  In this paper a self organized legal document/content authentication,
copyright protection in composite domain has been proposed without using any
external information. Average values of transformed red and green components in
frequency domain generated through wavelet transform are embedded into the blue
component of the color image matrix in spatial domain. A reverse transformation
is made in RG matrix to obtain embedded image in association with blue
component in spatial domain. Reverse procedure is done during decoding where
transformed average values are obtained from red and green components and
compared with the same from blue component for authentication. Results are
compared with existing technique which shows better performance interns of
PSNR, MSE & IF.
