1 is a configuration diagram of a digital business card providing system according to an embodiment.

Referring to FIG. 1 , a digital business card providing system may include an application system 100 that provides a digital business card service, and terminals 200 and 210 that install applications and interoperate with the application system 100 . The terminal 200/210 creates and shares digital business cards through applications, stores or shares other people's digital business cards in a user account box, and provides a digital business card-based chat service. In the description, it is assumed that the terminal 200 creates a digital business card and the terminal 210 receives another person's digital business card. Here, the storage box of the user account exists in the application system 100, and the terminal may display business cards stored in the storage box of the user account through an application executed by the user account. In some cases, a terminal on which an application is installed may store business cards in a locally assigned user account storage box. For convenience of explanation, it is explained that the business card is stored in the storage box of the user account, but the storage box of each user account stores the business card identifier, and the stored business card can be called through the identifier.

Applications include commands and data for functions necessary for digital business card service, and application types may vary according to digital business card service methods. For example, a digital business card service may be provided in a dedicated application, or a messaging application providing a messaging service. Meanwhile, the application may include all functions required for a digital business card service, but may provide the digital business card service described in the present disclosure through interworking with other applications (eg, messaging applications). In addition to the application system 100, the application may provide a digital business card service through interworking with other servers. Therefore, for convenience of explanation and functional description, even if the application is described as including a business card module, an authentication module, a messaging module, and a channel service module providing a channel service, an application providing a digital business card service is necessarily composed of these modules. It does not need to be classified or distinguished, and the design can be changed in various ways according to the digital business card service method or the characteristics of the software. In addition, although the application is described as interworking with the application system 100, it is not necessary to interwork only with the application system 100.

In the following, instead of ‘digital business card’, we can simply call it ‘business card’. In addition, 'digital business card' can be called 'talk business card' in the sense provided by the KakaoTalk application.

The application system 100 includes a digital business card server 110 for creating and managing digital business cards, an authentication server 130 for performing identity authentication and qualification/identity authentication of a card creator, a messaging server 150 for providing messaging services, And it may include a channel service server 170 providing a channel service. In the description, entitlement/status is used in the sense of entitlement and status, or including entitlement or status.

For convenience of description and description of functions, the application system 100 is divided into a digital business card server 110, an authentication server 130, a messaging server 150, and a channel service server 170, but the digital business card service The provided application system does not necessarily need to be configured or divided into these servers, and can be variously changed according to the digital business card service method or server design. That is, the application system 100 can provide all the functions necessary for the digital business card service, but can provide the digital business card service in conjunction with other servers that provide the necessary functions.

First, the authentication server 130 provides various authentication services related to digital business cards. The authentication server 130 may perform personal authentication, qualification/identity authentication, and the like of a card creator in conjunction with the digital business card server 110 . The authentication service may include a certificate-based wallet service provided by the KakaoTalk application.

When the identity authentication account is entitled to create a business card, the authentication server 130 may proceed with a identity authentication procedure before creating a business card.

Alternatively, when the authentication server 130 issues a certificate to a user of an application account, a user authentication procedure may be provided so that a digital business card is generated through user authentication through a certificate.

The authentication server 130 may authenticate the user's qualification/identity and manage the digital ID assigned to the qualification/identity. Qualification is a qualification issued by an institution that the authentication server 130 interworks with, and may include national qualification as well as private qualification. The identity may be an identity belonging to an organization or a company with which the authentication server 130 interoperates. The authentication server 130 may provide the user's qualification/identity list to the digital business card server 110 and provide the digital business card server 110 with whether each qualification/identity written in the business card has expired. The digital business card server 110 may interwork with the authentication server 130 to periodically check whether qualification/identity has changed, and update the business card based on the qualification/identity change information. Whether or not to change will be determined depending on whether the period for the qualification/status with the validity period has expired, whether the validity period for the qualification/status with the validity period has been extended, whether there is a change in status such as withdrawal/resignation, change in position/position, change in affiliation, etc. can Through this, the created and shared business card can display the currently valid qualification/identity as well as the qualification/identity authenticated by the authentication server 130 .

The messaging server 150 provides a message transmission/reception service. The messaging server 150 may deliver the digital business card to the chat room in the form of a message, and through this, the business card may be shared among participants in the chat room.

