An anti-abduction system and method is disclosed which utilizes a radio
frequency transceiver attached to a slave to communicate with a
corresponding master transceiver to detect and prevent abductions, which
may be advantageously applied to situations in which child abduction is a
possibility. The disclosed system and method utilizes communication
protocols to notify the master of the proximal locality of the slave unit
and any spatial deviation of the slave from the master. Utilization of
varying strength transceiver signaling between the master and slave
permits the distance between the master and slave to be approximated.
Additionally, the slave may contain an optional heartbeat monitor to
detect and report situations in which the device is removed from the
potential abduction victim. The present invention may be generally
targeted towards preventing child abductions, but has applications as an
anti-terrorist device in preventing kidnappings of political persons and
other innocents by terrorist groups and the like.
