Nowadays, the administration of medical images can be compromised by several information security issues. Among others, a first problem consists in authenticating the source that originated the medical image and verifying that it corresponds to the correct patient; a second problem is aimed to avoid detachment between an electronic patient record and its corresponding images. A promising solution is the use of digital watermarking techniques applied to medical images considering in the design requirements of imperceptibility-robustness of the field of medical imaging. In this paper a digital watermarking method for an efficient administration of ultrasound images is proposed. To avoid the detachment between the record and images, we use an invisible watermarking in the frequency domain of the image. To authenticate the source of origin of the medical image, we use a visible-imperceptible watermarking in the spatial domain of the image. The experimental results show an efficient robustness and imperceptibility of the embedded watermark signals into the medical image. A comparison of performance with related works previously reported in the literature is included.

使用数字水印对超声图像进行有效管理

如今，医学图像的管理可能会受到一些信息安全问题的影响。其中，第一个问题在于验证产生医学图像的来源并验证它对应于正确的患者；第二个问题旨在避免电子病历与其相应图像之间的分离。考虑到医学成像领域的不可感知性-鲁棒性的设计要求，一个有前途的解决方案是将数字水印技术应用于医学图像。在本文中，提出了一种用于有效管理超声图像的数字水印方法。为了避免记录和图像之间的分离，我们在图像的频域中使用了不可见水印。为了验证医学图像的来源，我们在图像的空间域中使用了可见-不可察觉的水印。实验结果表明嵌入水印信号到医学图像中的有效鲁棒性和不可察觉性。包括与文献中先前报道的相关作品的性能比较。
