Due to the rapid advancement in information technology, individuals as well as organizations frequently transfer or share their digital content via cyberspace. The security and integrity of this digital content become a big concern, as any middleman can misuse or temper this content. Digital watermarking is a blessing to protect it from any unwanted tampering. Even though many researchers have implemented various watermarking approaches, but still ownership protection and reliability concerns are not fully mitigated. This paper proposes an improved novel hybrid watermarking scheme by combining discrete wavelet transform (DWT) with singular value decomposition (SVD) to minimize these concerns. At first, the host image is decomposed by multi‐level DWT and a two‐level SVD is applied to the fourth lower‐level coefficient (LL5) of the host image. Then the watermark is inserted into the specified sub‐band of the host image. The watermark is extracted in a reverse manner. The hybridization of DWT and SVD ensures that the watermarking technique performs better in terms of visual distortion and robustness. The outcomes of the experiment show that our proposed method is more robust, imperceptible, and secure than the existing DWT‐SVD based methods, even with a broad watermark scale.

At present, digital image is the most significant information carrier on the Internet, which provides convenience for people to exchange information. With the progress of image processing theory, digital image inpainting technology has also developed rapidly. It not only enhances the image expression but also provides tools for image forgery. Misusing the tools may trigger a crisis of trust in the image. To eliminate the negative impact of image forgery, many scholars have conducted in-depth research on it and proposed a series of detection methods called image forensics for institutions or communities to identify such forged images. Current forensic technology still has many limitations, such as relying on specific features and data distribution which makes forensic technology lag behind image inpainting technology. So far, academia still lacks a unified understanding of image forgery and detection technology, and the research architecture of inpainting and forensic technology is not clear. This article reviews the development of image inpainting and forensic technology and systematically summarizes and scientifically classifies the current research work. Finally, the forensic technology is summarized and the future research direction is prospected to guide subsequent scholars to further promote the progress of image forensic technology.

Behind the popularity of multimedia technology, the dispute over image copyright is getting worse. In the digital watermark prevention technology for copyright infringement, watermark technology is considered to be an important technology to overcome data protection problems and verify the relationship between data ownership. Among the many digital watermarking technologies, zero watermarking technology has been favored in recent years. However, the existing zero watermark technology in the implementation process often needs a trusted third party to store watermarks, which may make the data too central, data storage security is low and copyright registration costs are too high, which creates a rare problem. The decentivization and information cannot be tampered of blockchain technology's nature find new methods for image copyright protection. This paper studies the role of zero watermark algorithm in the image copyright and its complete storage and certification scheme, proposes a zero watermark image protection framework based on blockchain, and builds a system according to the framework. Combined with blockchain and zero watermarking technology, the framework uses inter IPFS (Inter Planetary File System) to solve the problem of blockchain efficient storage and sharing of large files. In addition, the application of user copyright information, image image query and image trading in the system are realized based on smart contracts, which solves the problem of lack of trusted third parties. Experiments show that the scheme is feasible and robust to various attacks.
