Image steganography is an art of hidingimages secretly within another image. There are several ways of performing image steganography; one among them is the spatial approach.The most popular spatial domain approachof image steganography is the Least Significant Bit (LSB)method, which hides the secret image pixel information in theLSB of the cover image pixel information. In this paper aLSB based steganography approach is used to designhardware architecture for the Image steganography. TheDiscrete Wavelet Transform (DWT) is used here to transformthe cover image into higher and lower wavelet coefficientsand use these coefficients in hiding the secret image. thedesign also includes encryption of secret image data, toprovide a higher level of security to the secret image. Thesteganography system involving the stegno module and adecode module is designed here. The design was simulated,synthesized and implemented on Artix -7 FPGA. Theoperation hiding and retrieving images was successfullyverified through simulations.
