Text Steganography is a field of hiding text messages into multimedia (e.g. image) documents. In this method we apply DWT on input image to divide it into four sub-band. We will work on low frequency band. After hiding the text information the picture has been compressed for reducing the memory. The method which is used for the compression is Discrete Wavelet Transform (DWT), for recovery of the original image which we use for the Inverse Discrete Wavelet Transform (IDWT) and to get a secret code back which we use Decryption technique. A complete set of experiments is implemented to explain proposed method's applicability and assess the worth of its performance in resistance to Peak signal noise ratio and NPCR achieve the reason of information hiding with the use of secret bit of information by replacing the random noise, with the lowest plane of embedding secret information in order to avoid the noise and the security attacks, making use of the redundancy. The results shows that the proposed algorithm has a good hidden invisibility, very good security and good strength for a plenty of hidden attacks.
