Blind Multi-Class Steganalysis System Using Wavelet Statistics
Antonio Savoldi, Paolo Gubian · 2007
The aim of this paper is to present an effective multi-class steganalysis system, based on high-order wavelet statistics, capable of attributing stego images to four popular stenographically algorithms, namely F5 [15], Outguess [11], JP Hide&Seek [9], and Steghide [6]. The proposed method, based on a clustering approach, provides significantly reliable results.
