The entire healthcare system has experienced a transition from the conventional hospitalization model to a decentralized patient-oriented model; hence the evolving 5G network is supposed to support healthcare systems by significantly addressing various concerns in the healthcare sector such as AI-based surgeries, remote consultancies, etc. Healthcare sector is expected to expand at a rapid pace, the future Smart Healthcare systems may demand networks with more bandwidth, latency, etc. With the introduction of sensor-based intelligent healthcare applications, the demand for high-speed connectivity shall arise for linking many devices and appliances. 5G communication networks are combined with IoT devices to increase coverage of the network and reduce security concerns. As the healthcare systems shall be connected to internet & network-enabled devices in 5G networks, they shall fall under the category of cyber-physical systems and thus, they would be highly vulnerable to cyber-attacks. Various other problems of existing healthcare systems are - a complex network of system intermediaries, an increase in the cost of drug recovery & lack of transaction traceability that can be resolved using blockchain technology. Blockchain fosters decentralized, open, persistent, comprehensive, and safe architectural techniques. The inclusive perspective of Blockchain-based healthcare model shall offer services such as efficient access & storage of personal clinical as well as genetic data management, inventory management & supply chain management system, medical research related records, digital health cards & wallets, transparency, secure and hassle-free transactions, personalized medical treatment & care etc. This paper deals with the incorporation of Blockchain in the 5G healthcare sector and discusses its role in dealing with security and privacy concerns.
