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

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