Abstract

This paper presents a semi-fragile watermarking technique capable of both authenticating and recovering an image. The proposed approach offers choice of embedding two watermarks and is able to detect and differentiate the modifications applied on the watermarked image. Semi-fragility makes the scheme tolerant against JPEG lossy compression. While, recovery attribute makes it suitable for video surveillance and remote sensing applications.
