Abstract
A tamper detecting enclosure arrangement for enclosures (10) containing an interior space (11) in which a protected item (14) is positioned having a magnetoresistive sensing memory storage cell (16) positioned in or near the protected item (14) in the enclosure (10) having a two state offset magnetoresistance versus externally applied magnetic field. A magnet (13) is positioned at a selected separation distance from the magnetoresistive sensing memory storage cell (16) to thereby provide a magnetic field about the magnetoresistive sensing memory storage cell (16) if said enclosure (10) has not been opened in such a manner as to result in substantially increasing said separation distance.
