A conceptual design of genuine Halal logo detector

Due to the lack of proper act and legislation on the Halal enforcement, the Halal logo is often being exploited by some manufacturers who simply put the Halal label on their products without using the genuine one. This unlawful action creates confusion to consumers and causing them to question the validity of some of the products that are claimed to be halal. To overcome the problem, this paper presents a conceptual design of Halal logo detector that can be used to validate the Halal logo status printed on products. Two approaches are proposed in this conceptual design; the two-dimensional (2D) barcode and the ultraviolet (UV) hidden image of hologram approach. Two kind of 2D barcode such as PDF 417 and QR code are chosen based on their capability in data storage, high security, cost effective and applicability of the designed system. The physical layout of the detector is also designed so that it can be conveniently installed and used by consumer in the supermarket.
