     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0028]    In the following detailed description, only certain exemplary embodiments of the present invention have been shown and described, simply by way of illustration. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive. Like reference numerals designate like elements throughout the specification. 
         [0029]    In the specification, unless explicitly described to the contrary, the word “comprise” and variations such as “comprises” or “comprising”, will be understood to imply the inclusion of stated elements but not the exclusion of any other elements. 
         [0030]    In the present specification, online shopping means an action of purchasing a product by a purchaser through online. For example, the online shopping may be Internet shopping in which a purchaser visits a shopping mall established on the internet and purchases a product by using a computer or home shopping in which a purchaser purchases a product by using a home shopping broadcasting. The online shopping may be called Internet shopping, home shopping, cyber shopping, electronic shopping, open mall, electronic commerce, etc.  FIG. 1  is a diagram illustrating a service environment of a logistics support system for online shopping according to an exemplary embodiment of the present invention. 
         [0031]    Referring to  FIG. 1 , the service environment  1000  of the logistics support system includes a purchaser terminal  100 , a sales company server  200 , a logistics support system  300 , a supply company system  400 , and a delivery service company system  500 . 
         [0032]    The purchaser terminal  100 , which is a terminal of a purchaser who purchases a product through the online shopping, may be a Personal Computer (PC), a telephone, a mobile terminal, etc. 
         [0033]    The sales company server  200  may be a server of a home shopping company selling products or a server of an Internet shopping mall. The logistics support system  300  receives product order information input through the purchaser terminal  100  from the sales company server  200  and transfers the product order information to the supply company system  400  or the delivery service company system  500 . The logistics support system  300  supports a general procedure for distribution of the product, which will be described in detail later. 
         [0034]    The supply company system  400  means a manufacturing company system or a vendor system supplying the product. In the present specification, the supply company system  400  may designate a terminal used in the supply company, as well as a server operated by the supply company. 
         [0035]    The delivery service company system  500  means a system of a delivery service company which delivers a product to a purchaser. The delivery service company system  500  may designate a terminal used in the delivery service company, as well as a server operated by the delivery service company. 
         [0036]    When the purchaser terminal  100  accesses the sales company server  200  and places an order for a product, the sales company server  200  may release the product itself, make the product to be delivered through the delivery service company system  500 , or make the product to be delivered through the supply company system  400 . When the sales company server  200  makes the product to be delivered through the supply company system  400 , the supply company system  400  may directly deliver the product or make the product to be delivered through the delivery service company system  500 . For this purpose, it is required to transfer delivery information containing personal information on the purchaser(the sender) and/or the recipient(the receiver) to the supply company system  400  or the delivery service company system  500 . In this specification, the personal information means personal information on at least one of a purchaser, a sender and a recipient. 
         [0037]    As described above, when the product is delivered through the supply company system  400  or the delivery service company system  500 , a risk that the personal information on the purchaser and/or the receiver will be leaked is increased. Accordingly, the logistics support system  300  relays the sales company server  200 , the supply company system  400 , and the delivery service company system  500 , so that the risk of the personal information leakage may be minimized. 
         [0038]    The logistics support system  300  may be connected with the sales company server  200 , the delivery service company system  500 , and the supply company system  400  through an Electronic Data Interchange (EDI) interface. The EDI means a standard of data and documents designated for efficiently exchanging data between companies. 
         [0039]      FIG. 2  is a block diagram illustrating an internal structure of the logistics support system  300  according to an exemplary embodiment of the present invention. 
         [0040]    Referring to  FIG. 2 , the logistics support system  300  includes an information management module  310 , a security management module  320 , a waybill output management module  330 , and a delivery management module  340 . 
         [0041]    The information management module  310  may store and manage the product order information, product recovery information, complaint reception information, etc. received from the sales company server  200 . Further, the information management module  310  may store and manage product stock information, product release information, etc. received from the supply company system  400 . Further, the information management module  310  may store and manage usable range information for a waybill number, product delivery information, etc. received from the delivery service company system  500 . 
