ALSB teganalysis Algorithm Based on ImageWavelet Detail Information
According to the characteristic of which LSB steganography can influence the image wavelet detail information
this article presents the definition of images
with wavelet detail information and the wavelet detail information energy. We calculated the wavelet detail information energy of carrier image according secrete image
and estimated LSB steganography rate using two image wavelet detail information energy. The experiment proved that this method is efficient in estimating LSB steganography when the embedding rate is not too small.
