Smart and Digital Healthcare. Advanced technologies and security issues

Abstract

Smart and Digital healthcare is governed by ICT (Information and Communication Technology) and uses interconnected devices through communication networks to manage medical data, monitor patient status, manage hospitals and interact with government agencies. Multiple types of network architectures are used to be able to implement Digital Healthcare, some of them use the bottom-up approach, while others use the top-down approach. In Smart Healthcare, in addition to the advanced features of ICT, modern technologies such as IoT and sensors, Big Data and Data Mining, Deep Learning, Cloud Computing, Fog Computing and Edge Computing, Artificial Intelligence and Machine Learning are implemented. However, since the digitization process, the security challenges in Healthcare are also growing exponentially, so critical security threats can cause considerable damage, even threatening the lives of patients. The purpose of the scientific article is to create an overview of e-healthcare and s-healthcare practices and the security challenges they face, as well as to review the security technologies to be implemented, to traditional ones such as: encryption, access control, hashing, redundancy etc.; to advanced security technologies such as blockchain, artificial intelligence, cyber-physical system and quantum cryptography.
