Abstract:This work explores the extent to which LSB embedding can be made secure against structural steganalysis through a modification of cover image statistics prior to message embedding. Natural images possess symmetries that are expressed through approximately equal cardinalities of certain sets of ktuples of consecutive pixels. LSB embedding disturbs this balance and a k th -order structural attack infers the presence of a hidden message with a length in proportion to the size of the imbalance amongst sets of k-tu… Show more
