Information hiding is a crucial technology in the field of information security. Embedding capacity and stego-image quality are two key performance metrics in information hiding. In recent years, many information-hiding methods have been proposed to enhance embedding capacity and stego-image quality. However, through the study of these methods, we found that there is still room for improvement in terms of performance. This paper proposes a high-capacity information-hiding method based on a chunking matrix (CM). CM divides a 256×256 matrix into blocks, where each block contains k×k corresponding secret numbers. A pair of pixels is extracted from the original image and used as the coordinates for the matrix. In the search domain at that coordinate position, the corresponding secret number is found, and the matrix coordinates of the secret information are used as the pixel value for the stego-image. This paper evaluates the security and effectiveness of CM through measures such as embedding capacity, peak signal-to-noise ratio (PSNR), and bit-plane analysis. CM achieves a maximum embedding capacity of 4.806 bits per pixel (bpp) and maintains a PSNR value of more than 30 dB. Furthermore, the bit-plane analysis fails to detect the presence of the information hidden using CM method. [ABSTRACT FROM AUTHOR]

SHIPBUILDING ,SUSTAINABLE development ,FINANCIAL crises - Abstract
There are ups and downs observed in shipbuilding growth. United Kingdom (UK) was the market leader in global shipbuilding before WWII. After that, Japan became the dominant shipbuilding nation in the 1960s and slowly lost its competitive advantage to the promising industrial nation South Korea, as they had the advantages of much cheaper wages, a suitable shipbuilding strategy, strong government support, and cheaper currency. South Korean shipbuilding overtook Japan's in 2003. In 2009, during and after the global financial crisis China became a global shipbuilding leader leaving behind South Korea and Japan by using the same strategy and technique of the two shipbuilding giants. China utilized the global financial crisis to develop its shipbuilding and they initially targeted the medium and small global market of containers, tankers, and cargo ships. Bangladesh is a maritime nation with a glorious shipping and shipbuilding history. However, the country has failed to keep pace with the global shipbuilding race due to a few reasons. We must utilize our potential and opportunities to meet the challenges for sustainable development of the shipbuilding industry. This analytical paper will describe the potentials and challenges of local shipbuilding in a contest of global and will suggest a suitable shipbuilding market for Bangladesh. [ABSTRACT FROM AUTHOR]

BACKGROUND: Over the past decade, nearly half of internal medicine residencies have implemented block clinic scheduling; however, the effects on residency-related outcomes are unknown. The authors systematically reviewed the impact of block versus traditional ambulatory scheduling on residency-related outcomes, including (1) resident satisfaction, (2) resident-perceived conflict between inpatient and outpatient responsibilities, (3) ambulatory training time, (4) continuity of care, (5) patient satisfaction, and (6) patient health outcomes. METHOD: The authors reviewed the following databases: Ovid MEDLINE, Ovid MEDLINE InProcess, EBSCO CINAHL, EBSCO ERIC, and the Cochrane Library from inception through March 2017 and included studies of residency programs comparing block to traditional scheduling with at least one outcome of interest. Two authors independently extracted data on setting, participants, schedule design, and the outcomes of interest. RESULTS: Of 8139 studies, 11 studies of fair to moderate methodologic quality were included in the final analysis. Overall, block scheduling was associated with marked improvements in resident satisfaction (n = 7 studies, effect size range − 0.3 to + 0.9), resident-perceived conflict between inpatient and outpatient responsibilities (n = 5, effect size range + 0.3 to + 2.6), and available ambulatory training time (n = 5). Larger improvements occurred in programs implementing short (1 week) ambulatory blocks. However, block scheduling may result in worse physician continuity (n = 4). Block scheduling had inconsistent effects on patient continuity (n = 4), satisfaction (n = 3), and health outcomes (n = 3). DISCUSSION: Although block scheduling improves resident satisfaction, conflict between inpatient and outpatient responsibilities, and ambulatory training time, there may be important tradeoffs with worse care continuity.

