Robust video data hiding using forbidden data hiding
- 1. ROBUST VIDEO DATA HIDING USING FORBIDDEN ZONE DATA HIDING AND SELECTIVE EMBEDDING 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. This method also contains a temporal synchronization scheme in order to withstand frame drop and insert attacks. The proposed framework is tested by typical broadcast material against MPEG-2, H.264 compression, frame-rate conversion attacks, as well as other well-known video data hiding methods. The decoding error values are reported for typical system parameters. The simulation results indicate that the framework can be successfully utilized in video data hiding applications. EXISTING SYSTEM: In special domain, the hiding process such as least significant bit(LSB) replacement, is done in special domain, while transform domain methods; hide data in another domain such as 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. Since this method can be easily cracked, it is more vulnerable to attacks. LSB method has intense affects on the statistical information of image like histogram. Attackers could be aware of a hidden communication by just checking the Histogram of an image. A good solution to eliminate this defect was LSB
- 2. matching. LSB-Matching was a great step forward in Steganography methods and many others get ideas from it 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) By means of simple rules applied to the frame markers, we introduce certain level of robustness against frame drop, repeat and insert attacks. o ADVANTAGES User cannot find the original data. It is not easily cracked. To increase the Security . To increase the size of stored data. We can hide more than one bit. HARDWARE REQUIREMENTS • SYSTEM : Pentium IV 2.4 GHz • HARD DISK : 40 GB • MONITOR : 15 VGA colour • MOUSE : Logitech. • RAM : 256 MB • KEYBOARD : 110 keys enhanced. SOFTWARE REQUIREMENTS • Operating system : Windows XP Professional

The main module are one is encryption module and the decryption module. These two modules are the main core for the application. MODULES Input Module : ENCRYPTION MODULE DECRYPTION MODULE DES Triple DES RSA Modules Description: Input Module: The Input Module is designed as such a way that the proposed system must be capable of handling any type of data formats, such as if the user wishes to hide any image format then it must be compatible with all usual image formats such as jpg, gif, bmp, it must be also compatible with video formats such as .avi, .flv, .wmf etc.. And also it must be compatible with various document formats, so that the user can be able to user any formats to hide the secret data. Encryption Module:
- 4. In Encryption module, it consists of Key file part, where key file can be specified with the password as a special security in it. Then the user can type the data or else can upload the data also though the browse button, when it is clicked the open file dialog box is opened and where the user can select the secret message. Then the user can select the image or video file through another open file dialog box which is opened when the cover file button is clicked. Where the user can select the cover file and then the Hide button is clicked so that the secret data or message is hidden in cover file using Forbidden Zone Data Hiding Technique. Decryption Module: This module is the opposite as such as Encryption module where the Key file should be also specified same as that of encryption part. Then the user should select the encrypted cover file and then should select the extract button so that the hidden message is displayed in the text area specified in the application or else it is extracted to the place where the user specifies it. DES: This module consists of same as Encryption and Decryption part using DES algorithm. The Data Encryption Standard (DES) is a block cipher that uses shared secret encryption. Triple DES: This module consists of same as Encryption and Decryption part using Triple DES algorithm. Triple DES is the common name for the Triple Data Encryption Algorithm (TDEA or Triple DEA) block cipher, which applies the Data Encryption Standard (DES) cipher algorithm three times to each data block. RSA:
- 5. This module consists of same as Encryption and Decryption part using RSA algorithm. RSA is the first algorithm known to be suitable for signing as well as encryption, and was one of the first great advances in public key cryptography. RSA is widely used in electronic commerce protocols, and is believed to be sufficiently secure given sufficiently long keys and the use of up-to-date implementations.
