Abstract
This paper presents an integer wavelet-based invertible high-capacity data-hiding method for digital images. According to the frequency sensibility result of HVS study, high capacity (up to 1/2 of the data volume that original image occupies) secret information can be hidden into the least significant bit-planes of wavelet coefficients. Histogram modification is introduced to meet overflow/underflow in inverse wavelet transformation. As multi-resolution and correlation decomposition, which are the superiority of wavelet decomposition, are fully employed, this method can achieve both high-capacity and low distortion. The proposed data-hiding method is applied to E-government and good result is achieved.