         [0042]    The security management module  320  provides the supply company system  400  or the delivery service company system  500  with encrypted personal information. For this purpose, the security management module  320  may be implemented with an EDI client connected to an EDI server and the sales company server  200 . The EDI client may be installed within the sales company server  200 . That is, when the logistics support system  300  receives a request for output of the waybill from the supply company system  400  or the delivery service company system  500 , the EDI server of the logistics support system  300  may make a request for the personal information on the purchaser and/or the receiver to the EDI client connected to the sales company server  200 . The EDI client may encrypt the personal information received from the sales company server  200  and transmit the encrypted personal information to the EDI server. 
         [0043]    When the waybill output management module  330  receives the request for output of the waybill from the supply company system  400  or the delivery service company system  500 , the waybill output management module  330  may generate waybill output information necessary for the output of the waybill and transmit the generated waybill output information to the supply company system  400  or the delivery service company system  500 . That is, the waybill output management module  330  may generate the waybill output information by using the product order information or the product recovery information and the waybill number range information stored in the information management module  310  and the encrypted personal information received from the security management module  320 . Further, a decoding function may be further included such that the encrypted personal information is decoded and outputted through an output device connected to the supply company system  400  or the delivery service company system  500 . Accordingly, the logistics support system  300  transmits the waybill output information containing the encrypted personal information to the supply company system  400  or the delivery service company system  500 , and the supply company system  400  or the delivery service company system  500  decodes and outputs the encrypted personal information, thereby being capable of preventing the bulk leakage of the personal information. 
         [0044]    The delivery management module  340  may store and manage product delivery-related information received from the supply company system  400  or the delivery service company system  500  and notify the sales company server  200  of the product delivery-related information. 
         [0045]    Hereinafter, a logistics support method of the logistics support system  300  in a case where the sales company server  200  delivers the product through the supply company system  400  will be described in detail. 
         [0046]      FIG. 3  is a flowchart illustrating a logistics support method of a logistics support system according to an exemplary embodiment of the present invention. 
         [0047]    Referring to  FIG. 3 , the logistics support system  300  receives a usable range for a waybill number from at least one delivery service company system  500  (S 300 ). The usable waybill number range may include at least one waybill number. The logistics support system  300  may store a pre-arranged waybill number range in the information management module  310  for each delivery service company. 
         [0048]    In the meantime, when the purchaser terminal  100  accesses the sales company server  200  and places an order for a product (S 310 ), the sales company server  200  transmits product order information, except for personal information on a purchaser and/or a receiver, to the logistics support system  300  (S 320 ). For example, the product order information may be at least one among a product name, the number of products, and a date of the order. The logistics support system  300  may store the product order information received from the sales company server  200  in a DB. 
         [0049]    When the logistics support system  300  transfers the product order information received from the sales company server  200  to the supply company system  400  (S 330 ), the supply company system  400  makes a request for output of the waybill to the logistics support system  300  (S 340 ). For this purpose, the supply company system  400  may confirm the product order information by accessing a web page of the logistics support system  300 , check stock, and then make the request for the output of the waybill through a web page of the logistics support system  300 . 
         [0050]    Accordingly, the logistics support system  300  makes a request for personal information corresponding to the product order information to the sales company server  200  (S 350 ), and the sales company server  200  transmits the personal information to the logistics support system  300  (S 360 ). Here, the personal information may be at least one among a name, a telephone number, an address, an email address, a resident registration number, and a birthdate of the purchaser and/or the receiver. Although it is not illustrated, the sales company server  200  may be connected with the EDI client of the logistics support system  300 , and the personal information provided by the sales company server  200  may be encrypted in the EDI client. 
