“…We use different sizes images, for example, to check the technique performance by testing encryption strength and original image recovery. The strength of encryption is been evaluated using two of the most common quantity; the number of pixel changing rate (NPCR) and the unified average changed intensity (UACI) [34][35]. Peak signal-to-noise ratio (PSNR) is used to test image quality.…”

Abstract-As the result of increasing use of internet in daily communication and the importance of information security during data storage and transmission process, we propose iterative Chaotic Genetic-fuzzy Encryption Technique(C-GET) in order to enhance secured encryption technique and less predictable. In this technique,binarize any digital data type. The main encryption stages of C-GET are chaotic map functions, fuzzy logic and genetic operations. Mathematic operations and rotation are also included that increase encryption quality. Images are used for testing propose. For testing C-GET,digitalimagesareusedbecause they become an important resource of communication. The original and reconstructed data are identical. Experimental results show that C-GET technique has multilayer protection stages against various attacks and a powerful security based on the multi-stages, multiple parameters, fuzzy logic and genetic operations. Decrypted data is nearly randomness and has negligible correlation with secret data.

“…The correlation coefficient (CC) is one of the important metrics to evaluate the security of scrambling method. It defines the degree of resemblance between two variables [32]. The image scrambling method is considered efficient if it can distort the data of the host image completely with the lowest correlation value.…”

“…CC between a host image and the encrypted image is equal to 1 and −1 for the inverse image. On the other hand, it is almost zero for a highly uncorrelated image [32]. CC between a host image and scrambled image can be calculated as…”

“…This indicates that the proposed scrambling method is more secure than other methods. The security of a scrambling method can also be measured using the number of pixel change rate (NPCR) and the universal average change intensity (UACI) tests [32]. NPCR means the number of pixels that change in the encrypted image when one pixel change occurs in the original image.…”

Copyright protection of multimedia content is confronted with great challenges such as easy access to the Internet. Digital watermarking is widely applicable technique for copyright protection of multimedia contents. In this paper, a blind symmetric watermarking method in canonical and cepstrum domains based on four-connected t-o'clock scrambling is proposed. Initially, the watermark image is scrambled using the four-connected t-o'clock method to enhance the security. Then, the rotation operation is applied to the host image to extract the region where the watermark bits are embedded. After that, discrete linear canonical transform (DLCT) is applied to the extracted region to obtain the DLCT region. Cepstrum transform (CT) is performed on DLCT region to attain CT region. The CT region is then divided into non-overlapping blocks. The watermark bits are inserted into each block using max-heap and min-heap tree property. Experimental results illustrate that the proposed method shows high robustness against numerous attacks. Moreover, it produces high quality watermarked images and provides high security. Furthermore, it has superior performance to recent methods in terms of imperceptibility, robustness, and security.

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.
