An Image Watermark Adding and Detection Method
This paper introduces the wavelet transform, and based on which brings forward a new computer doable method. When an image is processed by multi-level 2-dimension dispersed wavelet transform, we can get two data information: the low frequency and the high frequency, after that, we add some random data to the high frequency, and then reconstruct the image. When testing, we use the same wavelet decomposition method to detect the correlation between the high frequency and the random data. This method can be used to avoiding the image forgery.
