Steganography is a science of hiding messages into multimedia documents. In steganography, there is a technique in which the least significant bit is modified to hide the secret message, known as the Least Significant Bit (LSB) steganography. LSB encryption is used for hiding information in multimedia documents. After LSB encryption the multimedia documents are compressed by using Discrete Wavelet Transform (DWT) technique and for the retrieval of the original, the image is decompressed by Inverse Discrete Wavelet Transform (IDWT).