         [0051]    The logistics support system  300  generates waybill output information by collecting the encrypted personal information, the product order information, and the waybill number (S 370 ). Here, the waybill number may be one of the waybill numbers belong to the usable waybill number range pre-acquired from the delivery service company system  500  in step S 300 . When the logistics support system  300  receives the request for the output of the waybill from the supply company system  400 , the logistics support system  300  may allocate the waybill number out of the usable waybill number range pre-acquired from the delivery service company system  500  to the product order information received from the sales company server  200 . 
         [0052]    The logistics support system  300  transmits the generated waybill output information to the supply company system  400  (S 380 ), and the supply company system  400  outputs the waybill by decoding the encrypted personal information (S 390 ). For example, when the supply company system  400  makes the request for the output of the waybill through the web page of the logistics support system  300  in step S 340 , the logistics support system  300  may transfer the waybill output information containing the encrypted personal information, the product order information, and the waybill number to a decoding module executed in a corresponding web browser and the decoded information may be transmitted to an output device connected to the supply company system  400 . For another example, a decoding module may be mounted in an output device connected to the supply company system  400 . Here, the output device of the supply company system  400  may be a printer, a PC monitor, or a screen of a portable terminal. The encrypted personal information transmitted to the supply company system  400  may be discarded such that the encrypted personal information cannot be restored to its original state in a memory. 
         [0053]    Then, the logistics support system  300  may transmit the waybill number to the sales company server  200 . Accordingly, when the purchaser terminal  100  makes an inquiry about delivery information by accessing the sales company server  200 , the sales company server  200  may display the delivery information indicating that the corresponding product is being delivered. 
         [0054]    Hereinafter, a logistics support method of the logistics support system  300  in a case where the sales company server  200  makes the delivery service company system  500  to deliver the product without passing through the supply company system  400  will be described in detail. Description repeated in the description in relation to  FIG. 3  will be omitted. 
         [0055]      FIG. 4  is a flowchart illustrating a logistics support method of the logistics support system according to another exemplary embodiment of the present invention. 
         [0056]    Referring to  FIG. 4 , the logistics support system  300  receives a usable range for a waybill number from at least one delivery service company system  500  (S 400 ). 
         [0057]    In the meantime, when the purchaser terminal  100  accesses the sales company server  200  and places an order for a product (S 410 ), the sales company server  200  transmits product order information, except for personal information on a purchaser and/or a receiver, to the logistics support system  300  (S 420 ). 
         [0058]    When the logistics support system  300  transfers the order product information received from the sales company server  200  to the delivery service company system  500  (S 430 ), the delivery service company system  500  makes a request for output of the waybill to the logistics support system  300  (S 440 ). For this purpose, the delivery service company system  500  may confirm the product order information by accessing a web page of the logistics support system  300  and then make the request for the output of the waybill through a web page of the logistics support system  300 . 
         [0059]    Accordingly, the logistics support system  300  makes a request for personal information corresponding to the product order information to the sales company server  200  (S 450 ), and the sales company server  200  transmits the personal information to the logistics support system  300  (S 460 ). Here, the personal information may be at least one among a name, a telephone number, an address, an email address, a resident registration number, and a birthdate of the purchaser and/or the receiver of the product. Although it is not illustrated, the sales company server  200  may be connected with the EDI client of the logistics support system  300 , and the personal information provided by the sales company server  200  may be encrypted in the EDI client. 
         [0060]    The logistics support system  300  generates waybill output information by collecting encrypted personal information, the product order information, and the waybill number (S 470 ). Here, the waybill number may be one of waybill numbers belong to the usable waybill number range pre-acquired from the delivery service company system  500  in step S 400 . When the logistics support system  300  receives the request for the output of the waybill from the delivery service company system  500 , the logistics support system  300  may allocate the waybill number out of the usable waybill number range pre-acquired from the delivery service company system  500  to the product order information received from the sales company server  200 . 
