Abstract
This paper presents a lossless data hiding method using integer wavelet transform. The modification of small coefficients of the high frequency subbands are used to embed data. We use the histogram modification to prepare enough space for data hiding. Data embedding is done by processing these selected coefficients of the modified subband histograms. We show that we can embed high capacity of data by applying multi-level integer wavelet decomposition and histogram modification. Experimental results show that our method outperforms the prior arts in terms of a larger pay-load.
