96 \abstracttext{A novel steganographic method called STABYLO is introduced in
98 Its main avantage for being is to be much lighter than the so-called
99 Highly Undetectable steGO (HUGO) method, a well known state of the art
100 steganographic process in spatial domain.
101 Additionally to this effectiveness,
102 quite comparable results through noise measures like PSNR-HVS-M,
103 BIQI, and weighted PSNR (wPSNR) are obtained.
104 To achieve the proposed goal, famous experimented
105 components of signal processing,
106 coding theory, and cryptography are combined together, leading to
107 a scheme that can reasonably face up-to-date steganalysers.}

129 The STABYLO algorithm, whose acronym means STeganography
130 with cAnny, Bbs, binarY embedding at LOw cost, has been introduced
131 in this document as an efficient method having comparable, though
132 somewhat smaller, security than the well known
133 Highly Undetectable steGO (HUGO) steganographic scheme.
134 This edge-based steganographic approach embeds a Canny
135 detection filter, the Blum-Blum-Shub cryptographically secure
136 pseudorandom number generator, together with Syndrome-Treillis Codes
137 for minimizing distortion.
138 After having introduced with details the proposed method,
139 we have evaluated it through noise measures (namely, the PSNR, PSNR-HVS-M,
140 BIQI, and weighted PSNR) and using well established steganalysers.
142 For future work, the authors' intention is to investigate systematically
143 all the existing edge detection methods, to see if the STABYLO evaluation scores can
144 be improved by replacing Canny with another edge filter. We will try
145 to take into account the least significant bits too during all the
146 stages of the algorithm, hoping by doing so to be closer to the HUGO scores against
147 steganalyzers. Other steganalyzers than the ones used in this document will be
148 examined for the sake of completeness. Finally, the
149 systematic replacement of all the LSBs of edges by binary digits provided
150 by the BBS generator will be investigated, and the consequences of such a
151 replacement, in terms of security, will be discussed.
