However, since it is clear that the embodiments of the present invention can be implemented through various changes or modifications within the scope of the present invention, it is not limited to the described embodiments. In addition, the embodiments of the present invention will not be described in detail because those of ordinary skill in the art can add and implement well-known components, functions, methods, and typical details.

Referring to FIG. 1, the electronic business card service system according to an embodiment of the present invention includes a business card registration unit 110, a business card service unit 120, a public information providing unit 130, and a contact relay unit 140, and a network The coded business card 1 that can access the business card information is delivered to the smart device 200 of the user who accesses it through 300 and registers business card information and creates a user account, so that the coded business card 1 is exchanged between users. and provides an electronic business card service to a smart device 200 connected to another person's coded business card 1.

Here, the coded business card 1 may be, for example, a QR code or barcode, as is known in the art related to electronic business card services.

The network 300 may include an Internet network and may include a WiFi network capable of accessing the Internet network.

After accessing the system, the smart device 200 inputs and registers business card information, stores the coded business card 1 delivered from the system, and tags another person's coded business card 1 to obtain the smart device 200 Smartphones, tablet PCs, PCs, etc. that can be exchanged between users, store another person's coded business card (1) received through the exchange, and then read the information recorded on the coded business card (1) to access this electronic business card service system. , and a business card app 210 capable of easily performing these functions and using an address book to store other people's codes and business cards may be installed.

According to an embodiment of the present invention, since a voice call is transmitted as a VoIP packet using the Internet network according to mVoIP (mobile voice over Internet Protocol) technology, the business card app 210 implements an Internet phone service function.

As such, the technology for installing and using the application for the above function in the smart device 200 is known in the prior art in various ways in the technical fields related to electronic business card services and mVoIP services, and detailed descriptions thereof are omitted.

However, in the embodiment of the present invention, the coded business card is different from the prior art in that an access code for accessing business card information and a one-time authentication code added whenever a coded business card is exchanged are recorded, as will be described later. Accordingly, since the coded business cards delivered to others for exchange between users are newly issued with different one-time authentication codes recorded, different coded business cards are delivered to each other. That is, a coded business card exchanged between users is newly issued by this system and delivered to the user's smart device 200 .

1 for the business card registration unit 110, the business card service unit 120, the public information providing unit 130, and the contact relay unit 140 constituting the electronic business card service system 100 according to an embodiment of the present invention. And with reference to Figure 2 will be described in detail.

2 is a flowchart of an electronic business card service method executed with the configuration of the electronic business card service system according to the embodiment of the present invention shown in FIG.

As shown in FIG. 2, a user accessing the business card service unit 120 with another person's coded business card 1 is set as a first user, and the coded business card 1 used for access is an electronic business card service system. An embodiment in which the user generated and transmitted in step 100 is the second user will be described. However, this embodiment is an exemplary embodiment, and it is obvious that three or more users can use the electronic business card service.

The business card registration unit 110 is for performing a process of registering business card information of a plurality of users (S10, S11, S20, S21).

That is, the user who wants to receive the electronic business card service installs the business card app 210 having the above-mentioned functions on the smart device 200, runs the business card app 210 to access the business card register 110, and then , create a user account and register business card information.

At this time, each user can create a user account by registering the user's ID, password, and phone number of the smart devices 200-1 and 200-2 used for access.

Thereafter, the user may register business card information including a user name, contact method, and public information (S10 and S20).

Referring to FIG. 3, in order to register business card information, the UI screen 10 provided to smart devices 200-1 and 200-2 to input business card information includes UI controls 11, 12, and 12 for each item of business card information. 13, 14, 15, 16) is provided, and it is possible to register in the electronic business card service system 100 by inputting business card information using the UI control.

The UI control (11, 12, 13, 14, 15, 16) for registering business card information includes a text field (11) to input a 'user name' to be used for identification, and a plurality of 'contact methods' to be selected. It includes a check box 12 that can be used, a text field 15 for inputting public information among business card information, and a check box 16 for selection.

The 'user name' can be registered by entering the user name in the text field 11.

