CERTIFICATE BAR-CODE CIRCULATING METHOD BY MOBILE

COMMUNICATION TERMINAL AND COMPUTER READABLE MEDIUM

STORED THEREON COMPUTER EXECUTABLE INSTRUCTION FOR

PERFORMING THE SAME

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to a certificate bar-code circulating method

by mobile communication terminal and computer readable medium stored thereon

computer executable instruction for performing the same, and more particularly, to

a certificate bar-code circulating method by mobile communication terminal in

which, when a request of issuing a certificate bar-code is received; a system of

issuing agency issues various kinds of certificates possible to circulate on off-line

in a bar-code form to a mobile communication terminal that a receiver of the

certificate bar-code has and the receiver uses the issued certificate bar-code

output from a displaying portion of the mobile communication terminal when

needed, and computer readable medium stored thereon computer executable

instruction for performing the same.

(b) Description of the Related Art

Recently, on off-line, various kinds of valuable certificates certificating that

someone who has the same can purchase goods, use facilities, or receive

immaterial services such as a merchandise bond; an admission ticket for plays,

movies, sports, or else; a coupon for using sports or other facilities; a boarding

card for train or airplane, etc are issued and circulated(such various kinds of valuable certificates issued and circulated on off-line for purchasing or exchanging

goods, using facilities, or receiving services are all called certificates hereinafter).

The above-mentioned certificates are generally circulated in form of materiality

such as paper, plastic sheet, or magnetic or electronic card.

Accordingly, the certificates in form of materiality have some defects that

someone who wants to receive a certificate should visit a predetermined place to

receive a certificate and someone who has already obtained a certificate and

wants to use the same should visit a corresponding distributor with carrying the

same and present the corresponding certificate. In addition, since the distributor

should check if the certificate is true or fake by the naked eye or the computer to

provide goods or immaterial services, manpower or any equipment to verify the

certificate are required.

Recently, since the information and communication technology is rapidly

developed, the mobile communication terminal such as cellular phone, PCS

phone, etc. allowing a voice telephone call, a text message transmission, an

image transmission, a connection to internet by WAP(Wireless Application

Protocol) is widely spread. Further, the common use of IMT(lnternational Mobile

Telecommunication)-2000 terminal or CDMA(Code Division Multiple Access)-2000

terminal called as 'fantastic information and communication apparatus' are also

gradually spread.

The IMT-2000 or CDMA-2000 terminals, next generation mobile

communication terminal using a satellite, have an advantage allowing the user to

receive services such as voice telephone call, visual telephone call, telex, facsimile, radio paging, or electronic mail in any place of all over the world.

Accordingly, the present mobile communication service where the voice

communication service takes the main place will be developed to a mobile

communication service based on the IMT-2000 or CDMA-2000 terminals, which

can send and receive the high capacity of digital data packet in super-high speed

and provide multimedia contents such as moving image or music in real time.

Meanwhile, in the circulation sector of goods, bar-codes are widely used

for the systematical distribution and management of goods. The bar-codes are

roughly classified into one-dimensional bar-code and two-dimensional bar-code.

The one-dimensional bar-code is the one comprising optically readable white bars

and black bars each having different thickness one-dimensionally arranged to

systematically represent country, manufacturer, number of good, prevention of

reading error, etc. and the two-dimensional bar-code is the one comprising

optically readable information register unit two-dimensionally arranged in form of

matrix not bar to register more amount of information. Now the bar-code is

welcomed mainly in the field of distribution and management of goods since the

bar-code allows rapidly reading the information registered according to the

predetermined rule by bar-code reader and easily grasping the distribution and

management status of the goods having bar-code. However, the field using bar-

code will be diversified.

