Abstract

Medical image security is a critical concern in the healthcare domain, and various watermarking techniques have been explored to embed imperceptible and secure data within medical images. This paper introduces an innovative frequency-based watermarking technique for medical images, utilizing the Fractional Discrete Cosine Transform (FDCT) and Schur decomposition to ensure robust and secure watermark embedding. The watermark bits are integrated by modulating the obtained Schur coefficients, thereby ensuring robust and secure watermarking without significantly altering the visual quality of the medical images. The experiments conducted on the ocular database demonstrate the capacity, imperceptibility, and robustness of the proposed method. This approach achieved a favorable trade-off between imperceptibility and information embedding capacity for ensuring the authenticity and integrity of medical images during transmission.

基于频率的医学图像安全和不可感知水印技术
医疗图像的安全性是医疗保健领域的一个关键问题,人们探索了各种水印技术,以在医疗图像中嵌入不易察觉的安全数据。本文介绍了一种创新的基于频率的医学图像水印技术,利用分数离散余弦变换(FDCT)和舒尔分解确保稳健安全的水印嵌入。通过调制获得的舒尔系数来整合水印比特,从而在不明显改变医学图像视觉质量的情况下确保水印的稳健性和安全性。在眼科数据库上进行的实验证明了所提出方法的容量、不可感知性和鲁棒性。这种方法在不可感知性和信息嵌入能力之间实现了良好的权衡,确保了医学图像在传输过程中的真实性和完整性。

期刊介绍: Rapid developments in the analog and digital processing of signals for communication, control, and computer systems have made the theory of electrical circuits and signal processing a burgeoning area of research and design. The aim of Circuits, Systems, and Signal Processing (CSSP) is to help meet the needs of outlets for significant research papers and state-of-the-art review articles in the area. The scope of the journal is broad, ranging from mathematical foundations to practical engineering design. It encompasses, but is not limited to, such topics as linear and nonlinear networks, distributed circuits and systems, multi-dimensional signals and systems, analog filters and signal processing, digital filters and signal processing, statistical signal processing, multimedia, computer aided design, graph theory, neural systems, communication circuits and systems, and VLSI signal processing. The Editorial Board is international, and papers are welcome from throughout the world. The journal is devoted primarily to research papers, but survey, expository, and tutorial papers are also published. Circuits, Systems, and Signal Processing (CSSP) is published twelve times annually.