Although it is disclosed in advance, in the present invention, since contact can be made even though the contact information is not disclosed, the 'user name' is used to confirm the identity of the other party when contacting users. Here, the contact is a phone number in case of voice call, a phone number in case of 'SNS', and an e-mail address in case of e-mail, but in the present invention, it is made private and can be contacted.

The 'contact method' includes 'Cellphone' of a voice call method, 'SNS' of a social network service method, and 'e-mail' of an e-mail (e-mail) method, and each check box 12 You can select and enter by checking.

However, when 'e-mail' is checked, a radio button 13 is provided to select between 'new e-mail' using the mail server of the present invention and 'existing e-mail' used by the user. and, in the case of selecting 'existing e-mail', the user's e-mail address was entered in the text field 14.

Here, text fields for inputting contact information for 'Cellphone', 'SNS' and 'new e-mail' are not provided. This, as will be described later, enables contact only through the electronic business card service according to the present invention with a corresponding contact method, and makes it impossible to inform contact information when contacting.

As will be described later, the user's e-mail address entered when 'existing e-mail' is selected is not disclosed even if the user's e-mail address is registered because the user's e-mail address is not disclosed and the e-mail is relayed.

'Public information' is information disclosed when the user's electronic business card is shown to others, and as illustrated in FIG. 'Hobby', where information related to hobbies (including videos or photos) can be registered as 'My blog', a personal posting space, 'Specialty', where information of personal interest can be registered, 'My Location' and 'My Album', which can register photos taken by the user, are provided so that the check box 16 of the desired item can be checked. Here, a detailed description of a selected item among a plurality of items of the personal blog will be omitted, but an interface for uploading information of the corresponding item is provided.

In this way, when the user inputs business card information, the business card registration unit 110 stores it in a database (not shown) for each user account.

In addition, the business card registration unit 110 transmits the coded business card 1 on which the access code and authentication code are recorded to the user who has registered the business card information to the user's smart device 200-1, 200-2 (S11, S21).

Here, the access code includes the following URL address of the business card service unit 120 and the address (or database address) of business card information stored in the database, allowing access to business card information.

The authentication code is generated as a random code as a one-time code for giving permission to use only the other person who has received the coded business card 1 directly.

In this way, the coded business card 1 delivered to the user's smart device 200-1 or 200-2 is stored in the user's smart device 200-1 or 200-2 and can be exchanged between users (S30). .

At this time, the coded business card exchange is performed by displaying the coded business cards stored in the smart devices 200-1 and 200-2 on the screen and then tagging them with the other smart devices 200-1 and 200-2, so that the other smart device ( In 200-1 and 200-2), information recorded on the coded business card may be read or the coded business card may be photographed and stored.

In addition, the business card registration unit 110 operates in conjunction with the user's smart device 200 that exchanges the user's coded business card with another person, and when exchanging the user's coded business card, a new coded business card randomly generated with an authentication code. By generating and delivering to the user smart device 200, the coded business card stored in the user smart device 200 is replaced with a coded business card having a changed authentication code.

That is, coded business cards exchanged between users using the user smart device 200 become coded business cards on which different authentication codes are recorded each time they are exchanged.

To this end, the authentication code is randomly generated without duplication for the same access code, so that one-off can be more reliably guaranteed as a code of shorter length. That is, each time a coded business card is exchanged, a coded business card with a different authentication code is used.

In addition, the business card registration unit 110 transmits an authentication code generated for each user and recorded on a coded business card to the business card service unit 120 so that it is matched and stored in a user account. This is to authenticate access according to an authentication code as will be described later.

As a modified embodiment for changing the authentication code of the coded business card to be exchanged, immediately before exchanging the coded business card in the user's smart device 200, the authentication code is randomly regenerated and the recorded coded business card is stored on the user's smart device 200. may be conveyed.

On the other hand, the business card registration unit 110 allows to log in with a user account and update business card information.

The business card service unit 120 exchanges the coded business card 1 delivered to the user's smart device 200-1, 200-2 between users and receives the coded business card 1 of another user's smart device 200-1 accesses to another person's coded business card (1) and receives the electronic business card service.

