Abstract :
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.
