“…In digital watermarking, the watermark is a recognition cryptogram that takes information of the copyright owner. Watermarking is a significant technique in the region of information security [3][4][5][6][7][8][9][10][11][12]. It is one of the important techniques which are used for preservation the genesis of the image by defensive it against piracy [13][14][15][16][17][18].…”

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.

“…Due to swift maturation in internet technology, digital images being major class of multimedia, plays a vital role in communication systems. These images are characterized inimitably by high inter pixel redundancy, strong correlation between adjacent pixels and bulk data capacity [1][2][3][4][5][6][7].…”

<span lang="EN-US">In this article, a combined Pseudo Hadamard transformation and modified Bogdonav chaotic generator based image encryption technique is proposed. Pixel position transformation is performed using Pseudo Hadamard transformation and pixel value variation is made using Bogdonav chaotic substitution. Bogdonav chaotic generator produces random sequences and it is observed that very less correlation between the adjacent elements in the sequence. The cipher image obtained from the transformation stage is subjected for substitution using Bogdonav chaotic sequence to break correlation between adjacent pixels. The cipher image is subjected for various security tests under noisy conditions and very high degree of similarity is observed after deciphering process between original and decrypted images.</span>

“…Robustness and imperceptibility are the major parameters of a secured watermarking technique [12][13]. Robustness involves the ability of a watermarked image to withstand differential attacks such as cropping of watermarked image, filtering the watermarked image to reduce noise interference and compression of watermarked image to reduce the space for storage.…”

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.