As shown in the flowchart of FIG. 2, among the first user and the second user who exchanged coded business cards, the smart device 200-1 of the first user reads the stored coded business card of the second user and accesses the coded business card. When accessing the business card service unit 120 having the URL address of the code and trying to receive the electronic business card service of the business card information storage address of the access code of the coded business card (S40), the business card service unit 120 An access authentication process (S41) is preceded according to the authentication code.

The business card service unit 120 stores and manages the one-time authentication code generated by the business card registration unit 110 for each user account in order to perform the access authentication process (S41), and the user corresponding to the storage address of the access code of the coded business card. Access is authenticated only when access is made with a coded business card that has a one-time authentication code stored and managed in the account.

The business card service unit 120 sends an electronic business card by using the coded business card only to the smart device 200-1 of the first user, which is the party directly receiving the coded business card of the second user from the smart device 200-2 of the second user. In order to receive the service, only the user who initially accesses using the coded business card can repeatedly access the same coded business card.

To this end, the business card service unit 120 performs access authentication using the authentication code only once for each authentication code when accessing a coded business card having the same access code and different authentication codes.

That is, the business card service unit 120 records the access authentication history using the authentication code or the authentication code used during access authentication as access authentication history information, and instead, the first user smart device 200 that authenticated the access The device information of -1) is received and stored from the first smart device 200-2, and then, when accessing with an access code having an access authentication history of the authentication code, the first user having the previously stored device information Access authentication is performed only for the connection of the smart device 200 .

Accordingly, the first user smart device 200-1 can be repeatedly authenticated for access with the coded business card of the second user, so that the following business card page can be provided each time access is made. However, even if the third user's smart device acquired without directly receiving the second user's coded business card accesses the second user's coded business card, the first user's smart device 200-1 accesses it and has an authentication history of the authentication code. , access authentication cannot be obtained, and the following business card page cannot be provided.

As a modified embodiment, the business card service unit 120 stores the device information of the first smart device 200-1 that has authenticated access, deletes the authentication code used for authentication from the storage record, and converts it to an access code. The process of authenticating access with the device information of the first smart device 200 to be connected may be performed prior to the process of authenticating access using an authentication code. That is, if access is authenticated with device information, an access authentication process using an authentication code is unnecessary and can be omitted. However, when access is not authenticated with device information, access is authenticated with an authentication code. At this time, when a third user smart device accesses, the authentication code is deleted from the record, so access authentication cannot be obtained.

4 is a configuration diagram of a UI screen output according to a business card page delivered to a user's smart device.

The business card service unit 120 transmits the business card page for configuring the UI screen 20 illustrated in FIG. 4 to the first user smart device 200-1 that has been authenticated for access with the coded business card as described above (S42 ).

The business card page delivered to the first user smart device 200-1 includes the user name 21 of the user account corresponding to the access address of the coded business card and UI controls for each item of business card information (22, 23, 24, 25, 26), and as illustrated in FIG. 4, the user name 21 and the UI controls 22, 23, 24, 25, 26 for each item of business card information are displayed on the UI screen 20 as the first display. It is output to the user smart device 200-1.

Referring to FIG. 4, on the UI screen 20 based on the business card page, as described with reference to FIG. 3, business card information registered by the user is not exposed and output, but UI controls 22 generated for each item of business card information. , 23, 24, 25, 26).

That is, business card information is not shown on the business card page that is accessed and displayed through the coded business card (1), and UI controls (23, 24, 25) of 'Cellphone', 'E-mail' and 'SNS', which are items of contact method, , By tapping the UI controls (22, 26) of 'Company', 'Department', 'Hobby', 'Specialty', 'My location' and 'My Album', which are items of public information, the business card information of the item of the UI control tapped can access Exceptionally, the photo (27) of the item is displayed under the UI control (26) of the 'My Album' item, which is one of the public information, but to view the business card information of the 'My Album' item, tap the UI control (26). shall.

