A Review on Spatial & Transform Domain Digital Watermarking Techniques

Charu Kavadia, Arpita Lodha

Abstract


This paper presents a review on different Domain digital watermarking techniques and their properties. The watermarking is a
method of embedding objects into cover image for authentication of image. The important challenge during watermarking is to minimize
the distortion in cover image while maintaining the security of watermark against attacks. Presently two main methods are available for
watermarking one is spatial domain and other is transformed domain, both methods have their relative advantages and disadvantages and
should be selected according to the application specific requirements. This paper presents generalized reviews of both techniques.

 

Keywords: Watermarking, Spatial Domain Processing, Transform Domain Processing.
