SafeCode

SafeCode is a software/hardware solution to handle digital safe-calls for independent in-call sex work.

Project Status

• 2013-06-02: Started writing software. Frontend now loads and connects to the web service, as does the backend daemon. Still have some cleanup/reliability improvements to do, but basic functionality is there (minus hardware interfacing).
• 2013-06-01: Started thinking about/planning.

Hardware

• Small/portable box
• Rugged design, as it will be thrown in bags/traveled with constantly
• USB connected/powered
• Keypad on top to enter data (Storm 6000-21001, telephone-style 12 key + Cancel, Clear, Help, Enter)
• Lighting to provide feedback for "entry received" and such
• Beeper for indicating exceeding check-in time without checking in

Software

• Daemon that runs on the local machine talking to the SafeCode box
• Web service that runs on an outside server that reports status to others
• Keepalives between all components to indicate that a connection was broken

Web Service Architecture

• Sinatra-based daemon
• Accepts WebSocket connections from the daemon talking to the SafeCode box and monitors to ensure that connection stays open and that keepalives are being received
• Serves web pages & uses WebSockets to update status in real-time for anyone monitoring
• Keeps state of:
  • Current geographical location
  • Connectivity to daemon
  • Daemon's connectivity to the SafeCode box
  • Session state
    • Not in session
    • Client arrived, no check-in yet
    • Check-in OK, in session
    • Check-in non-OK, in session
  • Time of next expected check-in (if in session)
