Data Hiding by using Neural Network in Video file

-Information Hiding is a method of hiding secret messages into a cover-media such that an intended observer will not be aware of the existence of hidden messages. In such applications various file formats are used as cover-object which contains confidential data. Steganography provide security and make safe the data of very important significance. Video Steganography is the technique of hiding some covert message inside a video. The addition of this information to the video is not recognizable through the human eye as modify of a pixel colour is negligible. This urges the researcher’s to devise new data hiding techniques through Steganography principle is to secure the data of very important significance. This paper we focus simple review Steganography methods. Keywords-Steganography, Data hiding, NN (Neural Network).
