Image Watermarking Technique for Digital Al-Quran based on Fibonacci Transform via DWT

Abstract

Advent growth in information and communication technologies has accelerated the needs to secure digital media. Demands for digital media when on the move urged Quran readers to install the Quran mobile apps on their device. However, there is no secure mechanism to legalize its content credential. On the other hand, mobile developer finds difficulty in getting access to readily authentic Quran database sources. Malaysia government has introduced Smart Quran mobile apps without any counterfeit protection. Correspondingly, the contents are vulnerable to hacking, falsification which consequently endangering Islamic institutional prestige. There is also a lack of credible authorization institutions to verify authenticity of the digital Quran that could possibly deviate the Muslim faith by reciting falsified content and meaning. To fill the void, this paper explores the utilization of an image watermarking to preserve the Quran digital image. The study presents new blind RGB image watermarking using Fibonacci Transform via Discrete Wavelet Transform (DWT) and manipulates the R component of the Al-Quran image. The second level of LL decomposition of the cover image will then be substituted by the Fibonacci-transformed watermarked version. DWT embedding is achieved through alpha blending technique. Final watermarked image is obtained once RGB conversion is performed. The efficiency of the method is assessed towards 10 samples. Verification is conducted via the extraction of the endorsed license image. The results demonstrate enhanced robustness and imperceptibility with average PSNR and SSIM of 92.13 dB and 0.99 respectively. Forgery cases of digital Quran applications are therefore tackled.
