4 is a flowchart illustrating a method of providing a private message service in a messenger service according to an exemplary embodiment of the present invention.

1 and 4, in order to perform a private message service in a messenger service, a step of executing a messenger program in a calling terminal is performed first. (Step S10)

When the messenger program is executed in the calling terminal, the user decides whether to create a private message in the calling terminal (step S20)

Then, when the originating terminal creates a private message, the originating terminal creates a message to be included in the private message, generates a hint to suggest an answer for browsing the message, and an answer to the hint (Step S30).

In one embodiment of the invention, a private message may be sent to one user, a plurality of users, or a group of users, respectively.

In an embodiment of the present invention, in the step of providing a private message (step S30), the hint may be a clue, a number, or a specific number of hints commonly known by the user of the originating terminal that created the private message and the user of the receiving terminal that received the private message Location, hobby, and terminal lock pattern.

When an answer to the hint and hint to be included in the private message is generated, a private message including a message, a hint and an answer is provided from the calling terminal to the service device 200 via the communication network 300.

In an embodiment of the present invention, before providing the private message to the service device 200 (step S40), the user of the originating terminal that created the private message sends a response to the user of the receiving terminal Can be provided in advance.

When the service device 200 receives the private message including the message, the hint and the answer from the calling terminal, the service device 200 provides the receiving terminal with the hint provided from the calling terminal (step S50).

Although it is shown and described that the service device 200 provides hints to the receiving terminal in one embodiment of the present invention, the service device 200 may transmit hints and messages to the receiving terminal together .

When the service device 200 provides the hint and the message together with the receiving terminal, the receiving terminal can browse the private message more quickly.

If the receiving terminal wishes to view the private message provided from the service device 200 (step S60), the user inputs an answer to the hint through the receiving terminal, and the receiving terminal answers the hint to the service device (Step S70)

When the answer provided from the receiving terminal is provided to the service device 200 through the communication network 300, the service device 200 determines whether the answer provided from the receiving terminal and the answer provided from the calling terminal coincide with each other (step S80) If the answer is the same, the service device 200 provides the message included in the private message to the receiving terminal, thereby reading the private message from the receiving terminal. (Step S90)

5 to 8 are views illustrating an example of a non-public message service according to an exemplary embodiment of the present invention.

Referring to FIG. 5, when the user of the originating terminal desires to send a private message to a specific user during a public conversation in the public chat room, a specific icon is selected to execute a private message service.

When the private message service is executed, for example, a check box for selecting whether to create a private message in a part of the screen and a window for selecting a recipient to receive the secret message are activated.

When the user selects a check box for composing a private message and selects a recipient to receive a secret message, a hint input window for inputting a hint, an answer input window for inputting an answer to the hint, and a message to be included in the private message The input message input window may be activated, and the recipient may be a group consisting of one person, a plurality of persons, or a plurality of persons.

The user inputs a selection check box, a recipient selection, a hint input, an answer input, and a message for creating a private message, and then pushes the dispatch button. Thus, the calling terminal transmits the hint to the service device 200 via the communication network, A private message containing the message is provided.

Referring to FIG. 6, when a secret message is provided from the originating terminal to the service device 200, the service device 200 provides a hint included in the private message to the recipient terminal of the recipient included in the private message.

When the private message is received during the public conversation, the receiving terminal displays the blanked box together with the lock indication, so that the user of the receiving terminal recognizes that the private message has arrived.

Referring to FIG. 7, when the user of the receiving terminal clicks the lock display, the dialogue window displays a guideline for the authentication of the user and a hint input by the user of the calling terminal in the hint input window, and an answer input window for inputting an answer is activated do.

The user of the receiving terminal refers to the displayed hint, inputs the answer to the answer input window, and then depresses the dispatch button, so that the receiving terminal provides the answer to the hint to the service apparatus 200. [

The service device 200 compares the answers provided from the originating terminal with the answers provided from the recipient terminal, and when the answer provided from the originating terminal and the answer provided from the recipient terminal match, the service device 200 receives the answer from the originating terminal, A message provided from the terminal is provided to the receiving terminal so that the receiving terminal can confirm the message.

Of course, the private message can be made available only to the recipient or recipient group selected by the originating terminal.

As described above in detail, in order to allow a private message to be delivered and confirmed to a specific person during a public conversation through a messenger service, the transmitting terminal executes a private message service through a messenger program and includes a reply to a message, a hint and a hint And transmits the created private message to the receiving terminal through the service device and the communication network. The receiving terminal provides the answer to the hint to the service device. The answer to the hint provided by the transmitting terminal in the service device, If the answer to the hint provided by the receiving terminal is identical, the message included in the private message is provided to the receiving terminal so that the receiving terminal can confirm the message. In particular, when a large number of users simultaneously talk in one public chat room, To the balls It has the effect of making it easy to send messages.

It should be noted that the embodiments disclosed in the drawings are merely examples of specific examples for the purpose of understanding, and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.

The present invention can be applied to a private message service capable of delivering a private message to a specific person or a specific group during a conversation in a public chat room. The public message can be communicated to a specific person through a messenger service The transmitting terminal executes the private message service through the messenger program to create a private message including the answer to the message, the hint and the hint, transmits the created private message to the receiving terminal through the service device and the communication network, If the answer to the hint provided by the transmitting terminal and the answer to the hint provided by the receiving terminal match, the service device provides a message included in the private message to the receiving terminal, Mesh To be resolved.
