Steganography is an art of hiding information into something that looks something else (legitimate) but in fact contains the message embedded into it. This technique is very old and have been used during the wars in order to communicate secret messages and codes within the battalions, brigades and teams. In this writeup we are going to see the same technique and will be analyzing different. The idea behind steganography is embedding plaintext messages in places where an unsuspecting user would not think them to be present. During steganalysis, our objective is to discover where and how these plaintext messages are hidden within the provided files or data. Steganalysis is a process of trial-and-error

However, the cost of storing large files in the blockchain is too high. To solve the above problems, we propose a double steganography model which combines blockchain and interplanetary file system (IPFS) in this paper. The model consists of two parts: image steganography and plain text steganography The word steganography has Greek origins and means 'concealed writing.' The original practice can be traced back to around 440 BC when the ancient Greeks hid messages within wax tablets by writing messages on the wood before applying a wax surface (Herodotus 1987).Another early recorded use of steganography occurred in ancient Greece when messengers tattooed messages on their shaved heads. It is naturally regarded that high-capacity image steganography model can be readily used to solve the video steganography prob-lem, by pairing frames in cover / secret videos and feeding them into an image model. We argue that this tactic is not optimal, be-cause it does not fully consider the temporal redundancy within consecutive video frames Least Significant Bit Steganography. We can describe a digital image as a finite set of digital values, called pixels. Pixels are the smallest individual element of an image, holding values that represent the brightness of a given color at any specific point. So we can think of an image as a matrix (or a two-dimensional array) of pixels which.
