ABSTRACT This paper proposes a new image steganography scheme in order to hide a secret data in cover image uses the transform domain to increase its robustness and security. Curvelet transform is the new member of the evolving family of multiscale geometric transforms. Since it represents edges better than Wavelet, Curvelet transform offers an effective solution to the problems associated with image steganography using Wavelets and DCT (Discrete Cosine Transform). In this paper we were testing four different steganographic methods. The Radon Transform used in this paper for encoding the secret image to increase security. The software used in this paper is (Matlab V 7.0.4). The results obtained are in accordance with the expected predictions of the existing theory of Curvelet transform.
