Abstract-Recently, security of digital images has attracted significant attention. This paper evaluates the performance of authentication-encryption and confidentiality block cipher modes of operation, on digital image. Authentication-encryption scheme, such as Offset Code Book (OCB) mode, offers both privacy and authenticity; that is to say, this scheme provides data authenticity without increasing the cost of encryption. The performance of this mode is compared with other confidentiality modes of operation, such as the fast counter (CTR) mode that just encrypts the image without verification. Various statistical methods, such as correlation coefficient, Number of Pixels Change Rate (NPCR), and Unified Average Changing Intensity (UACI) are utilized to analyze the efficiency of different modes. Results show that the model based on OCB scheme, by both AES and Serpent algorithms, exhibits good performance on a digital image compared to the models based on other modes. OCB-AES based scheme, associated with its own authentication, has considerable speed in comparison with other confidentiality modes.

In this paper, we analyze a recently proposed semi-fragile watermarking scheme based on local binary pattern (LBP) operators, and note that it has a fundamental flaw in the design. In this work, a binary watermark is embedded into image blocks by modifying the neighborhood pixels according to the LBP pattern. However, different image blocks might have the same LBP pattern, which can lead to false detection in watermark extraction process. In other words, one can modify the host image intentionally without affecting its watermark message. In addition, there is no encryption process before watermark embedding, which brings another potential security problem. To illustrate its weakness, two special copy-paste attacks are proposed in this paper, and several experiments are conducted to prove the effectiveness of these attacks. To solve these problems, an improved semi-fragile watermarking based on LBP operators is presented. In watermark embedding process, the central pixel value of each block is taken into account and Arnold transform is adopted to guarantee the security of watermark. Experimental results show that the improved watermarking scheme can overcome the above defects and locate the tampered region effectively.

“…The general body of knowledge in the area of cryptography application and developing a cipher algorithm for image encryption of m*n size by shuffling the RGB pixel values has been discussed in [17]. A color image encryption algorithm has been designed by use of Arnold transform and discrete cosine transform (DCT) in [18]. A simple and practical color image encryption has been proposed with the help of quick response (QR) code in [19].…”

Nowadays, various types of attacks are imposed to multimedia during transmission. Also in many applications the security of information is very important. So the information encryption has become an important issue. Many encryption techniques have been proposed to achieve high robustness against different types of attacks and to save information from hackers. In this paper, a new chaotic based optical encryption that depends on Discrete Wavelet Transform (DWT) for image transformation will be introduced for color image encryption. Nine chaotic maps have been used in the proposed technique; eight of them were traditional and one is a new proposed map. As a result of extensive simulation results depending on various performance metrics it has been found that the proposed technique has given better robustness comparing to traditional algorithm.
