Beauty and the Beast: Diverting Modern Web Browsers to Build Unique Browser Fingerprints

Abstract: Worldwide, the number of people and the time spent browsing the web keeps increasing. Accordingly, the technologies to enrich the user experience are evolving at an amazing pace. Many of these evolutions provide for a more interactive web (e.g., boom of JavaScript libraries, weekly innovations in HTML5), a more available web (e.g., explosion of mobile devices), a more secure web (e.g., Flash is disappearing, NPAPI plugins are being deprecated), and a more private web (e.g., increased legislation against cookies, huge success of extensions such as Ghostery and AdBlock). Nevertheless, modern browser technologies, which provide the beauty and power of the web, also provide a darker side, a rich ecosystem of exploitable data that can be used to build unique browser fingerprints. Our work explores the validity of browser fingerprinting in today's environment. Over the past year, we have collected 118,934 fingerprints composed of 17 attributes gathered thanks to the most recent web technologies. We show that innovations in HTML5 provide access to highly discriminating attributes, notably with the use of the Canvas API which relies on multiple layers of the user's system. In addition, we show that browser fingerprinting is as effective on mobile devices as it is on desktops and laptops, albeit for radically different reasons due to their more constrained hardware and software environments. We also evaluate how browser fingerprinting could stop being a threat to user privacy if some technological evolutions continue (e.g., disappearance of plugins) or are embraced by browser vendors (e.g., standard HTTP headers).

The system develops the application through the application development UI. The application is developed with the ADF and is configured to be downloaded from a download location in the cloud system. The application is configured to be downloaded on a device as a native application.

Windows Instant Messaging App Forensics: Facebook and Skype as Case Studies.

Abstract: Instant messaging (IM) has changed the way people communicate with each other. However, the interactive and instant nature of these applications (apps) made them an attractive choice for malicious cyber activities such as phishing. The forensic examination of IM apps for modern Windows 8.1 (or later) has been largely unexplored, as the platform is relatively new. In this paper, we seek to determine the data remnants from the use of two popular Windows Store application software for instant messaging, namely Facebook and Skype on a Windows 8.1 client machine. This research contributes to an in-depth understanding of the types of terrestrial artefacts that are likely to remain after the use of instant messaging services and application software on a contemporary Windows operating system. Potential artefacts detected during the research include data relating to the installation or uninstallation of the instant messaging application software, log-in and log-off information, contact lists, conversations, and transferred files.

Mobile Computing Weight, Diet, Nutrition, and Exercise Management System With Enhanced Feedback and Goal Achieving Functionality

Abstract: An illustrative mobile computing device executing weight, nutrition, health, behavior and exercise application software serves as a simulated combination personal trainer and dietician/nutritionist for the user using comprehensive databases storing personalized health, nutrition and exercise information. A mobile computing device, such as a smartphone, executing such software monitors, tracks and/or adjusts caloric intake, energy expenditure taking into account nutritional information and behavioral factors. The mobile computing device receives food consumption, exercise-related, behavior and other input using speech input and the device's GPS subsystem to ease data entry burden on users and to promote continued long-term usage. The system rewards user goal achievement in an automatic, seamless manner, through, for example, downloading music, books, or other media. In illustrative implementations, the system assists users to make healthy food and exercise choices by using a comprehensive color code system to identify good choices, bad choices and those in between.

Towards a cognitive routing engine for software defined networks

Abstract: In Software Defined Networks (SDN), intensive traffic monitoring is used to optimize the Quality-of-Service (QoS) of the network paths which are selected. Thus, we introduce the use of the Cognitive Packet Network (CPN) algorithm to SDN in order to optimize the search for new high-QoS paths. We install the CPN algorithm in the Cognitive Routing Engine (CRE), a new application software for SDN, and show that with limited monitoring overhead we are able to determine the near-optimal paths for given QoS metrics that may be proposed by the end users. Measurements that we have conducted on an experimental replica of the GEANT network that our approach uses close to 10 times less monitoring data than conventional SDN, but that we are able to approach the optimal paths within 2%.

