摘要：Steganography exploits the use of host data to hide a piece of information in such a way that it is imperceptible to human observer. Its main objectives are robustness, high payload, and imperceptibility. Digital images, videos, sound files, and other computer files can be used as carrier to embed the information. This paper deals with digital gray scale digital images, and presents a secure steganography scheme for hiding a larger size secret-image into smaller size cover- image. Arnold Transformation is performed to obtain scrambled secret image. Discrete Wavelet Transform (DWT) is performed on both host / cover image and secret image / information, and this is followed by alpha blending operation. The approach shows satisfactory results. Results show that proposed algorithm is highly secured with good perceptual invisibility