The public information providing unit 130 is a public information item among the UI controls 22, 23, 24, 25, 26 on the UI screen 20 output to the first user smart device 200-1 by the business card page. When the user taps and selects the UI controls 22 and 26 (S50), public information corresponding to the selected UI control is transmitted to the smart device 200-1 of the first user and outputted (S51).

The contact relay unit 140 is a UI control with a contact method as an item among the UI controls 22, 23, 24, 25, and 26 on the UI screen 20 output to the first user smart device 200-1 ( 23, 24, 25) is selected by the user (S60), between the first user smart device 200-1 and the second user smart device 200-2 in a contact method corresponding to the selected UI control. Relay conversations by establishing a session to keep contacts private.

For session establishment, it is natural that a procedure of logging in with a user account or a procedure of automatically logging in according to the phone numbers of the user smart devices 200-1 and 200-2 precedes.

As an embodiment, the contact relay unit 140 relays between the first user smart device 200-1 and the second user smart device 200-2, so that the first user and the second user are contact parties. In order to verify the identity of the other party, the user name of the user account may be transmitted to the other party, but not the contact information, and only conversation contents may be relayed.

As an embodiment, the contact relay unit 140 establishes a first session for conversation with the first user smart device 200-1, and establishes a second session for conversation with the second user smart device 200-2. After establishing a session, a link for conversation transfer between the first session and the second session is established, and contacts are made private and between the first user smart device 200-1 and the second user smart device 200-2. conversations can be relayed.

At this time, the contact relay unit 140 connects the first user smart device 200-1 and the second user smart device 200-2 through an Internet network, respectively, and the first user smart device 200-1 and the second user smart device 200-1. The two-user smart device 200-2 can be identified by its IP address to establish a session, and it can relay a conversation by identifying it with its IP address. Here, a session for direct connection between the first user smart device 200-1 and the second user smart device 200-2 is established, and the counterpart is identified by an IP address, and the user name of the first user and the second user You can also have your username confirm the identity of the other party.

According to a specific embodiment of the present invention, since 'Cellphone', 'SNS', and 'E-mail' can be selected as the contact method as illustrated in FIG. 3, the VoIP server 141 for 'Cellphone', 'SNS' It includes an SNS server 142 for and a mail server 143 for 'E-mail'.

When the UI control 23 expressed as 'Cellphone' is selected by the first user, the VoIP server 141 establishes a session for transmitting and receiving voice packets with the first user's smart device 200-1. , the mVoIP call is requested to the second user smart device 200-2 with the phone number of the second user account, and the user name of the first user is transmitted to confirm the identity.

And, the VoIP server 141 establishes a session for transmitting and receiving voice packets with the second user smart device 200-2 when the second user smart device 200-2 responds to the mVoIP call request, and then , By linking both sessions for transmission of voice packets, a session for relaying voice packets is established between the first user smart device 200-1 and the second smart device 200-2, and the call can be relayed. .

Here, the first user smart device 200-1 and the second smart device 200-2 are identified by the IP address at the time of session establishment, and the session ID is used to link between the first user and the second user. You can relay calls while keeping your phone number private.

The SNS server 142 establishes a session for sending and receiving messages with the first user smart device 200-1 when the UI control 25 expressed as 'SNS' is selected by the first user, SNS communication is requested to the second user smart device 200-2 with the phone number of the second user account, and the user name of the first user is transmitted to confirm the identity.

And, the SNS server 142 establishes a session for message transmission and reception with the second user smart device 200-2 when the second user smart device 200-2 responds to the SNS communication request, and then, By linking both sessions for message delivery, a session for relaying a message may be established between the first user smart device 200-1 and the second smart device 200-2 to relay the message.

Here, too, the first user smart device 200-1 and the second smart device 200-2 are identified by their IP addresses at the time of session establishment, and the session ID is used to link between the first user and the second user. You can relay calls while keeping your phone number private.

The mail server 143 can be configured to transmit email in three ways when the UI control 24 expressed as 'E-mail' is selected in the first user smart device 200-1.

First, when the first user and the second user select 'new E-mail' when registering business card information, mail using the mail server 143 as a host is used.

