“…Here the ABC algorithm was accomplished for the optimization of watermarking constant but the convergence of ABC is observed to be more. To achieve higher resistance over image processing attacks, a hybrid method was proposed in [13] based on DWT, FFT and SVD. Though this approach achieves good results for image processing attacks, this is not robust for geometric attacks like cropping, rescaling etc.…”

This paper proposes a Secure, robust and intelligent watermarking approach based on Redundant Wavelet Transform, Singular Value Decomposition and Genetic Algorithm. Here the robustness. The proposed watermarking scheme accomplishes RWT and SVD for feature extraction and the GA for optimization. Further this approach proposes a signature embedding mechanism by which the watermarked image will be more secure. The Genetic Algorithm proposed in this approach adopts intelligent property and the signature process adopts more security. Further the combination of RWT and SVD adopts the robustness to the proposed approach. Numerous experiments are conducted over the proposed approach and the performance is evaluated through the performance metrics such as Peak Signal to Noise ratio (PSNR) and Normalized Correlation (NC). The obtained experimental results demonstrates that the proposed approach is superior compared to conventional approach and is able to provide efficient resistance over Gaussian noise, salt & pepper noise, median filtering, cropping, rotation, contrast enhancement, scaling and Histogram Equalization attacks.

“…Bu yöntem ile orijinal görüntüden çıkarılan özellik, gizli anahtar ve damga birlikte kullanılarak gizli bir paylaşım oluşturulmuştur. Tiwari ve arkadaşları ADD, Hızlı Fourier Dönüşümü ve TDA işlemlerini birlikte kullanarak melez sayısal damgalama yöntemi sunmuşlardır [41]. Bu yöntemde önce orijinal görüntüye 3. seviye ADD işlemi uygulanmıştır.…”

Özet-Son yıllarda internet ve mobil teknolojilerin gelişmesi ile birlikte, çoklu-ortam dokümanlarının telif hakkının korunması önem kazanmıştır. Sayısal görüntü ve video gibi çoklu-ortam dokümanlarının korunmasında sayısal damgalama en çok kullanılan yöntem olmuştur. Bu çalışmada, Ayrık Kosinüs Dönüşümü, Ayrık Dalgacık Dönüşümü (ADD) ve Arnold Dönüşümü kullanılarak gri-seviyeli görüntü damgalama yöntemi önerilmiştir. Bu damgalama yönteminde eklenecek damgalar dört eşit parçalara ayrılmıştır. Saldırılara karşı damgalama yönteminin dayanıklılığını artırmak için bu parçaların her biri damga eklenecek görüntülerin ADD işlemi sonucunda elde edilen dört ayrı bantlarının farklı alt bölgelerine gizlenmiştir. ADD frekans uzayında farklı alt bölgelere damga ekleme işleminde önerilen griseviyeli damgalama yönteminin başarımı damgalanmış görüntülere doğrusal ve doğrusal olmayan saldırılar uygulanarak değerlendirilmiştir. Bu çalışmada ayrıca önerilen yöntem ile temel alçak frekans bandına damga ekleme yöntemi karşılaştırılmıştır. Deneysel sonuçlar önerilen yöntemin saldırılara karşı dayanıklı olduğunu göstermiştir. Bununla birlikte damgalanmış görüntülerin kalitelerinin korunduğu da görülmüştür.Abstract-Due to the development of the internet and mobile technologies in recent years, the protection of the copyright of multimedia documents has become importance. Digital watermarking is the most widely used method for protecting multimedia documents such as digital image and video. In this study, gray-level image watermarking method is proposed using Discrete Cosine Transform, Discrete Wavelet Transform (DWT) and Arnold Transform. In this watermarking method, the watermarks to be embedded are segmented into four equal-sized parts. In order to increase the robustness of watermarking method against the attacks, each one of these parts have been embedded inside different sub-regions of the four separate bands that have been obtained as a result of DWT processing of the cover images. The performance of the proposed gray-level watermarking method for embedding watermarks in different sub regions in DWT frequency domain has been evaluated by applying linear and nonlinear attacks to the watermarked images. Also, in this study the proposed method is compared with the basic low frequency band watermarking method. Experimental results have shown that the proposed method is robust to the attacks. It is also observed that the quality of the watermarked images has been preserved.

“…As an effective way to protect the information security, digital watermarking technology arises at the historic moment. The digital watermark technology is a digital protection technology for the purpose of secret transmission, storage and identification; it has become one of the hottest research topics in information security community (Thanh and Tanaka, 2016;Wang et al, 2016;Papakostas et al, 2014;Hu and Hsu, 2017;Sawant and Patil, 2017;Tiwari et al, 2017;.…”

The fractional wavelet transform (FRWT) is a generation of WT associated with the convolution theorem in fractional Fourier transform (FRFT) domain. The FRWT not only inherits the advantages of multi-resolution analysis of the wavelet transform (WT), but also has the capability of image representations in the FRFT domain. In view of the above characteristics, a novel digital image watermarking method based on FRWT and SVD is proposed in this paper. The experimental results show that this method is robust to geometric attacks and image processing attack.
