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

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