This document proposes a method for securing video transmission using steganography and cryptography. The method has three objectives: 1) To combine steganography and cryptography techniques to provide authentication and confidentiality of secret data, 2) To design the techniques to protect data secrecy, and 3) To implement and test if the cover media quality is lost after an encrypted message is hidden. The proposed method uses AES encryption to encrypt a message, which is then hidden in video frames using least significant bit steganography. It is implemented using MATLAB with the goal of minimizing quality loss to the cover video.

5. PROBLEM STATEMENT
 Development of large open network makes the security threats increased significantly.For example,modification of
information masquerade and other threats.Therefore, steganography techniques has been apply to secure data during
transmission.However,using only steganography method is no longer secured.Hence,cryptography technique must be
combined together with steganography method to provide better security.
 However ,for the cover media, video file is being used which generally a collection of images and sounds, so most of
the presented techniques on images and audio can be applied to video files too . The great advantages of video are the
large amount of data that can be hidden inside and the fact that it is a moving stream of images and sounds.

6. 1.3 OBJECTIVE
▪ Objective to implement this approach:
▪ 1.To propose a combination of steganography and
cryptography techniques to provide authentication
and confidentiality of that secret data.
▪ 2.To design the proposed techniques to protect the
secrecy of data.
▪ 3.To implement and test if quality of the cover
media is loss after the encrypted message is
hidden into it.

7. 1.4 SCOPES OF PROJECT
▪ a) Project Scope
▪ 1.Security
▪ - Double layer of data hiding
▪ - Message will be encrypted first using aes algorithm and then embedded into
video using lsb techniques.
▪ 2.Minimize Quality Loss
▪ - Quality loss of cover video will be analyzed by using PSNR and MSE

8. ▪ b) User Scope
▪ 1. Sender
▪ - It will make frame extraction
▪ - Then ,sender can choose any file format of video
▪ - Encryption key will be selected.
▪ 2. Receiver
▪ - It will make frame extraction
▪ - It will use secret key for the hidden message decryption.
▪ - Besides that,receiver will enter decryption key to view the secret message
