Description

SYSTEM AND METHOD FOR PROVIDING AN E-COMMERCE SERVICE BY

USING A SEPARATE EXECUTABLE FILE

Technical Field

The present invention relates to system and method for providing an E-commerce

service by using a separate executable file. More particularly, the present invention

relates to system and method for being purchased desired goods easily and quickly using

a user terminal without connecting the specified web server for providing E-commerce

service.

Background Art

As Internet circumstances are progressed, the conventional transaction method

such as buying at the real shop has been changed into the E-commerce method of

transaction between a purchaser and a seller via Internet by steps.

Hereinafter, the shape of the conventional E-commerce method will be described

in brief.

FIG. 1 illustrates the structure of carrying out the conventional E-commerce

method.

With reference to FIG. 1, the structure for carrying out the conventional E-

commerce method comprises a purchaser 110, a server 120, a seller 130 and a courier services company(e.g., FedEx Home Delivery) 140.

That is, the structure for carrying out the conventional E-commerce method

comprises the purchaser 110 who wants to purchase goods via Internet, the server 120

which transmits related information (e.g., goods information, transportation information

and the like) to the purchaser 110 via Internet and is paid the price of the selected goods by

the purchaser 110 via Internet, the seller 130 who provides the goods information and

transportation information to the purchaser 110 through the server 120 and delivers the

selected goods to the courier services company 140 in response to sale request and goods

payment, and the courier services companyl40 which transports the delivered goods to the

purchaser 110 and receives goods arrival confirmation from the purchaser 110.

Hereinafter, the E-commerce flow of the conventional E-commerce system will be

described in brief.

The server 120 having received information related to purchase, payment and the

like from the purchaser 110 transmits sale request and goods payment information to the

seller 130.

If the seller 130 receives the related information (e.g., information about purchaser,

goods and the like) or goods transportation request from the server 120, the seller 130

transmits the goods transportation request to the courier services company 140. And then,

the seller 130 transmits transportation completion information (i.e., the transportation

completion information means that the transportation of the selected goods is completed) to the server 120.

The server 120 transmits the transportation confirmation information to the

purchaser 110 using the transportation completion information received from the seller 130.

If the seller 130 gives delivered goods and delivery price to the courier services

companyl40, the courier services companyl40 delivers the received goods to the

purchaser 110. After the courier services company 140 receives goods arrival confirmation

(e.g., the recipient's signature) from the purchaser 110, the courier services company 140

transmits the goods arrival confirmation to the server 120 and the seller 130.

The seller 130 transmits the transportation completion information to the server

120 again, the server 130 transmits the transportation completion information received

from the seller 130 to the purchaser 110 again. Hereby, the E-commerce flow of the

conventional E-commerce system is ended.

But, the conventional E-commerce system has an inconvenience that the

advertisement of sorted goods only for the each of the purchaser cannot be performed and

a plurality of purchasers determine whether he purchases arbitrary goods using same goods

information.

Also, the conventional E-commerce system has an inconvenience that various

addition processes (e.g., input of payment information and so on) are required when a

purchaser purchases arbitrary goods.

Also, the conventional E-commerce system has a limit that advertising rates is increased with a result that various goods advertisements cannot be performed because of

small display of home page for providing E-commerce service.

Also, the conventional E-commerce system has a problem that a sponsor feels

distrust on advertising impact because the advertising impact does not appeared at once.

Detailed description of the preferred embodiments

Hereinafter, preferred embodiments of the present invention will be described in

more detail with reference to the accompanying drawings. And, reference numeral may be

introduced on one drawing and the same reference numeral will be utilized for the same

item regardless of drawing number.

FIG. 2 illustrates a schematic system block diagram for E-commerce service

system using a separate executable file.

With reference to FIG. 2, the E-commerce service system using a separate

executable file comprises a seller terminal 210, an E-commerce server 220, a purchaser

terminal 230 and a financial server 240. If the seller terminal 210 and the purchaser terminal 230 are able to connect the E-

commerce server 220 using communication function through the network, anything for the

seller terminal 210 and the purchaser terminal 230 can be applied without limit.

