초록

텍스트 기반 패스워드 인증의 문제점을 해결하기 위해서 이미지를 사용하는 그래픽 패스워드가 발전 하였다. 기본적으로 그래픽 패스워드는 화면에 보이는 이미지 위의 정확한 점의 위치를 순서대로 선택(클릭)하여 인증을 처리하는 방식이다. 이러한 기존의 그래픽 패스워드 방식은 화면상의 정확한 지점을 선택하여 클릭하지 못하면 인식에 실패한다. 본 논문에서는 이러한 단점을 개선한 신 개념의 그래픽 패스워드 방식인 PassPositions를 소개한다. PassPositions는 지금까지의 그래픽 패스워드 방식에서 사용하지 않았던 상대위치를 패스워드 생성에 사용한 신개념의 그래픽 패스워드 기법이다. PassPositions는 유니버설 디자인에 기반을 둔 그래픽 패스워드 기법으로 사용자의 신체적 조건에 관계없이 모두가 편리하게 사용할 수 있다.

Graphical passwords using images have been developed to solve problems in text based password recognition. The basic recognition process scheme of graphical passwords is clicking certain points on the screen image in correct order. In this pre-developed method of graphical passwords the recognition will fail if the precise positions are not clicked. A new graphical password system called PassPositions is introduced in this paper. PassPositions is a new graphical password scheme which is using relative positions never used earlier graphical password schemes. PassPositions is a graphical password scheme based on universal design that everybody can use conveniently without regarding their physical conditions.
