- Abstract
- The article presents a method for detecting steganographic inserts made by the Koh-Zhao method and their locating in gray-scale and color images with low stego-payload (10-25 % of the total carrier). The method is based on two signatures and the subsequent clustering of the existing discrete cosine transform coefficient array and the further selection of the cluster containing the array elements that meet both signature conditions.
