摘要：Information Security is viewed as an important field of research over the last few years. Individual’s confidential data or company’s trade secrets are very sensitive data. To date, many cryptographic techniques are implemented to make meaningless sense of the secret information. If an unauthorized person gets hold of the encryption key, he can easily decrypt the meaning of secret information. This paper discusses another method of securing the secret information known as steganography, where the presence of the information is hidden. In this paper, a video steganographic model is proposed which imposes the concept of secrecy over privacy for text messages in video. In this model, text data is hidden inside a video file of .avi format. The technique used to steganograph the text data in video is the Least Significant Bit (LSB) insertion method. The goal of this paper is to keep the presence of the message secret, or hide the fact that communication is taking place. The model proposed also allows us to hide large amount of secret data in video.