Key points There are two subtypes of trimeric intracellular cation (TRIC) channels but their distinct single‐channel properties and physiological regulation have not been characterized. We examined the differences in function between native skeletal muscle sarcoplasmic reticulum (SR) K+‐channels from wild‐type (WT) mice (where TRIC‐A is the principal subtype) and from Tric‐a knockout (KO) mice that only express TRIC‐B.We find that lone SR K+‐channels from Tric‐a KO mice have a lower open probability and gate more frequently in subconducting states than channels from WT mice but, unlike channels from WT mice, multiple channels gate with high open probability with a more than six‐fold increase in activity when four channels are present in the bilayer.No evidence was found for a direct gating interaction between ryanodine receptor and SR K+‐channels in Tric‐a KO SR, suggesting that TRIC‐B–TRIC‐B interactions are highly specific and may be important for meeting counterion requirements during excitation–contraction coupling in tissues where TRIC‐A is sparse or absent. Abstract The trimeric intracellular cation channels, TRIC‐A and TRIC‐B, represent two subtypes of sarcoplasmic reticulum (SR) K+‐channel but their individual functional roles are unknown. We therefore compared the biophysical properties of SR K+‐channels derived from the skeletal muscle of wild‐type (WT) or Tric‐a knockout (KO) mice. Because TRIC‐A is the major TRIC‐subtype in skeletal muscle, WT SR will predominantly contain TRIC‐A channels, whereas Tric‐a KO SR will only contain TRIC‐B channels. When lone SR K+‐channels were incorporated into bilayers, the open probability (Po) of channels from Tric‐a KO mice was markedly lower than that of channels from WT mice; gating was characterized by shorter opening bursts and more frequent brief subconductance openings. However, unlike channels from WT mice, the Po of SR K+‐channels from Tric‐a KO mice increased as increasing channel numbers were present in the bilayer, driving the channels into long sojourns in the fully open state. When co‐incorporated into bilayers, ryanodine receptor channels did not directly affect the gating of SR K+‐channels, nor did the presence or absence of SR K+‐channels influence ryanodine receptor activity. We suggest that because of high expression levels in striated muscle, TRIC‐A produces most of the counterion flux required during excitation‐contraction coupling. TRIC‐B, in contrast, is sparsely expressed in most cells and, although lone TRIC‐B channels exhibit low Po, the high Po levels reached by multiple TRIC‐B channels may provide a compensatory mechanism to rapidly restore K+ gradients and charge differences across the SR of tissues containing few TRIC‐A channels., Key points There are two subtypes of trimeric intracellular cation (TRIC) channels but their distinct single‐channel properties and physiological regulation have not been characterized.

BLOCKS (Group theory) ,LOGICAL prediction ,FINITE simple groups - Abstract
In this paper, we focus on Brauer's height zero conjecture, Robinson's conjecture, and Olsson's conjecture regarding the direct product of finite groups and give relative versions of these conjectures by restricting them to the algebraic concept of the anchor group of an irreducible character. Consider G to be a finite simple group. We prove that the anchor group of the irreducible character of G with degree p is the trivial group, where p is an odd prime. Additionally, we introduce the relative version of the Green correspondence theorem with respect to this group. We then apply the relative versions of these conjectures to suitable examples of simple groups. Classical and standard theories on the direct product of finite groups, block theory, and character theory are used to achieve these results. [ABSTRACT FROM AUTHOR]

We consider G to be a finite group and p as a prime number. We fix ψ to be an irreducible character of G with its restriction to all p-regular elements of G and ψ 0 to be an irreducible Brauer character. The main aim of this paper is to describe and investigate the relationship between cyclic anchor group of ψ and the defect group of a p-block which contains ψ. Our methods are to study and generalize some facts for the cyclic defect groups of a p-block B to the case of a cyclic anchor group of irreducible characters which belong to B. We establish and prove a criteria for an irreducible character to have a cyclic anchor group. [ABSTRACT FROM AUTHOR]

BLOCK codes - Abstract
In this paper, we introduce codes equipped with pomset block metric. A Singleton type bound for pomset block codes is obtained. Code achieving the Singleton bound, called a maximum distance separable code (for short, MDS ( P , π )-code) is also investigated. We extend the concept of I-perfect codes and r-perfect codes to pomset block metric. The relation between I-perfect codes and MDS (P , π) -codes is also considered. When all blocks have the same dimension, we prove the duality theorem for codes and study the weight distribution of MDS pomset block codes when the pomset is a chain. [ABSTRACT FROM AUTHOR]

SOCIAL media ,SOCIABILITY ,SOCIAL media in business - Abstract
Online spaces provide opportunities for creating ties with other people, allowing us to communicate and share content with them. Sometimes, though, we wish to break some of these ties; we wish not only to friend and to follow, but to unfriend and unfollow as well. In this paper, we present a history of the many features for online interpersonal disconnectivity, showing how they have developed over time. We present five main findings: the language of tie breaking is consistently bureaucratic; over time, the features for tie breaking tend to operate on the feed rather than on social ties themselves; platforms are more reactive than proactive when it comes to tie breaking features; new ways for preventing interactions are launched over time; and the features for tie breaking sometimes create what we call "impossible social situations." This approach shines a spotlight on a neglected aspect of social media, and opens up new ways of thinking about how the platforms conceive of–and construct–online sociability. [ABSTRACT FROM AUTHOR]

