ABSTRACT
Nowadays, the growth of high speed computer networks and that of the Internet in particular has increased the ease of Information Communication. Besides that, the cause for the development is also of the apprehension which is the use of digital formatted data. In comparison with analog media, digital media offers several distinct advantages such as high quality, easy editing and compression. Analog media is like printed paper, recorded sound, magazines and videotapes film which is in original form whereas digital media is whether created from scratch on computers or converted from analog media sources are composed of digital codes. But this type advancement in the field of data communication in other sense has hiked the fear of getting the data snooped at the time of sending it from the sender to the receiver. So, Information Security is becoming an inseparable part of Data Communication. In order to address this Information Security, Steganography plays an important role. Steganography is the art and science of writing hidden messages in such a way that no one apart from the sender and intended recipient even realizes there is a hidden message. In the current internet community, secure data transfer is limited due to its attack made on data communication. So more robust methods are chosen so that they ensure secured data transfer. One of the solutions which came to the rescue is the video steganography. In this paper, we propose a combination of cryptography and steganography as solution. For cryptography, we are using RSA algorithm to make an encryption whereas in video steganography (Least Significant Bit) LSB insertion method is used. In this project, the message will be encrypted first before embedded it into video steganography. MATLAB software will be used as a tool during this project implementation. The result will be analysed with different term which are Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE).As a conclusion, this proposed approach will improves data security during communication and significantly prevent eavesdrop from happened.
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.
OBJECTIVES
▪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.
FRAMEWORK
1. First, the sender should encrypt the message using RSA algorithm.
2.Then, the user have to embed the secret message into the cover video using LSB algorithm. 3.Stego-Video will formed. 4.Next,the receiver have to extract the secret message from its video using LSB algorithm. 5.Receiver then should decrypt the message. 6.Original message will be retrieved. |
RESULTS
CONCLUSION
Video Steganography is used for the secure transmission of data which is hidden in the video. The parameters are used to check the quality of the stego video are MSE and PSNR. The experimental results show high PSNR and low MSE is for good quality of stego video but not for secure transmission. For the secure transmission, RSA algorithm is implement before the data is embedded into the video.
