Abstract
1. In today’s technologically advanced era, there are existing applications are using text passwords which are difficult to memorize.
2. This project aims is to implement a Strong Security application. The key feature of the application is that it uses image as a password which makes it more memorable.
3. The app uses an algorithm based on Image segmentation. The algorithm aims to remove the problems that occur while using the original algorithm.
Objective
To create a strong ,memorable security password using image segmentation to secure sensitive data

Design 2 Data flow Diagram
Design 3Algorithm
Programming lang Used : HTML5 Canvas , PHP , JavaScript , and CSS 1. Create Image Block Class to store properties( i,.e x ,y coordinates ,
block selected or not ) of each segments.
2. To Jumble image , we created SetImageBlock function . Using random XtoY (int i, int x ,int y) we changed the coordinate of the Imgage Block .
3. SetImageBlock function also checks how many blocks are right position
4. To drag Image . We registered the event mouse up , down , left and right
Problem Analysis
1. Predictable Image
