Original message is converted into cipher text by using secret key and then hidden into the LSB of original image. The proposed system provides audio-video crypto stegnography which is the combination of image steganography and audio steganography using Forensics Technique as a tool to authentication. The main aim is to hide secret information behind image and audio of video file. As video is the application of many still frames of images and audio, we can select any frame of video and audio for hiding our secret data. Suitable algorithm such as LSB is used for image steganography suitable parameter of security and authentication like PSNR, histogram are obtained at receiver and transmitter side which are exactly identical, hence data security can be increased. His paper focus the idea of computer forensics technique and its se of video steganography in both investigative and security manner. Emphasis; do not underline. Pure Steganography is outlined as a hand system the exchange of a cipher isn't required like a stego key. There's 2 input, carrier object and message object. The hand calculation is used to implant message object onto transporter object [3]. The first criteria for this embedding is not any outsider spectator will see, listen or suspect concerning the message. It got to be exist mystery. Distinctive kind of item may be utilized as transporter and message object. 735 Bhushan Patole, Ashok Shinde, Mohit Bhatt, Prof. Pallavi Shimpi

2 It may be Image, Text, sound and video. However it cannot send giant information through this methodology [2] Steganography is that the methodology of activity any secret info like text and image, and passwords audio behind original cowl file. Cipher text by mistreatment secret key so hidden into the LSB of original image is regenerate into Original Message [6]. The audio-video cryptostegnography is gifting in planned system that is that the combination of image steganography and audio steganography mistreatment Forensics Technique as a tool to authentication [1]. The most aim is to cover secret info behind image and audio of video file. As several still frames of pictures and audio square measure applications of video file, it will choose any frame of video and audio for activity our secret information. Appropriate [5] algorithmic rule like AES is employed for image steganography appropriate parameter of security and authentication therefore information security may be multiplied. And for information embedding, use 4LSB algorithmic rule [4]. In this work, we tend to planned 2 reversible information activity (RDH) strategies by exploiting the synchronization of audio and video streams in MP4 instrumentation. The primary methodology achieves information activity by moldering sample count within the frame box. The second methodology manipulates to compress the particular video size with facilitate of compression and de-compression techniques. The benefits of the planned strategies embrace quick hiding/ extracting information and changeableness. Additionally, the planned strategies generate outputs that square measure MP4 kind at compliant and that they may be decoded by the quality video systems. MATHMATICAL MODEL Let S is the Whole System Consist of S = {I, P, O}. Where, I = input I = {U, AF, VF, A, B} U = User U = {u1, u2,..un} AF = Audio File. VF = Video File. A = Variable a. B = Variable b P = Process P ={I, F,} F = Functions. F = {VR, VW, Bit and, wavread, fopen } VR = Video Reader. VW = Video Writer. PROCEDURE: Selecting Audio Video File: 1. Select any available.avi audio-video file, behind which user want to hide data. 2. Separate audio and video from selected audio-video file using available software Easy Audio-Video Separator. 3. Save audio file as.wav file, this is the original separated audio file. 736 Bhushan Patole, Ashok Shinde, Mohit Bhatt, Prof. Pallavi Shimpi

3 Video Steganography: (At transmitter side) 1. Select original video.avi file. Read the file using Video Reader Function. 2. Collect all frames structure in one variable using mov function. 3. Read that structure. Play video using 'movie' function. 4. Accept one of the frame no. from user, behind which an authentication image is to be hidden. 5. Read that frame and store it in variable 'a'. 6. Select one of authentication image read that image and stores it in variable `b'. 7. To extract MSB of frame, bitand frame with 240 using function 'bitand'. 8. To extract MSB of authentication image, bitand image with 240 using function `bitand'. 9. Reverse the place of MSB of authentication image to LSB by dividing each element by Reshape the image bits into one row. 11. This reshaped row vector of authentication image data is embedded on the frame matrix, by adding each row vector bits to last 4 bits of frame bits. 12. This forms a stego frame, overwriting this stego-frame with original video file create stego-video file. 13. Using Video-Writer' function create new stego video file, in which authentication image is hidden. 14. Close the file. Creating Stego Audio File: 1. Combine stego audio and stego video file using Cute audio video merger. 2. This forms the stego audio-video file at transmitter side which has hidden text and image in it. Authentication: 1. After transmission the stego audio-video file obtained at receiver side. 2. Read the stego audio video file, stores the data in one variable al. 3. Select the frame no. The frame no. should be same at transmitter and receiver side, then only the authentication process start else it gets terminated. 4. To recover the authentication image from the selected frame bland the frame data with 15 using 'bitand' function. 5. Authentication image data is available at LSB of frame is recovered. It is in row vector. 6. Reshape the row vector data into matrix using 'reshape' function. 7. Select the authentication image at receiver side. Compare recovered authenticated image with the selected image. 8. If both the images matched, then only user can recover the text behind audio else process is terminated. Audio Recovery: 1. Audio file is read using function 'wavread', sample data is store in 'y'. 2. Open this stego audio file in re ad mode using function 'fopen'. 3. Read wave file's first 40 bytes of header using 'tread' function and store it in a variable 'header'. 4. Then read all its data after 40th byte using same function and store it in 'dtal' variable. 5. Close file using if closes function. 6. Recover the size of identity key from LSB of.wav file. Recover identity key from further LSB bits of.wav file. 737 Bhushan Patole, Ashok Shinde, Mohit Bhatt, Prof. Pallavi Shimpi

