Abstract:

In order to solve the problem of extracted-bit errors in existing joint reversible data hiding methods for encrypted images and achieve a higher embedding capacity,a novel algorithm with self-correction and privacy protection is proposed.Before image encryption,the algorithm embeds self-correcting data generated by preprocessing into the down-sampling pixels of the image reversibly,and then data can be embedded into the encrypted image by reserving or flipping certain least significant bits of non-sampled pixels in each group.Experimental results show that the proposed algorithm greatly increases the embedding capacity,and that the quality of the decrypted marked image is fine.This technology can be used in military,medical,cloud services and other fields.

Key words: reversible data hiding, integer transformation, encryption, interpolation
