Abstract: Blockchain technology, which was first made famous by cryptocurrencies, has now attracted a lot of interest

from many different sectors, one of which is healthcare. Examining the potential benefits and drawbacks of

blockchain technology, this article delves into its experimental uses in the healthcare industry. After providing

a brief overview of blockchain technology, this paper explores its potential applications in healthcare,

specifically looking at how it can improve data security, interoperability, and patient empowerment. It also

tackles some of the challenges associated with blockchain technology, such as regulation, scalability, and

privacy. The healthcare business has become more efficient, leading to better patient safety, higher healthcare

expenses, and easier access to healthcare services. This study delves into various computing paradigms, data

processing techniques, and Internet of Things (IoT) architectures. In order to address its numerous healthcare

initiatives and their global advantages, it incorporates a number of communication technologies, often worn

sensors, and healthcare monitoring systems. This study also identifies potential future healthcare facility and

technology implementation strategies, examines the most prevalent problems with wearable sensory systems

that aid in healthcare monitoring, and suggests solutions. This method works well in small towns and rural

areas where doctors' offices can keep in touch with larger hospitals about their patients' health issues.

Nonetheless, should the patient's health deviate from the expected range, the healthcare monitoring system

will promptly alert the attending physician. Healthcare institutions benefit from blockchain technology's

increasing use to connect data storage facilities and secure data transfer by addressing the problem of data

duplication.

1 INTRODUCTION

One of the most prominent communication

paradigms, the Internet of things (IoT) is rapidly

expanding across many industries and offers the

prospect of centralized data access and fusion. Data

access permissions may be defined by user and per

authorized staff (e.g., healthcare medics and doctors)

(Lokesh Lodha, et al., 2020), (Soubhagya Ranjan

Mallick, et al., 2024) and (SoonHyeong Jeong, et al.,

2021). Concerns about privacy and confidentiality

make this limited access a must in the healthcare

industry. The Internet of Things (IoT) enables the

interconnection of various devices, such as sensors,

cars, homes, and appliances, over the Internet. This

enables the sharing of data, information, and

resources among users. The result is data fusion,

which has the potential to greatly improve application

usability, accessibility, and data analysis. Many new

trends have emerged as a result of the adaptability of

the Internet of Things (IoT), which aims to increase

data accessibility, resource efficiency, and data

communication across sources in order to boost data

integrity performance generally. Recent

developments in protocol communication

technologies, the prevalence of the Internet, and the

ease with which users may access and use the

underlying infrastructure have made this a reality.

Consequently, people are increasingly looking for

ways to save time and effort through centralized data

collecting and monitoring. Some significant areas

that have been embraced by the Internet of Things

(IoT) are smart cities, smart homes, healthcare, and

environmental monitoring. One of the most talked-

about issues recently is healthcare, which has risen to

prominence due to factors such as the fast

urbanization, industrialization, and aging populations

in European countries (Pratima Sharma, et al.,2023),

(WAFAA A. N. A. AL-NBHANY, et al., 2024) and

(Lokesh Lodha, et al 2024). Wireless body area

networks (WBANs) link separate nodes such as

sensors and actuators that are embedded in, on, or

beneath a person's skin (Simeon Okechukwu Ajakwe,

et al., 2024) and (Partha Pratim Ray, et al., 2021).

Typically, the network covers the entire human body

and is linked by a wireless communication connection

between the nodes. The implementation specifies a

star or multihop topology for these nodes to be placed

in.

Because of a WBAN's limitless range, various

exciting new uses have emerged in fields as diverse

as medicine, sports, home health care, multimedia,

and remote health monitoring. Wearable wireless

body area network (BAN) sensors can continuously

monitor a patient's vital signs in the medical industry,

including temperature, respiration rate, blood

pressure, heart rate, electrocardiogram (ECG), and

more. Some alternative therapies will enable the

patient to leave the hospital and enjoy fresh air inside

the room or even outside. It will help the hospital's

purse and the patient. The information accumulated

by the patients throughout the years in the natural

environment will give much more data useful for

quick and correct diagnosis (Anichur Rahman, et al.,

2024) and (Yazeed Yasin Ghadi, et al., 2024).

