Abstract

During law enforcement or rescue searches, one is limited by certain constraints. During a warrant based search there are limits imposed by the warrant - perhaps for the size of the object to be found. If the warrant is for a person suspected to be hiding in a house, searching closets is permissible, but searching the drawers of the bedside table is not. When searching for smaller objects, one is limited by time and the creativity of the searcher, pitted against the creativity of the searched. When searching an outbuilding suspected of harboring a drug or weapons lab, searching for cans of specific chemicals hidden within a nest of innocuous chemicals may not be fruitful. More importantly, the searcher may not be schooled and may miss evidence. When searching for a lost or missing person, often line abreast searches are used. However in thick or difficult terrain a searcher may pass within a few feet of critical evidence and not see it.

RFID and profiles in searches

Increasingly, items are sold with imbedded RFID tags. These tags while only transmitting a few feet can be quite useful in the above described situations.

During a search an RFID scanner can alert a searcher to a tag that he may not see while traversing a search zone. The scanner can be programmed to rate RFID tags it encounters. Suppose the lost person were wearing clothes purchased at Walmart - they could still have the RFID tag with the Walmart ID.

In a lab search, the scanner could be programmed to look for and alert on combinations of ingredients that are signature of explosive creation or methamphetamines.
