Pixel value graphical password: A passpix clustering technique for password fault tolerance

Abstract

The pixel value graphical password scheme was introduced to reduce the burden on memorizing a hard textual password and to hide the password information. It gives freedom for the user to utilizing their personal image their password, called PassPix, that makes it is more memorable and hidden in the same time. However, when the PassPix is travelled on a compressed media, the safety information that resides in the PassPix is transformed and demolishing its function as password. This study is aimed to propose the image clustering technique to solve the issues. This paper is organized into 4 sections where an explanation on graphical password scheme as the introduction in section 1, the problem of this study is stated in section 2, the idea of clustering technique is discussed in section 3, and section 4 as the conclusion of this article.
