Error exponents for one-bit watermarking Conference Paper uri icon


  • Quantization index modulation (QIM) is a powerful host-interference rejecting method for data hiding. This paper applies QIM to one-bit watermarking and proposes a simple but powerful watermark detector. We derive lower bounds on the error exponents for the detector under a quadratic distortion constraint for the watermarker and additive white Gaussian noise attacks. These bounds are independent of the host-signal distribution and are substantially better than recently derived bounds for public (blind) spread-spectrum watermarking.
