Abstract

Data hiding is a method of hiding secret messages into a cover-media such that an unintended observer will not be\naware of the existence of the hidden messages. We propose new information hiding technique in text, audio, image and video\ndata without embedding any information into the target content by using neural network trained on frequency domain.\nProposed method can detect a hidden bit codes from the content by processing the selected feature sub blocks into the trained\nneural network. Hidden codes are retrieved from the neural network only with the proper extraction key provided. The\nextraction key, in proposed method, are the coordinates of the selected feature sub blocks and the network weights generated\nby supervised learning of neural network. The supervised learning uses the coefficients of the selected feature sub blocks as\nset of input values and the hidden bit patterns are used as teacher signal values of neural network. With our proposed method,\nwe are able to introduce an information hiding scheme with no damage to the target content.
