Abstract :
In this paper, a new digital watermarking algorithm is presented. In this algorithm, the watermark embedded in the image is a sinusoidal signal with a certain frequency. When detected, the extracted watermark is the input to a chaotic system in which the weak signal with the same frequency as system frequency parameter can be detected. Chaotic system are sensitive to certain signals and immune to noise at the same time, so the watermarking detection method based on a chaotic scheme has a good performance for distorted original watermark signal. Simulation results are provided to support this claim.
