“…From table 1 it has been noticed that, an average of 99.6089% NPCR and 33.4328% UACI values are achieved which are greater than 99.5876% and 28.2474% respective values from the conventional PHT algorithm [4] due to effective shuffling of pixel values by MPHT compared to conventional PHT. The algorithm takes an average of 0.18 second for encryption process and is less than 0.29 second mentioned in modified Camellia algorithm [7], 1.27 seconds as mentioned in the hybrid chaotic map [8] to encrypt 256X256 images. Time of execution will be more for large sized images.…”

“…With the help of all these tactics, the unauthorized third party user tries to hack the information. If an efficient cryptographic algorithm withstands differential attacks, indirectly it resists analytical and brute force attacks [4][5][6][7][8]. Multimedia protection is done through various cryptographic algorithms since 1970s [9].…”

In this article, a Modified Pseudo Hadamard Transformation (MPHT) and non-Chaotic substitution based image encryption scheme has been proposed. Due to intrinsic properties such as, strong redundancy and correlation between the adjacent pixels, images are more vulnerable to cyber-attacks. In the proposed technique, the redundancy and correlation have been effectively reduced by pixel position transformation using MPHT and pixel value variation using non chaotic substitution, providing two stage security in encryption for secrete images. An average 99.6089% of Number of Pixel Changing Rate (NPCR) and 33.4328% of Unified Average pixel Changing Intensity (UACI) are obtained for a set of standard test images compared to more popular existing techniques

“…Digital image watermarking (DIW) is an extensively used mutual technique to code multimedia data with an identifier for the purpose of authentication between source and destination [1][2]. Thumping the unique information by a deceptive (cipher) is the foremost feature of information security [3][4][5][6][7]. Digital watermarking can be a very effective tool for information hiding as it is a process of hiding information inside a digital signal [8].…”

In this paper, exponential transformation based watermarking of multimedia images has been proposed. The principle behind the scheme is anticipated in frequency domain to elevate robustness and big data entrenching capacity. In the anticipated approach, the secrete image is first imperiled for compression using exponential function and then entrenched onto the cover data. Statistical analysis of resultant data proves better robustness in par with other existing methodologies.

Abstract: In this article, an exponential transformation based digital image watermarking scheme has been described. The method is employed with 12 th root of exponential function for embedding watermark into the cover image. Due to bulk data capacity of the image, many watermarking techniques uses more time for data insertion and separation processes. Algorithm is designed in such a way to embed a watermark of 1/16 th size of host. The retrieved watermark is examined under various security analysis. Many standard test images are subjected for watermarking process under proposed scheme resulted with better scale and utilizes less computational time compared to other techniques.
