This paper proposed novel approach of image steganography for text embedding in spatial domain. In the proposed embedding the message is dumped into the image with reference to a random generated key, based on this key the extraction of text is done from the image. So this method is a highly secured from eavesdropping and highly complex to identify the text data in the image and retrieving the text message from the message is also a resilient process. The extraction is only possible when the key is known.

Steganography is one of the commanding and commonly used methods for embedding data. Realizing steganography in hardware supports to speed up steganography. This work realizesthe novel approach for generation of Key, for hiding and encoding processes of image steganography using LSB and HAAR DWT.The data embedding process is realized with seven segment display pattern as a secret key with various sizes using HAAR DWT and LSB. Maximum hiding effectiveness is also attained from this work. The same is implemented in hardware using reconfigurable device Field programmable gate array to improve the speed, area and power. The proposed work is also evaluated improved PSNR using MATLAB.
