Abstract	Based on the increased awareness towards digital rights in commercial activity, the internet and media demands protection to enhance security. In this paper, predicated level of reversible watermarking scheme for image integrity and tamper detection or localization aspect. The proposed integrity analysis process is based on the region of interest watermarking with signatures and the use of alpha channel. Also integrity is analyzed at three distinct levels, which are used for the detection of modification, modified location and forensic analysis respectively. Behind this a digital watermark with 2D Barcode is a widely interesting research in the security field. Here this paper proposes a matrix barcode with the three level image watermarking using QR code and digital signature to verify image copyrights. A new watermarking method via the use of alpha channel is proposed. The alpha channel is used for controlling the transparency of the image. In proposed watermarking framework, it allows a user with an appropriate hash function SHA to verify the authenticity, integrity & ownership of an image. It is used as a metric in localization of tampered regions. The schemes successfully localize attack. The analysis scheme has shows high fidelity and is capable of localizing modified regions in watermarked image or localization of tampering. Mainly the channel watermarking can added to make system more robust to detect tampering attacks. Sole Purpose is to verify the integrity i.e. tamper verification.
