1 is a view for explaining a coupon issuing system according to an embodiment of the disclosed technology.

Referring to FIG. 1, the coupon issuing system 100 includes a user terminal 110, a seller server 120, and a coupon issuing server 130. The user terminal 110, the seller server 120, and the coupon issuing server 130 may be connected to the Internet.

The user terminal 110 may include a computer or a mobile terminal capable of accessing the Internet. For example, the mobile terminal may correspond to a smartphone. The user terminal 110 may transmit the coupon number to the service server 120 in order for the user to obtain incentives from the seller. The incentive may correspond to a specific product or a specific service provided by the seller, and the specific service may include a discount of the product or service. The coupon number may include letters including an English uppercase alphabet, an English lowercase alphabet, and Arabic numerals.

The seller server 120 may be used to sell goods or provide services to the user through the Internet, and may provide incentives to the user for inducement of the user. The seller server 120 may receive a coupon number from the user in order to provide an incentive to the user. In one embodiment, the seller server 120 may be issued a coupon number from the coupon issuing server 130 in advance and distribute the issued coupon number to a specific user, if the coupon number is entered, the seller server 120 coupon number The corresponding incentive can be provided to the user.

The coupon issuing server 130 issues a coupon number and stores the coupon number in a database. The coupon number is distributed by the seller server 120 or the coupon issuing server 130. In addition, the coupon issuing server 130 provides a public validation module to the user terminal 110. The user terminal 110 executes the public verification module, and the public verification module performs offline validation of the coupon number issued by the coupon issuing server 130. That is, the public verification module verifies the coupon number without connecting the coupon issuing server 130.

FIG. 5 is a diagram for describing a process of installing a public verification module by the user terminal of FIG. 1. FIG. 5 assumes that a coupon number is input through a web browser executed in a user terminal.

In FIG. 5, the coupon number may consist of 20 characters, and the user terminal 110 may install the public verification module before the coupon number is input. In one embodiment, the public verification module may be implemented as a plugin control of a web browser, for example, the plugin control may correspond to an ActiveX control. As a result, the user terminal 110 may execute the public verification module downloaded from the coupon issuing server 130.

2 to 4 are views for explaining a process of generating a coupon number by the coupon issuing server of FIG.

Coupon issuing server 130 receives at least one identifier (step S210). In one embodiment, coupon issuing server 130 may include a service identifier for identifying a service and an item identifier for identifying an item in the service. For example, when the seller server 120 is used for music provision, the service identifier may indicate music provision and the item identifier may indicate items such as music listening and music purchase.

In one embodiment, at least one identifier may be predefined by the coupon issuing server 130, and the merchant server 120 may transmit at least one predefined identifier to the coupon issuing server 130. When the service identifier and the item identifier are predefined, the seller server 120 may transmit the service identifier and the item identifier to the coupon issuing server 130. For example, the seller server 120 may request the coupon issuing server 130 to issue k coupons, and transmit the service identifier and item identifier for each of the coupons to the coupon issuing server 130. Can be.

Coupon issuing server 130 determines a string table that defines characters with easy readability. The characters include an uppercase alphabetic alphabet, an English lowercase alphabet, and Arabic numerals, where a string table that defines a character with easy readability refers to a string table that excludes at least some characters within the English uppercase alphabet, lowercase alphabetic alphabet, and Arabic numerals. do. In one embodiment, a string table that defines characters with easy readability may refer to characters other than those with hard readability that may be confused by a user. For example, a character with difficult readability may include the Arabic numerals zero, uppercase English o, and lowercase English o, and the Arabic numerals 1 and lowercase English el. And may include Arabic numerals (2), uppercase English jets (Z), and lowercase English letters (z), and may include English uppercase letters X (X) and lowercase English letters X (x). Also, for example, letters with difficult readability may include the Arabic numeral 8 and the English capital letter ratio B.

FIG. 3 is a diagram for describing a string table that defines a character having easy readability.

In the case of FIG. 3 (a), it is a view for explaining a string table including both a character having difficult readability and a character having easy readability. The first row 310 represents a table index and the second row 320 represents a character corresponding to the corresponding table index.

3 (b) and 3 (c), a diagram illustrating a character string table including characters having easy readability without characters having difficult readability. Each of the third row 330 and the fifth row 350 represents a table index, and each of the fourth row 340 and the sixth row 360 represents a character corresponding to the corresponding table index. 3 (b) and 3 (c) correspond to an example for describing a string table including a character having easy readability without a character having difficult readability, and the coupon issuing server 130 is shown in FIG. 3 (b). ) Or only the string table shown in FIG. 3 (c).

