Abstract

The present study discusses a novel two layer technique for securing digital images. The two techniques used are visual cryptography (VC) scheme and int-to-int wavelet transforms (IWT). (2, 2) –VC scheme is used to split the secret image into two shares. The IWT is used to decompose the image into its sub bands and the secret image shares are stored in the HH band of the decomposition. Invisibly embedding image shares generated by the visual cryptography in the host image to provide authentication to the shares. The proposed scheme is compared with the traditional discrete cosine transform (DCT) for watermarking. The performance is measured by computing peak signal to noise ratio, mean square error and cross-correlation coefficient.
