Image Encryption using Chaos theory

This project deals with the encryption and decryption of the image using two logistic equation which is iterated in a loop at a certain number of times to genearte distinct value.The generated distinct value is used in key generatioan where it is further used in operations like XORing with the pixels.

A separate Image analyzer tool is provided to do avarious kinds of analysis on the image. Analysis like NPCR(Number Of Pixels Changed Rate),UACI(Unified Average Changed Intensity),Correlation coefficient ,RMSE(Root Mean Square Error) ,Histogram are integrated in this software .

Prerequisites

Notes:

• Allowed image formats are .jpeg and .png. User can select any of the mentioned image format.

• User can use their own secret key to encrypt and decrypt the image.

• Encryption and decryption time of the image depends on the size and resolution of the image.

• This project also analyzes the encrypted and original images.
