Publication number: 20250166402Abstract: The present disclosure relates to a method, device, and computer program capable of detecting whether a brand logo is illegally being used by an unauthorized person using an image and text of the brand logo. The present disclosure provides a detection technique capable of accurately detecting illegal use of a brand logo even when variously transformed forms and background images are used to avoid legal use detection. According to embodiments of the present disclosure, since the logo identification model can be generated through the machine learning dataset based on the logo transformation images and the image illegal use information can be generated using the logo identification model, it is possible to more accurately detect the illegal use of the logo that is used in variously transformed forms. In addition, since the illegal use information on the logo text can be considered in addition to the logo image, it is possible to further increase the accuracy of the illegal use detection.Type: ApplicationFiled: December 4, 2023Publication date: May 22, 2025Applicant: S2W INC.Inventors: In Wook HWANG, Ki Cheol KIM, Keun Tae PARK
