SYSTEM AND METHOD FOR PROVIDING A SERVICE FOR SENDING A TEXT MESSAGE BY USING A BACKGROUND IMAGE BASED ON PREDICTION INFORMATION ON A FIELD OF INTEREST

摘要

The present invention relates to a system and method for providing a service for sending a text message by using a background image based on prediction information on a field of interest. More specifically, according to the present invention, prediction information on a field of interest of a smartphone user is generated on the basis of information on regular searches, purchase history, application download history, or the location of the user. Advertisements matching the prediction information on the field of interest are selected and transmitted to a smartphone in which an application for a background image for writing a text message is installed so that only interesting background images which consist of the advertisements suitable for the field of interest of the user are displayed on a background image of a text message input window, thereby improving advertising efficiency. Further, when the text message is inputted, the interesting background image located on an area where letters are displayed is removed automatically or by a touch operation of the user in order to display the text message. Therefore, without being affected by the interesting background image, readability can be improved when the text message is written.
