That is, in the following, it means that each step is performed by one of the terminal device 100 and the service device 200.

First, the method for authenticating a messenger user according to the present invention starts as the terminal device 100 or the service device 200 confirms a messenger service request (S105). The messenger service request is generated when a user accesses a service page provided by the service device 200 through the terminal device 100 or installs and executes the messenger service execution module 111 installed in the terminal device 100. Can be.

When the messenger service request is confirmed, the terminal device 100 or the service device 200 checks device information and number information for the terminal device 100 used by the user (S110). This acquires device information and number information stored in the terminal device 100 through the messenger service execution module 111 of the terminal device 100, and compares it with device information and number information set in the messenger service execution module 111 , The service device 200 may receive device information and number information from the terminal device 100 and compare it with previously stored device information and number information.

As a result of checking, if the device information and number information of the terminal device 100 currently being used matches the previously registered device information or number information (S115), the terminal device 100 and the service device 200 are previously stored. While fetching and outputting the service history, a messenger service for exchanging messages with one or more other terminal devices according to user selection is performed (S160).

On the other hand, if the device information and number information of the terminal device 100 currently being used does not match the previously registered device information or number information (S115), the terminal device 100 or the service device 200 It is checked whether the number change has occurred (S120). This may be accomplished by the terminal device 100 or the service device 200 inquiring whether a device or number change has occurred to the user and confirming a user input thereto.

As a result of the verification, when no change of the device or number has occurred, for example, when the user uses the messenger service for the first time, the terminal device 100 or the service device 200 transfers the messenger service to a unique key that is a unique value for the user. Is created and assigned (S125). The unique key has a unique value and may be generated through a random number generation algorithm or various hash algorithms. In addition, the unique key generated in this way is provided to the user so that the user can recognize it.

Then, the terminal device 100 or the service device 200 maps and registers the assigned unique key and authentication medium information that can be used by the user who has requested the messenger service (S130). In this case, the terminal device 100 or the service device 200 may further map and store device information and number information for the terminal device 100 requesting the messenger service to the unique key.

In addition, the terminal device 100 or the service device 200 may execute a messenger service according to a user input (S160). Thereafter, the service history executed through the messenger service may be stored in the terminal device 100 or the service device 200. When stored in the service device 200, the service history may be managed based on one or more of a unique key, device information, and number information.

On the other hand, in the case of a device or number change in step S120, the terminal device 100 or the service device 200 receives or receives a unique key from the user (S135). At this time, the unique key provided by the user becomes the unique key assigned when using the first messenger service.

Then, the terminal device 100 or the service device 200 extracts authentication medium information mapped to the unique key (S140). Here, the authentication medium information is user account information on a medium capable of user authentication, for example, email account information, landline phone number, service ID other than messenger service (e.g., portal site ID or mobile communication service ID, etc.) ), etc.

Then, the terminal device 100 or the service device 200 performs user authentication based on the extracted authentication medium information (S145). Here, user authentication may be performed differently depending on the type of authentication medium. For example, in the case of a landline phone, it may be performed in the ARS method, and in the case of an email account, after transmitting a predetermined authentication number to the email account , It can also be done in a way that allows input.

After authentication is successful (S150), the terminal device 100 or the service device 200 acquires and integrates the previous service history of the authenticated user (S155), and then performs a messenger service (S160).

The messenger user authentication method described above will be described in more detail for each embodiment with reference to FIGS. 5 to 6. For reference, in FIGS. 5 to 6, the users of the first and second terminal devices 101 and 102 are the same, but the first terminal device 101 is a device that the user first uses, and the second terminal device 101 is It is assumed that the device is changed by the user or the number is changed.

5 is a flowchart illustrating an operation process of the messenger service system according to the first embodiment of the present invention.

The user may request a messenger service from the service device 200 through the first terminal device 101 (S205). In this case, it is assumed that the user first requests a messenger service through the first terminal device 101.

