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

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