Outstanding skills, including special isolated skills (SIS) and perceptual peaks (PP) are frequent features of autism. However, their reported prevalence varies between studies and their co-occurrence is unknown. We determined the prevalence of SIS in a large group of 254 autistic individuals and searched for PP in 46 of these autistic individuals and 46 intelligence and age-matched typically developing controls. The prevalence of SIS among autistic individuals was 62.5 % and that of PP was 58 % (13 % in controls). The prevalence of SIS increased with intelligence and age. The existence of an SIS in a particular modality was not associated with the presence of a PP in the same modality. This suggests that talents involve an experience-dependent component in addition to genetically defined alterations of perceptual encoding.

A complex unit gain graph, or T -gain graph, is a triple Φ = (G , T , φ) comprised of a simple graph G as the underlying graph of Φ, the set of unit complex numbers T = { z ∈ C : | z | = 1 } , and a gain function φ : E → → T with the property that φ (e i j) = φ (e j i) − 1. A cactus graph is a connected graph in which any two cycles have at most one vertex in common. In this paper, we firstly show that there does not exist a complex unit gain graph with nullity n (G) − 2 m (G) + 2 c (G) − 1 , where n (G) , m (G) and c (G) are the order, matching number, and cyclomatic number of G. Next, we provide a lower bound on the nullity for connected complex unit gain graphs and an upper bound on the nullity for complex unit gain bipartite graphs. Finally, we characterize all non-singular complex unit gain bipartite cactus graphs, which generalizes a result in Wong et al. (2022) [30]. [ABSTRACT FROM AUTHOR]

- Abstract
As the feature size of integrated circuit decreases, semiconductor devices become more susceptible to Single-Event-Upset (SEU) effect. This paper proposes a radiation hardened latch for Triple-Node-Upset (TNU) tolerance, which can block any triple node upset. Compared with previous radiation hardened TNU Tolerant (TNUT) latches, the proposed Low power-consumption TNUT (LTNUT) latch has the lowest power consumption. When compared with TNU Hardened Latch (TNUHL), TNUT Latch, TNU Completely Tolerant latch (TNUCT), Single-event Multiple-Node Upset Tolerant latch (SMNUT), TNU self-Recoverable Latch (TNURL), Low Cost and TNU-self-Recoverable Latch (LCTNURL) and Quadruple Dual Interlocked Storage Cell (Quadruple-DICE), the proposed LTNUT latch achieves reduction in power consumption by 30.77%, 17.11%, 40%, 20.25%, 20.25%, 27.59% and 64%, respectively. The proposed LTNUT latch achieves reduction in delay by 94.98%, 98.33%, 54.19%, 70.63% and 66.59% when compared with TNUHL, TNUT Latch, SMNUT, TNURL, LCTNURL, respectively, and introduces rise in delay by 3.38% and 5.52%, respectively, when compared with TNUCT and Quadruple-DICE. The proposed LTNUT latch has the lowest power consumption and second smallest delay. The proposed latch is not severely sensitive to temperature and voltage variations. [ABSTRACT FROM AUTHOR]

Objective To assess the postoperative outcome between pudendal nerve block and caudal block after open lateral internal sphincterotomy for chronic anal fissure. Methods Our prospective, randomized and double blind investigation included 123 patients, of both sexes, aged 25-56 years, classed I-II by the American society of anesthesiologists and scheduled for elective open internal lateral sphincterotomy for anal fissure at King Hussein hospital, KHMC, Amman, Jordan, during the period from Jan. 2013 to Feb. 2015. Patients were divided into two groups. Group I included 62 patients (GI, n=62) operated under pudendal nerve block with local infiltration anesthesia and group II included 61 patients (GII, n=61) operated under caudal block. Postoperative pain, surgical duration, period of hospital admission, back to regular working activity and 4 weeks evaluation were compared between the two groups. Results Postoperative outcome was more enhanced in group II but not significant than in group I. Patients in G-I experienced moderate pain for a mean of 5. 3 days in comparison with 4. 3 days in G-II. P>0. 05. Three patients (4. 9%) in G-II in comparison with 5 patients (8. 1%) in G-I had more hospital stay than 24 hours. Patients in G-II went back to normal activity after a mean of 7. 5 days in comparison with 8. 0 days in G-I. Conclusion Undergoing open lateral internal sphincterotomy with the aid of Pudendal nerve block is an excellent, easy and safe alternative anesthesia to caudal anesthesia.