That is, although only personal computer is illustrated in FIG. 2, a mobile phone, a

personal digital assistant (PDA) and the like, too, can be applied. Hereinafter, as illustrated

in FIG. 2, case of personal computer for the seller terminal 210 and the purchaser terminal

230 will be mainly described.

The E-commerce server 220 is a server for creating advertisement message

according to advertisement message creating request of the purchaser, and closing a

contract between a purchaser and a seller at the request of the purchaser. The E-commerce

server 220 comprises processor 222 and data storing part 224.

Hereinafter, the present invention will be described in brief by referring to a

schematic system block diagram in FIG. 2.

At first, the seller terminal 210 transmits advertisement message creating request

comprising the goods information (e.g., image of goods, code of goods, price of goods and

the like) to the E-commerce server 220.

The E-commerce server 220 creates advertisement message corresponding to the

advertisement message creating request, and retrieves the relevant purchaser to transmit the

advertisement message.

And then, the E-commerce server 220 transmits the advertisement message to the retrieved purchaser through the network, and receives purchase request information for

purchasing arbitrary goods in the advertisement message from the purchaser terminal 230.

The E-commerce server 220 recognizes the electronic payment information (e.g.,

credit card information, account information, cyber money information and the like) of the

purchaser, and transmits the examination request for examining if the electronic payment

information is valid to the financial server 240.

The electronic payment information of the purchaser used by the E-commerce

server 220 is information that is inputted at joining stage in order to use the E-commerce

server 220, or information that is included in the purchase request information.

The financial server 240 may be server of Credit Card Company, bank, financial

company and the like.

And then, if the E-commerce server 220 receives the examination result about

validity of the electronic payment information from the financial server 240 through the

network and the examination result shows that the electronic payment information is valid,

the E-commerce server 220 transmits contract conclusion notice to the purchaser terminal

230, and transmits the contract conclusion notice and goods transportation request to the

seller terminal 210.

FIG. 3 illustrates a flow chart of advertisement message creating process according

to a preferred embodiment of the present invention.

Fig. 3 shows an advertisement message order process in case the sponsor can use the E-commerce server 220 as a member company.

In most cases that a sponsor requests advertisement, an entrepreneur performing

advertisement directly provides an estimate to the advertiser, and advertisement contract is

signed if the advertiser agrees.

Needless to say, the E-commerce service method using a separate executable file

according to the present invention can be applied in the same way. And, according to

circumstance, when an advertiser presents appropriate price to an entrepreneur, if the

entrepreneur admits the presented price, a method that the entrepreneur performs

advertisement can also be applied.

With reference to FIG. 3, the E-commerce server 220 examines if the

advertisement message creating request (e.g., image of goods, code of goods, price of

goods and the like) is received from the seller terminal 210 in step 310.

The advertisement message creating request received through step 310 may

include an estimate for creating and performing an advertisement. If the estimate is

included in the advertisement message creating request, the estimate can be included in the

shape of attached file or included in the message field of the advertisement message

creating request.

Hereinafter, the case that an estimate is included in the advertisement message

creating request will be mainly described.

Through the examination of the step 310, if the advertisement message creating request is received, the process proceeds to step 320. Otherwise, the process waits in step

310.

The E-commerce server 220 separates the estimate from the advertisement

message creating request in step 320, and stores the estimate in step 330.

In step 340, the E-commerce server 220 transmits a contract document for creating

and making an advertisement message to the seller terminal 210 through the network.

In step 350, the E-commerce server 220 receives agreement information (i.e.,

prepared contract document by the seller) about the contract document from the seller

terminal 210. In step 360, the E-commerce server 220 performs the electronic payment for

creating, making and transmitting an advertisement message using the seller's electronic

payment information.

The seller's electronic payment information may be included the advertisement

message creating request received through the step 310, or included in the personal

information inputted at joining stage in order to use the E-commerce server 220.

As above described referring to FIG. 2, the electronic payment performed through

the step 360 can be performed through the approval of an additional financial server.

