Abstract— his care. Medical records form an important part

Abstract— The project
entails facilitating better healthcare services using NFC enabled devices. The
NFC enabled devices offer an easy and secure way for self-reporting of health
status information. The project involves use NFC tag. NFC is used to collect
important information about the patient such as the blood sugar count, pulse
rate, ECG etc. Thus the doctor can access the patient’s data through just a tap.
medical data is confidential information that must not openly be available to
anyone with physical access to the storage media. We make a technology to
provide secure and quick access to medical information.

It is very
important for the treating doctor to properly document the patient under his
care. Medical records form an important part of the of a patient. It is
important for the doctors and medical establishments to properly maintain the
records of patient. It will help them in the scientific evaluation of their
patient profile, helping in analyzing the treatment results, and to plan
treatment protocols. Medical records include a variety of documentation of
patient’s history, clinical findings, diagnostic test results, preoperative
care, operation notes, post-operative care.

INTRODUCTION

Our
aim is to create a system that can use NFC to give a person a unique id that
can never be erased and will prove to identify a person, we want to create a
system which will help India & its government to digitize India. Also to
create a system that can use NFC to reducing the paper work required during the
registration of the patient and also eliminates the disadvantages of using RFID
based system.

It
is very important to maintain efficient software to handle information of a
patient. This application provides away to record this information and to
access these in a simple way.

 

·        
BASIC CONCEPT

The
planned Near Field Communication (NFC)tag is supposed to hold emergency data.
Near Field Communication (NFC) technology to provide secure and quick access to
medical information. The tags can be placed inside the body. Thus the doctor
can access the patient’s data through just a tap. medical data is confidential
information that must not openly be available to anyone with physical access to
the storage media. We make a technology to provide secure and quick access to
medical information.

RELATED WORK

 

Medical
Records are replacing Paper Medical Records which is now considered a key
initiative in the Healthcare industry. It is because hard copies of medical
records are easily lost and damaged and also disappears in case of emergencies.
They are often incomplete with incorrect or missing information. Doctors
therefore end up duplicating tests, making uninformed decisions and delaying care.
Attempts have been made, using in both RFID and NFC technologies to convert
them into digital formats.

The
NFC based system is used to store copies of the reports generated by the doctor
and display them the next time the visit a doctor. Whereas, the RFID based
system provided a wider scope to store and retrieve the medical records of the
patients but it was a desktop bound software and required scanner to process
the RFID tags, which led to low portability and data access became obsolete for
an on-site attendant in case of an accident.

NFC
is a comparatively novel wireless communication technology that is primarily
used for mobile payment and ticketing applications involving smart cards or
mobile devices. It is a short range high frequency wireless communication
technology that allows data exchange between devices that are about four inches
apart.  Due to the majority of NFC
applications using sensitive data, e.g., personal details, a comparatively
large body of scientific literature deals with security aspects in NFC
applications

EXISTING SYSTEM

Whenever
there is an emergency in the hospital the doctor has to search all the details
of the particular patient which is so much time consuming. For example, a
person is suffering from a particular disease and goes to the hospital for the
checkups. So the normal procedure will be the doctor will ask for so many
checkups which is again so much time consuming. There is no intelligence of the
software in such cases. In the existing system all the patient details and
regarding the tests done to the patients prescribed by the doctor is maintained
manually by the receptionist. Also there is no proper search technique to check
the patient information.

WHAT
IS TO BE DEVELOPED

Whenever
there is an emergency in the hospital the doctor has to search all the details
of the particular patient which is so much time consuming.

For
example, a person is suffering from a particular disease and goes to the
hospital for the checkups. So the normal procedure will be the doctor will ask
for so many checkups which is again so much time consuming. So by using the NFC
(near field communication) it will be easy for the doctor to maintain the
record of the patient. In this project there will be a chip which consists of a
unique id called as NFC tag. And that chip will be fixed in the patient’s hand.
By using the NFC reader, the doctor will be able to find the previous record of
the patient which is stored in the cloud. Again if there is any new patient
then the doctor will insert the data in that chip only and that data will be
store in the cloud. So it will make easy for doctor to search any patient’s
record.

