ABSTRACT:
There is provided a digital watermarking detecting device that can accurately detect watermarking information weakened by an attack such as image cut-out, scaling or the like without increasing a calculation amount and a circuit scale. The digital watermarking detecting device includes an extractor10for extracting a signal of a specific frequency component from a watermarking embedded image, first orthogonal transformers11A,11B for calculating an orthogonally-transformed image of an extraction signal and an orthogonally-transformed image of a watermarking embedded image, amplitude adjusters12A,12B for adjusting the amplitudes of the two orthogonally-transformed images in accordance with the difference between the amplitude components of the two orthogonally-trans formed images, a compositor13for combining the two amplitude-adjusted orthogonally-transformed images, a second orthogonally-transformer14for subjecting the composite signal to orthogonal transformation to achieve a second orthogonally-transformed signal, and an estimator15for estimating the watermarking information on the basis of a peak appearing in the second orthogonally-transformed signal.
