Abstract: Provided is a method for automatic user authentication, including: (a) a first step in which a user credential is stored on a website in the course of membership registration, wherein the user credential includes a given mobile phone number; (b) a second step in which a service application is downloaded onto a first mobile terminal, wherein the first mobile terminal is linked to the website server; and (c) a third step in which the service application is activated on the first mobile terminal through automatic user authentication without an additional membership registration process.

Abstract: Provided is a method of transforming a specific area of an image using a computer processor, the method comprising: receiving an input by the computer processor, wherein the input includes a xy starting point coordinate, a xy end point coordinate, and a vector direction extending from the xy starting point coordinate to the xy end point coordinate; defining, by the computer processor, a predetermined area around the xy starting point coordinate as a transformation area; and repeatedly moving back and forth in the vector direction, by the computer processor, the transformation area between the xy starting point coordinate and the xy end point coordinate.
