“…Un ejemplo puede ser el diseño de sistemas que mediante el uso del lenguaje natural permiten crear sistemas de memorización de claves de acceso (password) más seguros, claves más difíciles de deducir por un atacante pero fáciles de memorizar para el usuario legítimo (Atallah, McDonough, Raskin y Nirenburg, 2000).…”

RESUMEN:La lingüística computacional puede ser aprovechada junto a la ciencia de la esteganografía lingüística para diseñar sistemas útiles en la protección/privacidad de las comunicaciones digitales y en el marcado digital de textos. No obstante, para poder llevar a cabo tal tarea se requiere de una serie de condiciones que no siempre se dan. En este artículo se investiga si es posible diseñar procedimientos que permitan ocultar información en lenguaje natural utilizando la mínima cantidad de recursos tanto lingüísticos como computacionales. Se propone un algoritmo y se implementa, razonando posteriormente a favor de la utilidad y la seguridad de propuestas de este tipo.PALABRAS CLAVE: Esteganografía lingüística; marcado digital; NLW; algoritmo. ABSTRACT:Computational linguistics and linguistic steganography could allow to design useful systems in the protection / privacy of digital communications and digital language watermarking. However, building these systems is not always possible provided a series of conditions are not met. This article investigates whether it is possible to design procedures to hide information in natural language using minimal linguistic and computational resources. An algorithm is proposed and implemented, arguing for the usefulness and security of such proposals.

In this paper we discuss natural language watermarking, which uses the structure of the sentence constituents in natural language text in order to insert a watermark. This approach is different from techniques, collectively referred to as "text watermarking," which embed information by modifying the appearance of text elements, such as lines, words, or characters. We provide a survey of the current state of the art in natural language watermarking and introduce terminology, techniques, and tools for text processing. We also examine the parallels and differences of the two watermarking domains and outline how techniques from the image watermarking domain may be applicable to the natural language watermarking domain.

“…The format-based methods always hide message by character spaces assignment, line shifting and word shifting [1], changing font format in compound documents or some sole characteristics in specific documents [2]. Linguistic steganography referred to natural language steganogra- phy [3], mainly uses mimicking techniques to directly generate a new cover text [4], or linguistically modifies content of cover text by synonym substitution (SS) [5]- [11], syntactic transformation [12], [13], or translation [14], [15] to camouflage the secret message. Synonym substitution is the major and famous transformation used in linguistic steganography.…”

SUMMARY In order to prevent the synonym substitution breaking the balance among frequencies of synonyms and improve the statistical undetectability, this paper proposed a novel linguistic steganography based on synonym run-length encoding. Firstly, taking the relative word frequency into account, the synonyms appeared in the text are digitized into binary values and expressed in the form of runs. Then, message are embedded into the parities of runs' lengths by self-adaptively making a positive or negative synonym transformation on boundary elements of two adjacent runs, while preserving the number of relative high and low frequency synonyms to reduce the embedding distortion. Experimental results have shown that the proposed synonym run-length encoding based linguistic steganographic algorithm makes fewer changes on the statistical characteristics of cover texts than other algorithms, and enhances the capability of anti-steganalysis.
