1.1 Introduction
Folder Locker Application is a system that restricts unauthorized access to an individual's financial, health, private, and confidential information. Presently used password based systems have a number of associated inconveniences and problems such as user needs to remember passwords, passwords can be guessed or broken down via brute force and also there is problem of non-repudiation. Image password seems to be a better way out.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitations of the Study and Definition of technical terms.
1.2 Background of Study
The increasing threat to computer system and the information they store and process are valuable resources which need to be protected. Authentication refers to the techniques where users have to prove the claim of their identity to the identifier. There are many techniques through which users can be authenticated. Some of the password authentication techniques are knowledge based, token based, and biometric. Text password based technique and graphical password based technique comes under knowledge based authentication technique. A text password is a secret word or string of character that is used for user authentication to proven identity or for access approval to gain access to a resource. The easier a password is for the owner to remember generally means it will be easier for an attacker to guess.
However, passwords which are difficult to remember may also reduce the security of a system because user might need to write down or electronically store the password, users will need frequent password resets and users are more likely to re-use same password. Unfortunately, these passwords are broken mercilessly by intruders by several simple means such as masquerading, Eaves dropping and other rude means say dictionary attacks, shoulder surfing attacks, social engineering attacks (Wikipedia, 2021). A graphical based password is one promising alternatives of textual passwords, as according to human psychology, humans brain can recall or memories the visual thing in a well manner than text (Wikipedia, 2021). In graphical password based technique sequence of images are uses which are more memorable than sequence of characters. There are many graphical based password scheme is available. Of interest herein are cued-recall click-based graphical passwords. Example systems include passpoint, cued click points and persuasive cued click points. The guessing attacks capture attack, and hotspot problems reduce the security of passpoints and cued click points (Wikipedia, 2021). To overcome this we are trying to implement persuasive cued click points technique that is here we are using image password for authentication and security and we are also implementing SHA for encrypting the folder to provide more security to folder. The paper is structured as follow. We discuss about graphical password technique, persuasive cued click point, methodology, modules description, application, security and conclusion.
When using services in a web environment, security is of great importance especially for both the user and the provider. The information in use must be handled in a way that does not compromise its security. Passwords are only secured as long as the user keeps them secret. Not everyone is aware of the risk that comes with compromised passwords and other security leaks (Nilsson, 2012).
1.3 Statement of Problem
Providing security to the folder is most challenging job for the developers to be developed which will neither access or decrypted by the crackers. An information seeker tends to handle a system and searches all the system folders seeking for information from the system which can be used by them. Friends have turn out to be more of a treat than a friend, because the fact that you gave them access to your system, they explore it and made away with your vital credentials on the system. Therefore, the challenge of creating a folder locker need arise, and creating one with a secure and reliable source of authentication.
1.4 Aim and Objectives of the Study
The aim of the study is to develop a Folder Locker Application for Windows OS using C#.net. In achieving this aim, the following specific objectives were laid out as follows:
- To develop a secure system folder locker
- To build a new algorithm for the security model of the folder locker application.
- To create a windows application for securing any folder with its contents, by setting a pass key for accessing that folder.
- The new system design will be an image authentication system and an alternative of alphanumeric character set.
1.5 Significance of Study
This research work is significance to its core of objectives and achievements. This work well enhance the security level of ones privacy on his system. It will be a one-step project to the level at which information is high jack from the hackers. The research will also be beneficial to the researcher. This is because the study will expose the researcher to so many related areas in the course of carrying out his research. This will enhance the researcher’s experience, knowledge and understanding on real live application and solution solving techniques.
1.6 Scope of Study
The study focuses on the Folder Locker Application for Windows OS using C#.Net. This research work is centered on system application for security validation of folder access control and its content. Therefore, this study will work out only for the application which is a folder locker using an image model or alphanumeric pass key for validation means or authentication.
1.7 Limitations of the Study
During the course of this study, many things militated against its completion, some of which are:
- Time Constraint: The time frame given to accomplish this project was very short due to school academic calendar and it was carried out under pressure which made the researcher not to implement some necessary features.
- Research material: availability of research material is a major setback to the scope of the study.
- Frequent power failure: This made the researcher append more money on fuel to ensure sustainable power.
- Financial Constraint: Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet).
1.8 Definition of Terms
Encryption: is the process of encoding messages or information in such a way that only authorized parties can read it.
Decryption: The process of decoding data that has been encrypted into a secret format. Decryption requires a secret key or password.
Lock: a mechanical device used to secure items of importance.
A password: is a word or string of characters used for user authentication to prove identity or access approval to gain access to a resource (example: an access code is a type of password), which is to be kept secret from those not allowed access.
Authentication: is a process in which the credentials provided are compared to those on file in a database of authorized users’ information on a local operating system or within an authentication server.
Validation: is act of confirming that a user details meets the needs of its users
Software: These are program for computer which allows certain specific task to be accomplished e.g. word process etc.
Hardware: Computer equipment used to perform input processing and system output activates.
