Sharing emergency or disaster information in a timely manner is very important to people's life. With more and more people carrying a smart phone on daily basis, an emergency and disaster information sharing system accessible to smart phone users is necessary and could be very useful. This project is to construct a disaster and emergency information website that allows smart phone users to uplo...

Abstract: The applications in Android based smartphones generate unique IO requests; however, existing IO workload generators and trace capturing tools are designed to neither generate nor capture the IO requests of Android apps. In this paper, we introduce the Android storage performance analysis Tool (AndroStep) which is specifically designed for characterizing and analyzing the behavior of t...

BACKGROUND Fat accumulation in android compartments may confer increased metabolic risk. The incremental utility of measuring regional fat deposition in association with metabolic syndrome (MS) has not been well described particularly in an elderly population. METHODS AND FINDINGS As part of the Korean Longitudinal Study on Health and Aging, which is a community-based cohort study of people a...

Android operating system has the highest market share in 2014; making it the most widely used mobile operating system in the world. This fact makes Android users the biggest target group for malware developers. Trend analyses show large increase in mobile malware targeting the Android platform. Android's security mechanism is based on an instrument that informs users about which permissions the...

Covert channels have been used as a means to circumvent security measures and leak sensitive data undetectable to an onlooker. While these channels have been used in a lot of networks, their applications on mobile devices have just started to be seen. Recently, many covert channels in Android systems have been presented utilizing various available system resources. This demo aims to show how a ...

The feasibility and preliminary efficacy of an android robot-mediated mock job interview training in terms of both bolstering self-confidence and reducing biological levels of stress in comparison to a psycho-educational approach human interview was assessed in a randomized study. Young adults (ages 18-25 years) with autism spectrum disorder (ASD) were randomized to participate either in a mock...

The success of Android phones makes them a prominent target for malicious software, in particular since the Android permission system turned out to be inadequate to protect the user against security and privacy threats. This work presents AppGuard, a powerful and flexible system for the enforcement of user-customizable security policies on untrusted Android applications. AppGuard does not requi...

In this work, we optimise the Android IO stack for user-level filesystem. Android imposes user-level filesystem over native filesystem partition to provide flexibility in managing the internal storage space and to maintain host compatibility. The overhead of user-level filesystem is prohibitively large and the native storage bandwidth is significantly under-utilised. We overhauled the FUSE laye...

Todaymost mobile operating systems provide an application portal (e.g. Android Market, A ppStore) where users can search by ke ywords and e xplicitly rate applications published by third-party developers. In this paper we go be yond this approach and introduce an implicit rating mechanism for Android programs. Our a pproach, c aptures installation, upd ate, a nd removal e vents, a nd allows to ...