• IoT for Healthcare: Before the advent of

the Internet of Things, patients were limited

to contacting their doctors via home

visitations, via phone, or through text. There

was no way a healthcare provider or a

clinician could monitor the vital signs of a

patient all the time and give advice based on

such observations. Devices enabled by the

Internet of Things (IoT) have enabled

remote monitoring in healthcare, which has

the ability to keep patients safe and healthy

and gives doctors the ability to provide

exceptional care. Because interacting with

clinicians is now easier and faster, it has also

enhanced patient involvement and

happiness. Additionally, re-admissions are

reduced and hospital stays are shortened by

remote monitoring of patients' health.

Improving treatment results and drastically

lowering healthcare costs are two other areas

where the Internet of Things has a big

influence. By re-imagining the role of

devices and human interaction in healthcare

solution delivery, the Internet of Things

(IoT) is undeniably revolutionizing the

healthcare business. Everyone from patients

and their families to doctors, hospitals, and

insurance companies may reap the benefits

of the Internet of Things (IoT) in healthcare.

• IoT for Patients: Personalization of

treatment is made possible by the use of

wirelessly linked medical devices such as

glucometers, blood pressure monitors, heart

rate monitors, etc., in conjunction with

wearable fitness bands. A person's calorie

intake, exercise routine, appointment

scheduling, blood pressure fluctuations, and

a whole lot more may be programmed into

these gadgets. The ability to continuously

monitor health problems is one way in which

the Internet of Things has improved people's

lives, particularly for the elderly. People

who live alone and their families are greatly

affected by this. An alert mechanism

notifies worried family members and

healthcare providers if there is a disruption

or change in a person's usual activities.

• IoT for Physicians: With the help of

wearables and other IoT home monitoring

devices, medical practitioners may be able to

keep a closer eye on their patients' health. If

patients are adhering to their treatment plans

or if they need immediate medical attention,

they can be tracked by these systems. The

Internet of Things has the potential to make

healthcare practitioners more watchful by

allowing them to proactively engage with

patients. Doctors may use the data collected

by internet of things devices to help their

patients get the best treatment possible.

• IoT for Hospitals: Hospitals may greatly

benefit from IoT devices in many other ways

outside patient health monitoring. Internet

of Things (IoT) devices with sensors can

track medical equipment including oxygen

pumps, defibrillators, nebulizers, and

wheelchairs in real time. Additionally, it is

also feasible to monitor the deployment of

medical workers to different locations in

real-time. The spread of illnesses is a

reasonable concern for hospitalized patients.

Internet of Things (IoT) enabled hygiene

monitoring devices help reduce patient

infections. In addition to assisting with asset

management tasks like pharmaceutical

inventory control, IoT devices may monitor

and regulate environmental factors like

temperature and humidity.

• IoT for Health Insurance Companies:

When it comes to intelligent gadgets that are

linked to the Internet of Things, health

insurers have a lot of chances. Health

monitoring gadgets can help insurance firms

with underwriting and claims processes by

collecting data. They can use this

information to spot accusations of fraud and

find potential underwriters. With the use of

IoT devices, insurers and policyholders may

see each other's underwriting, pricing,

claims, and risk assessment procedures in

action. Customers will be able to see the

reasoning behind every decision and the

results of every process thanks to data-

driven decisions made in all operational

processes that are captured by the IoT. To

encourage the use and sharing of health data

provided by IoT devices, insurers may

provide incentives to policyholders. The IoT

features a four-stage design that may be

thought of as process steps. Data is gathered

or processed at one level and then passed on

to the next, with a direct correlation between

the four processes. The incorporation of

values into the process yields intuitive

understandings and exciting new

opportunities for businesses.

• Deploying a network of linked devices, such

as sensors, actuators, monitors, detectors,

video systems, etc. Gathered by these

gadgets is the data.

• We get data in analog form from sensors and

other devices. Then, we need to convert it to

digital form so we can process it further.

• After data is gathered and digitized, the third

step is to preprocess it, standardize it, and

then transfer it to a data center or the Cloud.

• Complete data management and analysis at

the desired level. The use of Advanced

Analytics to this data yields valuable

business insights that can be used to make

smart decisions.

