Abstract EN
The image steganography systems use either the spatial domain or the frequency domain to hide the secret information.
The proposed technique uses spatial domain technique to hide secret information in the frequency domain.
The cover image is transformed using integer wavelet transform to obtain four subbands: LL, LH, HL, and HH.
Then, the PVD approach is used to hide the secret information in the wavelet coefficients of all the four subbands.
For improving the security of the hidden information, the proposed method first modifies the difference between two wavelet coefficients of a pair and then uses the modified difference to hide the information.
This makes extraction of secret data from the stego image difficult even if the steganography method fails.
The result shows that the proposed technique outperforms other PVD based techniques in terms of security of secret information and hiding capacity of cover image.
