“…By the transform domain, various transformations such as DCT [11,12], DFT [13,14], DWT [15,16] and SVD [17,18] were mainly used to convert the original images into the frequency domain, and then inverted after embedding watermark. Compared with the spatial domain method, the transform domain methods could embed more information without destroying the value of the original images.…”

With the help of big data, cloud computing, artificial intelligence and other technologies, the informatization and intelligence of the wisdom medical have been gradually realized. However, with the transmission and storage of massive amounts of medical images in the cloud, information security issues have become increasingly prominent. The privacy of patients is at risk of disclosure, theft and tampering, which has become an important challenge restricting the development of wisdom medical. How to protect the personal information of patients in the cloud environment has become an urgent problem to be solved. Medical image watermarking technology is an effective method to solve this problem. Combining the characteristics of Tent chaos and Henon chaos, this paper designed a Tent-Henon-Map double chaos watermarking encryption method and designed a medical image encryption watermarking algorithm based on ridgelet-DCT transform. The watermark images were encrypted by the Tent-Henon-Map double chaos which had the characteristics of sensitive initial values and large key space. Then, the feature vectors of the medical images were extracted through ridgelet-DCT transform. On the basis of ordinary watermarking technology, combined with zero watermarking, third-party concepts, and cryptographic technology, watermarking had a good ability to resist image processing attacks. The experimental results showed that the key space of the algorithm was $${10}^{116}$$ 10 116 , which had better encryption and hard to crack. The time of watermark embedding and extraction were only 0.336 s and 0.439 s, with lower computational cost. And under high-strength conventional attacks and geometric attacks, the NC values of the algorithm were all greater than 0.55, which could effectively extract watermark information. It shown that the algorithm proposed had good robustness against conventional and geometric attacks It shown that the algorithm proposed had good robustness against conventional and geometric attacks, while taking into account the security.

In this digital era, the vast development of multimedia environments and information technology creates a need for protecting digital content from unauthorized access. Digital watermarking is a universally accepted technique for tackling the issues in the field of multimedia security and information rights management. Several appropriate image watermarking processes have been designed to secure the digital content. An efficient watermarking technique should maintain the tradeoff among imperceptibility, robustness, embedding capacity, and security. Primarily, this paper presents the classifications and applications of digital image watermarking techniques. The discussion comprises the spatial, transform, and hybrid image watermarking methods as well as its comparison with the different schemes. The contribution of this article will be beneficial to the academicians for gaining deep knowledge about image watermarking schemes.

“…Digital image watermarking techniques add a watermark into multimedia data to ensure authenticity and to protecting a copyright holder from the unauthorized manipulation of their data [12]. Hence, it is necessary to define the requirements or characteristics of a watermarking system, which are listed in the following subsections.…”

“…Their proposed method demonstrated better robustness in image authentication [78]. Another paper [12] introduced a method which was robust against JPEG compression along with a Gaussian low pass filter. This method embeds 4096 bits of information of an image whose dimension is 512 × 512 pixels, where adaptive quantization can be used to select the twelve representative DCT coefficients which embed the watermark.…”

Digital image authentication is an extremely significant concern for the digital revolution, as it is easy to tamper with any image. In the last few decades, it has been an urgent concern for researchers to ensure the authenticity of digital images. Based on the desired applications, several suitable watermarking techniques have been developed to mitigate this concern. However, it is tough to achieve a watermarking system that is simultaneously robust and secure. This paper gives details of standard watermarking system frameworks and lists some standard requirements that are used in designing watermarking techniques for several distinct applications. The current trends of digital image watermarking techniques are also reviewed in order to find the state-of-the-art methods and their limitations. Some conventional attacks are discussed, and future research directions are given.
