Sensory Recovery and Duress Detection

Recovery and ongoing authentication can be based on personalized sensory cues and biofeedback.

Traditional recovery relies on passwords and emails. Sensory recovery uses recognition—melodies, image sequences, haptic rhythms—as the key. These cues are personal and difficult to steal.

Recovery Through Recognition

You set a unique sensory sequence. When you need to recover access, you are presented with variations and must identify the correct one. The system never needs to know the meaning; it only checks recognition.

Continuous Authentication

Your device monitors your usual patterns and checks for anomalies. If your behavior shifts unexpectedly, it triggers a sensory challenge. This can prevent unauthorized access without constant friction.

Duress Detection

Biofeedback can detect stress signals—irregular heart rate, trembling voice, unusual movement. The system can respond by locking sensitive actions or alerting trusted contacts.

Design Considerations

Sensory recovery and duress detection turn personal perception into a secure fallback, blending protection with user experience.
