Abstract

In this study, we propose a new Relative position pattern unlocking solution based on blind interaction, which is a new unlocking method, and compared it with existing unlocking methods to verify usability and security improvement. And verified the practical value of the proposed new unlocking solution. The relative position pattern unlock method is easily remembered than the numeric code method and is worth practical enough to show a degree of learning ease similar to the drawing pattern method. The new method is safer to steal than other two methods. It can be manufactured at a low cost and can also be used by special users such as blind people. Therefore, the practical value is relatively high.

본 연구에서는 현존하고 있는 잠금 해제 방식에서 보이는 문제점으로부터 출발해 보안성 및 사용성 측면에서 개선된 블라인드 인터랙션을 적용한 상대적 위치 기반 패턴 잠금 해제 방식을 제안하고 이론적 타당성을 고찰했다. 기존 숫자암호 잠금 해제 방식과 패턴 그리기 잠금 해제 방식과의 차이를 실험을 통해 확인하고 실용적 가치를 평가했다. 상대적 위치 패턴은 숫자 암호 보다 쉽게 기억되고 그리기 패턴과 비슷한 정도의 학습 용이성을 보여 주었고 타 방식에 비해 훔쳐보기 공격에 안전한 결과를 얻었다. 생체신호를 센싱 할 센싱 모듈을 사용할 필요 없이 터치스크린의 기본기능만으로 실현 가능하기에 적은 원가로 제작할 수 있다. 시각적 요소가 필요 없는 방식이기에 시각 장애인과 같은 특수 사용자들도 불편함 없이 사용할 수 있기에 실용적 가치도 상대적으로 높다.
