## 4 Results Analysis
### Data Collection and Analysis  
For the evaluation of the proposed health monitoring framework, real-time data collection played a vital role. During real-time data collection, the anonymous subjects were monitored at four different places both public and private including a work center,  
Figure 7: Working methodology of the proposed system. a shopping complex, a bus terminal and a medical center, as shown in Figure 1. The monitoring was performed at the entry points of all the data collection venues. The test dataset included the body temperature of 5278 subjects of all ages along with facial images and GPS locations of the respective subjects. During the process of data collection, both the proposed FCMN-based monitoring system and standard market available devices were utilized and a selection of the data at different locations is presented in Table 1. The measurement errors due to human negligence were removed during pre-processing of the data. Further, it was observed from the comparative analysis of received data as presented in Table 1 that the proposed health-monitoring framework worked with a minimal amount of error, as presented in Table 2. The graphical analysis of the proposed monitoring device is presented in Figure 8. \begin{table}

Table 2: Analysis of proposed system. In the FCMN-based proposed monitoring system, the subject-specific data is stored on a cloud server as serial number, body temperature, facial image, date and time along with the GPS location of the subject. The privacy of the health data was taken into consideration and the received data was encrypted while stored on the cloud server.
