Abstract — We propose a new image steganogrphy method to verify whether the secret information had been deleted, forged or changed by attackers. The proposed method hides secret information into spatial domain of digital image. In this paper, we can verify the integrity from extracted secret information using the AC coefficients of the discrete cosine transform (DCT) domain.
