Available in PDF, EPUB and Kindle. Book excerpt: This groundbreaking text examines the problem of user authentication from a completely new viewpoint. Rather than describing the requirements, technologies and implementation issues of designing point-of-entry authentication, the book introduces and investigates the technological requirements of implementing transparent user authentication – where authentication credentials are captured during a user’s normal interaction with a system. This approach would transform user authentication from a binary point-of-entry decision to a continuous identity confidence measure. Topics and features: discusses the need for user authentication; reviews existing authentication approaches; introduces novel behavioural biometrics techniques; examines the wider system-specific issues with designing large-scale multimodal authentication systems; concludes with a look to the future of user authentication.

Available in PDF, EPUB and Kindle. Book excerpt: Mobile devices (e.g., smartphones and tablets) are pervasive today, continuously opening up immense opportunities for everyday users. Their burgeoning popularity, however, brings forth various security and privacy threats. One well-established threat is of mobile malware (a form of insider attack) -- malicious apps that may surreptitiously misuse the sensitive resources and services available on the device. Other threats relate to unauthorized access of the device (outsider attacks) by a malicious entity in close physical proximity to the device, or having (temporary or permanent) physical possession of the device. The traditional defensive mechanisms, such as existing anti-virus software, distance-bounding protocols or passwords, are not sufficient to defeat these threats. This dissertation work explores the notion of "context" -- a potentially unique signature of a benign usage scenario -- to address insider-outsider attacks against mobile devices without undermining the overall usability of these devices. Our proposed defense system automatically detects the presence of a valid context using the information acquired by device’s many on-board sensors; the absence of such a context being indicative of malicious usage. Depending upon the application scenario, we elicit the context provided, explicitly or transparently, by the device user (e.g., a hand gesture or body movement), or captured from the device’s ambient environmental attributes (e.g., audio, temperature or altitude). When applicable, we use machine learning techniques and sensor fusion approaches towards designing a highly robust contextual mobile security system. To be specific, this dissertation work comprises four parts: (1) enhancing mobile app authorization using implicit/explicit context, (2) enhancing user authentication using transparent implicit context, (3) enhancing co-presence detection using environmental context, and (4) strengthening the contextual security adversarial models and evaluating the context detection systems against such strong models. In the first part, we present the design, implementation and evaluation of our contextual security mechanisms to defeat mobile malware attacks against prominent phone resources/services, namely, phone calls, camera and NFC payments. We use explicit as well as implicit context to detect user-friendly explicit gestures or transparent gesture so as to ascertain if the app requesting the permission to a sensitive resource is legitimate (and not malicious). In the second part, we present the design, implementation and evaluation of schemes to authenticate users transparently in the case of mobile (NFC) payments and zero-interaction authentication systems. In the third part, we present the design, implementation and evaluation of our co-presence detection system using different environmental context to thwart outsider "relay attacks" against mobile zerointeraction authentication systems and mobile payment systems. In the fourth part, we stretch the limits of the contextual security threat model to incorporate adversaries who may be capable of actively manipulating the context or underlying sensor data (internally or externally). Further, we present our insights to defend against such strong adversaries.

Download or read book Mobile Applications written by Tejinder S. Randhawa and published by Springer Nature. This book was released on 2022-08-17 with total page 669 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Android as a reference, this book teaches the development of mobile apps designed to be responsive, trustworthy and robust, and optimized for maintainability. As the share of mission-critical mobile apps continues to increase in the ever-expanding mobile app ecosystem, it has become imperative that processes and procedures to assure their reliance are developed and included in the software life cycle at opportune times. Memory, CPU, battery life and screen size limitations of smartphones coupled with volatility associated with mobile environments underlines that the quality assurance strategies that proved to be successful for desktop applications may no longer be effective in mobile apps. To that effect, this book lays a foundation upon which quality assurance processes and procedures for mobile apps could be devised. This foundation is composed of analytical models, experimental test-beds and software solutions. Analytical models proposed in the literature to predict software quality are studied and adapted for mobile apps. The efficacy of these analytical models in prejudging the operations of mobile apps under design and development is evaluated. A comprehensive test suite is presented that empirically assesses a mobile app’s compliance to its quality expectations. Test procedures to measure quality attributes such as maintainability, usability, performance, scalability, reliability, availability and security, are detailed. Utilization of test tools provided in Android Studio as well as third-party vendors in constructing the corresponding test-beds is highlighted. An in-depth exploration of utilities, services and frameworks available on Android is conducted, and the results of their parametrization observed through experimentation to construct quality assurance solutions are presented. Experimental development of some example mobile apps is conducted to gauge adoption of process models and determine favorable opportunities for integrating the quality assurance processes and procedures in the mobile app life cycle. The role of automation in testing, integration, deployment and configuration management is demonstrated to offset cost overheads of integrating quality assurance process in the life cycle of mobile apps.

Download or read book Evaluating Re authentication Strategies for Smartphones written by Lalit Agarwal and published by . This book was released on 2016 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Re-authenticating users may be necessary for smartphone authentication schemes that leverage user behavior, device context, or task sensitivity. However, due to the unpredictable nature of re-authentication, users may get annoyed when they have to use the default, non-transparent authentication prompt for re-authentication. We address this concern by proposing a few configurations with varying levels of screen transparency and time delays when displaying the authentication prompt. We conduct user studies with 30 participants to evaluate the usability and security of these configurations. We also study whether the user preferences of the configurations vary depending on the application the participants are using on their device or their surrounding environment. We find that the participants generally prefer the authentication configuration with a non-transparent background for sensitive applications, such as banking and photo apps. Our findings also indicate that the user preferences are inclined towards convenient, usable configurations while participants are using their devices at home. Though we did not observe any significant differences in the task completion overhead and context switch overhead among our proposed configurations, we find that participants utilize the time delay just before the authentication prompt is going to appear to complete their current task. We also provide implementation details of our Android lock library, FireLock, which developers can use to re-authenticate users while they are using their app. We conclude with suggestions to improve the design of the proposed configurations as well as a discussion of other mechanisms to notify the users in case of re-authentication.
