| Abstract: | A statistical approach was adopted and the effects of hidden information on digital images with the statistical properties were examined. Each image was bit sliced into a set of bit planes. The statistics were calculated on these bit planes and compared between not tampered images and those containing embedded information. As a result, the bit plane correlation density function and the correlation probability distribution chart were defined. A new technique to detect hidden information in space was used by means of bit sliced plane correlation analysis. |

| Keywords: | hidden information correlation density function pixel bit plane peak value bit slicing correlation analysis |