Accordingly, the present invention is to overcome the problems of the

certificate circulation method according to the conventional art by grafting the bar¬

code technology welcomed in the field of distribution and management of goods and the mobile communication technology allowing wirelessly sending and

receiving image information for the issuance and circulation of various kinds of

certificates.

system 300 for requesting the issuance of the certificate bar-code according to the

present invention; a mobile communication terminal 330 for receiving, managing

and using the certificate bar-code issued according to the present invention; a

mobile communication business proprietor system 320 for wirelessly sending the

certificate bar-code data provided by the issuing agency system 200 to the mobile

communication terminal 330 of a receiver of the certificate; and a client system

310 of a distributor dealing in the certificate bar-code issued according to the

present invention. Here, internal system resources of the issuing agency system

200 is preferably linked by local area network LAN 240 and a router(not shown) is

preferably interposed between the issuing agency system 200 and an external

network, internet, to form a network interface.

More precisely referring to the network shown in Fig. 2, the issuing agency system 200 comprises a web server 210 as a host for processing web documents

related to the issuance of the certificate bar-code according to the present

invention and communicating with external clients 300 or 310 through the internet;

a data managing server 250 for making database out of various information

interactively transmitted from the external client 300 or 310 and the external

system(not shown) which may be included in the network through business

to the present invention and effectively dispersing the amount of data processing

that the web server 210 charges with; a certificate server 260 for processing the

authentication for the client system 310 of a distributor; a first database 252 and a

second database 262 wherein a large amount of information required for

implementing the present invention is registered, updated, and deleted with being

linked with the data managing server 250 and the certificate server 260; and an

internal client system 270 for managing various system resources inside the

issuing agency system 200.

The first and second databases 252 and 262 may be build up as a

relational database, distributed database, object-oriented database, etc. The

relational database with easy extensibility is preferred, but not being limited to the

same.

More particularly, the first database 252 preferably comprises a member

information storage section for registering and managing the member's

information such as ID, secret number, identification number, address, number of

mobile communication terminal, etc.; a certificate bar-code issuing particulars information storage section for registering and managing the number of mobile

communication terminal that receives the certificate bar-code and various

information related to the issuance of the certificate bar-code such as the kind of

the first database 252 is not limited to the same.

The second database 262 preferably comprises an authentication key

information storage section wherein the authentication key of the certificate bar¬

code issued from the certificate server 260 is registered when the certificate bar¬

code is issued according to the present invention. Further, it is more preferable to

build up the authentication key information storage section to connect the

information of who requests to issue the certificate with the authentication key of

the issued certificate bar-code.

The issuing agency system 200 may further comprise a firewall server 232

or an intrusion detection server 230. In this case, the firewall server 232 is

positioned between the external network such as internet and the internal

network(the issuing agency system 200) to detect intrusion from the external

network and protect the internal network information and the system resources. In

other words, the information and the system resources of the internal network are prevented from trouble arising by not allowing access from the external network

into the internal one without passing through the firewall server 232. In addition,

the intrusion detection server 230 intercepts that a user unauthorized for the

internal network approaches to the system resources and the information requiring

security of the internal network and does illegal thing.

The user client system 300 that the requester of the certificate bar-code

uses may be a lap-top computer of a person or a company. The user client system

300 preferably comprises fundamental hardwares such as a displaying device

such as monitor, an input device such as keyboard or mouse, a processor for

processing data, a storing medium, and a communication device such as modem

or LAN card. In addition, it is preferable that an operating system supporting

graphic user interface function such as Windows series of Microsoft and a web

browser receiving various web documents provided from the web server 210 of

the issuing agency system 200 and displaying the same as a graphic interface, for

example, Explorer(trade mark) of Microsoft or Navigator(trade mark) of Netscape

are fundamentally installed in the user client system 300. On the other hand, the

user client system 300, according to circumstances, may be a mobile

communication terminal that can connect with the web server 210 of the issuing

agency system 200 through the wireless internet by the widely known wireless

internet protocol such as WAP(Wireless Application Protocol. In this case, the

issuing agency system 200 preferably comprises a WAP server 280 providing a

network interface allowing using the internal system resources of the issuing

agency through wireless internet. The client system 310 of the distributor preferably comprises a bar-code

scanner 314 for scanning the certificate bar-code issued according to the present

invention and output on the displaying portion 50 of the mobile communication

terminal I of the certificate receiver and a database of itself 312 wherein the

transmitted information is stored when the information related to the certificate

bar-code issued according to the inventive method described below is transmitted

from the issuing agency system 200 through the internet.

