Abstract

Using small cameras such as smartphones, criminals shoot secretly in public restrooms and women's changing rooms. And Revenge porn is also increasing. As a result social damage is increasing. Tumblr is an overseas service and it is very difficult to work with Tumbler on international legal cooperation and deletions. Thus In order to block the distribution of videos, victims must find and report the video URL themselves. But it's hard for victims who lack IT expertise to proceed those procedure. In this study, we automatically collect the URL of stored information and hash values of the images from API permlink of Tumbler blog. It is then saved as a document file with and presented to the victim. Through these technical methods, we can help victims report violations easily and quickly.

스마트폰을 비롯한 다양한 고해상도의 소형 카메라를 이용해 여성들이 이용하는 대중화장실과 탈의실 같은 장소에서 몰래 촬영한 영상이나 리벤지 포르노 동영상 같은 비동의 영상물의 유포행위로 인한 피해가 증가하고 있다. 특히 해외 서비스인 텀블러의 경우 국제공조 및 차단 삭제 등 협조가 어려워 재유포 차단을 위해서는 피해자가 직접 영상물 URL을 찾아 신고하여야 한다. 그러나 IT 전문성이 부족한 피해자가 이러한 절차를 진행하기가 어려워 피해가 가중되고 있다. 이에 본 연구에서는 텀블러 블로그의 API 퍼머링크에서 비동의 영상물의 저장 정보 URL과 해시(Hash)값을 자동으로 수집 한 후, <영문 삭제 요청서 예시문>과 함께 저장된 문서파일을 피해자에게 제공하여 쉽고 빠르게 침해신고를 할 수 있도록 지원하는 기술적 방안을 제안한다.
