The document describes a software architecture block diagram for a smart driver application. The block diagram shows several modules including sign in/sign up, trips, business logic, push notifications, GPS, settings, and help. Each module is then described in more detail with information on interactions and data flow between components. Key modules include sign in/sign up for authentication, trips to view user trips, GPS for location data, settings to update user preferences, and push notifications triggered by business logic.

Each module in this block diagram is detailed below with the interactions between components within
each module separately.
Sign in/Sign up Module:
The application user using the smart phone has two options.
1.) Sign In : The user logs into the SmartDriver application with his credentials which gets validated in
the background with the Mobile Database. If the user entered the proper credentials the user gets the
access to use the application otherwise he is restricted from accessing the application.
He is also shown a hyperlink which asks him to sign up to the application if he is a first time user.
2.) Sign Up: The user is treated as a new user and therefore he needs to provide genuine details such as
personal information, official information and answer security questions. These are the checks which
prevent miscreants or software attacks that stall the application’s performance.

Push Notifications Module:
Business Logic determines when to trigger notifications. It is based on hard breaking and rapid
accelerations. Whenever the required conditions are met, push notifications are triggered and delivered to
the device by APNS server(in Apple) or corresponding push notifications services in other devices.