In step 370, the E-commerce server 220 analyzes member company's preference

and plan for making advertisement message using related information (e.g., the seller's

personal information) stored in the data storing part 224. And then, the E-commerce server

220 creates and makes advertisement message in step 380. The advertisement message created through the step 380 can include a contract

document and an encryption module for protecting the information (e.g., user ID, password

and the like) transmitted from the seller terminal 210. And, the advertisement message can

be in the shape of separate executable file (i.e., file extension of 'XXX.exe')

In step 390, the E-commerce server 220 stores the advertisement message created

through the step 380.

FIG. 4 illustrates a flow chart of advertisement message transmittmg process to

purchaser according to a preferred embodiment of the present invention, FIG. 5 illustrates

a flow chart of profit providing process in response to read of advertisement message

according to a preferred embodiment of the present invention.

With reference to FIG. 4, in step 410, the E-commerce server 220 retrieves

suitable advertisement message among a plurality of advertisement messages created by

the seller's request, in order to transmit to a purchaser.

In step 420, the E-commerce server 220 retrieves purchasers list stored in the data

storing part 224 in order to transmit advertisement message.

In step 430, the E-commerce server 220 transmits the advertisement message

retrieved through the step 410 to the purchaser terminal 230 using the purchasers list

retrieved through 420.

The several methods for transmitting the advertisement message through the step

430 can be applied. One method is that the purchaser reads the received advertisement message if the

advertisement message is transmitted using related information (e.g., E-mail account

information) inputted at joining stage in order to use the E-commerce server 220.

Another method is that the advertisement message is displayed automatically on a

screen coupled to the purchaser terminal 230 if the advertisement message is transmitted to

the purchaser terminal 230 using push technique.

In this case, if appropriate benefits (e.g., an accumulation of cyber money, a

discount of mobile phone charge, an offer of instant lottery and the like) are provided to

the purchaser when the purchaser reads the received advertisement message, the value and

effect of the advertisement can be maximized because the advertisement message attracts

the interest of the purchaser.

As described above, the method for providing profit to the purchaser in order to

maximize advertising impact will be described referring to FIG. 5.

With reference to FIG. 5, the E-commerce server 220 receives the perusal

information about the advertisement message from the purchaser terminal 230 in step 510,

retrieves account information (e.g., cyber money account, mobile phone charge discount

information and the like) of the purchaser transmitting the perusal information in step 520.

In step 530, the E-commerce server 220 provides predetermined profits (e.g., an

accumulation of cyber money, a discount of mobile phone charge and the like) to the

purchaser using account information retrieved through the step 520. Needless to say, in addition to the steps shown in FIG. 5, the step of examining if

the perusal information about the advertisement message received from the purchaser

terminal 230 is the perusal information about advertisement message profited already can

be further comprised. Therefore, the repeated perusal information about the same

advertisement message received can be profited within predetermined number (e.g., only

one time).

present invention.

The examples of screen display shown in FIG. 6A through FIG. 6C can be applied

in case that the purchaser executes an attached file when the purchaser terminal 230

receives advertisement message in the shape of attached file (separate executable file) in E-

ail from the E-commerce server 220, or the advertisement message is displayed

automatically on a screen using push technique when the advertisement message is

received to the purchaser terminal 230.

With reference to FIG. 6A, the logo image 610 of the seller is displayed on a

screen coupled to the purchaser terminal 230, when the purchaser executes the received

attached file (separate executable file including advertisement message) in E-mail or the

advertisement message is displayed automatically.

Needless to say, the logo image displayed on the screen coupled to the purchaser terminal 230 can be another image. The file format of the logo image can be GIF, JPEG,

GIF animation, AVI and the like, the image can be modified using mask picture control

according to the type that the user wants.

And, if the purchaser clicks the predetermined region (e.g., logo image region,

advertisement message display button and so on) of the logo image 610 using input part

(e.g., mouse), screen display shown in FIG. 6B is displayed on the screen.

With reference to FIG- 6B, a goods information window 620, included information

of goods that the seller wants to sell, is displayed in a certain region (e.g., left side) of the

logo image.

The goods information window 620 comprises image of goods that the seller

wants to sell, goods information, goods price, 'detail' button 622, 'purchase' button 624,

'next' button 626, and 'confirm' button 628.

