ABSTRACT: Recently, several digital watermarking techniques have been proposed for
hiding data in the frequency domain of moving image files to protect their
copyrights. However, in order to detect the water marking sufficiently after
heavy compression, it is necessary to insert the watermarking with strong
intensity into a moving image, and this results in visible deterioration of the
moving image. We previously proposed an authentication method using a discrete
wavelet transform for a digital static image file. In contrast to digital
watermarking, no additional information is inserted into the original static
image in the previously proposed method, and the image is authenticated by
features extracted by the wavelet transform and characteristic coding. In the
present study, we developed an authentication method for a moving image by using
the previously proposed method for astatic image and a newly proposed method
for selecting several frames in the moving image. No additional information is
inserted into the original moving image by the newly proposed method or into
the original static image by the previously proposed method. The experimental
results show that the proposed method has a high tolerance of authentication to
both compressions and vicious attacks.