2 RELATED WORKS

Increased privacy and security measures are required

by the healthcare business to comply with legislation

and safeguard sensitive patient information (Sireejaa

Uppal, et al.,2023). Blockchain technology allows

for the incorporation of both of these aspects into the

current systems. A swift solution to the problem of

user-friendliness can be achieved by combining

blockchain technology with the Internet of Things

(IoT). Devices built on the Internet of Things (IoT)

get beyond the low processing power of individual

smart health monitors. There is a storage capacity

constraint for cloud-assisted Internet of Things

devices, such as wearable sensors. It should be

considered, though, that this method is not without its

flaws, which cause it to be inefficient. Data sharing

and data privacy are two of these issues. A solution

based on the Interplanetary File System (IPFS) is

proposed in this study to address these issues. Here,

nodes belonging to other users—doctors,

pharmacists, insurance firms, hospital administrators,

etc are able to access the health data that individuals

continuously upload from their IoT devices and

include in blockchain transactions. Along with this

capability, users may perform transactions on

HealthDote's six blockchains using the system-

specific cryptocurrency DoteCoins to purchase

medical consultations, medicines, insurance authority

payments, and hospital supplies.

With the growth of the IoT, health monitoring

systems have also progressed. This paper focuses on

a four-layer health monitoring system that collects

patient information and provides input to several

medical classifications (Poonam Rani, et al., 2022) as

a secure architecture, providing support from IoT.

When data are collected for computation from

wearable smart sensing devices, the patient ever has

to be considered in both respect of privacy and

security. A lightweight and secure communication

protocol over decentralized IoT networks based on

blockchain architecture is developed as the prime

focus of this communication. The aim is to categorize

these networks into separate classes through transfer

learning. For data integrity, we present a system that

utilizes transfer learning through various pre-trained

models to bind itself with blockchain technology.

Energy consumption reduction and network traffic

minimization have been achieved through a routing

approach that prudently applies node energy,

credibility scores, and link reliability in deciding the

optimal route for data transmission. Classification

accuracy of 92.24% is achieved by the suggested

method, according to the findings.

Technology has allowed the eHealth sector to

expand rapidly, shifting focus away from traditional

hospital settings and toward providing care to patients

in the comfort of their own homes (Aya H. Allam, et

al., 2024). Remote patient monitoring, simplified

electronic medical record (EMR) administration,

medication traceability, and efficient disease control

are just a few of the ways that blockchain and the IoT

are improving healthcare services. This is especially

true in times of crisis, like the recent COVID-19

pandemic. Security issues, such as worries about data

integrity and device authentication, arise from the

increasing use of IoT devices. As a strong option, this

study suggests integrating blockchain technology.

Building trust among varied IoT devices, blockchain

uses its decentralized and tamper-resistant properties

to guarantee the integrity of IoT data. The final part

of this summarizes the issues posed by and potential

solutions offered to the eHealth IoT implementations

regarding blockchain technology. With the results of

this extensive survey, stakeholders will be better

equipped to make decisions that will improve patient

care in an ever-changing industry.

In modern domains including smart cities, smart

homes, schools, hospitals, transportation, and

military operations, the Internet of Things (IoT) plays

a pivotal role (Suliman Abdulmalek, et al., 2022).

When it comes to healthcare, IoT applications really

shine since they allow for safe, real-time remote

patient monitoring, which greatly enhances people's

lives. This article examines the ways in which

healthcare monitoring systems are being impacted by

the IoT. In addition to characterizing healthcare

monitoring sensors, the article delves into Internet of

Things (IoT) monitoring systems that rely on wireless

and wearable sensors. We also go into depth on the

difficulties and unresolved concerns related to

healthcare privacy and security, as well as quality of

service. At last, the study concludes with future

directions connected to several current technological

advances as well as proposals and recommendations

for healthcare IoT applications.

A growing number of entities, including

healthcare institutions, patients, insurance

companies, Internet of Medical Things sensor nodes,

and Internet of Things (IoT) wearable medical

devices, are becoming integral parts of IoMT systems

(Hamed Taherdoost 2023). Because of the need of

scalability in blockchain technology, designing a

blockchain for such applications is challenging. In

light of this insight, we set out to conduct an

exhaustive analysis of all English-language

blockchain-based IoMT solutions created between

2017 and 2022. Bringing together the theoretical

underpinnings of a large corpus of work published in

highly regarded academic journals over the past

decade, this research aims to standardize evaluation

approaches and fully capture the rapidly developing

blockchain area. The mentioned findings support the

identification of several research gaps and possible

future study directions that may benefit both

academics and practitioners.

3 METHODOLOGY

Health protection via prevention and prediction is

progressively replacing conventional medicine's

emphasis on therapy following diagnosis (p2 Health).