If the purchaser selects 'detail' button 622, the purchaser terminal 230 connects

automatically to the seller's website or the website including detail information about the

goods using web utility (e.g., Internet Explorer and the like). Therefore, the purchaser can

read the detail information about the goods.

If the purchaser selects 'purchase' button 624, the screen display shown in FIG.

6C is displayed on the screen.

If the advertisement message received from the E-commerce server 220 comprises

a plurality of goods information and the purchaser selects 'next' button 626, another goods information included in the advertisement message is displayed on the screen.

If the purchaser selects 'confirm' button 628, the predetermined profits can be

provided to the purchaser as described referring to FIG. 5.

FIG. 6C illustrates an example of screen display in case that a purchaser selects

'purchase' button 622 in the goods information window 620.

That is, the 'purchase' button is button for performing purchase request about the

displayed goods using the advertisement message itself.

With reference to FIG. 6C, when the purchaser selects 'purchase' button in the

goods information window 620, a purchase request window 630 is displayed on the screen.

And the purchase request window 630 comprises blank for inputting the goods quantity

that the purchaser wants to purchase, blanks for inputting the purchaser's ID and password,

'confirm' button and 'cancel' button.

The purchaser's ID and password are connection information granted at joining

stage in order to use the E-commerce server 220, and the items for inputting the

purchaser's ID and password in the purchase request window 630 can be changed into

items for inputting secret code, item for inputting connection code and the like.

If the purchaser selects 'confirm' button after the purchaser inputs goods quantity

for purchasing goods, ID and password, the purchase request for purchasing the goods is

completed. And, if the purchaser selects 'cancel' button because the purchaser does not

want to purchase, the purchase request for purchasing goods is interrupted. Also, if various payment means (e.g., credit card, auto transfer between bank

accounts) can be used in order to pay goods price, item for selecting payment means

among a plurality of selectable payment means can be further comprised in the purchaser

has the purchase request window 630.

Needless to say, if the purchase request window 630 is not formed as additional

window shown in FIG. 6C, but the purchase request window 630 is included in the goods

information window 620, the purchaser can read goods information and input purchase

request at the same time using the goods information window 620.

FIG. 7 illustrates a flow chart of advertising message transmitting process to

purchaser according to another preferred embodiment of the present invention.

With reference to FIG. 7, in step 710, the E-commerce server 220 retrieves

relevant advertisement message among the at least one advertisement messages created by

the seller's request (shown in FIG. 3), in order to transmit advertisement message to a

purchaser terminal 230.

In step 720, the E-commerce server 220 retrieves the purchaser information stored

in the data storing part 224 in order to transmit the advertisement message.

In step 730, the E-commerce server 220 examines if the retrieved advertisement

message retrieved through the step 710 is suitable to the purchaser using the purchaser

information retrieved through the step 720.

The several methods for examining if the advertisement message retrieved through the step 730 is suitable to the purchaser can be applied as follows.

One method is that the interest field information (e.g., communication, game,

reading and the like) inputted at joining stage in order to use the E-commerce server 220 is

used.

For example, if the advertisement message includes advertisement information

about new book, the advertisement message is transmitted to the only specified purchaser

selecting reading in the interest field information.

If this method is applied, the advertisement message can be used for target

marketing.

Another method is that the E-commerce server 220 examines if the purchaser

accepts the reception of the advertisement message at joining stage.

That is, this method is that the E-commerce server 220 transmits the advertisement

message to the only purchaser accepting reception of the advertisement message.

If this method is applied, the seller and the E-commerce server 220 prevent from

transmission of unnecessary advertisement message, and the purchaser omits reception of

the undesired advertisement message.

Still another method is that the communication means information (e.g., Modem,

private network and the like) of the purchaser inputted at joining stage is used.

That is, if the purchaser terminal 230 identified using the communication means

information can display moving picture, the E-commerce server 220 transmits advertisement message including moving picture. Otherwise, the E-commerce server 220

transmits advertisement message including stopped image.

