“…Among these characteristics, imperceptibility, robustness, and data capacity conflict with each other, this restricts the concrete implementation of the watermarking algorithm [4][5][6]. In order to obtain better robustness, the embedded watermark strength should be as high as possible, which affects the imperceptibility of the watermark.…”

Researchers in the fields of information security and computer image processing are deeply concerned about digital watermarking technology as piracy of digital products like images, audio, video, and files, which are becoming increasingly serious due to the Internet's rapid development and the media resources' digitalization. By detecting the watermark information embedded in the digital media to identify the media copyright, the copyright of the digital media can be effectively protected. In fact, digital watermarking has important application value in covert communication, bill anti-counterfeiting, digital signature, fingerprint identification, logo implicit authentication, and so on. In this paper, an algorithm-and algorithm-combination-based dual digital watermarking design technique is proposed. Based on a careful examination of the algorithms and algorithms one at a time, this creative proposal combines the two algorithms to achieve efficient embedding and extraction of digital watermarks and to take advantage of the double watermark's security benefits to encrypt the transmission of digital maps, thereby enhancing the security of image transmission. Then, the scheme is tested to prove its feasibility. At the same time, in order to verify the advantages of the scheme, a variety of attack experiments are carried out on the scheme, and the experimental data in the same environment are compared with other dual digital watermarking schemes. Finally, the superiority and robustness of the scheme are obtained, and it is applied and popularized in the military. The emphasis of this paper is to realize the information security of armored mechanized troops. During the battle, armored mechanized units use the positioning system equipped by armored vehicles to snap the geographical environment of the battlefield instantly, and upload the image to the rear combat command center in time through the network, military network, and people's network. In this long-distance transmission process, in order to ensure the security and timeliness of the transmitted images, it is necessary to use encryption technology to protect and verify the military images.

“…However, digital watermarking emerged in recent years [5] [6]. The main purpose of digital watermarking is for copyright protection, so that when pirated products emerge, content owners are able to extract some hidden information in the content to prove ownership of the content in a court of law [7].…”

Transmission of data over the internet has become a critical issue as a result of the advancement in technology, since it is possible for pirates to steal the intellectual property of content owners. This paper presents a new digital watermarking scheme that combines some operators of the Genetic Algorithm (GA) and the Residue Number (RN) System (RNS) to perform encryption on an image, which is embedded into a cover image for the purposes of watermarking. Thus, an image watermarking scheme uses an encrypted image. The secret image is embedded in decomposed frames of the cover image achieved by applying a three-level Discrete Wavelet Transform (DWT). This is to ensure that the secret information is not exposed even when there is a successful attack on the cover information. Content creators can prove ownership of the multimedia content by unveiling the secret information in a court of law. The proposed scheme was tested with sample data using MATLAB2022 and the results of the simulation show a great deal of imperceptibility and robustness as compared to similar existing schemes.

“…There are many kinds of watermarking, but visible watermarking technology offers a more active protection of digital material since it not only prevents pirates from stealing digital information, but it also visibly identifies the security of multimedia information. A visible watermarking technique should include content information to guarantee that security patterns are difficult to design, making it hard for unauthorized individuals to access watermarked material [5,6]. Due to the experienced assault, the extracted watermark may or may not match the pristine watermark.…”

Data hiding strategies have recently gained popularity in different fields; Digital watermark technology was developed for hiding copyright information in the image visually or invisibly. Today, 3D model technology has the potential to alter the field because it allows for the production of sophisticated structures and forms that were previously impossible to achieve. In this paper, a new watermarking method for the 3D model is presented. The proposed method is based on the geometrical and topology properties of the 3D model surface to increase the security. The geometrical properties are based on computing the mean curvature for a surface and topology based on the number of edges around each vertex, the vertices that have negative mean curvature and an odd number of edges around the vertex are selected for embedding. Selecting the vertex with negative mean curvature value means the vertex located in the deep region of the surface, so it not noticeable change to human eyes. To evaluate the performance of the proposed algorithm, the PSNR, and CF are used as a measurement to evaluate the visibility and robustness of the 3D watermarked model. The experimental results have shown the proposed algorithm has good imperceptibility where the PSNR reach up to 44.41 and robustness against attack where the CF is one in many cases.
