39 A novel steganographic method called STABYLO is introduced in this research work.
40 Its main avantage for being is to be much lighter than the so-called
41 Highly Undetectable steGO (HUGO) method, a well known state of the art
42 steganographic process. Additionally to this effectiveness,
43 quite comparable results through noise measures like PSNR-HVS-M,
44 BIQI, and weighted PSNR (wPSNR) are obtained.
45 To achieve the proposed goal, famous experimented components of signal processing,
46 coding theory, and cryptography are combined together, leading to
47 a scheme that can reasonably face up-to-date steganalysers.

70 The STABYLO algorithm, whose acronym means STeganography
71 with cAnny, Bbs, binarY embedding at LOw cost, has been introduced
72 in this document as an efficient method having comparable, though
73 somewhat smaller, security than the well known
74 Highly Undetectable steGO (HUGO) steganographic scheme.
75 This edge-based steganographic approach embeds a Canny
76 detection filter, the Blum-Blum-Shub cryptographically secure
77 pseudorandom number generator, together with Syndrome-Treillis Codes
78 for minimizing distortion.
79 After having introduced with details the proposed method,
80 we have evaluated it through noise measures (namely, the PSNR, PSNR-HVS-M,
81 BIQI, and weighted PSNR) and using well established steganalysers.
83 For future work, the authors' intention is to investigate systematically
84 all the existing edge detection methods, to see if the STABYLO evaluation scores can
85 be improved by replacing Canny with another edge filter. We will try
86 to take into account the least significant bits too during all the
87 stages of the algorithm, hoping by doing so to be closer to the HUGO scores against
88 steganalyzers. Other steganalyzers than the ones used in this document will be
89 examined for the sake of completeness. Finally, the
90 systematic replacement of all the LSBs of edges by binary digits provided
91 by the BBS generator will be investigated, and the consequences of such a
92 replacement, in terms of security, will be discussed.
