WiFinder

WiFinder

Our solution uses WiFi to to a quick handshake between the controller and the passenger apps. 

When the controller enters a vehicle their phone is providing a WiFi hotspot, which passengers' phone will automatically connect to. Upon connection, the passenger app sends a message containing current valid tickets as well as personal information. After receiving an acknowledge by the controller app, the passenger's phone disconnects from the WiFi.

Main advantages

• A controller can now immediately see if there are passengers with expired or no valid tickets
• Passengers only need WiFi on their phone enabled
• No physical interaction is needed
• No jamming of other communication channels (bluetooth)

Security Measures

• All data is transferred encrypted
• The quick disconnect after receiving an acknowledge combats WiFi spoofing
• Every registered passenger will have a phone saved into their settings, which can not be changed quickly. This avoids sharing of the app/tickets

Deliverables

We plan to deliver a proof of concept app pair that sends the message with the data (mocked data) and acknowledges the message. In detail:

• Passenger app with data saved that sends the data upon WiFi connection
• Controller app that receives and acknowledges the app, as well, as shows the ticket status of the passenger
