An Efficeint Hybrid Model for Stegnocrypt Message Transmission

Abstract

Steganography and cryptography is used together to add multiple layers security. Cryptography is a cryptographic technique and which is used to encrypt the visual information. Cryptography is used in data hiding, secure the images, colored image, multimedia and other fields. Steganography is the method of hiding secret data into another data so that it is even more secured. In steganography the secret messages embed in a harmless looking cover such as a digital image file, then the image is transmitted. For encrypt and decrypt the data we can use the cryptography method. The data are converted into some other gibberish form, and then the encrypted data are transmitted. Now a days we have seen a rapid growth of communications security and the antonymous person gain access to secret information for the data communiquéexpert. “Cryptography and Steganography are the widely used techniques to overcome this threat”. LSB method is used to hide the encrypted message into videos. This project is to improve a new method of hiding secret messages into video, the space of representing the characters parallelly we are analysing the video frame using steganalysis.
