## 4 IoT Contribution to Monitoring Systems
### Security Aspects of Data for IoT-Based Big Data Transmission & Management over the Cloud
In addition to this, our proposal counts on the improvement of major features of the IoT because, in the healthcare sector, these specific features are of major importance and must be taken into account to achieve a properly structured system. Finally, we proposed an algorithm approach to transmitting and processing video/image data through a Cloud-based Monitoring system. Through our findings, we concluded that our proposal operates more efficiently due to the Digital Twin scenario that uses, and additionally, the proposed algorithm provides

Figure 9: Energy Consumption Comparison (Consumption in/Time in minutes) (scenario D) [61; 62; 63; 64; 10]. a more secure production and transmission of the data used in an IoT-based Healthcare Monitoring system. By the figures of the experimental results section, we can observe that the algorithm proposed in our work offers a more secure transmission of the data through time, and offers larger amounts of data used and transmitted in the communication channel. With this, we can have a more reliable and secure IoT-based Healthcare Monitoring system in the Cloud, which uses all the advantages of the involved technologies to the maximum. Furthermore, we can observe that the operation of the proposed scenario as a Digital Twin scenario offers a more sustainable and energy-efficient system. To attain the best outcomes in its utilization, we advise combining the Internet of Things with video monitoring technologies in future investigations. Additionally, as a result of this research, we would further examine the types of monitoring that could benefit from the Internet of Things contribution to technology. Since MCC serves as the foundation for both IoT and monitoring, we can assert that the former enhances IoT functionality and has an impact on different types of monitoring technologies. Finally, as we can deduct from Figures 2 and 4 that a huge and vital issue for future study is the data security of video monitoring through Cloud and IoT environments. Thus, there is a strong need of further research in this area and, due to this, we are planning to overcome all the difficulties to establish a system like the one proposed for buildings, such as small hospitals or small schools, in order to examine the operation of our proposed scenario.
