Table 1:
A summary of the reviewed blockchain systems in healthcare.
| Name | Use | Key Features |
|---|---|---|
| Health application | Mobile application | -developed for cognitive behavioral therapy for insomnia |
| -patient records own data and healthcare provider can access this data within minutes | ||
| Healthcare Data Gateway | Mobile application | -uses a simple unified indicator-centric schema (ICS) to organize data and a secure multi-party computing (MPC) system |
| Not named, Griggs et al. model | Remote monitoring | -sends secure real-time notifications to patients and healthcare providers via sensors that interact with smart devices which use smart contracts |
| Logitboost | Boosting algorithm | -can detect root exploit, a type of mobile malware that can destroy mobile health applications, at a rate of 93% accuracy |
| -can predict root exploit in a simulated root exploit detection system | ||
| MedBlock | Electronic medical record (EMR) access system | -improved consensus mechanism ensures that network is not overloaded |
| Blockchain based data preservation system (DPS) | Storing medical data | -prototype modeled after Ethereum system has been tested |
| OmniPHR | Patient health records (PHR) access and storage system | -places all patient health data into one accessible forum |
| -incorporates different patient datasets into different blocks on the chain | ||
| Not named, Wang and Song model | Electronic health record (EHR) storage and access system | -uses attribute-based encryption (ABE), identity-based encryption (IBE), and identity-based signatures (IBS) to create a type of cryptography called combined-attribute-based/identity-based encryption and signature (C-AB-/IB-ES) that maximizes security |
| Blockchain-based secure and privacy-preserving patient health information sharing (BSPP) scheme | Sharing of health data | -uses private blockchain for patient data and semi-private/consensus blockchain for non-sensitive, activity data |
| Not named, Dubovitskaya et al. model | Electronic medical record (EMR) sharing system | -developed for cancer patients |
| -lowers access time for records | ||
| Not named, Mamoshina et al. model | Sharing of health data | -uses LifePound, a digital currency that can buy and sell biomedical data |
| Blockchain-based multi-level privacy preserving location sharing (BMPLS) scheme | Sharing of health data | -enables sharing of patient location |
| -proposed for telecare medical information systems | ||
| MIStore | Medical insurance storage system | -uses different hospital, patient, and insurance servers that verify each other’s activity for security |