Patient
will be equipped with NFC tag. The medical application (In-built NFC
reader/writer) writes the link of the patient into the NFC tag from smart
phone. To create patient application, we are using ANDROID studio. Although
substantial progress was made in improving the sharing of patient medical
information among healthcare providers, professionals still need to address the
issue of efficient electronic medical records. In emergency situations,
particularly with unconscious, incoherent and unaccompanied patients, providing
emergency physicians with a patient’s accurate medical history could be the
difference between life and death

TECHNOLOGY
USED

Near field communication,
abbreviated NFC is a type of contactless communication between devices like smart
phones or tablets. This type of communication allows a user to wave the smart
phone over a NFC compatible device or tap it on a NFC tag to
send/receive information without needing to touch the devices together or go
through multiple steps setting up a connection.

 

How
It Works –

 

The
technology behind NFC allows a device, known as a reader, interrogator, or
active device, to create a radio frequency current that communicates with
another NFC compatible device or a small NFC tag holding the information reader
wants.

Passive
devices, such as the NFC tag in smart articles, store information and
communicate with the reader but do not actively read other devices.

Peer-to-peer
communication through two active devices is also a possibility with NFC.

This
allows both devices to send and receive information.

 

·        
PATIENT
IDENTIFICATION USING NFC TAGS

When
Smart phone are placed near the NFC tag, data will be accessed and this unique
ID will be sent to server to select the appropriate record. This tag can be
assigned to patient with a unique ID at the time of registration. NFC based
Identification developed for Android platform will run in all NFC enabled
Android smart phones. For successful identification it opens up the patient
records and display information coming from the backend server system. If not,
then the record application displays the message of unidentified ID.

·        
NFC
Tag Reader/Writer

The
writer/ reader will be in-built so that users do not have to download separate
NFC reader/writer, for adding tags and reading

others
tag. This also makes it unique and secure form other general tag readers. NFC tag readers are not commonly available in market,
as NFC technology is new and developing, its devices and readers are also a
very few, some of the latest mobiles have NFC reader implanted

in them, hence the app can use this
mobile to read and write these tags

METHODOLOGY

 

1.       
Result and Analysis

 

Data flow from wireless sensors to NFC enabled devices.

Data from the sensor nodes can be transmitted to the
base station node through piece of coding. Through the initialization of the
sensor component and using the statement data can be sent to the base station
frequently. Since sensor nodes broadcast the data, we need to have certain
validation to make sure that data received is from the right sensor node. 

 

2.       
Communication over NFC

              

The NFC Data Exchange Format (NDEF) is a standardized
format for storing formatted data on NFC tags and for transporting data across
a peer-to-peer NFC link. The data from the buffer can be incorporated into a
NDEF format and can be written to NFC tags. An NDEF record consists of multiple
header fields and a payload field. The header contains five flags – Message
Begin (MB), Message End (ME), Chunk Flag (CF), Short Record (SR)and ID Length
Present (IL), as well as a type classification (Type Name Format, TNF), and
length information for fields of variable length, a type identification (Type)
and an optional record identifier (ID).

 

 

3.       
Authentication of NFC receiver devices

 

I) At first the receiver will send a data transfer
request along with its International Mobile Equipment Identity (IMEI) and
public key.

 

II) The sender then authenticates the receiver with the
received ID which should be stored prior to start of data transmission.

 

III) If the receiver ID is stored in sender mobile then
the data communication will begin which provides security and authentication of
receiver.

 

·        
CONCLUSION

The system is aimed to collect the medical data of
patients

automatically, from the wireless sensors to base
station, then to the center database. This system is intending to provide a
hassle free and smooth medical data access in case of emergency and for daily
routine basis. It bridges the gap between patients and doctors in terms of
communication and provides a unique and secure platform to interact, thus
providing to better healthcare services. A paperless system which will make the
Identification of a person easier and authentic. Use of NFC tags increase
authenticity of data as they cannot be overwritten.

 

·        
FUTURE
SCOPE

In future NFC devices can be made independent of any
other equipment, like mobile phone in our case. It can be in the form of a
small chip consists of passive NFC tags attached to patient body and there can
be active NFC receiver attached in the patient’s environment. This active NFC
receiver can also be placed in several places in hospital. In this way, it is
also possible to find the patient location.

 

·        
LIMITATIONS

 

        
i.           
Limited use of NFC enabled devices. Not
too many phones available in market support NFC.

       
ii.           
Need to install an application in
patient’s phone that collects the data from base station taken through the
serial port.

      iii.           
Not able to identify the patient
location and cannot get the data from remote location.
