 INTRODUCTION  Data hiding is the process of embedding

information into a host medium. For instance, image and video data hiding

share many common points; however video data hiding necessitates more complex designs as a result of the additional temporal dimension.

Data hiding in video sequences is performed in two major ways: bitstream -level and data-level.

ABSTRACT

Video data hiding is still an important research topic due to the design complexities involved.

We propose a new video data hiding method that makes use of erasure correction capability of Repeat Accumulate codes and superiority of Forbidden Zone Data Hiding.

Selective embedding is utilized in the proposed method to determine host signal samples suitable for data hiding.

FORBIDDEN ZONE DATA HIDING (FZDH)

FZDH which is defined as the host signal range where no alteration is allowed during data hiding process.

FZ to adjust the robustness-invisibility trade-off.It contains Framework

Selective Embedding

Block Partitioning

Erasure Handling

Frame Synchronization Markers

ROBUST

The word robust, when used with regard to computer software, refers to an operating system or other program that performs well not only under ordinary conditions but also under unusual conditions that stress its designers' assumptions.

System Description

Existing System

Proposed System

EXISTING SYSTEM

• Least significant bit(LSB) replacement.

• wavelet domain.

• Least significant bit (LSB) is the simplest form of Steganography .

• LSB is based on inserting data in the least significant bit of pixels, which lead to a slight change on the cover image that is not noticeable to human eye and not easy to crack.

PROPOSED SYSTEM

Data hiding in video sequences is performed in two major ways:

Bit stream-level and Data-level.

In this paper, we propose a new block-based selective embedding type data hiding framework that encapsulates Forbidden Zone Data Hiding (FZDH)

MODULES Input module Watermark embedding Authenticator Watermark Spread Spectrum Watermarked content

MODULES DESCRIPTION

Input Module : It must be compatible with various document formats,

so that the user can be able to use any formats to hide the secret data.

Watermark embedding :Watermarking is a technology for embedding various types

of information in digital content.

Authenticator Watermark : In this module we encrypt the data

embedded image. The purpose of authenticator watermark of a

block is invariant in the watermark embedding process.

Spread Spectrum:We flip an edge pixel in binary images is

equivalent to shifting the edge location horizontally one pixel and vertically one pixel.

Watermarked content The watermarked content is obtained by

computing the inverse for the main processing block to reconstruct its candidate pixels.

Module I/O:

Module Input: We give original content as input with

watermark data embedding. We view flipping an edge pixel in binary images as shifting the edge location one pixel horizontally and vertically.

Module Output: The output of the project is we reconstruct

the pixel horizontally and vertically .we can see the original watermarked data and embedding content.

 

ENCRYPTION MODULE

Encryption module consists of• Key file, • Browse button, • Cover file, • Forbidden Zone Data Hiding Technique.

DECRYPTION MODULE

Reverse of Encryption module • Key file• Encrypted cover file • Extract button • Message displayed

IMPLEMENTATION

Implementation is the stage of the project when the theoretical design is turned out into a working system.

 The implementation stage involves careful planning, investigation of the existing system.

It’s constraints on implementation, designing of methods to achieve changeover and evaluation of changeover methods.

ADVANTAGES

User cannot find the original data.To increase the Security .To increase the size of stored data. We can hide more than one bit.

CONCLUSION In this paper, we propose a new video data hiding

framework that makes use of erasure correction capability of RA codes and superiority of FZDH.

The method is also robust to frame manipulation attacks via frame synchronization markers.

The framework is tested with MPEG-2, H.264 compression, scaling and frame-rate conversion attacks.

Typical system parameters are reported for error-free decoding.
