83 A new steganographic method called STABYLO is introduced in
85 Its main advantage is to be much lighter than the so-called
86 HUGO, WOW, and UNIWARDS schemes, the state of the art
87 steganographic processes.
88 Additionally to this effectiveness,
89 quite comparable results through noise measures like PSNR-HVS-M
90 and weighted PSNR (wPSNR) are obtained.
91 To achieve the proposed goal, famous experimented
92 components of signal processing,
93 coding theory, and cryptography are combined together, leading to
94 a scheme that can reasonably face up-to-date steganalysers.

119 The STABYLO algorithm, whose acronym means STeganography with
120 Adaptive, Bbs, and binarY embedding at LOw cost, has been introduced
121 in this document as an efficient method having comparable, though
122 somewhat smaller, security than well-known
123 steganographic schemes lite
124 HUGO, WOW, and UNIWARD.
125 This edge-based steganographic approach embeds a Canny
126 detection filter, the Blum-Blum-Shub cryptographically secure
127 pseudorandom number generator, together with Syndrome-Trellis Codes
128 for minimizing distortion.
129 After having introduced with details the proposed method,
130 we have evaluated it through noise measures (namely, the PSNR, PSNR-HVS-M,
131 and weighted PSNR), we have used well-established steganalysers.
133 % Of course, other detectors like the fuzzy edge methods
134 % deserve much further attention, which is why we intend
135 % to investigate systematically all of these detectors in our next work.
138 For future work, the authors' intention is to investigate systematically
139 all the existing edge detection methods, to see if the STABYLO evaluation scores can
140 be improved by replacing Canny with another edge filter.
141 Other steganalysers than the ones used in this document will be
142 examined for the sake of completeness. Finally, the
143 systematic replacement of all the LSBs of edges by binary digits provided
144 by the BBS generator will be investigated, and the consequences of such a
145 replacement, in terms of security, will be discussed.
146 Furthermore, we plan to investigate information hiding on other models, such as high frequency for JPEG encoding.
