Research in the field of watermarking is flourishing providing techniques to protect copyright of intellectual property. Among the various methods that exploit the characteristics of the Human Visual System (HVS) for more secure and effective data hiding, wavelet-based watermarking techniques showed to be immune to attacks; adding the quality of robustness(More)
In this paper, a framework to hide privacy in video is proposed based on data hiding principals. A novel data hiding technique is proposed and implemented to hide the original frame into the in-painted one. The proposed hiding technique is carried out in the discrete wavelet transform domain of the cover video. The proposed technique is embedding video into(More)
Steganography is the field of research that provides innovative solutions to the problem of secure data communication. In this paper, a non-blind data hiding technique is proposed which is based on data fusion between both the cover and the secret images. The proposed embedding process is made in the Discrete Cosine Transform (DCT) domain of the cover(More)
