Authentication of secret data using video and audio steganography with wireless transmission
Abhilasha Ramdas Bhagat, PG Student · 2015
Steganography is a science of covered writing in which the data is hidden in the carrier vessel .The carrier vessel can be image, audio ,video , text .The video have more hiding capacity to store more data than the rest of the vessel media. Various algorithm are available such as LSB substitution algorithm DCT algorithm ,SLSB algorithm ,etc .All of these algorithm have less hiding capacity moreover they are less secure and easily detectable by unauthorized users. BPCS algorithm (Bit plane complexity segmentation ) in which the image frame of video is decomposed into bit planes from LSB to MSB .The data is stored in complex area of the bit planes so the hiding becomes undetectable and moreover the capacity to store data increases.To increase more security the video steganography is combined with the LSB audio steganography.Both transmitting party and and receiving party is provided with the authorization key, thus the unauthorized user cannot access secret data without the authorization key .The level of hiding capacity is thus increased along with enhanced security level.
