In this paper, four kinds of chaos mapping equations such as Logistic, Henon, Quadratic and MacKeyGlass were discussed, and the numerical characteristics of those chaos mapping equations were analyzed and compared by histogram and correlation coefficient. Then the better chaos encryption system was selected according to analyzing result, and the encryption method of poor chaos encryption system...

Only combining encryption with fingerprinting together can provide comprehensive content security protection for visual media. Joint fingerprinting and decryption (JFD) framework solves encryption and fingerprinting simultaneously and has high efficiency, but several problems still remain to be tackled in JFD, including poor encryption security, severe fingerprinted image distortion, etc. An im...

The security of digital images attracts much attention recently, and many different image encryption methods have been proposed. In 1999, J.-C. Yen and J.-I. Guo proposed a novel image encryption algorithm called BRIE (Bit Recirculation Image Encryption). This paper points out that BRIE is not secure enough from strict cryptographic viewpoint. It has been found that some defects exist in BRIE, ...

Reversible (lossless) data embedding (hiding) has drawn lots of interest recently. Being reversible, the original cover content can be completely restored. This paper proposes a novel reversible data hiding scheme with a lower computational complexity and can be used in applications where both the image and the hidden information is highly confidential. It consists of three phases –AES image en...

Secret communication techniques are of great demand since last 3000 years due to the need of information security and confidentiality at various levels of communication such as while communicating confidential personal data , patients’ medical data, countries’ defence and intelligence information, data related to examinations etc. With advancements in image processing research, Image encryption...

Information security is the key in the era of electronic data exchange. Images constitute a large portion of the electronic data. Confidentiality of color images is a difficult process. Most of the image encryption algorithms are complex and compromise on the quality of the image. This paper proposes a new image encryption based on random pixel permutation with the motivation to maintain the qu...

The wide use of digital images leads to the necessity of securing them when they enter into an insecure channel. Image cryptography plays a vital role in the modern communication. In this paper we propose a new image encryption scaling scheme, which will do both, image scaling and encryption. Cellular automata is used for key generation and wavelet transformation is used for image scaling. Encr...

This paper proposed a new algorithm for digital image encryption. The proposed algorithm encrypts an mxn size image by using the set of array pixel values. At the end, plain images will be encrypted using the algorithm and analysis will be performed on the ciphered images to determine the efficiency of the algorithm in ciphering the image. The algorithm ultimately makes it possible for encrypti...
