DWT (discrete wavelet transform) based watermark system

In this paper a DWT (discrete wavelet transform) based watermarking system is proposed. The proposed embedding system changes coefficients. The extracting system rebuilds thresholds according to various attacks and decides a watermark bit from the least distorted coefficient. A new measure to detect the uniqueness of watermark is also proposed.