The database of itself 312 preferably comprises a storage section of

information about particulars of issuing the certificate bar-code and a storage

section of information about particulars of using certificate bar-code. In the storage

section of information about particulars of issuing the certificate bar-code, the

information related to the certificate bar-code transmitted from the issuing agency

system 200 is registered and in the storage section of information about

particulars of using certificate bar-code, the information about particulars of using

certificate bar-code is registered. In addition, the client system 310 of the

distributor preferably includes a decoding module allowing decoding the

information recorded in the bar-code by deciphering the certificate bar-code

scanned by the bar-code scanner 314 by using a predetermined decipherment

algorithm such as PDF 417 decipherment algorithm to be executed when required.

Fig. 3 is a flow chart showing an issuing procedure of a certificate bar¬

code according to the preferred embodiment of the present invention.

According to Fig. 3, first, a requester of a certificate accesses to the web

server 210 of the issuing agency system 200 by the user client system 300 at the stage of S10. Then, at the stage of S20, the issuing agency system 200 provides

a main web page allowing the requester's access to various web interfaces

related to the issuance of the certificate bar-code after the member authentication

of the requester to the user client system 300 through the internet. Next, the

requester navigates the main web page to approach to various web interfaces

related to the issuance of the certificate bar-code and requests a web page for

member authentication comprising the interface for member authentication. The

issuing agency system 200 provides the web page for member authentication to

the client system 300 of the requester at the stage of S30. The requester requests

the member authentication by inputting the information for member authentication,

i.e. ID and secret number. Then, the issuing agency system 200 verifies if the

requester who requests the member authentication is a registered member or not

by using the member information storage section inside the first database 252 at

the stage of S40.

When the requester is verified not to be a member at S40, a web page

comprising a member registration interface is provided for the requester to register

as a member by inputting the information required for member registration at the

stage of S40. The information input for member registration may comprise ID,

secret number, identification number, address, name, age, gender, phone number,

e-mail address, phone number of mobile communication terminal, etc. When the

requester of the certificate is verified to be a member at S40, a web page for

issuing the certificate bar-code is provided to the client system 300 of the

requester. The web page for issuing the certificate bar-code preferably comprises a web navigation including an interface for choosing the kind of certificate to be

issued and an interface for inputting the information related to the issuance of the

chosen certificate. Here, the information related to the certificate to be issued

means the information precisely defining goods, facilities, or services purchased,

used, or provided through the certificate. The precise example for the same is

described below.

When the web page for issuing the certificate bar-code is provided at the

stage of S50, the requester of the certificate determines if he/she receives the

certificate bar-code at that time at the stage of S60. When the requester

determines not to receive the certificate bar-code at that time, he/she may use

another additive services at the stage of S65, and when the requester determines

to receive the same, he/she may access the interface for choosing the kind of

certificate bar-code to be issued and the interface for inputting the information

related to the certificate issuing of the web page for issuing the certificate bar-

code and provide the information required for issuing the certificate bar-code to

the issuing agency system 200 through the internet. Hereinafter, the embodiment

of the present invention is described by specifying the certificate as an admission

ticket for movie to precisely describe the present invention. However, there is no

wonder for those skilled in the art that the certificate provided in the form of bar-

code according to the present invention is not limited to an admission ticket for

movie.

More precisely, the requester chooses an admission ticket for movie as a

certificate to be issued through the interface for choosing the kind of certificate, inputs the information required for issuing the admission ticket for movie such as

name of movie theater, number or name of screening hall, title of the movie to see,

screening date, screening time, number of tickets, etc. through the interface for

inputting the information related to the certificate issuing and provide the

information to the issuing agency system 200. Then, the requester requests a web

page for settlement including a settlement interface for paying the certificate to be

issued from the issuing agency system 200 at the stage of S80. The issuing

agency system 200 provides the web page for settlement to the client system 300

of the requester through the web server 210 and the requester requests the

settlement of the certificate to be issued by inputting the information related to the

settlement on the web page for settlement and transmitting the information to the

issuing agency system 200.