If this method is applied, the suitable advertisement message can be transmitted to

the purchaser terminal 230, unnecessary time for displaying advertisement message on the

screen can be reduced, and a plurality of separate advertisement messages can be created

from the advertisement message creating stage.

Through the examination of the step 730, if the advertisement message is suitable

to the purchaser, the E-commerce server 220 stores the purchaser information (e.g., E-mail

account, IP address and so on) in a transmission list in step 740. But, if the advertisement

message is not suitable to the purchaser, the process proceeds to step 720 again, the E-

commerce server 220 retrieves another purchaser information.

In step 750, the E-commerce server 220 examines if all of the purchaser

information stored in the data storing part 224 is retrieved.

Through the examination of the step 750, if all of the purchaser information stored

in the data storing part 224 is not retrieved, the process proceeds to step 720 again, the E-

commerce server 220 retrieves another purchaser information. But, if all of the purchaser

information stored in the data storing part 224 is retrieved, the process proceeds to step 760.

In step 760, the E-commerce server 220 transmits the advertisement message

retrieved through the step 710 to arbitrary purchaser terminal 230 included the

transmission list stored through the step 740. The case that perusal information about the advertisement message is received

after the E-commerce server 220 transmits the advertisement message to arbitrary

purchaser terminal is already described referring to FIG. 5. Therefore, duplicate description

will be omitted here.

a seller according to a preferred embodiment of the present invention.

With reference to FIG. 8, in step 810, the E-commerce server 220 receives a

purchase request (e.g., the purchase request comprises goods quantity for purchasing goods,

ID, password and the like) from the purchaser terminal 230.

Because the method for transmitting the purchaser request to the purchaser

through the step 810 is already described referring to FIG. 6A, 6B and 6C, the duplicate

description will be omitted here.

In step 820, the E-commerce server 220 examines if the connection information

(e.g., the purchaser's ID, the purchaser's password and the like) in the purchase request

received through the step 810 is valid.

In step 820, the method for examining the connection information can be, for

example, the method for examining if the connection information received through the step

810 coincides with the connection information granted at joining stage in order to use the

E-commerce server 220

Through the examination of the step 820, if the connection information is not valid, the E-commerce server 220 transmits the error message (e.g., 'the password is not correct,

retry please.') to the purchaser terminal 230 in step 830. And then, the process proceeds to

step 810 again.

But, if the connection information is valid, the process proceeds to step 840.

In step 840, the E-commerce server 220 retrieves the purchaser's payment means

information for performing electronic payment, and transmits the retrieved payment means

information to the financial server 240 in order to perform validity examination and

recognition.

Needless to say, if the payment means is the predetermined payment means (e.g.,

cyber money, reserve and the like) which are passed freely in the E-commerce server 220,

the step of transmitting the payment means information to the financial server 240 can be

omitted.

In step 850, the financial server 240 receives the payment means information from

the E-commerce server 230. And then, the financial server 240 examines if the payment

means information is valid using the credit card number, the available period, the

remainder, a purchasing limit and the like.

In step 870, the financial server 240 transmits the validity examination result

created through the validity examination of the step 860 to the E-commerce server 220.

In step 880, the E-commerce server 220 receives the validity examination result

from the financial server 240. And then, in step 890, the E-commerce server 220 examines if the payment means information is valid using the validity examination result received

through the step 870.

The examination of the step 890, if the payment means information is not valid,

the process proceeds to step 900, the E-commerce server 220 transmits an error message

(e.g., 'Your credit card is unfit for use') to the purchaser terminal 230, the process

proceeds to step 810 again.

Also, through the examination of the step 890, if the payment means information

is valid, the process proceeds to step 910, the E-commerce server 220 transmits a contract

conclusion notice to the purchaser terminal 230 and the seller.

The contract conclusion notice transmitted to the purchaser terminal 230 through

the step 910 can be, for example, a purchase request recognition completion notice, and the

contract conclusion notice transmitted to the seller through the step 910 can be, for

example, goods transportation request.

While the present invention has been particularly shown and described with

reference to preferred embodiments thereof, it will be appreciated that many variations,

modifications and other applications of the present invention may be made.

Industrial Applicability

According to the present invention, system and method for providing an E-
