Healthcare is a sector which has been gaining immense scrutiny nowadays. Various ongoing advancements made in computing and network technologies have been stemming the domain of medicine to grow from hospital centered towards wellbeing centered. This paper emphasis on delivering healthcare services in a more efficient, smarter, quality focused and patient centered manner. To accomplish this, we are adopting technologies like cloud computing and internet of things. Amalgamation of cloud computing and IoT is referred as CoT which aims to unfold Things as services via applications. Most of the proposed cloud based iot heath care monitoring framework includes three components i. e. data acquisition which uses sensors and actuators, sending the captured data in real time which is due to the data transmission, the data captured is sent to the data center of heath care organization in a more secured way and the cloud processing is for visualization, analytics and storage. Our proposed system is a suite of software which keeps track of patient’s health records delivering a low cost and quality focused and time efficient treatment by speeding up the process of diagnosis.

In [2] Renyou MEI and Xiaoli QIU emphasized on introducing the concept of cloud computing into the medical information system, by designing a concept which implements the general medical information management system in order to improve the efficiency and medical service. Their proposed system drew lessons on distributed storage and efficient processing of general medical data by provides data management services for users.

In Abdel Fattah Awad, Mohammed Bakri Bashir, Tawheed Hassan Ahmed and Adil Yousif proposed a system encompassing various forms of image retrieval techniques in distributed systems. The authors are concentrating on the platform, modality, dataset, image file type, the retrieval technique used and various other factors like duplication in order to provide optimized image retrieval technique in distributed system.

Developing an application is a big investment, and the fundamental stages of the project should be providing a solid 'building material'. Design is one of the cornerstones of an application’s future, it is a point where the idea begins it manifestation in the real world. Health Applications allow all the healthcare providers to connect with each and every patient, dynamically and quickly, reaching out to them according to their convenience.

The application is made easy for end users to use as they can store and access their information and can be used for various systems like phones, tablets etc. The app will engage with the patients, offering them ubiquitous access to the products and services which serve as a part of user experience. The user can store their past health records and the staff of the hospital can directly upload the patient’s current reports and data according to the profiles. Basically all the health records would be maintained which can be accessed anywhere and anytime by the patients, doctors or the staff because of which the patient can be diagnosed more quickly and even the recommendations can be provided. The Data will be secured as it would be encrypted so there would be no security issues.

Working Model of the Application

Healthcare professional’s information would be available along with the information of the nearby hospitals by using the google maps API the information of the hospital will be available on the map along with the nearest route location so that the patient can reach on time. The application would also have an emergency button. With one touch click on “EMERGENCY" icon on Home screen, Emergency SMS of your approximate location can be sent to the nearby ambulance services and even the notifications would be sent to nearby hospitals.The prescriptions provided by the doctor would be uploaded on the profile of the patient which will have the read access to the pharmacists so that the wrong medicines would never be provided by them and even the patient can read which medicines they have to buy. The patients can also consult the doctor either by video consultancy or either by chats in case the patient is not able to move the importance of cooperation between patients and healthcare professionals and strive to facilitate it by providing a better consultancy option. IV. Technology UsedA.

Internet of Things (IoT)

Internet of Things refers to scenarios where network integration and computing capability which extends to objects, sensors and actuators not normally considered computers, allowing these devices to produce, exchange and use up data with minimum human intervention. there is no single universal definition of IoT. The abstract idea of combination of computers, sensors, and networks to monitor and control devices has existed for decapods. The recent concursion of several technology market trends is bringing the IoT closer to reality. There is inclusion of Ubiquitary Integration, Boundless Embracement of Internet Protocol-based Networking, Computing Economics, Notarization, Advances in Data Logic, and the Rise of Cloud Computing. The Internet of Things (IoT) is area which has the access to the advantages of Wireless Sensor and Actuator Networks (WSAN) and Prevalent Computing domains.

There are different applications of Internet of Things which have been developed. Researchers has well identified the opportunities, challenges and technology standards used in IoT such as Radio-Frequency Identification (RFID) tags, sensors, actuators, mobile phones, etc. This paper covers the different applications that conflux smart technologies so far and presents the overview of the sensors and its standards. Basically, The Internet of Things describes connection of network of devices— to the internet using embedded software, electronics, actuators and sensors to communicate, collect and exchange data with one another. With Internet of things, the world is broad open, offering a virtually ample amount of opportunities and connections at in every field.