A Smartphone App and Cloud-Based Consultation System for Burn Injury Emergency Care

Abstract: BACKGROUND: Each year more than 10 million people worldwide are burned severely enough to require medical attention, with clinical outcomes noticeably worse in resource poor settings. Expert clinical advice on acute injuries can play a determinant role and there is a need for novel approaches that allow for timely access to advice. We developed an interactive mobile phone application that enables transfer of both patient data and pictures of a wound from the point-of-care to a remote burns expert who, in turn, provides advice back. METHODS AND RESULTS: The application is an integrated clinical decision support system that includes a mobile phone application and server software running in a cloud environment. The client application is installed on a smartphone and structured patient data and photographs can be captured in a protocol driven manner. The user can indicate the specific injured body surface(s) through a touchscreen interface and an integrated calculator estimates the total body surface area that the burn injury affects. Predefined standardised care advice including total fluid requirement is provided immediately by the software and the case data are relayed to a cloud server. A text message is automatically sent to a burn expert on call who then can access the cloud server with the smartphone app or a web browser, review the case and pictures, and respond with both structured and personalized advice to the health care professional at the point-of-care. CONCLUSIONS: In this article, we present the design of the smartphone and the server application alongside the type of structured patient data collected together with the pictures taken at point-of-care. We report on how the application will be introduced at point-of-care and how its clinical impact will be evaluated prior to roll out. Challenges, strengths and limitations of the system are identified that may help materialising or hinder the expected outcome to provide a solution for remote consultation on burns that can be integrated into routine acute clinical care and thereby promote equity in injury emergency care, a growing public health burden.

Maximizing quality of experience through context-aware mobile application scheduling in cloudlet infrastructure

Abstract: Application software execution requests, from mobile devices to cloud service providers, are often heterogeneous in terms of device, network, and application runtime contexts. These heterogeneous contexts include the remaining battery level of a mobile device, network signal strength it receives and quality-of-service QoS requirement of an application software submitted from that device. Scheduling such application software execution requests from many mobile devices on competent virtual machines to enhance user quality of experience QoE is a multi-constrained optimization problem. However, existing solutions in the literature either address utility maximization problem for service providers or optimize the application QoS levels, bypassing device-level and network-level contextual information. In this paper, a multi-objective nonlinear programming solution to the context-aware application software scheduling problem has been developed, namely, QoE and context-aware scheduling QCASH method, which minimizes the application execution times i.e., maximizes the QoE and maximizes the application execution success rate. To the best of our knowledge, QCASH is the first work in this domain that inscribes the optimal scheduling problem for mobile application software execution requests with three-dimensional context parameters. In QCASH, the context priority of each application is measured by applying min-max normalization and multiple linear regression models on three context parameters-battery level, network signal strength, and application QoS. Experimental results, found from simulation runs on CloudSim toolkit, demonstrate that the QCASH outperforms the state-of-the-art works well across the success rate, waiting time, and QoE.

Variability Mitigation in Nanometer CMOS Integrated Systems: A Survey of Techniques From Circuits to Software

Abstract: Variation in performance and power across manufactured parts and their operating conditions is an accepted reality in modern microelectronic manufacturing processes with geometries in nanometer scales. This article surveys challenges and opportunities in identifying variations, their effects and methods to combat these variations for improved microelectronic devices. We focus on computing devices and their design at various levels to combat variability. First, we provide a review of key concepts with particular emphasis on timing errors caused by various variability sources. We consider methods to predict and prevent, detect and correct, and finally conditions under which such errors can be accepted; we also consider their implications on cost, performance and quality. We provide a comparative evaluation of methods for deployment across various layers of the system from circuits, architecture, to application software. These can be combined in various ways to achieve specific goals related to observability and controllability of the variability effects, providing means to achieve cross-layer or hybrid resilience. We then provide examples of real world resilient single-core and parallel architectures. We find that parallel architectures and parallelism in general provide the best means to combat and exploit variability to design resilient and efficient systems. Using programmable accelerator architectures such as clustered processing elements and GP-GPUs, we show how system designers can coordinate propagation of timing error information and its effects along with new techniques for memoization (i.e., spatial or temporal reuse of computation). This discussion naturally leads to use of these techniques into emerging area of “approximate computing,” and how these can be used in building resilient and efficient computing systems. We conclude with an outlook for the emerging field.

Secure application acceleration system, methods and apparatus

Abstract: An improved storage controller that enables the acceleration of datacenter software, by making it easier to deploy application software portions (applets) onto storage devices, in a manner that best supports runtime performance acceleration of storage-network-latency-throttled applications. Means are defined for how server hosted applications cause to have provisioned, initiate execution of, and work with a multitude of applets on a multitude of storage devices, proximate to storage contents. This invention supports the multi-exabyte growth of data storage, by scaling performance acceleration linearly with the growth in the number of storage devices. This in turn supports the evolving cloud and Enterprise Cognitive Computing datacenter by providing the infrastructure necessary for accelerating applications that face enormous heterogeneous datasets. This includes Big Data Analytics of problems that have eluded successful analysis.

