The rapid development in the information technology field has introduced digital watermark technologies as a solution to prevent unauthorized copying and redistribution of data. This article introduces a self-embedded image verification and integrity scheme. The images are firstly split into dedicated segments of the same block sizes. Then, different Analytic Beta-Wavelet (ABW) orthogonal filters are utilized for embedding a self-segment watermark for image segment using a predefined method. ABW orthogonal filter coefficients are estimated to improve image reconstruction under different block sizes. We conduct a comparative study comparing the watermarked images using three kinds of ABW filters for block sizes 64 × 64, 128 × 128, and 256 × 256. We embed the watermark using the ABW-based image watermarking method in the 2-level middle frequency sub-bands of the ABW digital image coefficients. The imperceptibility and robustness of the ABW-based image watermarking method image is evaluated based on the Peak Signal to Noise Ratio (PSNR) and Correlation coefficient values. From the implementation results, we came to know that this ABW-based image watermarking method can withstand many image manipulations compared to other existing methods.

“…For instance, H(P c , S 2 ) can be used as a seed for a random number generator (RNG) and the RNG output determines the indices of theT bits placed in the least significant bit (LSB) of the image pixels. Another way is to use permutation maps such as the baker map [14] to scrambleT in the image and use H(P c , S 2 ) as the key of the map. The client finally sends the generated image along with S, S 1 and S 2 .…”

Powerful cryptographic systems based on mathematically hard problems are utilized to ensure tighter security for data communication purposes. However, these traditional cryptographic systems are bound to fail in the ensuing era of quantum computing. Thus, Artificial Intelligence (AI) inspired security methods are needed to secure communications in the era of quantum computing. This paper presents a challenge-response password-based authentication system based on the Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) AI hard problem. In this system, a server sends a challenge text to a client, then the client generates a random image and blends the challenge text inside this random image using his password. Then the client sends the generated image to the server. The server extracts the challenge text from the sent image using his copy of the client's password. If the extracted challenge text is the same as the sent challenge text, then both the client's and the server's copies of the password match and the client is authenticated. The efficiency of the proposed system is analyzed and the outcomes prove that the proposed system is efficient in terms of time and space. Also, a security investigation of the proposed system is employed, and the results prove that the system is probabilistic and very sensitive to changes in its parameters. It does not leak any statistical information about the client's password and the generated images cannot be distinguished from random images. In addition, the security of the proposed system is analyzed against two possible attacks; the brute force attack and the replay attack and the results prove that the proposed system is immune to these attacks. Finally, the proposed system is ensured to be indistinguishably secure against an adaptive chosen-challenge text attack (IND-ACCTA), based on the CAPTCHA AI hard problem when the hash function H is modeled as a random oracle.

“…While chaoticbased image encryption utilizes Shannon rules [12] that employ confusion-diffusion operations depending on non-linearity theorems [13][14][15][16]. Chaotic-based encryption schemes may be employed in spatial and frequency domains [17][18][19]. Chaotic functions offer several merits like their sensitivity to the initial conditions, which results in secure cryptographic systems against parameter perturbation.…”

“…Hence, chaotic-based encryption algorithms are being used recently in image cryptography systems [23][24][25][26][27]. In [17], a colored image encryption scheme based on utilizing the Discrete Cosine Transform (DCT) with a chaotic baker map was presented. First, the three-color image components are transformed to the frequency domain with the DCT.…”

This paper introduces an efficient image cryptography system. The proposed image cryptography system is based on employing the two-dimensional (2D) chaotic henon map (CHM) in the Discrete Fourier Transform (DFT). The proposed DFT-based CHM image cryptography has two procedures which are the encryption and decryption procedures. In the proposed DFT-based CHM image cryptography, the confusion is employed using the CHM while the diffusion is realized using the DFT. So, the proposed DFT-based CHM image cryptography achieves both confusion and diffusion characteristics. The encryption procedure starts by applying the DFT on the image then the DFT transformed image is scrambled using the CHM and the inverse DFT is applied to get the finally encrypted image. The decryption procedure follows the inverse procedure of encryption. The proposed DFT-based CHM image cryptography system is examined using a set of security tests like statistical tests, entropy tests, differential tests, and sensitivity tests. The obtained results confirm and ensure the superiority of the proposed DFT-based CHM image cryptography system. These outcomes encourage the employment of the proposed DFT-based CHM image cryptography system in real-time image and video applications.