         [0061]    The logistics support system  300  transmits the generated waybill output information to the delivery service company system  500  (S 480 ), and the delivery service company system  500  outputs the waybill by decoding the encrypted personal information (S 490 ). For example, when the delivery service company system  500  makes the request for the output of the waybill through the web page of the logistics support system  300  in step S 440 , the logistics support system  300  may transfer the waybill output information containing the encrypted personal information, the product order information, and the waybill number to a decoding module executed in a corresponding web browser and the decoded information may be transmitted to an output device connected to the delivery service company system  500 . For another example, a decoding module may be mounted in an output device connected to the delivery service company system  500 . Here, the output device of the delivery service company system  500  may be a printer, a PC monitor, or a screen of a portable terminal. The encrypted personal information transmitted to the delivery service company system  500  may be discarded such that the encrypted personal information cannot be restored to its original state in a memory. 
         [0062]    In the meantime, after the product is delivered to the purchaser and/or the receiver, the purchaser and/or the receiver may desire to return or exchange the product. For this purpose, the purchaser and/or the receiver may make a request for product recovery to the sales company server  200  through the purchaser terminal  100 . Hereinafter, a logistics support method in recovering the product will be described in detail. The recovering the product means withdrawing the product. 
         [0063]      FIG. 5  is a flowchart illustrating a logistics support method of a logistics support system according to another exemplary embodiment of the present invention. 
         [0064]    Referring to  FIG. 5 , the logistics support system  300  receives a usable range for a waybill number from at least one delivery service company system  500  (S 500 ). The usable range for a waybill number may include at least one waybill number. For example, the logistics support system  300  may periodically receive the waybill number range from at least one delivery service company system  500 . For another example, when the predetermined number or less of waybill numbers allocatable for the product delivery or the product recovery is left, the logistics support system  300  may make a request for the waybill number range to the delivery service company system  500 . 
         [0065]    In the meantime, when the purchaser terminal  100  accesses the sales company server  200  and makes a request for the recovery of a product (S 510 ), the sales company server  200  transmits product recovery information, except for personal information on a purchaser and/or a receiver, to the logistics support system  300  (S 520 ). When the purchaser and/or the receiver desires to exchange or return the product, the purchaser terminal  100  may make the request for the recovery of the product. For example, the product recovery information may be at least one among a product name, the number of products, and a date of the recovery request. 
         [0066]    When the logistics support system  300  transfers the product recovery information received from the sales company server  200  to the delivery service company system  500  (S 530 ), the delivery service company system  500  notifies the sales branch office of a delivery service company which will collect the product corresponding to the product recovery information (not shown). 
         [0067]    When the sales branch office of the delivery service company accesses the delivery service company system  500  and makes a request for output of the waybill, the delivery service company system  500  makes the request for the output of the waybill to the logistics support system  300  by accessing the logistics support system  300  (S 540 ). 
         [0068]    Accordingly, the logistics support system  300  makes a request for personal information corresponding to the product recovery information to the sales company server  200  (S 550 ), and the sales company server  200  transmits the personal information to the logistics support system  300  (S 560 ). Although it is not illustrated, the sales company server  200  may be connected with the EDI client of the logistics support system  300 , and the personal information provided by the sales company server  200  may be encrypted in the EDI client. 
         [0069]    The logistics support system  300  generates waybill output information by collecting the encrypted personal information, the product recovery information, and the waybill number (S 570 ). Here, the waybill number may be one of waybill numbers belong to the usable waybill number range pre-acquired from the delivery service company system  500  in step S 500 . When the logistics support system  300  receives the request for the output of the waybill from the delivery service company system  500 , the logistics support system  300  may allocate the waybill number pre-acquired from the delivery service company system  500  to the product recovery information received from the sales company server  200 . 
         [0070]    The logistics support system  300  transmits the generated waybill output information to the delivery service company system  500  (S 580 ), and the delivery service company system  500  or the sales branch office outputs the waybill by decoding the encrypted personal information (S 590 ). 
