Accessing It
• Input device
• User Interface – Login, Initial Settings,
Operations, Logout
Interaction with HACS
The user can interact through any input device such as the
Laptop, Palmtop, Cell phone etc..
• The user interface allows the user to enter or tell the user
name and password.
• The user can also provide fingerprint or retinal scan for
authentication.
• The system then transfers the details to the authentication
server and the authentication server allows or denies the
user according to the information provided.
• After Authentication, the user is allowed access into the
system
System Design
• HACS is a system which is controlled by a remote system
such as a cell phone, and controls home appliances such as
VCR
• In case of emergency such as fire, the user or an
organization such as Fire Department should be notified.
• Also, HACS should have a database of information about
the users and appliances.