As a method for settlement through the web page for settlement, various

methods for settlement known to those skilled in this art may be used. For

example, methods for settlement by credit card, cyber money, depositing without

bankbook within a fixed period of time, phone number of mobile communication

terminal(a method that the cost for the certificate settlement is charged together

with the rate for using mobile communication terminal), etc may be mentioned.

Accordingly, the web page for settlement preferably comprises a web interface

allowing the requester personally to choose the method for settlement. The

information required for settlement of the predetermined certificate issuing cost

according to each settlement method is already known to those skilled in the art,

so the detailed description is omitted. When the requester provides the kind of the settlement method and the

information required for the settlement according to the chosen settlement method

to the issuing agency system 200 through the web page for settlement at the

stage of S80, the issuing agency system 200 checks, at the stage of S90, if the

settlement according to the chosen settlement method is possible at that time

when the settlement is requested. For example, in case that the requester

chooses the settlement by credit card, the issuing agency system 200 checks if

the settlement for the cost of the certificate to be issued, i.e. the admission ticket

for movie by credit card is available through the payment gateway. The issuing

agency system 200 performs operation for settlement when the settlement for the

same by credit card is verified to be available and provides an error message that

the settlement is not possible to make to the client system 300 of the requester at

the stage of S95 when not available.

When the settlement for the admission ticket for movie is successfully

made at the stage of S90, the issuing agency system 200 provides a web page

including a certificate receiver information input interface allowing inputting the

phone number of the receiver's mobile communication terminal 330 at the stage

of S100. At this moment, the receiver may be the requester him/herself or another

person whose phone number of mobile communication terminal 330 is known to

the requester. The requester inputs the information related to the certificate

receiver such as phone number of mobile communication terminal 330, name,

gender, etc. on the web page for inputting the information of the certificate

receiver and provides the information to the issuing agency system 200 through the internet. Then, the issuing agency system 200 stores the information that the

requester provides to receive the admission ticket for movie in a corresponding

information storage section in the first database at the stage of S1 10. More

precisely, the issuing agency system 200 stores the information related to the

admission ticket for movie, i.e. name of movie theater, number or name of

screening hall, title of the movie to see, screening date, screening time, number of

tickets, and the phone number of mobile communication terminal 330 of the

receiver matched with the member information of the requester(for example,

member ID) in the certificate bar-code issuing particulars information storage

section in the first database 252. At the same time, the issuing agency system 200

issues the authentication key to certify the certificate bar-code when the certificate

bar-code is used after issuing the same and stores the authentication key in the

certificate bar-code authentication key information storage section in the second

database 262 synchronized with the certificate server 260.

Next, the issuing agency system 200 enciphers, at the stage of S120, the

information related to the certificate to be issued, i.e. the admission ticket for

movie(for example, name of movie theater, number or name of screening hall, title

of the movie to see, screening date, screening time, and number of tickets) and

the authentication key by using an encryption algorithm, for example, the Hash

algorithm. Then, the enciphered information is transformed into a bar code by

using a bar code technique well known to those skilled in the art, for example, a

PDF417 2D bar code technique. When the amount of information of the certificate

to be issued is a lot as in case of the admission ticket for movie, it is preferable to use a two-dimensional bar-code instead of a one-dimensional one.

Fig. 7 is a diagram for exemplifying various bar-code which may be used

by mobile communication terminal of the present invention. In order from left

upper portion to lower portion, Code Block, Code 49, Code 16, and QR Code are

shown and in order from right upper portion to lower portion, Maxi Code, Data

Matrix, and PDF-417 are shown in Fig. 7. There is no wonder for those skilled in

the art that what type of bar-code among those shown in Fig. 7 is used for the

certificate bar-code circulating method according to the present invention is not

important.

Then, the issuing agency system 200 transmits, at the stage of S130, the

data transformed into the bar-code to the mobile communication business

proprietor system 320 and the mobile communication business proprietor system

320 transmits the certificate bar-code data to the mobile communication terminal

330 of the receiver of the certificate through the wireless communication network.

At this moment, it is preferable to transmit a simple text data providing the

information about bar-code(for example, the information about the kind of the

certificate bar-code) together with the bar-code data. Since such transmission of

data can be made by a similar method to that of a text message service provided

by the mobile communication business proprietor at the present time, a

cooperating system between the mobile communication business proprietor and

the issuing agency should be made in advance to provide such services.

