This research was based on the study conducted by Khodaei et al. (2012), namely, the least significant-bit (LSB) substitution combined with the pixel-value differencing (PVD) steganography, and presented an improved irreversible image steganography method. Such a method was developed through integrating the improved LSB substitution with the modulus function-based PVD steganography to increase steganographic capacity of the original technique while maintaining the quality of images. It partitions the cover image into non overlapped blocks, each of which consists of 3 consecutive pixels. The 2nd pixel represents the base, in which secret data are embedded by using the 3-bit LSB substitution. Each of the other 2 pixels is paired with the base respectively for embedding secret data by using an improved modulus PVD method. The experiment results showed that the method can greatly increase steganographic capacity in comparison with other PVD-based techniques (by a maximum amount of 135%), on the premise that the quality of images is maintained. Last but not least, 2 security analyses, the pixel difference histogram (PDH) and the content selective residual (CSR) steganalysis were performed. The results indicated that the method is capable of preventing the detection of the 2 common techniques.

In this article, we introduce new sequence spaces U(T(x), F, p, u), U(Tw(x), F, p, u) and U(Tw*(h), F, p, u) by using Fibonacci matrix and sequence of modulus func-tions. We make an effort to study some characterizations of weakly unconditionally Cauchy series associated to newly formed sequence spaces. Finally, the barreledness of a normed space Y is characterized by means of weakly* unconditionally Cauchy series in Y*.

This letter improves two adaptive steganographic methods in Refs. [5], [6], which utilize the remainders of two consecutive pixels to record the information of secret data. Through analysis, we point out that they perform mistakenly under some conditions, and the recipient cannot extract the secret data exactly. We correct these by enlarging the adjusting range of the remainders of two consecutive pixels within the block in the embedding procedure. Furthermore, the readjusting phase in Ref. [6] is improved by allowing every two-pixel block to be fully modified, and then the sender can select the best choice that introduces the smallest embedding distortion. Experimental results show that the improved method not only extracts secret data exactly but also reduces the embedding distortion.

In this study we first established the relations between f-density and g-density of a subset of the set of positive integers for any modulus functions f and g. Using the obtained facts we establish the relationship between the sets S-f and S-g of statistically convergent and BSf and BSg of statistically bounded sequences which defined by modulus functions f and g.

In this paper, we defined space S theta alpha,beta(Delta vm,E,q) of all vector-valued lacunary Delta vm-statistical convergent sequences of order (alpha,beta) and space N theta alpha,beta(Delta vm,E,q,p) of all vector-valued strongly Delta vm-lacunary summable sequences of order (alpha,beta) by taking sequence (Ek,qk) of normed spaces, where p is a positive real number and alpha,beta are real numbers with 0<beta 1. Some inclusion relations between these spaces are obtained. We also studied space omega theta alpha,beta(Delta vm,f,E,q,p) of all vector-valued strongly Delta vm-lacunary summable sequences of order (alpha,beta) with respect to modulus function f by taking a bounded sequence (pk) of strictly positive real numbers with infkpk>0. The inclusion relations between spaces omega theta alpha,beta(Delta vm,f,E,q,p) and S theta alpha,beta(Delta vm,E,q) are determined.

In this paper we extend the idea of weighted density of Balcerzak et al. (2015) by using a modulus function and introduce the idea f -density of weight g of subsets of omega := {0,1, ...} (at the same time extending the notion of f-density (Aizpuru et al., 2014)), which we name d(g)(f) where g : omega -> [0, infinity) satisfies g(n) -> infinity and n/g(n) -> 0 and f is a modulus function. The aim of this paper is to show that we can get new ideals Z(g)(f) consisting of sets A subset of omega co for which d(g)(f) (A) = 0 different from all the previously constructed ideals Z(g) (f) of Balcerzak et al. (2015) and moreover they retain all the nice properties of the ideals Z(g). (C) 2018 Royal Dutch Mathematical Society (KWG). Published by Elsevier B.V. All rights reserved.
