Designing Privacy and Security Protection in RFID-enabled Supply Chain

RFID is an automatic identification system that uses radio frequency technology in product tags. The technology brings out the greater enhancement to synchronize the logistics flow and information flow. Unfortunately, it also introduces the great concerns on the privacy and security protection, not only on the individual use but also on the supply chain collaboration. This study proposes an on demand access control to protect the information flow in an RFID-enabled supply chain. The design considers the role in a supply chain as well as the media of carrying the information. A case study on garment industry will be provided for validation

A Relationship-Based Acess Control Model for On-demand Privacy and Security Entitlement in RFID-enable Supply Chains

RFID adoption in supply chains is both viable in gaining on-target end-to-end visibility and crucial to sustain competitiveness. RFID-based information flow will cut across partners in business chains that extended beyond borders. Privacy and security preferences (PSP) are manifested when supply chain parties are sharing (EPC-RFID-based) data to gain visibility. The role of each party cannot be singly used to determine the preference of either party to derive the necessary entitlement for the requesting party. The preference-based entitlement must ensure data sharing is privacy-protected and security-enforced. In this research, a Relationship-Based Access Control (ReBAC) model is proposed for on-demand privacy and security entitlement in RFID-enabled supply chains. The model includes two key concepts: on-demand preference and privacy and security scheme. Preference is governed by the two parties’ relationship, and the scheme is driven by the data dimensions (i.e., data sensitivity, data location and data ownership). RBAC is capable of addressing one party’s need to gain pre-determined permissions according to role assignment or activation. The relationship-based approach is on-demand, two-party, relationship-based preference to gain entitlement (for visibility services) with scheme-enabled privacy and security activation

Three Phases RFID Adoption: A Road Map to Success

Radio frequency identification (RFID) uses radio frequency technology for automated identification. The use of RFID brings the second source of information to enterprise management. It is said the second source is because, in the conventional approach, the information is shared among the various units through an integrated enterprise system. In this study, we define three layers of networks, i.e. Intranet, Extranet, and Internet, can be used to share RFID data and the adoption of RFID technology can be recognized into three phases: standalone adoption, supply chain adoption, and global adoption. Issues in each adoption will be address as well as road map to the success will be included

A novel method for measuring the extragalactic background light: Fermi application to the lobes of Fornax A

We describe a new method for measuring the extragalactic background light (EBL) through the detection of $\gamma$-ray inverse Compton (IC) emission due to scattering of the EBL photons off relativistic electrons in the lobes of radio galaxies. Our method has no free physical parameters and is a powerful tool when the lobes are characterized by a high energy sharp break or cutoff in their electron energy distribution (EED). We show that such a feature will produce a high energy IC `imprint' of the EBL spectrum in which the radio lobes are embedded, and show how this imprint can be used to derive the EBL. We apply our method to the bright nearby radio galaxy Fornax A, for which we demonstrate, using WMAP and EGRET observations, that the EED of its lobes is characterized by a conveniently located cutoff, bringing the IC EBL emission into the {\sl Fermi} energy range. We show that {\sl Fermi} will set upper limits to the optical EBL and measure the more elusive infrared EBL.Comment: ApJL, accepte
