数字水印技术是一种隐藏特定身份信息的版权认证技术。医学图像大多采用联合图像专家组（JPEG）标准进行压缩存储。水印在这里适于在JPEG压缩期间将患者信息与医学图像交织，以减少存储和传输开销。文本数据在与频域中的图像交织之前被加密，以确保更高的安全性。图形信号也与图像交错。这项工作的结果制成表格的一个具体的例子，并与空间域交织。(C)2004爱思唯尔爱尔兰有限公司保留所有权利。
Digital watermarking is a technique of hiding specific identification data for copyright authentication. Most of the medical images are compressed by joint photographic experts group (JPEG) standard for storage. The watermarking is adapted here for interleaving patient information with medical images during JPEG compression, to reduce storage and transmission overheads. The text data is encrypted before interleaving with images in the frequency domain to ensure greater security. The graphical signals are also interleaved with the image. The result of this work is tabulated for a specific example and also compared with the spatial domain interleaving. (C) 2004 Elsevier Ireland Ltd. All rights reserved.
