“…Singh et al [ 5 ] proposed a block-based DWT-SVD image watermarking approach where QR (quick response code) code is considered as a watermark image. Both the original image and watermark image are decomposed by 2-level DWT on a low-frequency band and the corresponding frequency band is separated into m × n block size.…”

Digital watermarking is playing a vital role in the improvement of authentication, security, and copyright protection in today’s digital transformation. The performance of this technique is shown to be impressive around the globe. Text, audio, video, and image data are acted as watermarks in the digital platform. In this article, a hybrid watermarking scheme is proposed to furnish the robustness and protection of digital data. This hybrid scheme is a form of discrete wavelet transform (DWT) and singular value decomposition (SVD). The embedding and extracting features are carried out through multi-level operations of DWT and SVD. Various attacks are added to the proposed method to justify the robustness of the watermark. In the end, the suggested approach is contrasted with existing methods to confirm the supremacy.

“…Unlike the spatial domain, frequency domain schemes generally enable more robustness against multiple attacks and make it more difficult for images to be perceived. This is because, in this scheme, the watermark is embedded within the original image's transformed coefficient by trading off imperceptibility [1]. Moreover, its computational capacity and data hiding ability are more than the spatial domain; hence, making it more preferable.…”

“…Moreover, it is an efficient mathematical tool that is optimum for the hierarchical decomposing of digital images. At each level, the decomposition of images takes place into four sub-brands: three high-frequency sub-brands, namely HH, LH, and HL, and one low-frequency sub-brand (LL) see Figure 1 [1]. The high-frequency parts are used for digital watermarking while the low-frequency part plays a critical role in the extraction of the watermark.…”

“…In the current digital world, transferring large chunks of data over the internet-via multiple hierarchies-has made it significantly difficult to protect and identify the ownership of digital media. Thus, the watermark technique has been introduced as a potential solution for copyright protection, authorization, identification, and ownership [1]. With the help of digital watermarking, a user can send his/her personal information on the internet without getting worried about its manipulation or disclosure, whether unintentionally or intentionally.…”

<span>Recent growth and development of internet and multimedia technologies have made it significant to upload data; however, in this situation, the protection of intellectual property rights has become a critical issue. Digital media, including videos, audios, and images are readily distributed, reproduced, and manipulated over these networks that will be lost copyright. Also, the development of various data manipulation tools like PDF converter and Photoshop Editor has resulted in digital data copyright issues. So, a digital watermarking technique has emerged as an efficient technique of protecting intellectual property rights by providing digital data copyright authentication and protection. In this technique, a watermarked document was integrated into electronic data to prevent unauthorized access. In this paper, A robust watermark algorithm based on a 5-level DWT and Two Log was proposed to enhance the copyright protection of images in unsecured media. Our lab results validate that our algorithm scheme is robust and forceful against several sets of attacks, and high quality watermarked image was achieved, where the algorithm was assessed by computation of many evaluation metrics such as PSNR, SNR, MAE, and RMSE.</span>

“…Studies have proven that it is difficult for counterfeiters, cybercriminals, and malicious actors to remove and alter watermarks. Therefore, this gives the owner of the information autonomy over their content as well as safety and security [6]. Counterfeiters also attack the digital content, thus degrading its quality, but it has been proven that attacking watermarked images or videos becomes very difficult, especially in recovering the watermark.…”