When a digital business card-based chat service is requested, the messaging server 150 may provide a chat room in which a conversation with a card creator (card owner) is possible. The chat service provides a chat room accessible by using a link in an application and supports message exchange in the chat room. Here, the chat service is not limited to an acquaintance-based chat service, but may be a non-acquaintance-based chat service or an anonymous-based chat service, and may be replaced by various types and names of chat services that provide chat rooms. do. The busy person-based chatting service or the anonymous-based chatting service may be, for example, an open chatting service provided by the KakaoTalk application. In a chat room opened via a digital business card, a business card creator can exchange messages with a non-acquaintance counterpart, and the other party can participate in the chat room through a temporary profile that is randomly or temporarily assigned instead of a real-name-based profile.

The channel service server 170 may manage a channel opened for business and provide various information issued in the channel to a terminal. A user may subscribe to a channel through an add channel action, and the channel service server 170 may provide information issued in the channel to a terminal of a user account. The channel service server 170 interworks with the digital business card server 110 and terminals that store business cards connected to the channel, and may support various information issued in the channel to be provided through the business card.

The digital business card server 110 and the terminal 200 may check business card generation qualification based on identity authentication, and may proceed with a business card generation procedure when the business card generation qualification is confirmed. The digital business card server 110 may proceed with a business card generation procedure after authenticating the creator through interworking with the authentication server 130 . Qualification for creating a business card may be granted through a signature on a certificate issued based on identity authentication or verification of an account certified by a person. As such, since the digital business card server 110 creates a business card based on a real name that is authenticated rather than anonymously, it can provide reliability to the business card creator.

The digital business card server 110 may support a user to create a plurality of business cards.

The digital business card server 110 may set business card creation conditions in addition to the card creation qualifications based on identity authentication, and limit the creation of business cards only to users who satisfy the business card creation conditions. For example, the digital business card server 110 may determine that the business card generation condition is satisfied when the age meets the criterion (eg, 14 years of age or older) and there is no penalty according to the operating policy.

The digital business card server 110 provides an interface screen for generating a digital business card to the terminal 200 . The digital business card server 110 provides an interface screen for receiving information constituting a business card and providing an interlocking procedure necessary for authentication of a creator. The interface screen includes basic information freely written by the creator (name, photo, introduction information, contact information, social media service, etc.), the qualification/identity of the creator authenticated in the authentication server 130, and the channel of the application owned or managed by the creator. , use of chat function, etc. can be input. The social media service may include, for example, brunch, Kakao TV, YouTube, and Instagram. The digital business card server 110 may attach an authentication mark to the qualification/identity of the creator authenticated by the authentication server 130 .

The digital business card server 110 may manage business cards and keep information included in business cards up to date. The digital business card server 110 inquires the authentication server 130 about whether the qualification/authentication of each business card is valid, and may delete the invalid qualification/identity from the business card according to the response of the authentication server 130. The digital business card server 110 periodically checks whether or not the qualification/identity added to the business card is changed, and then maintains or deletes the exposure in the business card, or updates the business card based on the qualification/identity change information. To this end, the digital business card server 110 may periodically inquire the digital ID API of each qualification/identity to the authentication server 130 .

The digital business card server 110 may store the business card requested to be stored by the terminal in the storage box of the corresponding user account, and provide the business cards stored in the storage box to the terminal.

The digital business card server 110 may manage generated business cards. The digital business card server 110 may manage business card information such as job, professional field keyword, connected channel, connected qualification/certification, etc. included in the business card, and provide recommendation information to terminals based on this. The digital business card server 110 may record business card sharing information and business card storage information, track sharing and storage of business cards, and generate various statistical information. The sharing information of the business card may include a sharing requester who requested sharing of the business card, a sharing receiver receiving the shared business card, and the number of times of sharing. The storage information may include a storage person who stores the business card, the number of storage times, and the like.

The terminal 200 displays an interface screen provided by the digital business card server 110 and generates a business card according to information input on the interface screen. The terminal 200 may manage at least one generated business card as 'my business card' and generate a plurality of my business cards. The terminal 200 may store other people's business cards in a user account storage box. The business cards stored in the storage box can be called 'store business cards'. The terminal 200 may share my business card or stored business card.

2 and 3 are examples of interface screens for creating digital business cards.

