| Research Abstract |
This work treats the digital watermarking with considering the false positive probability and bit-pattern embedding. We propose an iterative embedding algorithm of watermarking signals which are generated by a secret key. Moreover, in the detection, the correlations between the watermarked coefficients and watermark signals are computed by using the secret key. In the experiment, we show the detection results with specified false positive probability and the bit-pattern recovery, and the comparison ofthe proposed method against JPEG compression, scaling down and cropping.
