Overview

Three-level image password authentication is a user authentication method that utilizes a combination of graphical images and alphanumeric passwords. It provides a more secure authentication process than traditional alphanumeric passwords while still being easy to remember. In this method, the user is first asked to select a set of images from a predefined image bank. The user then assigns an alphanumeric password to each image. To authenticate, the user is asked to recall the images and enter their corresponding passwords. This method is advantageous because it is both secure and easy to remember, since it only requires the user to remember the images and their passwords. Additionally, since the passwords are not stored in plaintext, the authentication process is more secure than traditional alphanumeric passwords.

Objective

The objective of a three-level image password authentication system is to provide increased security beyond a two-level authentication system. By adding a third layer of authentication, it allows for a more robust verification process and reduces the chances of unauthorized access. The three levels are usually a combination of passwords, personal identification numbers (PINs), and/or images. This system is also designed to help prevent fraud and identity theft. By requiring users to select an image to identify themselves and their account, it makes it much harder for someone to gain access without their permission. Additionally, the use of multiple levels of authentication helps to ensure that only authorized users can access sensitive information. This system provides an extra layer of security to help protect user data and reduce the risk of malicious activity.

Aim

The aim of three-level image password authentication is to provide an extra layer of security to online accounts and other digital assets. It is a method of authentication that requires a user to select images from a pool of images that are then sequentially arranged and used as a password. This system is designed to provide enhanced security by making it difficult for attackers to guess the correct sequence of images, as it requires knowledge of the images selected and their order. It also requires the user to remember the images used, thus making it more difficult for an attacker to guess the password. This authentication system is used in various online services such as banking, e-commerce, and other digital asset management systems. By using this system, users can protect their online accounts from unauthorized access and protect their digital assets from being stolen or misused.
