[Retracted] Analysis of Privacy-Preserving Edge Computing and Internet of Things Models in Healthcare Domain

Table 1

Privacy-preserving solutions in IoT-based healthcare and the associated challenges.

Privacy-preserving IoT-based healthcare solutions	References	Challenges
Quantum level computations SIMD-SHE	[21]	Dependence on other platforms (cloud computing)
Complete or partial use of blockchain	[4]	Need excessive computation resources
Data encryption schemes	[15, 22]	Low computation resources and high latency
Cryptography mechanisms	[15, 28] [29]	Limited resources
Data pseudonymization and anonymization schemes	[30–32]	Low bandwidth and network performance, absence of legal framework
Secure authentication scheme (SAB-UAS)	[33]	Low latency and network performance with high cost
