Secret image sharing is a technique to protect the sensitive data. Secret image sharing combined with steganography and transform domain improves authentication ability. The primary objective of the paper is to design a novel algorithm for hiding the secret data in the transform domain. The underlying concept is based on the discrete wavelet transform. A technique comprising of Haar filter and wavelet based method is described for the secret image sharing. The discrete wavelet transform is used to embed the secret into the cover image and the inverse transform is used to recover the secret. The proposed technique provides robustness, better image quality and authentication ability. The stress is laid to improve the authentication ability of the secret image. The results have been compared with the state-ofthe-art technique and the outcomes shows that the results are very promising. The system is intended to assist the programmers to give a second thought so that the data can be transmitted secretly.
