Digital Forensics in Small Devices: RFID Tag Investigation

Karygiannis et al., (2007, pp. 2-15), the supporting customized business
logistics perhaps consists of “rules for automated inventory management,
procurement, shipping, receiving and billing”. Hence, the AS is mostly
based on enterprise database applications to support a variety of data
coming from multiple sources such as customers, suppliers, logistics service
providers and the like as the AS is intended to exist with or replaced the bar
code technology (Karygiannis et al., 2007). Thus, the AS deals with the
RFID tag data that complies with EPCglobal standards and is sometimes
referred to as EPC Information Services (EPCIS).
2.2.3.3 Network Infrastructure (NI)
The communication between the RF subsystem and enterprise subsystem is
facilitated by the network infrastructure which is made up of the
communication protocols, logical and physical topology of the RFID
network (Karygiannis et al., 2007).
2.3 BUSINESS SYSTEM OF STOCK MANAGEMENT SYSTEM
The Business System (BS) architecture of a RFID stock management system
consists of three entities, namely the Stock Item (SI), the Point of Sale (POS) and
the Business Information System (BIS). Each entity has sub-systems and services
that are required by the other entities. For example the SI requires RFID Tags, a
scanner, and services from POS and BIS. The POS requires a Transaction
Processing System (TPS), scanners (for cards, Tags and Chips), a Tag
attach/detach service and the services of SI and BIS.

The BIS requires software for data base/warehouse and the relevant build for
information management. In addition the services of SI are required for audit and
POS for updating the relevant stock values. The Business System consequently
