Graphical Password Authentication Using Image Segmentation Rohitkumar Kolay, Animesh Vora, Vinaykumar Yadav Department of Information Technology, Universal College of Engineering, Vasai, Maharashtra, India ---------------------------------------------------------------------***--------------------------------------------------------------------authentication system with extensive findings to support it. Graphical password authentication can be that are alphanumeric in nature. However, users find it difficult in remembering a password that is long and needs to implemented using two techniques - Recall based and be recalled again and again while implementing it. Instead, Recognition based. The basic idea of using the image they create short, simple, and insecure passwords that make segmentation system is that using images as a security the user’s data vulnerable to outside attacks. Graphical will lead to high memorability and decrease the passwords provide a way out of this dilemma by making chances to choose insecure passwords. This, in turn, passwords more rememberable and easier for people to use as should increase overall password security. Our primary a password and, therefore, makes it more secure. Using a question is the following: Are graphical passwords graphical password, users clicks on images rather than typing competitive to alphanumeric passwords in terms of text passwords which contains alphanumeric characters. A security, performance and retention? new and more secure graphical password system has been

developed which uses image segmentation. The image segmentation system presents the user with an image upon which the user selects a number of grids on this image; when entered in a proper sequence these points authenticate the user. The findings showed alphanumeric passwords and graphical passwords both worked in similar time but the graphical passwords were easier to recall and remember.[1] Thus, Graphical passwords were found to be hard to crack as they are newly implemented and not many algorithms have been devised to break through them.
1.1 Background and Related work We refer to the security and usability problems involved with alphanumeric passwords as ‘‘the password problem.’’ The problem rises because passwords are expected to act with two conflicting requirements, namely: (1)Passwords should be easy to remember, and the authentication protocol should be executable quickly and easily by humans. (2) Passwords should be secure, i.e. they should be hard to guess and should look random; they should be changed frequently, and it should be different on different or multiple accounts of the same user; they should not be written down or stored in plain text. Meeting such requirements is almost impossible for users. The problem is well known in the security community. Classical studies going back over 25 years[5] have shown that, as a result, human users tend to choose and handle alphanumeric passwords insecurely. Recent studies confirm these results[6]. The password problem arises primarily from fundamental limitations of human’s long-term memory (LTM). Once a password has been chosen and learned the user must be able to remember and recall it to log in. However, people usually forget their passwords. The Power Law of Forgetting describes rapid forgetting soon after learning, followed by very slow drop-off thereafter[7]. Psychological theories have attributed forgetting to

1.INTRODUCTION [1]Computer, network, data and information security has been consider as a major technical problem faced nowadays. However, it is now widely recognized and accepted that most security mechanisms cannot succeed without taking into account the user’s views [2].Various graphical password schemes are used as alternatives to alphanumeric passwords [3]. Research has shown that alphanumeric passwords are filled with both security and usability problems that make them less than desirable solutions [4]. A key area in security research is authentication which deals with the determination of whether a particular user should be granted access to a given system or resource. This paper aims at providing understanding about a new graphical password authentication system using image segmentation. The significance of this study paper is the comprehension of a flexible graphical password © 2017, IRJET
