From trustworthy data to trustworthy IoT: a data collection methodology based on blockchain [21] | A data collection method based on blockchain-IoT is proposed for creating a trustworthy environment. A hyperledger fabric-enabled smart contract is designed and implemented to balance trust and privacy during the process of collection. | (i) Preprocessing issue (ii) Hybrid and complex systems’ computational limitations (iii) Micro provider (iv) Data similarity-related challenges | (i) Hyperledger fabric (ii) Hash encryption (SHA-256) (iii) Permissioned, private network |
MedSBA: a novel and secure scheme to share medical data based on blockchain technology and attribute-based encryption [22] | The authors of MedSBA presented a secure and efficient blockchain-enabled share medical records and attribute-based encryption system proposed to record and store medical data. This proposed system protects patients’ privacy and allows fine-grain access control of medical services in the e-healthcare environment. | (i) PBFT consensus method (ii) Hybrid blockchain (iii) Communication and security related protocols issue (IoT/edge-enabled protocol) (iv) Patient’s device registration limitation | (i) General data protection regulation (ii) Private blockchain (iii) OPNET software tool used (iv) BAN logic |
A blockchain-based scheme for privacy-preserving and secure sharing of medical data [23] | The authors of this paper presented a blockchain-enabled privacy preservation scheme that enabled the secure exchange of sensitive medical information between participating stakeholders in a semitrusted cloud server. In addition, this proposed system achieves data availability between stakeholders where zero-authentication proof is employed. | (i) Hybrid communication channel (ii) Two-way authentication (iii) Cloud storage used | (i) Proxy-reencryption (ii) PBFT algorithm for transactions delivery and acknowledgement (iii) Zero-knowledge proof mechanism |
Medical data sharing scheme based on attribute cryptosystem and blockchain technology [24] | A medical data sharing model based on attribute-hash-encrypted and blockchain is proposed. In this paper, the data is validated first and then preserved on an efficient storage medium (distributed). And so, reduce the possibility of irreversible modification. For this reason, the authors designed a many-to-many communication mechanism for sharing sensitive medical data between stakeholders. | (i) Data duplication issue (ii) ABS protocol (iii) Identity privacy for preservation (iv) Chosen cypher-text attack | (i) Attribute-based signature (ii) Attribute-based encryption (iii) Many-to-many communication channel |
Design of a Secure Medical Data Sharing Scheme Based on Blockchain [25] | The authors of this paper proposed a blockchain-enabled authentication process for a network model of a medical cyber-physical system. This model is designed to ensure the data cannot be forged, tampered with, or untrackable. | (i) Sharing of medical big data (ii) Credibility problem (iii) Intractable challenges (iv) Bilinear mapping | (i) BAN logic (ii) Two-way authentication (iii) Permissionless network (iv) Consortium chain (v) Formal verification authentication |
MEdge-chain: leveraging edge computing and blockchain for efficient medical data exchange [26] | The authors of this paper proposed a medical-ledger blockchain- (MEdge-chain-) enabled holistic framework for exploiting the integration to aggregate diverse healthcare entities. Such medical entities’ scheduled processes of storage are, for example, swift first, then secure sharing, and lastly, preservation. | (i) Optimal blockchain configuration (ii) Data priority assignment challenge (iii) Limited resources (iv) Connectivity issue (v) Local healthcare service provider management (vi) Monitoring a large number of patients | (i) Delegated proof-of-stake consensus (ii) Edge-based remote monitoring (iii) Efficient data discovery (iv) Permissionless blockchain public network |
