The traditional binary image is no longer sufficient to bring richer information in modern production and life. Color images have more information data than binary images. Based on the development of color image models and digital watermarking technology, this paper uses the Arnold scrambling and DWT-DCT method improves the robustness and invisibility of double color digital image watermarking. The encryption method improves the security of the watermark itself to a certain extent.

Multiphase flow measurements, based on tomographic imaging techniques, have made substantial progress in the past several years. In particular, ultrasonic tomographic reconstruction has shown its high potential in accurately measuring fluid fractions in a flow cross-section based on direct flow measurements. These types of measurements are very attractive as the system is nonradioactive, has direct contact to fluid, yet without flow obstruction. An ultrasonic tomographic multiphase flow meter (UTM) is being developed to capture the fluid flow rates and phase compositions in producing oil wells. The UTM aims to generate cross-sectional images of the flow inside the pipe. To recover these images, complex computations and high processing time are required, based on a limited amount of available data. For this purpose, compressive sensing (CS) reconstruction methods have shown great potential in overcoming the mentioned data quality and quantity issues. CS builds upon the fact that one can recover certain data of interest from potentially very few measurements. Many CS algorithms have been proposed in the literature. In this paper, we seek to find a suitable algorithm by comparing different CS algorithms in terms of the resulting recovered image quality. Specifically, we survey three algorithms in CS, namely basis pursuit, iterative soft thresholding (IST), and orthogonal matching pursuit (OMP). We also compare the results of the CS algorithms to that of a least-square based conventional algorithm. The numerical results show the superiority of CS recovery algorithms over the conventional approach, both qualitatively and quantitatively. The results also suggest that high image quality could potentially be achieved with less complex CS algorithms, i.e., the IST and OMP algorithms. As presented in the paper, our goal is to adapt CS reconstruction algorithms for images generated by the UTM, for the purpose of accurate quantification of oil, gas, and water phase fractions produced from different wells.

As an important means of information security and copyright protection, digital watermarking technology has been extensive researched and widely applied; it proves data’s ownership or integrity by embedding secret information into raw data, thus achieves the purpose of copyright protection and information security. Based on the analysis and research of wavelet transformation, this study achieves to embed digital watermarking into the oracle bone inscriptions rubbings. Experimental results show that this method has a stronger robustness to altering and cutting of images.

The vision of the Internet of Things (IoT) is that it connects all kinds of things by leveraging the creation of increasingly affordable and small devices that can be embedded for sensing, processing, wireless communication, and actuation. Named data networking (NDN) is a newly emerging Internet paradigm that may replace the current Internet architecture and that fulfills most of the expectations of the IoT. Software-defined networking (SDN) is an emerging paradigm of technology that is highly capable of managing overall networks efficiently and transforming complex network architectures into manageable, simple ones. The combination of the SDN controller, NDN, and IoT can be lethal in the overall performance of the network. Broadcast storms, due to the flooding nature of NDN’s wireless channel, are a serious issue when it comes to forwarding interest and data packets. Energy consumption of sensor nodes in dense IoT scenarios causes problems in forwarding as well as unnecessary delays, decreases network performance, and increases the cost and packet delay for important packets. We took these problems as our baseline and proposed an energy-efficient, priority-based forwarding (EPF) in SDN-enabled NDN–IoT. Our scheme EPF used the efficient flow management of the SDN controller to control the broadcast storm and efficiently forward the priority-based packets. A defer timer mechanism was used to prioritized the packet upon its arrival to the node. An energy threshold mechanism was used to control energy consumption and improve overall energy efficiency. We compared our scheme with the traditional flooding mechanism and geographic interest forwarding; EPF outclassed the other schemes and produced the best results in terms of total number of interests and retransmissions, content retrieval time, total number of priority interests, energy consumption, and network lifetime.

Combined with the biometric identification technology and digital watermarking technology, a digital watermarking algorithm based on iris features is proposed. A secret key is used to generate the pseudorandom sequence which would have the cryptography in the sense of security. Through the two-scale wavelet transform and the combination of singular value decomposition, the robustness of the watermark can be improved. The experimental result shows that the watermarking algorithm is fit for iris feature and has strong robustness in noise resistance, geometric transform, compression and other aspects.

With the rapid development of Generative Artificial Intelligence (AIGC) technology, the creation and dissemination of digital content have entered a new era. However, issues such as copyright protection, security, and traceability of these generated contents are gradually becoming prominent, and effective technological measures are still needed to address them. Digital watermarking technology, as an effective means to solve these problems, has a wide range of application prospects. This study proposes a new digital watermarking algorithm specifically targeting the characteristics of AIGC generated content, aiming to address the shortcomings of existing technologies in terms of concealment, robustness, and security. By comparing and analyzing existing technologies, improvement plans were proposed and optimized and experimentally verified. The experimental results show that the proposed algorithm can effectively improve the copyright protection capability of content while ensuring the concealment of watermarks, and has good application prospects.

We propose a method for preventing illegal re-recording of images and videos with digital camcorders. Conventional digital watermarking techniques involve embedding content ID into images and videos, which helps to identify the place and time where the actual content was recorded. However, digital watermarking technology does not control the illegal re-recording of digital content with camcorders. The proposed method prevents such re-recording by corrupting the recorded content with an invisible noise signal using CCD or CMOS devices during recording. In this way, the re-recorded content will be unusable. To validate the results of this proposed method, we developed a functional prototype system for preventing illegal re-recording and implemented it on a 100-inch cinema screen.

Digital watermarking technology is that directly embedded a number of landmark information into the multimedia content through a certain algorithm, which does not affect the value and use of original content, and can not be aware of the perception system or note. MPEG-4 of the video structure is analyzed in the paper, we propose a spread spectrum-based video digital watermarking to improve the program, and gives application examples.

In the current scenario, information transmission through digitize way is becoming a fast variant. But security between information transmissions is a measure concern. So digital watermarking technology provides a way for prevention of unauthorized access, distinguish information against illegal exploitations and allocations and copyright protection of the digitize data. Digital watermarking method should be robust, so it would be recoverable even if a part of this is altered. For embedding and extracting the watermark from the original image many different methods are provided. In this research paper watermarking is done by the combining the features of DWT (Discrete wavelet transformation) and Discrete Cosine Transformation (DCT). Red color component of the image is used for applying the DWT for embedding the watermark. After this, DCT is implemented on the 8×8 block of the image. Using this functionality a more secure and robust image is found

Commutative encryption and watermarking (CEW) is an emerging method that combines encryption technology with digital watermarking technology. It has the dual capability of secure transmission and copyright protection. However, the existing CEW methods for vector maps have good robustness in resisting geometric attacks but poor resistance to vertex attacks (e.g., addition, deletion, etc.). To solve this problem, here we propose a novel invariant-based CEW algorithm for vector maps, which consists of permutation-based encryption scheme and coordinates-based watermarking scheme. In the encryption scheme, the encryption key is generated via the Gaussian distribution method combined with the SHA-512 hash method; then, the double random position permutation strategy is applied to the vector map encryption. In watermarking embedding scheme, the original watermark image is scrambled via logistic chaotic encryption before embedding, and the coordinates of all the vertices are normalized. Then, the scrambled watermark image is embedded into the normalized coordinates. Results show that: proposed method is more robust to conventional attacks (e.g., vertex addition and deletion, reordering and data format conversion) and geometric attacks (e.g., scaling and translation). In addition, compared with the existing CEW methods for vector maps, the proposed method has higher security and stronger robustness against vertex attacks.
