1. NEW CHANNEL SELECTION RULE FOR JPEG STEGANOGRAPHY
OBJECTIVE:
To improve higher security performance and reducing errors, the main
role of this project as present a new channel selection rule for Joint
Photographic Experts Group Steganography.
PROBLEM DIFINITION:
The composite signal is subject to video lossy compression to become.
The message should survive the video lossy compression and can be identically
extracted from. This robustness constrain should have low distortion effect on
the reconstructed video as well as low effect on the data size (bit rate). Given
that can be identically extracted, in this paper; we use two metrics to evaluate
data-hiding algorithms in compressed video which are:
1. Increase in data size: representing the overhead price paid for the
embedded data;
2. Drop in the reconstruction quality: this reconstruction is with
quality loss than that without data hiding and is denoted by and
expressed as the PSNR difference which is as well that of the
quantity of the relative error and for P- and B-frame, respectively.

2. This paper deals with data hiding in compressed video. Unlike data
hiding in images and raw video which operates on the images themselves in the
spatial or transformed domain which are vulnerable to steganalysis, we target
the motion vectors used to encode and reconstruct both the forward predictive
(P)-frame and bidirectional (B)-frames in compressed video. The choice of
candidate subset of these motion vectors are based on their associated macro
block prediction error, which is different from the approaches based on the
motion vector attributes such as the magnitude and phase angle.
A greedy adaptive threshold is searched for every frame to achieve
robustness while maintaining a low prediction error level. The secret message
bit stream is embedded in the least significant bit of both components of the
candidate motion vectors. The method is implemented and tested for hiding data
in natural sequences of multiple groups of pictures and the results are evaluated.
The evaluation is based on two criteria: minimum distortion to the reconstructed
video and minimum overhead on the compressed video size. Based on the
aforementioned criteria, the proposed method is found to performwell and is
compared to a motion vector attribute-based method from the literature.
EXISTING SYSTEM:
The Existing System contained only steganography process for data
transfer without any security prediction. In this system developed new channel
selection method for data hiding, but it didn’t use any advanced methods and
factors for data hiding. So that, It produce lot of errors in the timing for image
decompress.

3.  Less Security
 High amount of Perturbation Errors
 Very difficult for Image Decompression
PROPOSED SYSTEM:
In proposed system contain advanced Perturbed Quantization rule for
data hiding. The process of data hiding as follows,
 LSB Algorithm
 Embedding data, which is to be hidden, into an image requires two files.
 The first is an innocent looking image that will hold the hidden
information, called the cover image.
 The second file is the message – the information to be hidden
ADVANTAGES:
 Minimal detectable distortion
 Higher security performance
ALGORITHM USED:
1. LSB (Least Significant Bit)
2. AES (Advanced Encryption Standard)
