Claims:We claim:
1. The public places include many facilities for human care and welfare and so the health emergency should be noticed at very instance especially in case of air-borne communicable disease.
a. The vital signs of infection like sneezing, cough, temperature rise, blood pressure variation and other signs can be noted at Medical aid system installed in public places with communicable devices and network
b. The short term and long term infection can be monitored in such system with appropriate sensors to identify the unnoticed infected person
2. The communicative disease can be best monitored at common organization through the implementation of such system of monitoring and deployment of medical assistance at initial stage
a. The authorized medical team connected with the system imparts the physical parameter limitations to decide the emergency.
b. The database also includes the list of public health centers with facilities available in every center to determine the best service possible at short notice of emergency.
c. The further medical observation and analytic procedure of affected person can be done through such facilitated health center to define the authenticated service.
3. The data communicated to the cloud in very secured manner to avoid hacking trials.
a. The physical and contact details transmitted are encrypted to serve the purpose of secure transmission.
b. The data at communication layer can be encrypted with AES 128-bit encryption and application layer with WPA2 to impart security
c. The above algorithm are not limited and can be included any advantageous algorithm to improve data security.
4. The shared data about the incidence includes the details of victim and aid suggested to reduce the anxiety at the guardian end.
a. The responsive notification with the victim details with medical support suggestion sent tom the guardian as provided by the victim
b. The above is not limited to personal intimation and the same can be notified through other means of communication which can further developed in upcoming works.
5. The public organisations like school, college have the record of communication details like address, phone number and mail address to communicate
a. The other organizations does not hold such record may find other sources of personal data for further communication in this regard
b. The authorized data can be shared securely through the use of biometric authentication of the person in case of emergency.

, Description:Description of the system
The system proposed here is of great importance as the medical emergency not cared at first instance leads to risk of life. Every populated institution like schools, colleges, malls and other public places are to be equipped with such sensor/actuators connected with wireless routers and adapters to transmit the recorded data with basic personnel data like name, address, contact number and any infection detected earlier along with caretaker details are to be sent to the public hospital in the close proximity. The devices installed in specific zone for the specific purpose used here with wireless network and cloud enabled data storage and data sharing mechanism. The sensor enabled devices record the body parameters along with personal data and contact details.The microcontroller board can be programmed using Arduino or Raspberry Pi to detect various parameters like body temperature, heartbeat, pulse, blood pressure and an electronic echo cardiogram. The various sensor embedded in specific zone of public places like school, college, shopping malls and entertainment parks can be featured with communicable disease detector to identify any infectious air-borne diseases. This kind of medical diagnosis may be used for further investigation and clinical treatment and instantly avoid unnoticed physical illness. The old age and kids who are prone to communicable disease with less immunity can be diagnosed at initial stages of infection. The life-killing viruses mostly are communicable through saliva and other body liquids can identified at early stages in such public places can save the infected and other persons. The sensor here used is compatible with Arduino and raspberry pi to enable effective programming. The sensors collect human physical data which are then processed in the microcontroller are transmitted through wired/ wireless network containing devices, routers and switches to be stored cloud data storage unit.The purpose of cloud data storage is to cause history of events and to notify any critical value recorded to be sent to the nearest public health center to initiate any emergency response medical assistance. The abnormality noticed can also be transmitted to the victim guardian at the earliest through cloud environment. The communication layer and application layer of the cloud platform are encrypted to bring ethical privacy of human data. The communication link layer secured with AES 128-bit protocol and WPA2 protocol for prime communication types. The application layer imparts HTTP secure protocol across the sensor and the web server of the cloud environment to bring secure tunnel based communication. As these modules are proposed to be placed in public places, the medical data are prone to hacking attacks which are best avoided through such protocols. The wireless device transmits the data with reduced latency and minimum bandwidth when used recent wireless communication technology like 4G. The cloud environment records transmitted health data and compute for any anomalies in the body parameters which are as advised through the authorized medical team. The cloud environment when find an noticeable record transmits the same to the nearby public health center. The message also be sent to the victim guardian which is given by victim during monitoring stage of system installed public place. The message can be along with medical suggestion of medical team visiting the victim. So the guardian can aware the medical aid to be given at an initial stage before actually visiting the place. The kind of medical diagnostic is more helpful in case of school children and adults who visit public places without parental accompany. The medical data recorded encrypted at two levels of communication adds more security against hacking issue. The securely transmitted medical data processed in cloud environment for the anomaly guided by authorized medical team to notify such occurrence among the close proximity public health centers. The data about health centers and available personnel and equipment assistance are stored in cloud for emergency aid mapping. The cloud computing devices analyze various health center for real-time available devices and personnel for medical care. The victim guardian has to be notified of identified anomaly with the medical team visiting detail to insist the necessary action initiated from the institution