Next, the issuing agency system 200 transmits, at the stage of S140, the bar-code issuing particulars(the information including the information registered at

the bar-code for the admission ticket for movie and the authentication key) to the

client system 310 of the corresponding distributor for the corresponding distributor

to easily verify if the bar-code for the admission ticket for movie presented by the

receiver is properly paid and issued. Then, the client system 310 of the distributor

registers the information transmitted from the issuing agency system 200 at the

certificate bar-code issuing particulars information storage section in the database

312 of its own and uses the same information for the authentication of the

corresponding certificate bar-code when the receiver uses the certificate bar-code.

Finally, the issuing agency system 200 transmits, at the stage of S150, a notice

text message(for example, 'The certificate bar-code is issued. Please use the

same in the fixed period of time!') more than one time at least through the mobile

communication business proprietor for the receiver to use the certificate bar-code

in time.

Fig. 4 is a structural diagram of module of program for processing the bar¬

code installed in the mobile communication terminal according to the present

invention.

Referring to Fig.4, the program for processing the bar-code preferably

comprises a first module 340 for informing the receiver of the receipt of the

certificate bar-code image data by a graphic interface and storing the received

data in the memory 90 when the certificate bar-code image data issued by the

issuing agency system 200 is received; a second module 350 for outputting the

information of the kind of the certificate bar-code stored in the memory 90 listed in a predetermined order(for example, in received order) to the displaying portion 50

of the mobile communication terminal I when the receiver requests the

information; a third module 360 for extracting detailed information related to the

certificate registered in the bar-code image data by decoding the bar-code image

data stored in the memory 90 and displaying a predetermined format of extracted

information on the displaying portion 50 of the mobile communication terminal I in

response to the request of the receiver; a forth module 370 for deleting a

certificate bar-code data stored in the memory 90 in response to the request of the

receiver; a fifth module 380 for displaying a predetermined certificate bar-code

data stored in the memory 90 on the displaying portion 50 of the mobile

communication terminal I through a graphic interface in response to the request of

the receiver; a sixth module 390 for transforming the text type information to be

registered in the certificate bar-code transmitted from the issuing agency system

200 to the mobile communication terminal I into a bar-code by using an encryption

algorithm such as PDF 417 encryption algorithm and outputting the bar-code

image on the displaying portion 50; and a seventh module 400 for deciphering the

information registered in the bar-code scanned by the camera 100 comprised in

the mobile communication terminal I by a decipherment algorithm such as PDF

417 decipherment algorithm.

Fig. 5 is a flow chart showing a procedure of processing the certificate

bar-code in the mobile communication terminal I belonging to the receiver

according to the certificate bar-code circulating method by mobile communication

terminal of the present invention. Referring to Fig. 5, at the stage of F10, the receiver of the certificate

transmits the instruction of executing the bar-code processing program stored in

the memory 90 to the central processing unit 30 through the key pad portion

comprised in his/her mobile communication terminal 330. Then, the central

processing unit 30 operates the bar-code processing program stored in the

memory 90 and provides a 'bar-code selecting menu' for selecting the certificate

bar-code stored in the displaying portion 50 of the mobile communication terminal

330 at the stage of F20. Next, when the receiver selects a 'bar-code selecting

menu' through the key pad portion 40, the central processing unit 30 lists the bar-

code information(for example, the information of the kind of the certificate bar¬

code) stored in the memory 90 in a predetermined order and provides the same to

the receiver by the second module at the stage of F30. The receiver of the

certificate selects the certificate bar-code that he/she wants to verify from the list

of the certificate bar-code and requests the central processing unit 30 to provide

the detailed information of the selected certificate bar-code at the stage of F40.

