Security • Easy identification of malicious data & user
• Data access management

FIG. 8.14
Benefits of blockchain technology.

Health claims: Insurance money, clinical data breaching compensations, wrong treatment penalty
etc. will be easy to recover. Disintermediation of third parties and trustless digital systems with smart
contracts by blockchain can easily ensure monetary gain for the victims.
Medication adherence: Patient behavior partially influences the medication integrity. Few pa-
tients are now well aware of the medicine, therapy, or diet plan given by doctors. Blockchain technol-
ogy can provide incentives after fulfilling any particular task or order by the physician. The smart
medical device can act in an interactive way to remind the patient about his do’s and don’ts. Blockchain
can introduce a medication smart contract between the IoT device and patient.

8.4.6 INTEROPERABILITY AND DATA SHARING
Research and development are all about the interconnectivity of the entities and data sharing. Data
includes OMICS, drug success rate, IoT device feedback, patient’s lab report, medication status etc.
All this information is shared among laboratories, businesses, researchers, patients, blood banks,
