Abstract
We propose a digital information hiding technique in which we use a combination of a random sequence and the Hadamard matrix to hide multiple information in a digital image. Earlier work used only one random sequence multiplied by an information signal to spread the spectrum of the information signal, making it difficult for a third party to detect the information signal or jam it. But in the case of hiding multiple information in the same digital image, the use of only different random sequences that are generally not orthogonal to each other has some problems because of the cross-correlation between the sequences. Thus we present a new information hiding scheme that can be used to hide multiple information using both a random sequence that spreads the energy level of the data to be hidden and a Hadamard matrix, which results in the random sequence being uncorrelated.