Referring to FIGS. 2 and 3 , the terminal 200 enters a digital business card service (eg, 'talk business card' service of the KakaoTalk application) through an entry point implemented in the application, and obtains identity authentication and consent to use. After going through, the business card generation interface screen 300 provided by the digital business card server 110 may be displayed. The interface screens 300 (300-1 to 300-4) display a layout for receiving information for creating a business card, and may be designed in various ways according to the configuration items of the digital business card.

The interface screen 300-1 may display items for receiving essential information of a business card. Required information may include, for example, name, occupation, area of expertise, and business card address (URL). A photo item may be additionally provided so that the user can register a photo in the business card. The interface screen 300-1 may request a new input when a forbidden word is included in the essential information item. Alternatively, the digital business card server 110 may reject registration or restrict use by post-inspection of the digital business card.

A name is entered in the name item (1), and the name may be a real name or a nickname. Up to 20 characters including Korean, English, numbers, and spaces can be entered. If the real name is included in the name item (1) compared to the real name registered in the application account information, the real name authentication mark may be attached to the business card. The real name certification mark is a user-selected item and can be exposed on the business card after user consent. For example, the user can input 'Kim Ryan' in the name field (1).

Occupation is entered in occupation item (2), and it can be entered within 20 characters including Korean, English, and spaces. For example, the user may input 'lawyer' in the occupation item (2).

A plurality of (for example, up to three) keywords related to occupations may be input to the field of expertise item 3 . For example, the user can enter 'mergers and acquisitions', 'patent infringement', and 'corporate advisory' in the field of expertise (3).

A business card address that is not duplicated may be input to the business card address (URL) item (4). For example, the user may input 'namecard.kakao.com/vincenzo' in the business card address field (4).

The interface screen 300-2 may display items for receiving additional information of the business card. The additional information may include, for example, an introduction, a related link, use of a chatting function, qualification/identity, a channel to connect to, and only me setting.

An introductory phrase of a certain length (eg, within 60 characters) may be input in the introductory item 5 . The user can specifically introduce himself through the introduction item 5 and can freely describe information to be exposed.

A social media service address may be input in the related link item 6 . The social media service may include, for example, brunch, Kakao TV, YouTube, and Instagram. The user can promote his/her SNS and website through the related link item 6, and can expose the SNS and website of interest.

When the chatting function use item 7 is selected (activated), a chatting function providing a chatting service can be applied to the business card. For example, a business card with a chat function displays a chat button to enter a chat room where you can have a conversation with the card creator, provides a menu to enter the chat room, or specifies a user action to enter the chat room. It can be. A user action capable of entering a chat room may be designated as, for example, pushing a business card sideways, pushing up, pushing down, pressing and holding a business card, and the like. In the description, it is mainly described as entering a chat room through a chatting button displayed on a business card, which is just one embodiment of providing a business card-based chatting service. Even after creating a business card, the user can freely activate/deactivate (ON/OFF) the chat function use item 7.

In the case of a business card for which the chatting function use item 7 is selected, a plurality of one-to-one (1:1) chat rooms (eg, up to 100) may be provided by the messaging server 150 . Other participants may be added to the opened one-on-one chat room. Through a business card with a chat function, anyone can enter a chat room where they can communicate with the creator of the business card. For example, the other party can have a conversation with the business card creator in an 'open chat' chat room entered anonymously in a non-acquaintance relationship with the business card creator. The creator of the business card becomes the host of the chat room, and the other party who enters the chat room becomes a guest. Therefore, the guest can communicate with the card creator without exposing their contact information, and the card creator can also communicate with the guest through the chat room even if they do not list their contact information on the business card, reducing the potential risk of personal information exposure. can Here, it is simply explained that whether or not to use the chat function is selected, but if the card creator does not wish to communicate with anonymous guests or guests who are not related to the business card, specific details about the chat function A screen for setting conditions can be provided. For example, according to the selection of a business card creator, a guest may be restricted from entering a chat room related to business cards with a profile based on a real name. For example, age, gender, address, etc. may be set as conditions for entering a chat room according to a selection of a business card creator.

Meanwhile, a chat room opened by a business card may include an export function. Business card creators can export guests who have entered the chat room. Even if the other party who has been exported requests a chatting service in a business card, entry into the chatting room may be blocked. A chat room opened by a business card may include a reporting function. If the card creator conducts an illegal/unhealthy conversation in the chat room, the guest can report the card creator, and depending on the reported conversation, the card creator may be restricted from using the business card.

