(B) confirming whether the received message is set in a hidden setting mode from the receiver when the confirmed result is confirmed as the hidden message; (C) displaying the received hidden message on an independent position separately from a region of the display unit of the device by instructing the received message to be processed by a hidden message processing unit when the received message is the hidden message set by the transmitter and set in the hidden mode state set by the receiver, and (D) hiding the hidden message displayed on the display unit after a predetermined constant time. ## Claims ### Claim 1 A method for providing a message hidden service in a chatting window comprising: (A) confirming whether a received message is a message set as a hidden message from a transmitter when the message is received from a chatting server; (B) confirming whether the received message is set in a hidden setting mode from the receiver when the confirmed result is confirmed as the hidden message; (C) displaying the received hidden message on an independent position separately from a region of the display unit of the device by instructing the received message to be processed by a hidden message processing unit when the received message is the hidden message set by the transmitter and set in the hidden mode state set by the receiver; (D) hiding the hidden message displayed on the display unit after a predetermined constant time; and (E) transmitting a processing result of the received message to the transmitter terminal. ### Claim 2 (depends on 1) The method for providing a message hidden service in a chatting window of claim 1, further comprising: performing an authentication procedure by displaying a personal authentication confirmation window for performing unhiding by a personal authentication unit on the display unit when the unhiding of the hidden message is selected from the receiver; and selecting a message to be unhidden from the messages which have been hidden by an unhidden processing unit and displaying the hidden message on the display unit by unhiding the selected hidden message when the user authentication is confirmed through the authentication procedure. ### Claim 3 (depends on 2) The method for providing a message hidden service in a chatting window of claim 2, wherein the authentication procedure includes: displaying a password input window transparently on the display unit; and inputting a password by a user using a key board in a general message screen, wherein when the user inputs the password by using the keyboard while the password input window is displayed on the screen, the input password is not displayed on the screen. ### Claim 4 (depends on 2) The method for providing a message hidden service in a chatting window of claim 2, wherein when the hidden message is displayed on the display unit, the hidden message is displayed together with a date and a time received together with the message. ### Claim 5 (depends on 2) The method for providing a message hidden service in a chatting window of claim 2, wherein the hidden message to be unhidden is configured by displaying only some of the hidden message on the display unit by unhiding the hidden message at a corresponding position when a region where the hidden message is positioned is selected from the messages displayed on the chatting window, and displaying all of the hidden message on the display unit by unhiding the hidden message of the transmitter when the transmitter displayed on the upper end of the chatting window is selected. ### Claim 6 (depends on 1) The method for providing a message hidden service in a chatting window of claim 1, wherein in step (B), before the transmitter to transmit the hidden message transmits the hidden message, the transmitter first transmits the hidden message transmission to the receiver and the receiver approves the hidden message transmission received from the transmitter. ### Claim 7 (depends on 1) The method for providing a message hidden service in a chatting window of claim 1, wherein in step (C), the hidden message or the unhidden message is displayed on a separate window or an independent position separately from a region of the display unit where the general message is displayed. ### Claim 8 (depends on 1) The method for providing a message hidden service in a chatting window of claim 1, wherein step (C) includes receiving a continuous hidden mode setting request during the hidden mode request and processing the reception as the continuous hiding, and collectively hiding until at least one of the transmitter and the receiver until performs the unhiding. ### Claim 9 (depends on 1) The method for providing a message hidden service in a chatting window of claim 1, further comprising: forcibly setting, by the transmitter, a message hidden service setting; and selecting, by receiver, the forcibly set message transmitted by the transmitter to be received as the hidden message or not to be received as the hidden message. ### Claim 10 (depends on 1) The method for providing a message hidden service in a chatting window of claim 1, further comprising: adding, by the transmitter, an identification function to a menu of a hidden message; and taking and transmitting a live picture as soon as other party confirms the hidden message when the receiver is waiting and transmitting live confirmation or a snapshot during the chatting. ### Claim 11 (depends on 1) The method for providing a message hidden service in a chatting window of claim 1, wherein in step (C), the hidden message displayed on the display unit provides at least one of displaying the “hidden message” on the upper end of the message so that the receiver determines the hidden message, displaying a highlight on an edge of a speech bubble, displaying the inside of the speech bubble with different colors, and displaying blinking on the speech bubble, and when the received message is the hidden message set by the transmitter and the hidden mode setting is not confirmed by the receiver, the hidden message is processed as the general message and the received hidden message is displayed on the display unit of the device as the general message. ### Claim 12 A method for providing a message hidden service in a chatting window comprising: (a) confirming whether a received message is a message set as a hidden message from a transmitter when the message is received from a chatting server; (b) confirming whether the received message is set in a hidden setting mode from the receiver when the confirmed result is confirmed as the hidden message; (c) displaying the hidden message received by the hidden message processing unit on the display unit of the device when the hidden message is set from the transmitter and the hidden setting mode is set from the receiver; (d) deleting the hidden message displayed on the display unit after a predetermined constant time; and (e) arranging the message displayed on the display unit by moving to a position parallel with a position where the hidden message is deleted after the hidden message. ### Claim 13 (depends on 12) The method for providing a message hidden service in a chatting window of claim 12, wherein when the hidden message is displayed on the display unit, the general message displayed in the hidden message is moved downward and displayed by a region where the hidden message is displayed. ### Claim 14 (depends on 12) The method for providing a message hidden service in a chatting window of claim 12, wherein in step (b), when a message is created and the created message is transmitted to the receiver, selective message transmission is provided through the selection of an option (general/hidden) of a transmission key.
