“…The Internet of Things refers to the use of sensing devices such as radio frequency identification systems or infrared induction systems to give objects intelligence according to a certain protocol and connect objects to the Internet through ports, thereby forming a distributed network of interconnected objects and realizing intelligent object identification, tracking, monitoring, and management technology [ 6 , 7 ]. It connects the object to the network through the information detection device according to the protocol, communicates through the media, and realizes the functions of intelligent identification, configuration, monitoring, and monitoring [ 8 ].…”

With the development of science and technology, more and more operations are performed in the cardiac catheterization laboratory. During such operations, a lot of relevant imaging data need to be retained. These imaging data can be used for clinical and scientific research and teaching applications, but imaging data security has also become an increasingly important issue. This article is based on the Internet of Things cardiac catheterization laboratory information management system image data security mechanism system research. First of all, this article adopts the literature method to study the application research of the Internet of Things technology in the medical field, as well as the relevant medical imaging data security technology methods. Then, the medical image data security mechanism was designed, and the image data security model of the cardiac catheterization laboratory information management system based on the Internet of Things was established. Finally, the application of decentralized management of the Internet of Things RFID technology on medical equipment and the security of the application of this technology on medical imaging data are analyzed, and finally a conclusion is drawn. The image data security mechanism established in this article is based on the Internet of Things technology. The security rate of image information data reaches more than 95%, the information data security level reaches level 1, and the average data missing rate is only 4.7%. It is a brand-new breakthrough, hoping to further improve the efficiency of hospital information management and protect the safety of medical information.

“…The embedding of zero watermarking was realized through the exclusive or (XOR) operation between the singular value of each block and the pixel value of the actual binary character watermark. [10] proposed a DWT and SVD-based scheme for digital watermarking. [11] proposed a blind scheme based on DWT, SVD and support vector regression.…”

A semi-blind watermarking scheme is presented based on Singular Value Decomposition (SVD), which makes essential use of the fact that, the SVD subspace preserves significant amount of information of an image and is a one way decomposition. The principal components are used, along with the corresponding singular vectors of the watermark image to watermark the target image. For further security, the semi-blind scheme is extended to an invisible hash based watermarking scheme. The hash based scheme commits a watermark with a key such that, it is incoherent with the actual watermark, and can only be extracted using the key. Its security is analyzed in the random oracle model and shown to be unforgeable, invisible and satisfying the property of non-repudiation.
