his paper presents a reversible data hiding method based on wavelet spread spectrum and
histogram modification. Using the spread spectrum scheme, we embed data in the coefficients of integer
wavelet transform in high frequency subbands. The pseudo bits are also embedded so that the decoder does
not need to know which coefficients have been selected for data embedding, thus enhancing data hiding
efficiency. To prevent the overflow and underflow, an efficient histogram modification method is developed
and utilized. Experimental r-his paper presents a reversible data hiding method based on wavelet spread spectrum and