The qualification/identity of the user managed in the authentication server 130 may be linked to the business card through the qualification/identity connection item 8 . When the qualification/identity connection item 8 is selected, an interface screen 300-3 as shown in FIG. 3 may be displayed. The interface screen 300 - 3 may display a user's qualification/identity managed by the authentication server 130 in conjunction with the authentication server 130 . The user may select a qualification/identity to be displayed on the business card on the interface screen 300-3. The selected qualification/identity is displayed on the business card, and an authentication mark may be attached. Qualifications/identities can be managed, for example, in the ‘Wallet’ service of the KakaoTalk application, and through ‘wallet connection’, the qualifications/identities managed in the ‘wallet’ can be linked to business cards.

Through the channel connection item 9, a channel opened or managed by a user for business in an application may be connected to a business card. In addition to the user's direct management channel, a channel to which the user belongs among channels opened in the application may be connected to the business card. When the channel connection item 9 is selected, an interface screen 300-4 as shown in FIG. 3 may be displayed. The interface screen 300-4 may display a list of channels for which the user is a master or manager by interworking with the channel service server 170 that provides the channel service. The user may select a channel to be displayed on the business card on the interface screen 300-4. The selected channel is displayed on the business card, and when the displayed channel is selected (clicked), you can move to the corresponding channel.

11 is a flowchart of a method of generating a business card based on identity authentication according to an embodiment.

Referring to FIG. 10 , the terminal 200 executing the application receives a business card generation request from the main screen providing a digital business card service (S110). The terminal 200 may move to a main screen (eg, a call card screen) providing a digital business card service through an entry point implemented in an application.

The terminal 200 determines whether the account requesting the creation of the business card has qualifications for creating the business card based on personal authentication (S120). The terminal 200 may determine that the account that has been requested to create a business card is qualified to create a business card if the account has been authenticated. Alternatively, the terminal 200 may determine that the terminal 200 is qualified to create a business card if there is a signature for a certificate issued based on identity authentication. The terminal 200 may receive a signature for a certificate each time a business card is generated and grant business card creation qualifications, or if the signature input when generating a previous business card is valid, it may grant business card creation qualifications.

When the terminal 200 is qualified to generate a business card and satisfies the remaining business card creation conditions, it initiates a business card generation procedure (S130). The terminal 200 may display the business card creation interface screen 300 of FIG. 2 .

If, if the qualification for creating a business card based on identity authentication has not yet been obtained, the terminal 200 interworks with the application system 100 and proceeds with a identity authentication procedure to obtain qualification for creating a business card (S140). When the identity verification process is completed, the terminal 200 may proceed to determining whether or not it has business card generation qualifications (S120) again. The identity authentication process is performed according to business card creation qualifications required by the digital business card service, and may be a identity authentication process for an account or a certificate issuance and signing process based on identity authentication.

12 is a flowchart of a method for generating a business card based on a certificate according to an embodiment.

Referring to FIG. 12 , the business card module of the terminal 200 receives a business card creation request from the main screen providing the digital business card service (S210). The terminal 200 may move to a main screen (eg, a call card screen) providing a digital business card service through an entry point implemented in an application.

The business card module of the terminal 200 determines whether a certificate issued based on identity authentication exists (S220). If there is no issued certificate, the terminal 200 may display a guide indicating that certificate issuance is required to create a business card. On the other hand, the business card creation conditions for initiating the business card generation process may be set in various ways, in addition to the card creation qualifications based on identity authentication. It can include less than 3 business cards and consent to essential items of use. If the business card generation condition is not satisfied, the terminal 200 may end the business card generation procedure even if a certificate issued based on identity authentication exists. Through this, it is managed so that only users who satisfy the business card creation conditions can generate business cards. If there is a business card generated through the signature on the certificate, the terminal 200 checks the signature completion history, and if the remaining business card creation conditions are satisfied, the terminal 200 moves to step S272 to initiate the business card generation process.

If it is the first business card generation or if there is no signature completion history for the certificate, the business card module of the terminal 200 requests the digital business card server 110 to proceed with the certificate-based business card generation signature procedure (S222). The business card generation signature procedure may proceed as follows, for example, and the following procedure may be variously designed.

The digital business card server 110 requests issuance of a transaction identifier (tx_id) to the authentication server 130 (S230).