Optimization of Two-Granularity Software Rejuvenation Policy Based on the Markov Regenerative Process

Abstract: Software rejuvenation is a proactive software control technique that is used to improve a computing system performance when it suffers from software aging. In this paper, a two-granularity inspection-based software rejuvenation policy, which works as a closed-loop control technique, is proposed. This policy mitigates the negative impact of two-level software aging. The two levels considered are the user-level applications and the operating system. A Markov regenerative process model is constructed based on the system condition. We obtain the degradation rate of the application software and operating system from fault injection experiments. The diagnostic accuracy of the adopted monitor and analysis system, which is applied to inspect the application software and operating system, is considered as we provide the optimal rejuvenation strategies. Finally, the availability and the overall loss probability with their corresponding optimal inspection time intervals are obtained numerically based on the parameter values estimated from the experiments. Experimental results show that two-granularity software rejuvenation is much more effective than traditional single-level software rejuvenation. In our experi-mental study, when two-granularity software rejuvenation is used, the unavailability and the overall loss probability of the system were reduced by 17.9% and 2.65%, respectively, in comparison with the single-level rejuvenation.

Power Consumption Based Android Malware Detection

Abstract: In order to solve the problem that Android platform’s sand-box mechanism prevents security protection software from accessing effective information to detect malware, this paper proposes a malicious software detection method based on power consumption. Firstly, the mobile battery consumption status information was obtained, and the Gaussian mixture model GMM was built by using Mel frequency cepstral coefficients MFCC. Then, the GMM was used to analyze power consumption; malicious software can be classified and detected through classification processing. Experiment results demonstrate that the function of an application and its power consumption have a close relationship, and our method can detect some typical malicious application software accurately.

A Programming Framework for Large Scale Numerical Simulations on Unstructured Mesh

Abstract: The performance of parallel computers grows rapidly. However, application software is lagging behind due to two bottlenecks: "performance wall" and "programmability wall". These bottlenecks have prevented a lot of application software from achieving good performance and fast development. Programming framework is considered an effective approach to overcome the above bottlenecks. In this paper, we give a prototype of JAUMIN, which is a programming framework for large scale application software based on unstructured mesh. Some important technologies of JAUMIN will be presented, including distributed data structures, data communication patterns and application programming interfaces. Finally, some applications based on JAUMIN will be demonstrated to show that JAUMIN can accelerate the development of application software greatly and support effective simulation on petascale supercomputer.

A rigorous and efficient run-time security monitor for real-time critical embedded system applications

Abstract: We introduce a run-time security monitor for embedded system applications that detects both known and unknown computational cyber-attacks. Our security monitor is rigorous (i.e. sound and complete), eliminating false alarms, as well as efficient, supporting real-time detection. In contrast, conventional run-time security monitors for application software either produce (high rates of) false alarms (e.g. intrusion detection systems) or limit application performance (e.g. run-time verification systems). Such monitors are typically non-adaptive against constantly changing attacks of variable extent. Our run-time monitor detects attacks by checking the consistency between the application run-time behavior and its specified (expected) behavior model. Our specification language is based on monadic second order logic and event calculus interpreted over algebraic data structures; the application implementation can be in any programming language. Based on our defined denotational semantics of the specification language, we prove that the security monitor is sound and complete, i.e. it produces an alarm iff it detects an inconsistency between the application execution and the specified behavior. Importantly, the monitor detects not only cyber-attacks but all behavioral deviations from specification, e.g. bugs, and so, is readily applicable to the security of legacy systems. Through an application of our prototype monitor to a PID controller for a feedwater tank, we demonstrate that rigorous run-time monitors employing verification techniques are effective, efficient and readily applicable to demanding real-time critical systems, without scalability limitations.

Through the technical scheme provided by embodiments of the invention, the upgrade process of the operation system is directly called to upgrade the application software, and a prompt interface of installation control is skipped, so that the batch download and silent upgrade of the application software required to be upgraded are realized, and the software installation efficiency is improved.