In this case, since the device information and number information of the first terminal device 101 is not registered, the service device 200 generates and assigns a unique key for the messenger user according to the user's confirmation (S210).

Then, the service device 200 maps and registers the assigned unique key and authentication medium information that can be used by the user who has requested the messenger service (S215). The authentication medium information may be provided from a user or may be obtained from another external device. In this case, the service device 200 may further map and store device information and number information for the terminal device 100 requesting the messenger service to the unique key.

Then, the service device 200 provides the generated unique key to the user through the first terminal device 101 (S220).

Thereafter, the first terminal device 101 executes the messenger service through the messenger service execution module 111 (S225), and stores the service history made through the messenger service, that is, the user's message transmission/reception history. ) To (S230).

The steps S225 to S230 are repeatedly performed in the first terminal device 101.

Then, before changing the device or changing the number, the user uploads the service history stored in the first terminal device 101 to the service device 200 (S230) and stores it in the service device 200 (S240). . In this case, the unique key assigned to the user may be transmitted together and mapped to the service history to be stored.

Thereafter, the user who uses the second terminal device 102 through device change or number change may request a messenger service from the service device 200 again through the second terminal device 102 (S245).

At this time, since the second terminal device 102 has a device change or a number change, the service device 200 determines that the device information or number information of the second terminal device 102 does not match the registered information. (S250).

Accordingly, the service device 200 may request and receive a unique key through the second terminal device 102 (S255 and S260).

Then, the service device 200 extracts the user's authentication medium information mapped to the unique key, and performs user authentication using this (S265, S270).

And, if the authentication is successful, the service device 200 transmits the service history previously received and stored from the first terminal device 101 to the second terminal device 102 (S275).

Upon receiving the service history, the second terminal device 102 stores the received service history as a current messenger service, and performs a messenger service (S285). Accordingly, the history of the messenger service performed in step S285 may be integrated with the previously stored service history.

Next, FIG. 6 is a flowchart illustrating an operation process of the messenger service system according to the second embodiment of the present invention.

Also in the second embodiment of the present invention, the user may request a messenger service from the service device 200 through the first terminal device 101 (S305). In this case, it is assumed that the user first requests a messenger service through the first terminal device 101.

In this case, since the device information and number information of the first terminal device 101 is not registered, the service device 200 generates and assigns a unique key for the messenger user according to the user's confirmation (S310).

Then, the service device 200 maps and registers the assigned unique key and authentication medium information that can be used by a user who has requested the messenger service (S315). The authentication medium information may be provided from a user or may be obtained from another external device. In this case, the service device 200 may further map and store device information and number information for the terminal device 100 requesting the messenger service to the unique key.

Then, the service device 200 provides the generated unique key to the user through the first terminal device 101 (S320).

Thereafter, the first terminal device 101 performs a messenger service through the service device 200 (S325). Here, the messenger service is performed under the control of the service device 200, and the service history performed through the messenger service, that is, the user's message transmission/reception history is stored in the service device 200 (S330). In this case, the service device 200 may store a service history by mapping to any one of a unique key allocated to a user, device information, and number information.

The steps S325 to S330 are performed repeatedly.

Thereafter, a user who uses the second terminal device 102 through a device change or a number change may request a messenger service from the service device 200 again through the second terminal device 102 (S335).

At this time, since the second terminal device 102 has a device change or a number change, the service device 200 determines that the device information or number information of the second terminal device 102 does not match the registered information. (S340).

Accordingly, the service device 200 may request and receive a unique key through the second terminal device 102 (S345 and S350).

In addition, the service device 200 extracts the user's authentication medium information mapped to the unique key, and performs user authentication using the extracted information (S355 and S360).

And, if authentication is successful, the service device 200 maps and integrates the stored service history to the second terminal device 102 (S365), and then, based on the integrated service history, the second terminal device ( 102) and performs a messenger service (S370).
