In this paper, we investigate the use of a family of transform domains in embedding hidden data.A new date hiding scheme that is based a pair of unmatched orthogonal transforms has been developed. The hidden message signal is transmitted via the residual channel of two different parameterized slant transforms. The properties of residual channel of parameterized slant transforms are characterized and performance of proposed scheme have been analyzed and simulated. We also discuss on the performance of the scheme and basis selection.
