The inspiration was: interruption-based security architecture.
The concept: Someone is detained. He was suppose to ping the system saying "I'm OK", but he can't. Because of this, a series of smart alarms are created.
System: online alert system optimized for mobile usage. The system is intelligently linked to the Circles of Support. Organizations are politically and geographically related in both sense, local and global. A SMS could be geo-tracked if the mobile operator decided to. A legal representative tries to call detainee's cellphone in case that anyone responds (either the detainee or the detainer) and provide support if necessary.
Alerts (v1.0): A first alert is sent to the family of the subscriber. They must confirm to the system that everything is fine. If they don't do so then the system send to them a package containing clear guidance and useful information for them to start acting proactively. If by a certain period of time the alert hasn't been turn-off (which means the family hasn't reported the subscriber is now OK), subsequent alerts will be sent to outer circles of support. An alarm cannot be set for less than 1 day.
Subscriber: someone who consider themselves under risk, register using either mobile or desktop device. They fill up a form explaining why they consider themselves under risk. A profile is created (with personal and context information). User sends SMS to the system every period of time (could be established depending of level of risk).
