Secure Telemedicine Providing Computer-Aided Diagnosis: A Systematic Review and Analysis

Despite the global telemedicine market’s significant growth from USD 27.04 Billion in 2019 to an anticipated USD 171.81 Billion by 2026, challenges such as secure data transfer, interoperability,data storage, integrity, cost, and complexity persist. In this manuscript, a structured and systematic review of techniques used to implement secure telemedicine is carried out.The main aim of this manuscript is to acquire knowledge about the latest technologies or researches which are used in the domain of telemedicine to make it more robust and secure. To the best of our knowledge, bifurcation based on security goals is carried out for the first time in the domain of telemedicine. We systematically classify and summarize existing research on techniques for achieving five key security goals: Authentication, Data Confidentiality, Authorization, Data Integrity, and Data Storage. Each category is further subdivided based on the applied techniques. Research gaps have been identified in the current state of the art and future steps to secure medical data and to achieve data integrity by following a pursuit of Cloud Storage and Blockchain network have been suggested.This comprehensive survey seeks to thoroughly investigate many scientific concepts, state-of- the-art, and innovative methodologies and implementations.
