A method for identifying an originator based on an image, the method comprising: transmitting a session initiate protocol INVITE message by inserting predetermined image information in the session initiate protocol INVITE message at a transmitting terminal; and displaying the image at a receiving terminal by analyzing the predetermined image information included in the session initiate protocol INVITE message transmitted from the transmitting terminal to the receiving terminal, wherein the transmitting terminal transforms the predetermined image information into image data in a text format to be inserted into an opaque field of the session initiate protocol INVITE message, inserts the text formatted image data into the opaque field of the session initiate protocol INVITE message, and transmits the session initiate protocol INVITE message with the text formatted image data, and wherein the receiving terminal displays the image by extracting the text formatted image data from the opaque field of the session initiate protocol INVITE message, transforming the extracted image data into binary image data, decoding the binary image data into original image data using a decoder, and displaying the original image data.