Congenitally corrected transposition of the great arteries (ccTGA) is a rare congenital anomaly defined by double discordance – atrioventricular and ventricular-arterial. ccTGA frequently has associated lesions, which influence long-term survival. The management of patients with ccTGA regarding the closure of defects and pacing strategies is often very challenging. Moreover, tricuspid valve regurgitation and its impact on the systemic right ventricle requires close monitoring and potentially timely interventions. In this paper, we present and discuss the management challenges raised by a patient with situs inversus totalis, dextrocardia, ccTGA, Ebstein anomaly of the tricuspid valve, atrial septal defect, and complete atrioventricular block.

This paper mainly contributes a bit-level and pixel-level double-permutation image encryption scheme based on DNA coding technology, which can effectively solve the problem that adjacent pixels in an image are difficult to be completely disordered. Firstly, the Hamming distance between image pixel and a value at the same position in a chaotic sequence is calculated and the result is used to be the cyclic shift distance of the pixel to achieve bit-level permutation; secondly, the modified Z curve is used for the first global permutation process, and the image is further permutated by the method of block restructuring to compensate for the shortage of modified Z curve permutation; thirdly, pixel pairs are selected and the pixel pairs are used as information and control positions respectively to DNA encode the image by dynamically selecting the DNA encoding rules, and then diffusing the encoded image following the rules of DNA base manipulation; finally, the diffused image is decoded to complete the image encryption process. We perform simulation experiments on the image encryption algorithm and analyze its security performance, and we could get the conclusion that the encryption algorithm can encrypt images quickly and effectively, the obtained cipher images are highly resistant to noise attacks, cropping attacks, and different attacks, meanwhile, the cipher images have a lower correlation between pixels.

Let G = (V (G), E(G)) be a simple undirected graph. A block of G is a maximal connected subgraph of G that contains no cut-vertices [11]. The family of vertex sets of blocks of G generates a unique topology. In this paper, we formally define the topology generated by the family of blocks in a graph called the block topological space. Moreover, we characterize and describe some special attributes of the block topological space. Finally, we associate a corresponding graph from a given block topological space by defining the block topological graph. [ABSTRACT FROM AUTHOR]

Let G be a vertex-colored graph. A vertex cut S of G is called a monochromatic vertex cut if the vertices of S are colored with the same color. A graph G is monochromatically vertex-disconnected if any two nonadjacent vertices of G have a monochromatic vertex cut separating them. The monochromatic vertex disconnection number of G , denoted by m v d (G) , is the maximum number of colors that are used to make G monochromatically vertex-disconnected. In this paper, the connection between the graph parameters are studied: m v d (G) , connectivity and block decomposition. We determine the value of m v d (G) for some well-known graphs, and then characterize G when n − 5 ≤ m v d (G) ≤ n and all blocks of G are minimally 2-connected triangle-free graphs. We obtain the maximum size of a graph G with m v d (G) = k for any k. Finally, we study the Erdős-Gallai-type results for m v d (G) , and completely solve them. [ABSTRACT FROM AUTHOR]

In this paper we follow a hypothetical mathematician who is working on a problem that is eventually solved. We treat this problem as if it were difficult for the mathematician. In following the mathematician's work, we note both what she does and what she doesn't do in the process. By the latter, we consider the times when progress is not being made and how this lack of progress is resolved. The purpose here is to give some idea of how a research mathematician might approach a research level problem. We also propose that the problem under discussion is one of many problems that tertiary students can valuably tackle using a discovery-based approach as a means of using their mathematical content knowledge as well as learning to be creative.

The main argument of this paper is that variation in state level institutions and local government administrative capacity are key factors in explaining the distribution of non-entitlement Community Development Block Grants (CDBG) in states. More specifically, we argue that local government capacity is positively associated with access to non-entitlement CDBGs, and decentralized state-level allocation institutions enhance access to these intergovernmental block grants as well. This paper provides a comparative institutional analysis of the allocation of non-entitlement Community Development Block Grants across four states: Texas, California, Kentucky, and Utah. We use probit, Poisson, and Tobit models to determine whether access to non-entitlement CDBGs is a function of variance in local government capacity and state-level institutional variation. We find that from 1999-2001, state institutions influence the odds of receiving a grant and the number of grants, but not the funding levels in dollars. These findings raise important questions about whether state administration of the non-entitlement CDBG program prevents local governments most in need of federal assistance from receiving federal assistance.