In this case, the mail server 143 establishes a session for writing mail with the first user smart device 200-1 requesting contact, and displays a screen of the first user smart device 200-1 for writing mail. The UI screen is output, and the written mail is received and stored in association with the second user account.

In addition, the mail server 143 sends a push notification to the second user smart device 200-2 identified by the second user's phone number to inform the second user that there is a received mail, and the second user smart device ( In 200-2), when logging in with the second user account, the e-mail can be opened.

Here, the mail server 143 can automatically identify the mail recipient as the second user by the coded business card 1 used when the first user smart device 200-1 accesses, and the second user also has an account. Since e-mail is received through the e-mail address, the e-mail can be relayed without generating the e-mail addresses of the first user and the second user.

In addition, the sender of the mail uses a user name registered in the first user account, so that the second user who is the recipient can verify the identity of the sender.

Second, when registering business card information, the first user selects 'new E-mail' to use the mail server 143 as a host, and the second user selects 'old E-mail' when registering business card information. This is the case when an e-mail address is registered by selecting '-mail'.

This case will be described with reference to the flowchart of FIG. 5 .

The mail server 143 establishes a session for writing mail with the first user smart device 200-1 requesting contact, and outputs a UI screen for mail writing on the screen of the first user smart device 200-1. and receive the written mail (S70).

In addition, the mail server 143 uses the email address registered in the second user account as the recipient's email address, the sender's email address as a one-time transmission email address, and uses the sender's name to verify the identity of the sender. , mail is transmitted (S71). Accordingly, the transmitted mail is delivered to the second user mail server 410, which is the host server of the email address registered in the second user account, so that the second user can view it (S72).

Here, the sending e-mail address is a one-time address composed of a web address with the mail server 143 as a host, and may be determined in advance by combining an arbitrary user ID with the web address for transmission.

Even in this case, it is possible to send mail while keeping the mail addresses of the first user and the second user private.

Third, when the first user and the second user select 'existing e-mail' when registering business card information and register e-mail addresses.

This case will be described with reference to FIG. 6 .

The mail server 143 transfers the one-time reception email address to the first user smart device 200-1 (S80).

The first user uses a mail app installed on the first user smart device 200-1, that is, a mail app that allows the user to use the mail service through the first user mail server 420, which is the host server of the email address registered in the user account. Using this, it is possible to create and send an e-mail in which the one-time receiving e-mail address is entered in the recipient's address (S81). Accordingly, the sent mail is transmitted to the mail server 143 (S82).

The mail server 143 transmits the mail in which the one-time transmission e-mail address is entered as the sender's e-mail address and the e-mail address of the second user registered in the second user account is entered as the recipient's e-mail address (S83). Accordingly, the second user can read the mail through the second user mail server 410, which is the host server of the second user's e-mail address registered in the second user account (S84). Of course, the mail transmitted from the mail server 143 includes the contents of the mail transmitted from the second user mail server 420, and the user name of the first user may be entered to verify the identity of the sender, the first user. there is.

Here, the receiving e-mail address, like the sending e-mail address, is a one-time address composed of a web address hosted by the mail server 143, and is assumed to be determined by combining a random user ID with a web address in order to receive an e-mail. can

In addition, the received e-mail address transmitted to the first user smart device is recorded in association with the first user e-mail address, so that only mail sent to the recorded user e-mail address and the received e-mail address is selectively received and relayed. That is, if the mail is not sent to the recorded user's e-mail address and the receiving e-mail address, the reception is rejected. Accordingly, after accessing the coded business card, only the first user to whom the receiving e-mail address is delivered can use the receiving e-mail address.

Even in this case, it is possible to send mail while keeping the mail addresses of the first user and the second user private. Accordingly, while using the user's e-mail address, it is possible to use the mail service while keeping the user's e-mail address private.

Although the above has been shown and described as specific embodiments to illustrate the technical idea of the present invention, the present invention is not limited to the same configuration and operation as the specific embodiments as described above, and various modifications are within the scope of the present invention. can be carried out in Accordingly, such modifications should be regarded as belonging to the scope of the present invention, and the scope of the present invention should be determined by the claims described below.