Online Test of Control Flow Errors: A New Debug Interface-Based Approach

Abstract: Detecting the effects of transient faults is a key point in many processor-based safety-critical applications. This paper proposes to adopt the debug interface module existing today in several processors/controllers available on the market. In this way, we can achieve a good detection capability and small latency with respect to control flow errors, while the cost for adopting the proposed technique is rather limited and does not involve any change either in the processor hardware or in the application software. The method works even if the processor uses caches and we experimentally evaluated its characteristics demonstrating the advantages and showing the limitations on two pipelined processors. Experimental results performed by fault injection using different software applications demonstrate that the method is able to archieve high fault coverage (more than 95 percent in nearly all the considered cases) with a limited cost in terms of area and performance degradation.

Willingness to use mobile application for smartphone for improving road safety

Abstract: In the last few years mobile devices have reached a large amount of consumers in both developed and high-growth world economies. In 2013, 97% of the Italian population owns a mobile phone, and 62% owns a smartphone. Application software for mobile devices is largely proposed to consumers, and several mobile applications were oriented toward the improvement of road safety and road accident risk reduction. In this paper, we describe the results of a survey oriented to preventively investigate on the willingness to receive and/or to give information about road condition by means of mobile devices. Road users were informed about the characteristics of a mobile application, and then they were invited to complete a questionnaire. Experimental data were used for capturing road user attitudes toward the use of the smartphone to improve road safety, and to establish the preferences for the different features of the proposed mobile application. To this end, we choose to use the ordered probit model methodology. We demonstrate that the adopted methodology accounts for the differential impacts of the willingness to receive and/or to give information about road conditions on the overall willingness to receive and/or to give information through an application software for mobile devices.

SDN-based vs. software-only EPC gateways: A cost analysis

Abstract: Technologies like software defined networking and cloud computing allow for new approaches in mobile network design. A key driver for bringing mobile networks into the cloud is the expected cost reduction resulting from economies of scale: all software run on commercial off-the-shelf server which can be accumulated in one or more datacenters with all of those having a similar setup, minimizing the administrative costs. Deploying mobile core control functions as applications in datacenters already proved to be viable and economic. However, the evolved packet core (EPC), which mostly comprises gateways, holds a special challenge, since there is a strong interaction between forwarding plane and control functions. Having those functions as application software running on servers in datacenters induces the risk that cost reductions from virtualization are offset by costs of additional transport and processing. This paper analyzes the total cost of ownership of several variants of virtualized EPC gateways for a country-scale mobile network covering Japan. The cost model presented can serve as guideline to understand the economic aspects of future virtual network function deployments.

A Model-Driven Framework to Develop Personalized Health Monitoring

Abstract: Both distributed healthcare systems and the Internet of Things (IoT) are currently hot topics. The latter is a new computing paradigm to enable advanced capabilities in engineering various applications, including those for healthcare. For such systems, the core social requirement is the privacy/security of the patient information along with the technical requirements (e.g., energy consumption) and capabilities for adaptability and personalization. Typically, the functionality of the systems is predefined by the patient’s data collected using sensor networks along with medical instrumentation; then, the data is transferred through the Internet for treatment and decision-making. Therefore, systems creation is indeed challenging. In this paper, we propose a model-driven framework to develop the IoT-based prototype and its reference architecture for personalized health monitoring (PHM) applications. The framework contains a multi-layered structure with feature-based modeling and feature model transformations at the top and the application software generation at the bottom. We have validated the framework using available tools and developed an experimental PHM to test some aspects of the functionality of the reference architecture in real time. The main contribution of the paper is the development of the model-driven computational framework with emphasis on the synergistic effect of security and energy issues.

Finding Resilience-Friendly Compiler Optimizations Using Meta-Heuristic Search Techniques

Abstract: With the projected future increase in hardware error rates, application software needs to be resilient to hardware faults. An important factor affecting an application's error resilience and vulnerability is the set of optimizations used when compiling it. We propose an automated technique based on genetic algorithms to find the application-specific set of compiler optimizations that can boost performance without degrading the application's error resilience. We find that the resulting optimized code has significantly better error resilience than when being compiled with the standard optimization levels (i.e., O1, O2, O3), while attaining comparable performance improvements, thus leading to lower overall vulnerabilities.

However there are some cases where the mobile internet banking apps occurred some problems that might cause loss of money. Therefore, in this paper we will examine issues on the architecture, and some security issues of mobile internet banking apps. And then we will explore some security measuras to deal with the associated security challenges.