37. HFAC Dose Repetition and Accumulation Leads to Progressively Longer Block Carryover Effect in Rat Sciatic Nerve.

- Abstract
This paper describes high-frequency nerve block experiments carried out on rat sciatic nerves to measure the speed of recovery of A fibres from block carryover. Block carryover is the process by which nerve excitability remains suppressed temporarily after High Frequency Alternative (HFAC) block is turned off following its application. In this series of experiments 5 rat sciatic nerves were extracted and prepared for ex-vivo stimulation and recording in a specially designed perfusion chamber. For each nerve repeated HFAC block and concurrent stimulation trials were carried out to observe block carryover after signal shutoff. The nerve was allowed to recover fully between each trial. Time to recovery from block was measured by monitoring for when relative nerve activity returned to within 90% of baseline levels measured at the start of each trial. HFAC block carryover duration was found to be dependent on accumulated dose by statistical test for two different HFAC durations. The carryover property of HFAC block on A fibres could enable selective stimulation of autonomic nerve fibres such as C fibres for the duration of carryover. Block carryover is particularly relevant to potential chronic clinical applications of block as it reduces power requirements for stimulation to provide the blocking effect. This work characterizes this process toward the creation of a model describing its behavior. [ABSTRACT FROM AUTHOR]

Flexible surface treatment for exterior pavement applications and the particular requirement to be specific pedestrian walkway design and parking areas are the fundamental feature of paver block identification. The use of conventional materials such as cement, aggregate, and sand is no longer such a priority. Under those circumstances, the production of research-based pavers block has been done to ensure the sustainability and usability of new building materials is expanded. Henceforth, this research is conducted to study and investigate the potential of using waste materials as a partial substitute for aggregate in producing concrete paving block (CPB). In essence, the application of waste materials in concrete paver blocks is highly potential. The innovations in recycling technologies expanded the usage of waste materials to produce paver block products. On the whole, in the manufacturing of concrete, the paper improves and enhances the usability of waste materials. The application of various waste materials such as plastic, steel slag, and crumb rubber is excellent. Compressive strength of paver blocks with different rates of waste steel aggregates and utilizing elastic cushions shows paver blocks give up to 50% more strength quality than customary paver blocks. In terms of the use of industrial waste materials, as a substitute material by reducing the percentage amount of the weight of the cement with the composition ratio varies based on the comparative volume category of the paving block aggregate such as 0%, 5%, 10%, 15%, 20%, and 25% are more applicable.

- Abstract
The paper introduces the horizontal crustal movement obtained from GPS observations in the regional networks (including the basic network and the fiducial network) of the Crustal Movement Observation Network of China (CMONOC) carried out in 1999 and 2001. This paper is characterized by the acquisition of the horizontal displacement velocities during the period from 1999 to 2001 at the observation stations in the regional networks with datum definition of a group of stable stations with small mutual displacements in east China. Based on the most detailed map of horizontal crustal movement in Chinese mainland, the division of blocks, their displacements and deformations are studied. An approach to analysis of the intensity of the horizontal crustal deformation is proposed. The general characteristics of the recent horizontal crustal movement in Chinese mainland and that before the Kunlunshan earthquake of M=8.1 on November 14, 2001 are analyzed. [ABSTRACT FROM AUTHOR]

The concept of a tolerance relation, shortly called tolerance, was studied on various algebras since the seventies of the twentieth century by B. Zelinka and the first author (see e.g. [6] and the monograph [1] and the references therein). Since tolerances need not be transitive, their blocks may overlap and hence in general the set of all blocks of a tolerance cannot be converted into a quotient algebra in the same way as in the case of congruences. However, G. Czédli ([7]) showed that lattices can be factorized by means of tolerances in a natural way, and J. Grygiel and S. Radeleczki ([8]) proved some variant of an Isomorphism Theorem for tolerances on lattices. The aim of the present paper is to extend the concept of a tolerance on a lattice to posets in such a way that results similar to those obtained for tolerances on lattices can be derived.

An adaptive force model is proposed to achieve better performance between the accuracy and the speed of cloth simulation in three-dimensional (3D) space. The proposed force model can be expressed with a general mathematical form demonstrated by the distance between the clothing and the human body. This paper defines how a continuous adaptive area can be established with a shape "block". It is clarified that, within a specific block, a force model is expressed with the gravity of the clothing, the forces of the adjacent blocks and the anti-force of the human body to the block. In this manner, the force model of the desired clothing can be obtained through a general mathematical expression. The simulations and experimental results demonstrate that the acceptable clothing simulation in 3D space can be achieved with higher speed by saving about 20.2% runtime, and the efficiency of the proposed scheme can be verified.

