Scams have evolved with AI, and it’s heartbreaking how often older adults are the ones most impacted. Many get targeted by convincing deepfake voice calls from someone pretending to be a loved one. We wanted to create something simple, accessible, and proactive that could help stop these scams before they cause harm.
Trustline is a scam call protection app built for older adults. It listens for signs of deepfake voice scams in real time and sends an SMS alert during the call, giving the user a clear warning so they can take action immediately.
We focused on making the experience as straightforward as possible:
- A simple signup with name and phone number
- An easy on/off toggle for protection
- Clear on-screen indicators
Behind the scenes, our detection engine monitors call audio for suspicious patterns and triggers alerts instantly.
- Balancing speed and accuracy in scam detection
- Designing a UI that’s genuinely comfortable for older adults
- Building trust while handling sensitive information
- Created a working prototype that can detect and warn about suspicious calls
- Designed an interface tested for clarity and ease of use
- Empathy-driven design is key for adoption
- Real-time protection needs to be invisible until it’s needed
- Add more accessibility features
- Start beta testing with older adults
- Expand support tools like a built-in help chatbot
