Blind Digital Watermarking of Integer Wavelet Transform

Abstract:

In the light of JPEG compression attack, a blind digital watermarking algorithm of integer wavelet transform is proposed in this paper. Before the watermarking image is embedded, the cover image is decomposed by integer wavelet transform, and the binary watermarking image is scrambled to enhance its security. The scrambled digital watermarking is embedded into the cover image by means of modulo operation and modification of the integer wavelet transform coefficients of the cover image. The digital watermarking is extracted only by means of the modulo operation of the integer wavelet transform coefficients of the watermarked image and threshold ruling, and not depending on the original cover image. The experiments have shown that the blind digital watermarking algorithm can strongly resist JPEG compression attack.