- Abstract
Compressed sensing (CS) is a novel theory for simultaneous data sampling and compression. The block compressed sensing can reduce the computation complexity and storage space for compressed sensing. In this paper, the weight-block compressed sensing technique coupled with the edge information is presented for improving the reconstructed image quality. Firstly, we segment the original image into block by block. Based on the edge characteristic of every sub-block, we will select the different measurements that needed for each block. This algorithm can preserve the edge and reduce the aliasing in comparison to the traditional block-compressed sensing. Experimental results show that the proposed algorithm can improve the PSNR comparing with the usual method. [ABSTRACT FROM PUBLISHER]

Peter Cameron introduced the concept of the circular altitude of graphs, a parameter which was shown by Bamberg et al. that provides a lower bound on the circular chromatic number. In this paper, we investigate this parameter and show that the circular altitude of a graph is equal to the maximum of circular altitudes of its blocks. Also, we show that homomorphically equivalent graphs have the same circular altitudes. Finally, we prove that the circular altitude of the Cartesian product of two graphs is equal to the maximum of circular altitudes of its factors. [ABSTRACT FROM AUTHOR]

This paper addresses the issue of selecting an appropriately sized unit of analysis for the measurement of the concepts involved in social disorganization theory and routine activity theory. With the use of Hierarchical Linear Methodology and the introduction of both intra- and inter-level interaction terms, this paper examines the role of relatively micro-level units versus relatively macro-level units in the prediction of the spatial distribution of three types of street crime. On the theoretical front, this examination addresses the general debate as to the role of ?awareness space? versus the role of an emergent milieu of a larger social context. On the methodological front, it addresses the issue that large units are suspected of introducing error through within unit heterogeneity, while small units are suspected of heightening autocorrelational errors. Both micro- and macro-level social contexts are found to be important to understanding the ecology of street crime, and the influence of micro-level characteristics are found to be contingent on the macro-level environments in which they are nested.

Summary: Past earthquakes had shown vulnerability of infill walls especially under out of plane (OOP) loading. Although some new infill walls show a good OOP performance, generally, they do not have the right economic justification or have complexity in construction. Therefore, in this paper, an innovative economical infill wall is presented that is not complicated in construction. The proposed wall constructed by light expanded clay aggregate in especial shape that reinforced with side plates, top, and bottom rebars. Experimental and numerical studies were carried out to investigate its seismic performance. Experimental results showed a high continuity between blocks of wall due to its especial shape that is increased ultimate OOP strength and ultimate OOP displacement of the wall. Numerical results indicated, because the infill wall is isolated from boundary frame, no drift is imposed to infill wall from boundary frame. Therefore, the infill wall only suffered OOP seismic acceleration. Due to light weight of the infill wall, low OOP load that corresponds to seismic acceleration is applied to the infill wall. In the infill wall, no separation is made even up to drift frame of 2.5%. The relations to design of the proposed infill wall were also presented. [ABSTRACT FROM AUTHOR]

Smartphone sensors are widely used in the development of fitness, running, workout, or health applications (apps). However, smartphone sensors may increase the risk of privacy leakage when they bring convenience to users. Traditional access control mechanisms, such as Android Permission, cannot prevent authorized malicious apps from abusing sensor resources. In this paper, a novel behavior-based sensor access control scheme is presented. This scheme can further regulate the behavior of an app after it is authorized, so that it can only access sensor resources with secure behavior patterns (SBPs), and sensor-based privacy leakage may thereby be blocked. On the basis of user interface (UI) operation tracking and tagging, this scheme implements the dynamic perception of app sensor access behaviors. With a temporal logic known as temporal logic of causal knowledge (TLCK), we developed a method to construct the secure sensor access behavior pattern. Every sensor may be given a SBP. By comparing the dynamic sensor access behavior of an app with SBP, we can determine if the sensor access is secure. Moreover, by supervising the call stack of the app's sensor access application programming interface (API), we may timely block a sensor access when it is not secure. In this report, we also describe the implementation of a prototype defense system to analyze the effectiveness and efficiency of the scheme. The experimental results show that this scheme can effectively block the abnormal sensor access of an app with a performance overhead of about 10%. [ABSTRACT FROM AUTHOR]
