“…From Figure 11, it is visualized that the proposed method and Su et al 23 have highest NC values (1.0) for all extracted watermarks and hence outperforms the method of Chou and Wu 21 . The columns of Figure 11 show extracted watermarks from considered watermarked images and first three rows show the extraction of RTU logo while last three show extraction of aeroplane image using the proposed and considered methods of watermarking.…”

“…As per our best knowledge this is the first inline work to use the UCS along with ABC for effective color image watermarking method. The performance of the proposed method has been measured in terms of quality and robustness against different signal processing attacks and results are compared with the work of Chou and Wu 21 and Su et al 23 . The results validate that the proposed method is bet- ter than other methods for all the considered parameters except slight decay in JPEG compression and rotation attacks as compared to Su et al 23 .…”

The exponential growth in electronic data over internet have increased the demand of a robust and high quality watermarking method for authentication and copyright protection. In general, the existing digital image watermarking methods embed the binary or gray scale watermark into the host image although most multimedia images are available in color. Moreover, available digital image watermarking methods generally use the correlated color spaces which impose the limitations to researchers for using only one color component at a time for embedding the watermark. Therefore, in this paper, a novel discrete wavelet transform (DWT) based color image watermarking method has been proposed which embeds the color watermark into host image using uncorrelated color space (UCS) and artificial bee colony (ABC) method. The results show that proposed method outperforms other existing methods against the various signal processing attacks.

In this paper, a spatial domain‐based blind watermarking scheme of color images integrating multilevel discrete Hartley transform (DHT) is proposed to protect color digital images' copyright under the current 5G network environment. On the basis of the unique spatial computing property of the maximum energy coefficient of DHT and the energy aggregation principle of multilevel image transform, the color watermark image scrambled by Affine transform is directly hidden into color carrier image by quantitative techniques in the spatial domain, rather than the complex DHT domain. The specific performance of the scheme in various aspects is as follows: (1) the average value of the peak signal‐to‐noise ratio is higher than 40 dB; (2) the average value of structural similarity index metric remains above 0.9700; (3) the average value of normalized cross‐correlation under no attack is 1.0000; (4) the average value of normalized cross‐correlation. under attack is above 0.9600; (5) the total execution time is 1.1856 s; (6) the maximum embedding capacity is 0.0625 bpp; and (7) the entire key space is greater than 2432. Multiple simulation results demonstrate that the proposed scheme is not merely imperceptible and robust, but also secure and efficient, which can protect the digital copyright with effect.

Multimedia evolution in the current era has given digital images security and privacy a great concern. Digital image watermarking is used to produce highly protected images in order to promote secure and protected exchange over the network and between individuals. In this paper, a robust algorithm for digital image watermarking is proposed based on a hybrid watermarking and auto‐thresholding. This algorithm is designed to embed the watermarks in the transform domain using both discrete cosine transform and discrete wavelet transform (DCT‐DWT). Image is transformed to DCT then to DWT and the algorithm trains itself to choose the best embedding threshold. This threshold must satisfy a performance trade‐off and at the same time attains high imperceptibility and robustness. The algorithm performance is evaluated under various attacks and showed high‐performance level. Imperceptibility evaluation showed peak signal‐to‐noise ratio above 42.96 dB and similarity percentage above 99.27%. The algorithm proved high resistance to noising, scaling, cropping, rotation, and compression attacks. Copyright © 2015 John Wiley & Sons, Ltd.
