关键词： privacy security   mobile payment app   financial transaction action   traffic identification  

摘要： Mobile payment apps have been widely-adopted, which brings great convenience to people's lives. However, at the same time, user's privacy is possibly eavesdropped and maliciously exploited by attackers. In this paper, we consider a possible way for an attacker to monitor people's privacy on a mobile payment app, where the attacker aims to identify the user's financial transactions at the trading stage via analyzing the encrypted network traffic. To achieve this goal, a hierarchical identification system is established, which can acquire users' privacy information in three different manners. First, it identifies the mobile payment app from traffic data, then classifies specific actions on the mobile payment app, and finally, detects the detailed steps within the action. In our proposed system, we extract reliable features from the collected traffic data generated on the mobile payment app, then use a series of well-performing ensemble learning strategies to deal with three identification tasks. Compared with prior works, the experimental results demonstrate that our proposed hierarchical identification system performs better.

摘要： Eclipse作为一款JavaIDE开发环境,受到越来越多程序员的喜爱。但是Eclipse对JNI开发的支持并不友好,很多操作都需要切换到控制台上输入命令来完成,并且不支持对Native函数的调试,这些不利因素无形中增加了JNI开发的成本与难度。文章基于国产平台,系统研究了Eclipse插件开发技术,根据JNI开发的特点,结合用户实际需求,在Eclipse中分别实现了JNI的可视化开发以及调试开发,从Java工程到C工程无缝衔接,界面友好、操作便利,实现了Eclipse环境下对JNI快速开发的支撑,增强了EclipseIDE的功能,丰富了国产平台的软件生态环境,对于国产平台的产业化发展具有重要的学术意义及应用价值。

关键词： Privacy   data mining   l-diversity   t-closeness  

摘要： A number of studies on privacy-preserving data mining have been proposed. Most of them assume that they can separate quasi-identifiers (QIDs) from sensitive attributes. For instance, they assume that address, job, and age are QIDs but are not sensitive attributes and that a disease name is a sensitive attribute but is not a QID. However, all of these attributes can have features that are both sensitive attributes and QIDs in practice. In this paper, we refer to these attributes as sensitive QIDs and we propose novel privacy models, namely, (l1, ... , lq)-diversity and (t1, ... , tq)-closeness, and a method that can treat sensitive QIDs. Our method is composed of two algorithms: An anonymization algorithm and a reconstruction algorithm. The anonymization algorithm, which is conducted by data holders, is simple but effective, whereas the reconstruction algorithm, which is conducted by data analyzers, can be conducted according to each data analyzer's objective. Our proposed method was experimentally evaluated using real data sets.

关键词： Output regulation   Linear systems   Adaptive systems   Internal model   Identification for control  

摘要： The problem of output regulation for general multivariable linear systems has been solved in the 70s, in the seminal works of Francis, Wonham and Davison, under the assumption that the reference signals and the disturbances acting on the system are generated by a known exogenous linear system (the exosystem). The regulator is designed to embed an internal model of the exosystem, which ensures that asymptotic regulation is maintained under arbitrary plant perturbations that do not destroy linearity and closed-loop stability. This robustness property, however, is inexorably lost whenever the internal model does not match exactly the exosystem. In this paper we endow the linear regulator with a discrete-time adaptive unit that adapts the regulator's internal model on the basis of the closed-loop evolution. Compared to existing approaches, adaptation here is cast as an identification problem, and the corresponding optimal predictor is designed independently from the underlying control system. This permits to separate stabilization and adaptation, thus naturally handling general non-square multivariable non minimum-phase plants. Closed-loop stability is guaranteed and, if the dimension of the internal model is large enough and a persistency of excitation condition is fulfilled, asymptotic regulation is achieved for references and disturbances generated by an unknown exosystem. Robustness to parametric uncertainties is inherited by the linear regulator and robustness to additional unmodeled disturbances is proved to hold. (C) 2019 Elsevier B.V. All rights reserved.

关键词： Parkinson's disease   Hyperhidrosis   Autonomic   Non-motor symptoms   Dyskinesia  

摘要： ObjectiveTo identify associated (non-)motor profiles of Parkinson's disease (PD) patients with hyperhidrosis as a dominant *** isa cross-sectional, exploratory, analysis of participants enrolled in the Non-motor Longitudinal International Study (NILS;UKCRN No: 10084) at the Parkinson's Centre at King's College Hospital (London, UK). Hyperhidrosis scores (yes/no) on question 28 of the Non-Motor Symptom Questionnaire were used to classify patients with normal sweat function (n=172) and excessive sweating (n=56) (Analysis 1;n=228). NMS scale (NMSS) question 30 scores were used to stratify participants based on hyperhidrosis severity (Analysis 2;n=352) using an arbitrary severity grading: absent score 0 (n=267), mild 1-4 (n=49), moderate 5-8 (n=17), and severe 9-12 (n=19). NMS burden, as well as PD sleep scale (PDSS) scores were then analysed along with other *** differences were observed in baseline demographics between groups in either analysis. Patients with hyperhidrosis exhibited significantly higher total NMSS burden compared to those without (p<0.001). Secondary analyses revealed higher dyskinesia scores, worse quality of life and PDSS scores, and higher anxiety and depression levels in hyperhidrosis patients (p<0.001). Tertiary analyses revealed higher NMSS item scores for fatigue, sleep initiation, restless legs, urinary urgency, and unexplained pain (p<0.001).ConclusionsChronic hyperhidrosis appears to be associated with a dysautonomia dominant subtype in PD patients, which is also associated with sleep disorders and a higher rate of dyskinesia (fluctuation-related hyperhidrosis). These data should prompt the concept of hyperhidrosis being used as a simple clinical screening tool to identify PD patients with autonomic symptoms.

摘要： This research considered a novel approach to network security by combining a new networking architecture based on the Identifier-Locator Network Protocol (ILNP) and the existing Domain Name System (DNS). Specifically, the investigations considered the mitigation of network-level and transport-level based Denial of Service (DoS) attacks. The solutions presented for DoS are applicable to secure servers that are visible externally from an enterprise network. DoS was chosen as an area of concern because in recent years DoS has become the most common and hard to defend against attacks. The novelty of this approach was to consider the way the DNS and ILNP can work together, transparently to the application, within an enterprise scenario. This was achieved by the introduction of a new application-level access control function - the Capability Management System (CMS) - which applies configuration at the application level (DNS data) and network level (ILNP namespaces). CMS provides dynamic, ephemeral identity and location information to clients and servers, in order to effectively partition legitimate traffic from attack traffic. This was achieved without modifying existing network components such as switches and routers and making standard use of existing functions, such as access control lists, and DNS servers, all within a single trust domain that is under the control of the enterprise. The prime objectives of this research were: • to defend against DoS attacks with the use of naming and DNS within an enterprise scenario. • to increase the attacker’s effort in launching a successful DoS attack. • to reduce the visibility of vulnerabilities that can be discovered by an attacker by active probing approaches. • to practically demonstrate the effectiveness of ILNP and DNS working together to provide a solution for DoS mitigation. The solution methodology is based on the use of network and transport level capabilities, dynamic changes to DNS data, and a Moving Target
