Encryption and Decryption of Digital Image Using Color Signal

The position of the data is scrambled in the order of randomness of the elements obtained from the chaotic map and again rearranged back to their original position in

In this paper we have used capabilities and features of hyper chaos functions such as sensitivity to initial values, random behavior, non-periodic and certainty

Encryption is the process of converting a plaintext message into cipher text which can be decoded back into the original message using the secret key. An encryption/

An attacker can examine the histogram of an encrypted image (red, green and blue) using the algorithms of attack and the statistical analysis of the encrypted image

Cryptography or sometimes referred to as encipherment is used to convert the plaintext to encode or make unreadable form of text [1]. The sensitive data are

The entropy of the watermarked image and correlation coefficient of extracted watermark image is very close to ideal values, proving the correctness of proposed

Some algorithms are proposed according to the characteristics of the image itself, such as Yuen’s proposal of a chaos-based joint image compression and encryption algorithm

To perform the shuffling of the plain- image’s pixels, a block and stream based shuffling scheme is proposed, in which the plain- image is decomposed into 8x8
