HIDING TEXT DATA IN AUDIO SIGNALS USING 3BIT LSB TECHNIQUE AND DCT APPROACH

Steganography is that the limit and examination of encompassing lined messages during aperspective that no one, nearby the sender and foreseen beneficiary, interfaces the part withthe message, a kind of security through nonattendance of clearness. The present strategy ofAudio Steganography addresses extra camouflages on the picking of sound reports. The proposed system use 3 Bit LSB Stegnography to hide the text data into an audio signal. Proposed system is evaluated on various input data containing from various sources. The performance of the proposed system is also compared with the performance of existing system.
