Security Data Features

• Ensured only verified users on the system can send out alert reports and make phone calls.
• Ensured verified users can only send reports about their polling units within a 200m radius.
• Increased network connectivity by saving crucial data such as JSON files and user information the system uses on the user’s phone.
• Ensured that only authorized users can create, read, update, and delete information on the database.
