This really seems to be reaching to create a research paper. WHY?
Storing information of stroke rehabilitation patients using blockchain technology
Abstract
Background
Stroke patients usually experience damage
to multiple functions and a long rehabilitation period. Hence, there is a
large volume of patient clinical information. It thus takes a long time
for clinicians to identify the patient’s information and essential
pieces of information may be overlooked. To solve this, we stored the
essential clinical information of stroke patients in a blockchain and
implemented the blockchain technology using the Java programming
language.
Methods
We created a mini blockchain to store the medical information of patients using the Java programming language.
Results
After generating a unique pair of
public/private keys for identity verification, a patient’s identity is
verified by applying the Elliptic Curve Digital Signature Algorithm
based on the generated keys. When the identity verification is complete,
new medical data are stored in the transaction list and the generated
transaction is verified. When verification is completed normally, the
block hash value is derived using the transaction value and the hash
value of the previous block. The hash value of the previous block is
then stored in the generated block to interconnect the blocks.
Conclusion
We demonstrated that blockchain can be used
to store and deliver the patient information of stroke patients. It may
be difficult to directly implement the code that we developed in the
medical field, but it can serve as a starting point for the creation of a
blockchain system to be used in the field.

Introduction
A blockchain, also called a distributed or
shared ledger, is a technology through which participants jointly
verify, store, distribute, and interconnect data without an authorized
third party by generating data in blocks [1,2].
It allows participants to jointly record data by distributing the data
to a person-to-person (P2P) network rather than to the central server of
a specific organization [1,2].
Those who are permitted to see the ledger read it according to an
agreed method, and the transactions are also recorded according to an
agreed method. In this way, information can be stored securely without a
central server, and the content can be trusted without a third-party
guarantee. The applications of blockchain have been expanding to various
fields including government, finance, and public data, and its use is
also being explored in the medical field [3-5].
Currently, patient medical information is
stored on hospital servers, and hospitals cannot easily exchange the
patient information stored on such servers with other hospitals because
of the risk of a privacy breach [1].
Consequently, when patients are transferred to another hospital, they
need to carry their medical information from one hospital to the next.
Conversely, if blockchain were used in place of servers, the information
would be generated and recorded in block units and then stored on
multiple nodes in a distributed manner [6].
This would make hacking practically impossible while allowing hospitals
to easily and freely share patient information with other hospitals.
During the rehabilitation of a stroke
patient, a large amount of data related to the patient’s condition is
generated due to the long rehabilitation period [7].
Furthermore, many patients are transferred to different hospitals to
receive rehabilitation treatments. When a patient moves to another
hospital, the patient or their guardian must receive the printed patient
care information from the old hospital and deliver it to the new
hospital [1,7].
Doctors check the current and past conditions of transferred patients
based on these paper records, which takes a considerable amount of time.
Moreover, important pieces of information may be missed due to the
large volume of information and because each hospital records patient
information in its own way. We believe that blockchain can help to solve
this problem.

Based on the previous study [7],
we identified the essential information for stroke patients receiving
rehabilitation treatment and then used private blockchain network
technology to store the information of one patient through the medical
information transaction process. Since the personal medical information
of patients can be transferred on the network, only the participants who
were authorized to use the private blockchain were allowed to write and
read the patient medical information.
