Abstract: In this paper a new image encryption and decryption is proposed by using wavelet Packet decomposition. Data hiding is also embedding in the encrypted image. In the process of encryption original image is wavelet decomposed; further security can be achieved by rotational transform of the pixels that is the pixels are rotated after decomposing using wavelet transform. The data to be hided is embedded after rotational transform of the image; the resultant image is encrypted image with data hiding .The data recovered from data hided image by using inverse data hiding after the decrypt the image by inverse rotational transform and inverse wavelet decomposition. This encryption and data hiding technique is efficient technique for secure image and data transmission.

Keywords: Encryption, Rotational Transformation, Data hiding, and Decryption.
