Reversible watermarking scheme for image authentication in frequency domain
Currently any digital media can be easily modified. As a measure to ensure authenticity of the media in question, watermarks may be used. However, for a specific media (military or medical imagery) modifications introduced by watermarking process are not acceptable. Reversible watermarking, that allows to restore exact original image, is designed for this usage. In this paper semi-blind reversible pixel-wise image authentication framework is proposed. The scheme allows us to authenticate and locate tampered pixels. Also exact recovery of the original image is possible
