A Novel Approach to Low Volume Generic Steganalysis
Selvaraj Arivazhagan, W. Sylvia Lilly Jebarani, M. Shanmugaraj · 2011
Generic Steganalysis aims to detect the presence of covert communication by identifying the given test data as stego / cover media. Thresholded adjacent pixel differences using different scan paths have been used to highlight feeble embedding artifacts created out of a low rate embedding process. The scan paths normally made use of in the embedding process have been utilized for a steganalytic scheme. A co occurrence matrix derived from thresholded adjacent pixel differences serves as the feature vector aiding detection of stego images carrying very minimal payloads.
