Recently you have been hired as a programmer in a software company. There are three members in your team. Your team is assigned to build a secure Telehealth system for patients to submit questions to their doctors and get response messages. The system should have the following requirements.

• User registration (after successful registration with username and password, the program will show a successful message, otherwise it will show a warning message for one failure attempt)
• User login (a user can be a doctor, patient, or administrative staff, who can log in from anywhere)
• Add questions (by patients)
• Delete questions or add comments (by administrative staff)
• View and answer questions (by doctors)

In addition to the above-mentioned requirements, you should consider and take care of the security measures such as input validations (e.g., username should not be more than 30 characters), buffer overflows, etc. that are relevant to the Telehealth system.

Now do the following tasks based on the information above.

1) SECURE DESIGN. List the use cases and misuse cases of the system. Draw a flowchart to illustrate the software design. Reasonable assumptions can be made.
