server 220 transmits the transaction information to the second user server 220 in response to the transaction content (S340) 1 user < / RTI >

Upon receiving the transaction request, the first user server 210 transmits a transaction approval request corresponding to the transaction request to the first user terminal 110 (S350) The first user (1) application of the user terminal 110 requests a transaction signature to sign the approval for the transaction content.

Thereafter, if the first user 1 approves the transaction through the transaction signature, the first user terminal 110 transmits the transaction approval to the first user server 210 (S360) 1 user server 210 transmits the transaction approval and transaction signed contents to the second user server 220 or the distributed network 300 to transmit the transaction approval and transaction signed contents to the first user 1 and the second user 2, To complete the virtual transaction using the color code of FIG.

Meanwhile, the second user server 220 transmits a transaction request to the first user server 210 in response to the contents of the transaction, and the second user server 220 transmits the transaction request to the second user terminal 120, The second user (2) application may display a message that the transaction is being requested by the second user terminal (120).

Alternatively, the second user server 220 may use the information of the first user server 210 to identify the first user (1) identification information and the transaction content recorded in the first user server 210 If the first user server 210 information, the first user information, and the transaction details are confirmed, the second user terminal 120 transmits a transaction approval request to the second user terminal 120, The first user (1) and the second user (2) can simultaneously request the transaction approval.
