Abstract

This paper proposes Personal Information Auto Detection(PIAD) System to prevent leakage of Personal informations in document and image files that can be used by mobile service provider. The proposed system is to automatically detect the images and documents that contain personal informations and shows the result to the user. The PIAD is divided into the selection step for fast and accurate retrieval images and analysis which is composed of SURF, erosion and dilation, FindContours algorithm. The result of proposed PIAD system showed more than 98% accuracy by selection and analysis steps, 267 images detection of 272 images.

본 논문에서는 통신 판매사에서 사용하는 문서와 이미지 파일에서 개인 정보의 유출을 방지할 수 있는 개인 정보 자동 검색(PIAD, Personal Information Auto Detection) 시스템을 제안한다. 제안하는 시스템은 개인 정보를 포함하는 신분증과 계약서 이미지를 자동으로 검색하고 그 결과를 사용자에게 전달하고, 문서상의 개인 정보 또한 검출할 수 있다. 본 시스템은 빠르고 정확한 검색을 위하여 선별 과정과 분석 과정으로 나뉘고, 분석 과정은 SURF, 침식과 팽창, FindContours 알고리즘들을 사용한다. 제안하는 PIAD 시스템은 272장의 입력 이미지들 중 267장을 선별 및 검출함으로써 98% 이상의 정확도를 보였다.
