Purpose: The purpose of this study is to increase the satisfaction of customers who want good physiognomy and appearance by creating a system that allows cosmetic plastic surgery professionals to automatically see the faces on screens such as those of mobile devices. Method: First, the name of each part of the face as a point on the coordinate plane. Second, the beauty plastic elements were first defined as math formulas, and criteria for determining beauty plastic images were prepared according to the calculation results of inputting information-protected coordinate values into the math formulas. Third, a method of outputting beauty plastic judgments when the math formulas in which the coordinates of feature points are input satisfies a given condition was presented. Results: Since philtrum is an important part of physiognomy and plastic surgery, a method of determining cri-teria related to philtrum was suggested. In addition, since the jawline shows a person s ability in terms of physi-ognomy, the ratio of the jawline was defined to present the criteria for an angled jawline. Conclusion: Experts in the service industry, such as physiognomy and cosmetic surgery, are habitually considering ways to analyze facial shapes and create better images according to customer needs. Since it takes time and effort to learn physiognomy professionally, if you have a tool to analyze physiognomy when you do not have knowledge of physiognomy, you can expect much more efficient results. Based on the effect of this paper, when the face appears on the screen, the customer s personality and image will react immediately, enabling the establishment of a system that suggests the direction of procedures for makeup, plastic surgery, and tattoos.
