DWT+LSB-based fragile watermarking method for digital Quran images

Abstract

In this digital era, the authenticity of digital documents can be doubtful because it may suffer from tampering activity. Looking into Muslim community, the most important book/scripture is the Holy Quran. The Muslim community has put great efforts to ensure the authenticity of the printed Holy Quran. However, such effort is not accompanied for digital Holy Quran. In this paper, we propose a fragile watermarking method to preserve the authenticity of the digital Holy Quran. The Proposed method is considered as fragile watermarking method, which works on wavelet and spatial domains of digital Quran images. The authentication bits are embedded into each block of wavelet-transformed image. Then, the least significant bits of pixels are considered to embed another authentication bits. The experimental results show that the watermarked image is imperceptible and fragile to the common attacks.