         [0071]    Then, the logistics support system  300  may transmit the waybill number to the sales company server  200 . 
         [0072]      FIG. 6  is a flowchart illustrating a logistics support method of the logistics support system according to another exemplary embodiment of the present invention. 
         [0073]    Referring to  FIG. 6 , when the purchaser terminal  100  accesses the sales company server  200  and makes a request for the recovery of a product (S 600 ), the sales company server  200  transmits product recovery information, except for personal information on a purchaser and/or a receiver, to the logistics support system  300  (S 610 ). When the purchaser and/or the receiver of the product desires to exchange or return the product, the purchaser terminal  100  may make the request for the recovery of the product. For example, the product recovery information may be at least one among a product name, the number of products, and a date of the recovery request. 
         [0074]    When the logistics support system  300  transfers the product recovery information received from the sales company server  200  to the delivery service company system  500  (S 620 ), the delivery service company system  500  notifies the sales branch office of a delivery service company to collect the product corresponding to the product recovery information (not shown). 
         [0075]    When the sales branch office of the delivery service company desires to output the waybill, the delivery service company system  500  makes a request for personal information on a sender corresponding to the product recovery information by accessing the logistics support system  300  (S 630 ). 
         [0076]    Accordingly, the logistics support system  300  makes a request for the personal information corresponding to the product recovery information to the sales company server  200  (S 640 ), and the sales company server  200  transmits the personal information to the logistics support system  300  (S 650 ). Although it is not illustrated, the sales company server  200  may be connected with the EDI client of the logistics support system  300 , and the personal information provided by the sales company server  200  may be encrypted in the EDI client. 
         [0077]    The logistics support system  300  transmits the encrypted personal information to the delivery service company system  500  (S 660 ). The delivery service company system  500  generates waybill output information by collecting the encrypted personal information, the product recovery information, and the waybill number (S 670 ), and outputs the waybill by decoding the encrypted personal information (S 680 ). 
         [0078]    Although it is not illustrated, when a complaint is received from the purchaser, it may be processed in a similar manner to that of the recovery procedure. 
         [0079]    That is, when the delivery for the purchaser is delayed, the purchaser terminal  100  may make a complaint by accessing the sales company server  200 . For example, the making of the complaint is to make a complaint against the supply company before the delivery service company actually picks up the product after a supply company outputs the waybill, and the making of the complaint is to make a complaint against the delivery service company before the delivery service company delivers the product to the purchaser after the delivery service company picks up the product. 
         [0080]    When the complaint is received from the purchaser terminal  100 , the sales company server  200  transmits complaint information, except for personal information, to the logistics support system  300 . Here, the complaint information may include at least one among a name of the product, the number of products, a date of the product order, the waybill number, and information on the supply company making a release delay or information on the delivery service company making a delivery delay. 
         [0081]    When the logistics support system  300  transmits the complaint information to the supply company system  400  or the delivery service company system  500 , the supply company system  400  or the delivery service company system  500  may make a request for the personal information for handling the complaint. 
         [0082]    Accordingly, the logistics support system  300  may make the request for the personal information for the corresponding complaint to the sales company server  200 , and the sales company server  200  may transmit encrypted personal information to the logistics support system  300  through the EDI client. Then, the logistics support system  300  may decode the encrypted personal information and complaint information and output the decoded personal information and complaint information on a screen of the supply company system  400  or the delivery service company system  500 . 
         [0083]    As described above, the logistics support system  300  receives the encrypted personal information through the EDI client connected to the sales company server  200  in the delivery of the product, the recovery of the product, and the handling of the complaint and transmits the received encrypted personal information to the supply company system  400  or the delivery service company system  500 , so that it is possible to prevent the bulk leakage of the personal information.

Alternatively, the above-mentioned exemplary embodiments may be embodied by a program performing functions, which correspond to the configuration of the exemplary embodiments of the present invention, or a recording medium on which the program is recorded.
