If you want a tool to help you figure out who you're talking to on a video chat without relying on a third-party service, LiarLiar is a good option. The AI-powered system can spot lies and changes in heart rate during video chats by analyzing small movements, heart rate, body language and tone of voice. It works with common videoconferencing tools like Zoom, Google Meet and Skype, so it's not hard to set up and use. The system can help you establish trust and communicate better by spotting subtle signs of deception in real time.
Another good option is ShakeMyHand, an authentication app that generates one-time passwords to help you verify identities. It uses passphrase combinations and QR code scanning to perform the verification, and because the codes are generated on both ends, you and the other party must be physically present to generate them. The app offers a way to verify identities in digital interactions like financial transactions and team membership without a central server.
