System and method for object entry and egress control in a predefined area
First Claim
1. A method of loss prevention of an object from a predetermined area comprising:
- reading a key ID tag at an entrance of the predetermined area bearing a source ID and an algorithm code, wherein the algorithm code identifies an algorithm for calculating a target ID from an algorithm database;
calculating, by a central control system, a first calculated target ID based on the source ID in accordance with the algorithm identified by the algorithm code of the key ID tag;
storing the first calculated target ID in a database as an active first calculated target ID;
reading an object ID tag having an object target ID at an exit of the predetermined area;
the entrance and the exit to the predetermined area being an identical location or at least two different locations within the predetermined area;
comparing, by the central control system, the object target ID to all active calculated target IDs stored in the database; and
upon determining the object target ID is associated with an active calculated target ID in the database, entering a notification state.

Abstract
A system and method of loss prevention using a pair of ID tags is disclosed. The user or owner of the protected object can dynamically create a security perimeter by using key ID tag and object ID tag pair. An object ID tag is either embedded in or attached to a protected object. A key ID tag, which is in a handheld device, has protection to prevent unauthorized scan. The object ID tag information can only be obtained from key ID tag using preprogrammed algorithm. The area security system will be armed after reading and validating a key ID tag scanned by the user. If anyone takes protected object with object ID tag out of the area without proper key ID tag authentication, alarm will be triggered.

16. A system for detecting an object in a predetermined area comprising:
-
a plurality of ID tags comprising the object ID of an object ID tag bearing an object target ID and the key ID of a key ID tag bearing a source ID and an algorithm code, wherein the algorithm code identifies an algorithm for calculating a target ID from an algorithm database; at least one ID reader at an entrance of the predetermined area; and a central control system having a processor and in communication with the at least one ID reader, the central control system being associated with ID database; and wherein the at least one ID reader reads an ID tag of the plurality of ID tags; and upon a determination by the central control system that the ID tag that was read by the at least one ID reader is the key ID tag, the central control system calculates a first calculated target ID based on the source ID in accordance with the algorithm identified by the algorithm code of the key ID tag; and wherein the central control system stores the first calculated target ID in the ID database as an active first calculated target ID; and wherein the at least one ID reader reads the object target ID of the object ID tag at an exit of the predetermined area;
the entrance and the exit to the predetermined area being an identical location or two different locations within the predetermined area; andwherein the central control system compares the object target ID read by the at least one ID reader to all active calculated target IDs stored in the ID database; and upon a determination by the central control system that the object target ID read by the at least one ID reader is associated with one of the active calculated target IDs in the ID database, the central control system enters a notification state. - View Dependent Claims (17, 18, 19, 20, 21)