The central processing unit 30 displays, at the stage of F50, the detailed

information of the selected certificate bar-code on the displaying portion 50 of the

mobile communication terminal 330by using the third module. Here, the detailed

information of the certificate bar-code is preferably the information related to the

certificate issuing registered in the certificate bar-code. For example, when the

certificate bar-code selected by the receiver is an admission ticket for movie, the

detailed information of the certificate bar-code may be name of movie theater,

number or name of screening hall, title of movie, screening date, screening time, and number of ticket, but not limited to the same. When the detailed information of

the certificate bar-code is output, a 'bar-code image view menu' for displaying the

bar-code image on a predetermined area of the displaying portion 50 is output.

When the receiver selects the bar-code image view menu, the central processing

unit 30 displays, at the stage of F60, the selected certificate bar-code in the form

of image on the displaying portion 50 of the mobile communication terminal 330 by

using the fifth module. When the function outputting the detailed information of the

certificate bar-code through the displaying portion 50 of the mobile communication

terminal 330 is embodied, the same may be embodied by the central processing

unit's 30 using the third module or by the issuing agency system's 200

transmitting the detailed information of the certificate bar-code in the form of text

together with the bar-code image data to the mobile communication terminal 330.

In addition, there is no wonder for those skilled in the art that the bar-code

processing program may provide a menu navigation allowing deleting the

certificate bar-code data stored in the memory 90 in response to the receiver's

request input through the key pad portion 40.

Fig. 6 is a flow chart showing a procedure of processing the certificate

mobile communication terminal of the present invention.

Referring to Fig. 6, the receiver of the certificate operates the bar-code

processing program by using the key pad portion 40 of the mobile communication

terminal, selects the certificate bar-code he/she wants to use at that time among

received ones, and displays the certificate bar-code image on the displaying portion 50 of the mobile communication terminal 330 at the stage of G10. Next, at

the stage of G20, in the distributor, the certificate bar-code image output on the

receiver's mobile communication terminal 330 is scanned by the bar-code

scanner 314 synchronized with the client system 310 of the distributor to input the

bar-code image into the client system 310 of the distributor. Then, the bar-code

decoding module operating in the client system 310 of the distributor extracts the

information related to the certificate issuing and authentication key registered in

the bar-code by decoding the scanned certificate bar-code. The client system 310

of the distributor certifies, at the stage of G30, the certificate bar-code scanned at

that moment by searching the certificate bar-code issuing particulars information

storage section stored in the database of its own by using the information related

to the certificate issuing and the authentication key.

When the certificate bar-code scanned at that moment is certified as one

properly issued by the issuing agency system 200 at G30, the client system 310 of

the distributor registers, at the stage of G40, the fact that the certificate is used in

the using particulars information storage section of the database of its own and

provides, at the stage of G50, an admission ticket for movie as the detailed

information scanned to the receiver of the certificate.

However, when the certificate bar-code scanned at that moment is

certified as not properly issued one at G30, the client system 310 of the distributor

requests, at the stage of G60, the authentication by transmitting the information

about the scanned certificate bar-code(for example, the extracted authentication

key) to the issuing agency system 200 and waits for the authentication of the above-mentioned certificate bar-code from the issuing agency system 200. Then,

the certificate server 260 of the issuing agency system 200 performs an

authentication process to the certificate bar-code requested to be certified by

searching the authentication key information storage section in the second

database 262 by using the certificate bar-code information(for example, the

extracted authentication key) transmitted at the stage of G60. When the certificate

bar-code requested to be certified is properly issued by the issuing agency system

200 is certified and the authentication admission code is transmitted to the client

system 310 . of the distributor, the client system 310 stores the admission

particulars information in the database 312 of its own and provides a actual

admission ticket for movie according to the certificate bar-code at the stage of G80.

On the contrary, when the admission for the certificate bar-code requested to be

certified is not made at the stage of G70, the client system 310 notifies the

receiver of the certificate that the certificate bar-code cannot be used at the stage

of G90.

So far the preferred embodiment of the certificate bar-code circulating

method by the mobile communication terminal according to the present invention

is described in detail. As shown in Figs. 3 to 6 and detailed description of the

present invention referred to the same, the preferred embodiment of the present

invention described above is about a case that when the issuing agency system

200 transforms the certificate to be issued into a bar-code image and transmits the

certificate bar-code image to the mobile communication terminal 330 of the

receiver of the certificate, the receiver uses the transmitted certificate bar-code image, which is stored in the memory 90 of the mobile communication terminal

330, at the distributor.