4 7. Accept identity key from user and compare entered identity key with recover identity key. If both the keys matched then only user can recover the hidden text else processes will be aborted. 8. As identity key is matched recover the size of message from further LSB bits of.wav file. Recover the message. 9. Secrete text is recovered. OUTPUT: Secrete text is recovered and received at destination. RELATED WORK A. Existing work: In previous, cryptography and steganography is used for encryption of data and provides data security. Actually term cryptography provides privacy and steganography is the art and science of communicating in an approach which hides the existence of the communication. The steganography hides the message so it cannot be seen; cryptography jumble a message so it cannot be understood. Cryptography systems can be broadly classified in to symmetric-key systems that use a single key that both the sender and the receiver have, and public key systems that use two keys, a public key known to every one and a private key that only the recipient of messages uses. The subject is that study techniques for decoding cipher messages and detecting hide messages are called cryptanalysis and steganalysis. Steganography is not the same as cryptography, data hiding techniques have been widely used to broadcast of hiding secret message for long time. Assuring data security is a big dispute for computer users. Even though both methods provide protection, to add multiple layers of security it is always a good practice to use cryptography and stegnography together. B. Proposed work: In this paper, info security victimization information activity audio video steganography with the assistance of pc rhetorical techniques give higher activity capability and security. Computer rhetorical technique at receiver facet to cross check the protection parameters and providing authentication at receiver facet thus our information is triple secured. We area unit activity encrypted information victimization steganography and Cryptography behind elite frame of video victimization 4LSB insertion methodology and audio victimization section secret writing formula transmitter facet. Finally projected work relating to compression and de-compression technique use for to compress the particular video size with none disturbance of video and conceal information. Information security victimization information activity audio video stegnography with the assistance of pc rhetorical techniques provides higher activity capability we've worked on activity image Associate in nursing text behind video and audio file and extracted from an AVI file victimization four least important bit insertion strategies for video steganography and section secret writing audio stegnography. We area unit activity encrypted information victimization stegnography and cryptography behind elite frame of video victimization 4LSB insertion methodology. SYSTEM ARCHITECTURE In our system Stegnography is that the methodology of activity any secret info like positive identification, text and image, audio behind original cowl file. Original message is reborn into cipher text by mistreatment secret key and so hidden into the LSB of original image. In this system provides audio-video crypto-stegnography that is the combination of image steganography and audio steganography using Forensics Technique as a system to authentication. The main aim is to cover secret info behind image and audio of video file. As video is that the application of the many still frames of pictures and audio, we are able to choose any frame of video and audio for activity our secret information. 738 Bhushan Patole, Ashok Shinde, Mohit Bhatt, Prof. Pallavi Shimpi

5 Suitable rule like LSB is employed for image steganography appropriate parameter of security and authentication like PSNR, bar chart are obtained at receiver and transmitter aspect that are specifically identical, and compression and de-compression techniques used for to compress the video size, therefore information security are often inflated. This paper focuses the concept of pc forensics technique and its se of video steganography in each inquiring and security manner. Fig. 1: System Architecture IMPLIMENMTATION Information security using data hiding audio video stegnography with the help of computer forensic techniques provides better hiding capacity we have worked on hiding image and text behind video and audio file and extracted from an AVI file using 4 least significant bit insertion methods for video steganography and phase coding audio stegnography. We are hiding encrypted data using stegnography and cryptography behind selected frame of video using 4LSB insertion method. Finally projected work relating to compression and de-compression technique use for to compress the particular video size with none disturbance of video and conceal information. ALGORITHM FOR HIDING DATA IN FREME: AES encryption algorithm: AES is based on a design principle known as a substitution- permutation network, and is fast in both software and hardware. Unlike its predecessor DES, AES does not use a Feistel network. AES operates on a 4 4 column-major order matrix of bytes, termed the state, although some versions of Rijndael have a larger block size and have additional columns in the state. Most AES calculations are done in a special finite field. 739 Bhushan Patole, Ashok Shinde, Mohit Bhatt, Prof. Pallavi Shimpi

6 We use 128 bit key for an AES cipher which specifies the number of repetitions should be 10 cycles transformation rounds that convert the input, called the plaintext, into the final output, called the cipher text. Each round consists of several processing steps, each containing four similar but different stages, including one that depends on the encryption key itself. A set of reverse rounds are applied to transform cipher text back into the original plaintext using the same encryption key. ALGORITHM FOR HIDING DATA IN VIDEO: 1. Least Significant Bit (LSB) based steganography The simplest and most common type of steganography is LSB (least significant bit). The one s bit of a byte is used to encode the hidden information. Suppose we want to encode the letter A (ASCII 65 or binary ) in the following 8 bytes of a carrier file. ALGORITHM FOR MANAGE SIZE OF VIDEO: 1. Compression De-Compression Compression technique used for to compress the actual video size without any disturbance. De-Compression technique used for to de-compress (opposite to compression) the actual video size. RESULTS CONCLUSION AND FUTURE SCOPE Information security using data hiding Audio video steganography with the help of computer forensic tech provide better hiding capacity and security. In this paper we study the data security exploitation data concealing Audio video steganography with the assistance of pc rhetorical school offer higher concealing capability and security. Steganography may be classified supported several criteria and one in all them relies on the sort of canopy media. This paper conferred a review add video steganography ways its major varieties and classification that are planned within the literature throughout previous couple of years. As video could be a bunch of pictures combined with audio, all existing image and audio stenographic techniques area unit applicable to video steganography. Execs and cons of various steganography algorithmic programs were conjointly mentioned. 740 Bhushan Patole, Ashok Shinde, Mohit Bhatt, Prof. Pallavi Shimpi
