Image encryption is an effective approach for providing security and privacy protection for medical images. This paper introduces a new lossless approach, called EdgeCrypt, to encrypt medical images using the information contained within an edge map. The algorithm can fully protect the selected objects/regions within medical images or the entire medical images. It can also encrypt other types of images such as grayscale images or color images. The algorithm can be used for privacy protection in the real-time medical applications such as wireless medical networking and mobile medical services.
图像加密是为医学图像提供安全和隐私保护的有效方法。本文介绍了一种名为EdgeCrypt的新型无损方法，用于利用边缘图中包含的信息对医学图像进行加密。该算法可以充分保护医学图像中的选定对象/区域或整个医学图像。它还可以加密其他类型的图像，如灰度图像或彩色图像。该算法可用于无线医疗网络和移动医疗服务等实时医疗应用中的隐私保护。