However, in some case, the issuing agency system 200 may not transmit

the certificate bar-code of itself formed at the stage of S120 to the receiver's

mobile communication terminal 330, but transmit the information of kind of the

certificate bar-code only to the mobile communication terminal 330 after

registering the formed certificate bar-code in the first database 252 by receivers.

In this case, the precise description of the procedure that the receiver of the

certificate uses the certificate bar-code at a distributor is as follows.

<Case 1 : In case that the requester of the certificate bar-code and the

receiver of the certificate are the same person, or although different, the receiver

of the certificate is already registered in the issuing agency system 200>

First, the receiver of the certificate visits the off-line distributor and

accesses the issuing agency system 200 through a member log-in by using the

mobile communication terminal 330. In this case, the WAP server 280 of the

issuing agency system 200 should form a network interface between the issuing

agency system 200 and the receiver's mobile communication terminal 330. Next,

the receiver of the certificate requests a WAP interface allowing calling the

certificate bar-code issued for him/her from the issuing agency system 200 and

the issuing agency system 200 provides a WAP interface allowing calling the

receiver's certificate bar-code in the database to the receiver's mobile

communication terminal 330. The receiver may receive the certificate bar-code in

graphic interface through the displaying portion 50 of the mobile communication terminal 330 by calling a certificate bar-code he/she wants to use at that time

among certificate bar-codes issued for him/her from the first database 252 of the

issuing agency system 200 by the WAP interface. Then, the receiver presents the

certificate bar-code in graphic interface displayed on the displaying portion 50 of

the mobile communication terminal 330 and the client system 310 of the distributor

treats the certificate bar-code according to the practically same procedure as that

from G20 to G90 in Fig. 6.

<Case 2: In case that the requester of the certificate bar-code and the

receiver of the certificate are different and the receiver of the certificate is not

registered in the issuing agency system 200>

In this case, the receiver may call the certificate bar-code on the

displaying portion 50 of the mobile communication terminal and use the same

through the practically same procedure as that of the case 1 except that the

receiver should go through the stages of member registration and member

certification when he/she accesses the issuing agency system 200 through the

wireless network by the mobile communication terminal 330. The client system

310 of the distributor treats the certificate bar-code according to the practically

same procedure as that from G20 to G90 in Fig. 6.

The above-described certificate bar-code circulating method by the mobile

communication terminal according to the present invention is not restricted to the

above-mentioned embodiment, but variously modified within the scope of the art.

For example, the bar-code forming module and the decoding module in the mobile

communication terminal I may be embodied as a hardware module. Plus, contrary to the above-described embodiment, it may also be

possible that the issuing agency transmits text data only to be registered in the

bar-code and the mobile communication business proprietor transforms the same

into bar-code. In this case, the peculiar number of the receiver's mobile

communication terminal 330 that the mobile communication business proprietor

knows may be further included in the information to be transformed into bar-code.

Then, it is more difficult to improperly issue or duplicate the certificate bar-code.

Further, it may also possible that the certificate issuing particulars in the form of

text is transmitted to the receiver's mobile communication terminal 330 and

transformed into the bar-code in the receiver's mobile communication terminal

330. Further, the issuing agency and the mobile communication business

proprietor may be the same.

Finally, according to the characteristics of the certificate, it may also be

possible that the issuing agency does not provide any information to the distributor

at the time of issuance and the distributor accesses the issuing agency and

receives the authentication of the certificate bar-code at the time that the

distributor treats the certificate bar-code in the receiver's mobile communication

terminal 330.

According to an aspect of the present invention for users, since the

certificate bar-code is wirelessly received through the mobile communication

terminal widely used and always carried, there is no time and space limit and

there is no need to carry another certificate.

According to another aspect of the present invention for distributors, the manpower required for verifying if the certificate is true or fake and for inputting

and managing data may be reduced.

While the present invention has been described in detail with reference to

the preferred embodiments, those skilled in the art will appreciate that various

modifications and substitutions can be made thereto without departing from the

spirit and scope of the present invention as set forth in the appended claims.