Cloud Computing

To be considered fully virtualized, computers must be allowed to be built from distributed components such as processing, storage, data, and software resources which is computed by itself. Cluster, grid, and now, cloud computing all these technologies aims at allowing access to large amounts of computing power in a fully virtualized manner, by collecting resources and offering a single system view. Utility computing describes a model of business for delivery of computing power on-demand; consumers pay providers based on usage (“pay-as-you-go”), similar to the way in which we are currently obtaining services from traditional public benefit services such as water, electricity, gas, and telephony. Cloud computing is a term which describes a category of sophisticated on-demand computing services initially offered by commercial providers, such as Amazon, Microsoft, Google. A model is denoted in which a computing infrastructure is viewed as a “cloud” from which individuals and organizations access applications from anywhere in the world on demand. Main principle of Cloud Computing is offering computing, storage, and software which acts “as a service.

Smart Health Care

Medical is a field which is undergoing in a broad range of transformation which is the result of growing advances in computing and networking technologies. Healthcare is changing from suspective and hospital-centered to preventive and personalized, from disease-focused to patient-centered. The healthcare systems, as well as fundamental medicine research, are becoming smarter and improves the quality of life for everyone. We count on for significant advancements to support behavior changes through technology-enabled self-management, and social and motivational support. Moreover, with smart technologies, delivery of healthcare can be made more efficient and of higher quality and also cost efficient.

Near Field Communication (NFC)

NFC stands for “Near Field Communication” and, as the name implies, it enables short range communication between congenial devices. There is requirement of at least one transmitting device, and one other device to receive the signal. There are range of devices which can use the NFC standard which will be considered either passive or active. As shown in Figure [5] the Passive NFC devices inculcates tags, small transmitters, which can send data to other NFC devices which eliminates the need for a power source of their own. NFC don’t really process any information sent from other sources, and doesn’t establishes a connectivity to other passive components.

Illustration of an NFC Card

Active devices can send and receive data and can connect with each other as well as with passive devices. Smartphones are the most common form of active NFC device. Touch payment terminals and Public transport card readers are good examples of these technology. Bluetooth and Wi-Fi seem somewhat similar to NFC. All the three allow wireless communication and exchanges data between digital devices like smartphones. Yet NFC make use of electromagnetic radio fields while Bluetooth and Wi-Fi focus on radio transmissions instead. Near field communication, or NFC for short, is a faction of radio-frequency identification (RFID) with the debarment that NFC is designed for use by devices within close immediacy to each other. There are three forms of NFC technologywhich exists i. e. Type A, Type B, and FeliCa. All the three are similar but they communicate in slightly different ways. FeliCa type of nfc is commonly found in Japan.

Devices which are using NFC may be active or passive. An NFC tag, contains data that other devices can read but does not read any information itself. Other devices can read the data, but NFC itself does nothing except transmit the information to devices which can read the data i. e. the authorized devices. Active devices can read data and send it. An active NFC device, like a smartphone, would not only be able to collect information from NFC tags, but it would also be able to deal information with other congenial devices and could even amend the information on the NFC tag if authorized to make such changes. To guarantee security, NFC often set up a riskless channel and uses encryption when dispatching sensitive information such as credit card numbers. Users can further secure their private information by keeping anti-virus software on their smartphones and adding a key to the phone so a hacker cannot use it in the event that the smartphone is lost.

Conclusion and Future Scope

Patient’s health needs to be examined from time to time and the information must be transmitted to doctors, nurses, pharmacists etc. via internet for analysis of health and also for the recommendations. In this paper, we have used the encryption algorithm to tackle the problem of privacy preservation risk, and also efficiently providing the data of patient. The application focuses on smart healthcare and there is encapsulation of many medical services. While collecting information the data will be encrypted and decrypted using keys and only the authorized users will have the access of data. The data will be stored in the cloud using cloud computing. Cloud computing will be used to store a large amount of medical data which allows easy access and management of the data on remote servers rather than local server or personal computer on which the data can be lost due to some reasons. Cloud computing provides a more secure environment and the data also can be accessed anywhere and anytime. In this article there is also use of IoT i. e. the use of near field communication (NFC), which will be provided to the patients. The NFC will store a Unique Id of the patient which is read by other device within seconds and all the data of the patient will be available easily. This will be helpful in case of emergency (accidents) as the information of the patient will be available within seconds just by reading the NFC tag. In this way the data sharing scheme is secure and also time efficient and the focus will be renewed to patient-centered care.