In response to this trend, it is essential to continuously

and comprehensively monitor parameters across all

healthcare domains using real-time monitoring and

individual data records. The health care internet of

things is the focal point of this new age of healthcare,

following the successful implementation of e-health

and m-health. Internet of Things (IoT) healthcare

platforms may integrate and combine (on the server

level) important parameters from several domains

which could help with healthcare security. The

second healthcare-related field is environmental

factor monitoring, which encompasses chemical and

physical components as well as vital signs and

physiological parameters. Using this platform, end-

users (approved staff) may alter sampling rates,

synchronize, monitor parameters on Wearables and

applications, and install additional sensor nodes. The

combination of sensor layers at the physical level and

data fusion on the cloud allows for ubiquitous and

centralized data processing, which is used in

healthcare and safety surveillance.

Remote and in-person patient monitoring,

diagnosis, and treatment have all been greatly

enhanced by the fast integration of technology in the

health sector in the past several years. Patients'

quality of life and the capacity to track their data are

both enhanced by this. Most of the injuries

considered focused on chronic illness monitoring as

the primary reason for the use of tele-medical

electrocardiogram systems and the top objective of

remote vital signs monitoring. This is a crucial step in

creating an all-inclusive solution for sequential

patient monitoring, regardless of the ailment, type of

check, or number of units to be managed. Whenever

a medical emergency occurs, the doctor is notified by

a preexisting wireless patient monitoring system that

includes a PIR sensor, temperature, humidity, and

smoke detectors that are attached to the patient's

body. Patient health monitoring network based on

Zigbee wireless sensors. This system is designed to

monitor elderly individuals and patients in coma.

Among its many sensors are those for measuring

heart rate, temperature, saline level, and micro-

electromechanical systems (MEMS). These IoT

systems, among others, provide great advantages to

health and medical care in terms of perception,

transfer, and action of data. IoT addressable parts that

emulate smart, accessible, and communicative

systems, for example, non-limiting is medical

equipment, patient information management and

medication control, telemedicine, mobile medical

care, personal health management, and many more.

In modern times, a number of portable sensor

devices have come up to monitor health, fitness, and

levels of activity-a good kind of tech as this

technology has started getting attention over the last

few years. Besides serving the specialized

recreational fitness domain catered by these devices,

researchers have investigated possibilities for their

clinical applications in tele-health monitoring

systems for long-term record-keeping, management,

and clinical access to patients' physiological data.

Every Internet-connected device in the Internet of

Things (IoT) network may communicate with any

other device in the network, and each device can be

uniquely identified and addressed at any moment.

Internet of Things (IoT) based remote health

monitoring systems may automatically exchange data

with healthcare facilities via the web. The following

Figure 1 shows the proposed approach block diagram

in clear manner.

• Create an Internet of Things (IoT) based

system that can efficiently measure

environmental, physiological, and behavioral

(partially) variables using a wearable

mechanism;

• Integrate, calibrate, and analyze

environmental and physiological factors in

order to conduct medical research on the

interplay between these variables. Also

included in this is the ability to see data on the

server.

• Launch and refine a modern ambient

monitoring prototype.

• The goal is to create an adaptable Internet of

Things gateway that can use various

commercial devices to measure physiological

indicators. Patients and consumers with a

variety of product ownership may all benefit

from this solution, and the platform is open to

all suppliers.

Figure 1: Block Diagram.

• The user and the medics may communicate in

real-time from beginning to conclusion,

allowing the medics to provide the user with

the advice they need.

• Determine a way to make it work for all types

of workers. By utilizing the end-to-end

connection and adaptable IoT-gateway,

medical professionals are granted the ability to

personalize each patient's monitoring

parameters, including the ability to activate or

deactivate certain sensors and parameters.

• Arduino Nano Microcontroller: Arduino is

a free and open-source software-based

platform for making prototypes. Engineers

may experiment with developing interactive

worlds using this versatile basis. Embedded

systems that can control and detect parameters

in real-time can be created using them,

depending on the application's programming.

It is composed of an ATmega328

microcontroller that can be programmed with

the Arduino software. An Arduino Uno Boot

loader is standard on the Arduino R3/Genuino

R3, which is the board's Indian counterpart.

When written with the Arduino IDE, it

simulates the behavior of the Arduino board.