In one embodiment, the coupon issuing server 130 may use one of a plurality of string tables (eg, FIGS. 3 (b) and 3 (c)) based on at least one identifier to display a character having easy readability. It can be selected by defining a string table. Conversely, the public verification module can determine the string table based on at least one identifier string.

The coupon issuing server 130 generates at least one identifier string corresponding to each of the at least one identifier with at least one character included in the string table (step S230). For example, when the service identifier corresponds to [0x02] and the string table in FIG. 3 (b) is selected, the coupon issuing server 130 may generate [B] as a service string corresponding to the service identifier. In addition, when the service identifier corresponds to [0x02 0x0b] and the string table shown in FIG. 3 (c) is selected, the coupon issuing server 130 may generate [4b] with a service string corresponding to the service identifier. For another example, when the item identifier corresponds to [0x01] and the string table shown in FIG. 3 (b) is selected, the coupon issuing server 130 may generate [A] with an item string corresponding to the item identifier. .

Coupon issuing server 130 generates a coupon value that can be successfully authenticated by the public verification module (step S240). That is, the coupon value is generated according to a specific rule. The characters included in the coupon value consist of at least one character included in the string table. In one embodiment, the coupon value may include at least n characters (n> 1). The coupon value generation process will be described with reference to FIG. 4.

The coupon issuing server 130 generates a coupon number based on the at least one identifier string and the coupon value (step S250). In an embodiment, the coupon issuing server 130 may generate a coupon number by appropriately arranging at least one identifier string and a coupon value. For example, if at least one identifier string corresponds to [AbdE] and the coupon value corresponds to [9d64N5b7], the coupon number may correspond to [A6b9dEN7d4b5].

The coupon issuing server 130 registers the coupon number in the database (step S260). The public verification module is used to determine whether the coupon number is appropriate while the database is used to determine whether the coupon number has already been issued.

If the coupon number is already registered in the database, the coupon issuing server 130 repeats steps S240 to S260 (step S270). If the coupon number is registered in the database, the coupon issuing server 130 may determine that the same coupon number has already been issued. This is because issuance of the same coupon number may not be allowed.

4 is a view for explaining a process of generating a coupon value in the coupon issuing server of FIG.

In FIG. 4A, it is assumed that the coupon issuing server 130 determines the service string M and the item string L as at least one identifier string. The coupon issuing server 130 places at least one identifier string at a predetermined specific position of the coupon number. In FIG. 4A, the service string M may be placed at the first index of the coupon number and the item string L may be disposed at the ninth index of the coupon number.

In FIG. 4B, the coupon issuing server 130 generates at least one first character in the selected string table based on the at least one identifier. For example, the first character may correspond to [3ayT6]. The coupon issuing server 130 may place the first letter at an appropriate position of the coupon number. In an embodiment, the coupon issuing server 130 may determine the location of the first character based on the at least one identifier. For example, each of the first characters [3ayT6] may be sequentially disposed at the third, fifth, eighth, eleventh and fourteenth.

In FIG. 4 (c), the coupon issuing server 130 is based on at least one identifier based on the first character (eg, [3ayT6]) for offline verification of the public verification module. Generate one remaining second character. The coupon issuing server 130 generates a second character using an algorithm based on the first character and the public key. Here, the reason for using the public key based algorithm is that it is used by the public verification module that is publicly distributed to the user terminal 110. In an embodiment, the coupon issuing server 130 may arrange the second character at positions other than the position of the at least one identifier and the position of the first character. For example, the coupon issuing server 130 may generate the second character [Qr5RN439F] using the first character [3ayT6] and a specific public key based algorithm.

A person skilled in the art can easily know the operation method of the public verification module based on the coupon number generation algorithm, and thus the operation method of the public verification module is omitted.

The disclosed technique may have the following effects. It is to be understood, however, that the scope of the disclosed technology is not to be construed as limited thereby, as it is not meant to imply that a particular embodiment should include all of the following effects or only the following effects.

The coupon issuing method according to an embodiment may efficiently generate a coupon number. For example, the coupon issuing method may be composed of a service identifier, an item identifier, a first coupon character, and a second coupon character generated based thereon without randomly registering any number in the database.

The coupon issuing method according to an embodiment may reduce the load on the server by verifying the coupon number offline in the user terminal before accessing the server through the public verification module. For example, the public verification module can verify the accuracy of the coupon number, and the server can verify whether the coupon number has been issued.

Although the above has been described with reference to the preferred embodiment of the present invention, those skilled in the art will be variously modified and modified within the scope of the present invention without departing from the spirit and scope of the present invention described in the claims below. It will be appreciated that it can be changed.
