Efficiency and Security of Some Image Encryption Algorithms

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

5 shows input image and resultant encrypted images for different mapping images using proposed selective encryption based on sub-blocks.. From these resultant images we can

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

I ,TABLE.II, and TABLE.III, shows a large results of MSE which mean that the proposed key is successful in concealing the pure image information and a

The algorithm encryption and decryption of an image transform an image into cipher code using the random keys, which allow users to have confidentiality and security in

The cloud computing security based on fully Homomorphic encryption, is a new concept of security which enables providing results of calculations on encrypted
