Abstract
For the purpose of security, Data hiding process embeds data
into digital media. Digital image is one of the best media to
stores data. It provides large capacity for hiding secrets
information which results into the stego-image imperceptible
to human vision, a novel Steganographic approach based on
data hiding method such that pixel-value differencing. In
existing approach different techniques are used such as LSB
substitution method, hamming, pixel indicator based method
etc. In LSB, there are constraints on image size. In proposed
system, Huffman, zigzag and OPAP methods are used to
overcome the limitation of the size and provide both high
embedding capacity and outstanding imperceptibility for the
stego-image. The text data can be embedded into the cover
image. Huffman code is to compression the secret messages
before sending it to the receiver. Zigzag scanning to select the
pixels that will secret messages is hidden. To enhance the
quality of the stego-images optimal pixel adjustment process
(OPAP) is used. It also minimizes embedding error. The aim
is to provide better security with high embedding capacity and
a better stego-image quality than the existing system.
