Steganography is the art and science of hiding the
existence of information. In computer-based steganography,
several forms of digital media may be used as “cover” for hidden
information. Photos, documents, web pages and even MP3 music
files may all serve as innocuous looking hosts for secret messages.
In this paper, we generate a ECG signal of patient and hide this
ECG signal in the image of patient i.e. patient photo is used as a
cover for hiding the ECG signal. Steganography is done using the
Contourlet transform. To hide the data in image Singular Value
Decomposition (SVD) is used. The contourlet transform provides
higher correlation coefficient. The results are comparing with the
wavelet transform. The proposed system provides a better PSNR
value than the wavelet transform.