The digital business card server 110 receives a transaction identifier (tx_id) from the authentication server 130 (S232). The digital business card server 110 stores a transaction identifier (tx_id) and a user account (account id).

The digital business card server 110 informs the business card module of the terminal 200 that the transaction identifier (tx_id) needs to be signed (S234).

The authentication module of the terminal 200 checks the certificate corresponding to the transaction identifier (tx_id) and displays a screen requesting a signature for the certificate (S250).

The authentication module of the terminal 200 receives information for signing the certificate (S252). Signing of the certificate may be performed using a password or biometric information.

The authentication module of the terminal 200 responds to the completion of the signature corresponding to the transaction identifier (tx_id) to the business card module (S254).

The business card module of the terminal 200 transmits the completion of the signature to the digital business card server 110 (S256).

The digital business card server 110 requests verification of signature completion for the transaction identifier (tx_id) to the authentication server 130 (S260).

The digital business card server 110 receives a signature completion confirmation for the transaction identifier (tx_id) from the authentication server 130 in response (S262).

The digital business card server 110 records the completion of the signature for the user account (account id) (S264).

The business card module of the terminal 200 interworks with the digital business card server 110 and confirms completion of business card creation and signature (S270).

The business card module of the terminal 200 confirms business card generation qualification through certificate-based identity authentication, and initiates a business card generation process (S272). The business card module of the terminal 200 may display the business card creation interface screen 300 of FIG. 2 .

In this way, since the digital business card is created after the signature on the certificate is completed, real name authentication is possible, and even if a nickname is used as a business card activity name, reliability for the business card creator can be provided.

13 is a flowchart of a method of generating a business card including an authenticated qualification/identity according to an embodiment.

Referring to FIG. 13 , the terminal 200 displays a business card creation interface screen (S310).

The terminal 200 transmits the qualification/identity connection request entered on the business card creation interface screen to the digital business card server 110 (S320). The qualification/identity association request is a request for linking the authenticated qualification/identity managed by the authentication service to the business card. Here, the authentication service is a service that manages certified qualifications and identities, including certificates issued by users, and may be, for example, the 'wallet' service of the KakaoTalk application.

The digital business card server 110 requests a qualification/identity list for a user account (account id) from the authentication server 130 (S330). The authentication server 130 authenticates the user's qualification/identity and manages the digital ID assigned to the qualification/identity. Qualification is a qualification issued by an institution that the authentication server 130 interworks with, and may include national qualification as well as private qualification. The identity may be an identity belonging to an organization or a company with which the authentication server 130 interoperates.

The digital business card server 110 obtains the user's qualification/identity list from the authentication server 130 (S332) and transmits the user's qualification/identity list to the terminal 200 (S334).

The digital business card server 110 interworks with the authentication server 130 to periodically check whether the user's qualification/identity has changed (S360). Whether or not to change may be determined by whether the period for the qualification/status with a valid period has expired, whether the validity period for the qualification/status with a valid period has been extended, whether there is a change in status such as withdrawal/resignation, change in position/position, change in affiliation, etc. there is.

The digital business card server 110 updates the user's business card based on the qualification/identity change information (S362).

The digital business card server 110 provides the terminals with the changed qualification/identity of the business card (S364). The digital business card server 110 updates the business card including the changed qualification/identity, so that the updated business card is displayed in the terminals. For example, the digital business card server 110 is terminals that manage business cards including expired qualifications/identities as my business cards or storage cards, requesting deletion of expired qualifications/identities, or expiration of qualifications/identities. can inform The digital business card server 110 may return the changed qualification/identity to the terminal that has requested qualification/identity inquiry of the business card.

The terminal 200 displays my business card reflecting the changed qualification/identity on the interface screen (S370). For example, the terminal 200 may display my business card from which expired qualifications/identities have been deleted. Terminals that display the business cards generated by the terminal 200 in the stored business card list may also display stored business cards reflecting the changed qualifications/identities on the interface screen.

In this way, since the digital business card includes the authenticated qualification/identity, reliability of the qualification/identity can be provided, and damage caused by impersonation of qualification/identity can be fundamentally eliminated. In addition, since digital business cards in storage are always automatically updated with current qualifications/status, the card creator does not have to check and change changes in qualifications/status, and the business card information modified by the card creator, including changes in qualifications/status, It is automatically reflected in the archived digital business card, so there is no need to redistribute the business card.
