An Effective Implementation Of LSB Steganography Using Dwt Techniques
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 is 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).By using LSB decryption
the hidden information is separated from the multimedia documents.
