AN APPROACH TO HIDE DATA IN VIDEO USING STEGANOGRAPHY

Deepak Kumar Sharma, AsthaGautam

Abstract: In this paper, we have proposed a new video steganographic algorithm that is used to hide any sort of data or information inside the video with the help of hash function technique. A video steganography is an approach to hide the data inside the video. In general, video is a set of moving frames, so we here are selecting a frame and then applying a hash function technique to choose a pixel for the purpose to hide the information. A double hash function technique is used to select the pixel from row and column. It might happen that the pixel after applying hash function may not found in the frame, this type of problem can occur, so a collision resolution technique is used. A quadratic probing technique is used for solving the problem of collision where we are adding a prime number with the existing hash value instead of linear search. A division method technique is used to point out the pixel in a frame that is pixel’s location in row and column in a frame. When pixel is found, the character of information that is to hide, a binary value of that single character is replaced by original pixel’s red component, then second frame is to select and second character’s binary value is replaced by the original pixel’s green component, this will continue until the all binary characters of the information are hidden.
