电子健康记录 (EHR) 促进了医疗保健流程。然而，它也可能导致严重的安全和隐私问题。虽然各种传统的加密机制可以解决这些问题的某些方面，但它们无法解决解密医学图像的非法分发。为了保护解密的医学图像不被授权人员非法分发，本文提出的方案提供了一种基于GoL（生命游戏）和DNA计算的联合指纹和加密（JFE）方案，以保护医疗媒体分发。本研究分别使用GoL和DNA在DWT域中进行混淆，在空间域中进行扩散，并将指纹嵌入到DWT域的HL和LH子带中。使用指纹识别和加密可以为医学图像提供双层保护。实验结果表明了该方案的有效性。
Electronic health records (EHRs) facilitates the healthcare process. However, it can also cause serious security and privacy problems. While various conventional encryption mechanisms can solve some aspects of these problems, they cannot address the illegal distribution of decrypted medical images. To protect decrypted medical images from being illegally distributed by an authorized staff member, the scheme proposed in this paper provides a joint fingerprinting and encryption (JFE) scheme based on GoL (Game of Life) and DNA computing with the purpose of protecting medical media distribution. In this study, GoL and DNA are used to confuse in DWT domain and diffusion in spatial domain respectively, and fingerprints are embedded into the HL and LH subbands of DWT domain. The use of fingerprinting along with encryption can provide a double-layer of protection to medical image. Experimental results show the effectiveness of the proposed scheme.
