Steganography is an art of hiding the secret message in a cover object without leaving a remarkable track on the original message. It is used to increase the security of message sent over the internet. In contrast to cryptography, it is not used to scramble the data but it is used to conceal the data in digital media. This paper will deal with video steganography, cryptography, hash-LSB and an encryption algorithm. At the end, there will be a discussion about the goal of this paper and what types of techniques worked on video steganography.
