چكيده لاتين :
A transform-based watermarking technique is
investigated in this study. The watermark signal is built by using
a chaotic map and then is embedded to cosine coefficients of the
scrambled host image. Experimental results confirm that the
watermarked signal is robust against a range of signal processing
and attacks which threatened a watermarking system.
