Abstract:

We propose an algorithm for steganalysis of images based on spread-spectrum data hiding. We employ Markov chains and a combination of threshold method and improved pattern recognition method, and we can discriminate whether an image contains hiding data through detecting the relativity of correlated pixels of the image. Results of the experiments on Corel’s image library show that this algorithm reduces the false alarm rate and increases the precision rate.

Key words: data hiding, spread-spectrum, steganalysis, detection of data hiding
