I need answer with details of requirement no 3.4.5.6

Scenario (problem identification): A restaurant owner is concerned about the low satisfaction level of his customers. The customers' feedback shows that the process of tables reservation was difficult, especially with the small number of staff in the restaurant. The customers were also worried about the flow management inside the restaurant, mainly because of the Covid-19 pandemic. Moreover, there were many complaints that orders take a long time to be serviced to the customers due to the lack of coordination between the kitchen and the waiters. Consequently, you are being hired by the restaurant owner who would like to make use of technology to improve the quality of service at the restaurant. The owner also wants to automatically manage the reservations and customers' flow (entering/exiting), according to the number of available tables. Additionally, he hopes that you could help with improving the coordination process between the kitchen and waiters. Finally, he would like to automate the attendance management process and control the access to the managers' room by only allowing those who have permission to access the room. Requirements: - Propose a solution for customers' flow and tables reservation by deploying loT devices. - Explain how loT can be used to improve the coordination between the kitchen and waiters. - Provide a solution using loT to automate the process of attendance management. - Use loT to control access to the management room by checking the given authorisation of the person before entering the room. - All required equipment (e.g., boards, sensors, cameras, etc.) must be listed with your solutions along with explaining how that equipment is being used. - Demonstrate security issues (cyber/physical attacks) that might face your proposed loT system in the restaurant. Recommendations must also be provided on how to avoid these issues. Assessment criteria: - (4 Marks) Clear and specified explanation of the proposed solutions. - (2 Marks) Effective identification and recommended countermeasures for the potential security issues facing the used loT devices in the restaurant. - (2 Mark) The use of figures to explain the proposed solution. - (1 Marks) Listing of the required equipment (e.g., boards, sensors, cameras, etc.) - (1 Marks) The use of external resources to justify/clarify the proposed solutions