There are a total of 20 digital inputs and

outputs (I/Os), 16 milliseconds (MHz) of

crystal oscillation, a USB connector, an ICSP

header, a reset button, and 14 digital inputs

and outputs (I/Os), 6 of which may function as

pulse width modulation (PWM) outputs. The

following Figure 2 shows the Arduino nano

microcontroller.

Figure 2: Arduino Nano Microcontroller.

Figure 3: Heartbeat Sensor.

• Heartbeat Sensor: Placing a finger on the

Heart Beat Sensor causes it to produce an

analogue signal that corresponds to the heart

rate. Upon activation, the heart detector will

begin to flash the topmost LED in response to

each heartbeat. In order to measure the heart

rate, the output of this sensor may be directly

linked to the microcontroller. It works on the

premise that light may be modulated by the

constant flow of blood via the finger's nerves

with each pulse. The analog output mode,

which is the module's default, is

straightforward. The following Figure 3 shows

the heartbeat sensor.

• Humidity Sensor: Humidity refers to the

amount of water vapor in the air. Many

industrial processes are sensitive to the

relative humidity of the air, which in turn

affects human comfort. Water vapor affects

many biological, chemical, and physical

processes as well. Because it may have an

impact on product costs and worker safety,

humidity monitoring is essential in industrial

settings. Control systems for industrial

operations and human comfort rely heavily on

humidity sensing. Many industrial and

household applications place a premium on

controlling or monitoring humidity. The

semiconductor industry is ever so reliant on

the measurement and control of relative

humidity and moisture in the fabrication of

wafers. An example of a medical application

of humidity management is pharmaceutical

manufacture, the production of biological

products, sterilizers, incubators, and

respiratory equipment. Some of the most vital

activities involving control of humidity

include dryers and ovens, chemical

purification of gas, humidity control, paper

and textile production, food processing, and

film drying. In agriculture, there are several

reasons for monitoring humidity, including

dew prevention in the plantings and soil

moisture regulation. Humidity management is

essential for residential applications such as

building interiors, microwave ovens, and other

kitchen appliances. To indicate the relative

humidity of a given area, humidity sensors are

used in all of these and countless more

applications. The following Figure 4 shows

the humidity sensor.

• MQ-6 Gas Sensor: The MQ-6 gas sensor is

designed using SnO2, which has relatively

low conductivity in clean air, as its sensitive

material. With the presence of the target

flammable gas, the conductivity of the sensor

follows the gas concentration. The change in

the conductivity would then be transformed

into an output signal by means of a basic

electronic circuit in order to determine the

concentration. This sensor has extremely high

sensitivity for gases such as natural gas,

butane, propane, and LPG. The sensor is

understood to be a useful product because of

its ability to detect various combustible gases,

including methane, while being versatile and

of low cost. The MQ-6 gas detector is shown

in Figure 5.

Figure 5: MQ-6 Gas Sensor.

• LM35 Temperature Sensor: The ability to

detect when an object is hot or cold is the

primary function of a temperature sensor.

With a proportional output to the temperature

(in °C), the LM35 is a precise integrated

circuit temperature sensor. The LM35 is a

more precise temperature sensor than a

thermistor.

Figure 6: LM35 Temperature Sensor.

Additionally, it has a low coefficient of

thermal expansion and raises the temperature

of still air by no more than 0.1 °C. The

temperature range in which it can function is -

55°C to 150°C. Because of its linear output,

low output impedance, and accurate intrinsic

calibration, the LM35 is ideal for use in

control or readout circuits. An output voltage

proportional to temperature in Celsius is

provided by the LM35. .01V/°C is the scaling

factor. The following Figure 6 shows the

LM35 temperature sensor.

• LCD Display: The liquid crystal display

(LCD) screen is an electrical display module

that has several functions. Many different

kinds of gadgets and circuits make use of the

same basic module: a 16x2 LCD display. This

LCD is called a 16x2 because it has two lines

of sixteen characters each. A 5x7 pixel matrix

displays each character in this LCD.

Command and Data are the names of the two

registers on this LCD. Figure 7 Shows the

LCD Display.

BlockChain and IoT Interfacing:

Blockchain technology is enhancing security,

privacy, and efficiency, skidding giant wheels

in revolutionizing healthcare monitoring. It

provides a decentralized and impossible to

penetrate system for conducting medical data

managements, integrity of data, and

functioning for real-time patient monitoring.

However, some challenges persist, including

privacy, interoperability, and security of data.

