在线医疗初级诊断系统通过应用移动通信和数据分析技术，提供便捷的医疗决策支持，被认为是提高医疗服务质量的一种有前景的途径。然而，在用户健康信息的隐私性和诊断结果的准确性方面仍面临着许多严峻的挑战，这阻碍了在线医疗初级诊断系统的广泛采用。在本文中，我们提出了一个高效且隐私保护的在线医疗初级诊断（CINEMA）框架。在CINEMA框架下，用户可以在不泄露医疗数据的情况下，准确访问在线医疗初级诊断服务。具体而言，基于快速安全排列和比较技术，将加密后的用户查询直接在服务提供商（SP）处进行操作，无需解密，诊断结果只能由用户解密，同时也可以保护SP中的诊断模型。通过广泛的分析，我们发现CINEMA可以保证用户的健康信息和医疗保健SP的诊断模型的保密性，并且显著减少了计算和通信开销。此外，通过实施CINEMA进行的绩效评估证明了其在真实环境中的有效性。
Online medical primary diagnosis system, which can provide convenient medical decision support through applying mobile communication and data analysis technology, has been considered as a promising approach to improve the quality of healthcare service. However, it still faces many severe challenges on the privacy of users’ health information and the accuracy of diagnosis result, which deter the wide adoption of online medical primary diagnosis system. In this paper, we propose an efficient and privacy-preserving online medical primary diagnosis (CINEMA) framework. Within CINEMA framework, users can access online medical primary diagnosing service accurately without divulging their medical data. Specifically, based on fast secure permutation and comparison technique, the encrypted user’s query is directly operated at the service provider (SP) without decryption, and the diagnosis result can only be decrypted by the user, meanwhile, the diagnosis model in SP can also be protected. Through extensive analysis, we show that CINEMA can ensure that user’s health information and healthcare SP’s diagnosis model are kept confidential, and has significantly reduce computation and communication overhead. In addition, performance evaluations via implementing CINEMA demonstrate its effectiveness in term of the real environment.
