Abstract
Digital watermarking is a process whereby arbitrary information is encoded into an image in such way that the additional payload is imperceptible to the image observer. In the modern era, providing authenticity is becoming increasingly important as more of the world’s information is stored as readily transferable bits. Halal is an Arabic word which means lawful or permissible by Islamic laws. Halal logo is an image given by JAKIM to companies that have been issued Halal certificates. The companies need to produce the logo on their product packages and it is optional to display the halal logo on their websites. However, the Halal logo in the digital form used is not specific to one company and they can simply copy and alter it from other sources. Hence this matter causes the confusion on ensuring the authenticity of the Halal logo displayed on the websites of companies. Thus, a prototype applying watermarking using spread spectrum technique is developed to ensure authenticity of the Halal logo. This prototype has successfully embeds the watermark in the Halal logo image and several tests were done to ensure the system is working. Comparisons between texts files, images, sizes and histograms are conducted. In conclusion, by applying watermarking in Halal logo, the authenticity of it is assured and it is hoped to discourage and probably prevent people or companies to claim their product as Halal without receiving the Halal certification.