Blockchain technology, by providing smart

decentralized immutable frameworks, solves

all these problems in terms of IoT health

monitoring concerning its efficiency, privacy,

and security concerning real-time patient data.

COMMUNICATION, AND COMPUTING TECHNOLOGIES

334

With continuous health data stream from IoT

devices such as smart sensors, medical

implants, and wearables to be stored in the

blockchain, integrity is restored and

minimized access to the information outside

authorized parties. This integration creates

better interoperability, promotes data-sharing

among healthcare providers, and reduces the

chance of central data breaches. Not only does

blockchain technology allow early detection

of diseases and preventive health measures,

but also real-time health monitoring. While

blockchain-based IoT healthcare solutions

promise a safer, more transparent and efficient

digital healthcare ecosystem, they are also

faced with the immense cost of installation,

limited scalability, and regulatory compliance.

4 RESULTS AND DISCUSSION

Recent developments in healthcare monitoring

technology make it possible for medical equipment to

do real-time assessments hitherto unthinkable for

doctors to execute. It has also enabled healthcare

institutions to operate the lowest cost and

simultaneously service a bigger population. Big data

and cloud computing have also helped to increase

consistency and simplicity of doctor-patient

communication. This resulted in a decreased financial

burden for the patient and more patient participation

in the treatment process. Management has evolved

healthcare monitoring system applications including

personal care for children, old patients and illness

detection. Recent years' notable Internet of Things

effect helps to keep track of chronic illnesses and

enhance health and fitness by means of monitoring.

By tackling a broad spectrum of medical problems,

ideas and service have distorted the healthcare

industry. Growing health-care requirements and

technological developments drive daily service

provision from additional angles. An electronic

healthcare network depends on data interchange

between several medical devices and healthcare

service providers. Block chain technology is one of

the main issues with safe data also promoting

cooperation, sharing, and data fragmentation

nevertheless. Data fragmentation might cause a

knowledge gap between doctors linked to the same

patient. Lack of proper information might hinder the

course of therapy. Block chain technology not only

solves data fragmentation but also helps healthcare

institutions to link the data repositories found in the

network study.

Artificial Intelligence (AI), which interacts with

the Internet of Things, offers age-related support in

expert capacity. The main objective of the suggested

artificial intelligence-based solution is to let elderly

people live comfortably and safely at home. In the

event of a medical calamity, this system offers a

means for closely monitoring patients in real-time and

guarantees that they get help on par with those of

human services. Sophisticated artificial intelligence

techniques, large data analysis, machine learning, and

healthcare sector application help to make this

achievable. Several software tools, like MATLAB

and Arduino IDE, help to empirically evaluate the

suggested method. This MATLAB program is used to

link the whole hardware to PC and obtain the

necessary health data from patients via sensors

thereby enabling the Internet of Things (IoT) help.

MATLAB analyzes and handles the gathered data;

the results are shown to users appropriately. After

that, IoT technology passes the resultant specifics to

a distant server. Figure 8 displays the hardware design

result of the suggested solution, in which the web

application output pages are clearly shown on further

figures.

5 CONCLUSION AND FUTURE

SCOPE

The creative health monitoring system that has been

proposed enables physicians to easily identify the

information of each patient on the display monitor

located at their location. Doctors can differentiate

between the data of a specific patient with respect to

their previous values and their current values. In

addition to data recording on the cloud, the Internet

of Things offers the potential to incorporate

additional biomedical sensors and more advanced

features or advantages into this system.

Consequently, the capabilities of IoT technology

render this monitoring system more adaptable and

upgradable in the future. A low-cost, user-friendly

monitoring system for signature signs of highly

sensitive patients is proposed. Vital signs are

accurately sensed, converted into clinical indicators,

and displayed on a central screen and web server, in

a manner that communicates wirelessly with Wi-Fi-

enabled networks or specially-constructed wireless

IoT devices. In summary, blockchain technology has

the capacity to transform healthcare delivery and

outcomes by improving patients' empowerment,

interoperability, transparency, and data security.

Although challenges and constraints persist, ongoing

research and collaboration will foster innovation and

establish a future in which blockchain-enabled

healthcare systems enhance the quality, accessibility,

and equity of care for all. Additionally, this work can

be improved by incorporating certain deep learning

concepts to instantaneously determine the healthcare

status and provide users with the corresponding

information.
