The malware threat for mobile phones is expected to increase with the great functionality enhancement of mobile phones. Despite the nowadays malware high abilities, there are a lot of challenges that facing the mobile threat containment process. From this perspective, this work introduces a novel effective solution for discovering handset malwares threats. The work proposed a new behavior based...

Over the past decade, security and privacy concerns about the growing deployment of biometrics as a proof of identity have motivated researchers to investigate solutions such as cancellable biometrics to enhance the security of biometric systems. However, the open nature of newly emerged mobile authentication scenarios has made these solutions impractical and necessitated the need for new innov...

The aim of the study was to evaluate factors which affect adoption and usage mobile money services by artisan gold miners in Zimbabwe with reference Umzingwane district. adopted a sequential explanatory research design an objective using mixed approach. Data gathered questionnaires from two hundred seventy (270) miners. consisted both open ended closed questions. revealed that district are lite...

Development of small antennas for mobile phones has received a lot of attention during the last few years due to size reduction of the handsets, requirements to keep the amount of RF power absorbed by the user below standardized levels regardless of the handset size, and introduction of multimode phones. Single-band and dual-band phones in which the external whip or helix antenna has been repla...

A simultaneous measurement method using parallel modulated probe array has been proposed to measure the electromagnetic radiation rapidly. Each modulated probe is excited by a local signal with individual frequency, so that the received IF signal contains different frequency components which indicate the relative magnitude of the RF signal at positions of the probes, and all the IF components a...

How did we arrive at our current state of tHe art? Pre-Cellular Mobile Telephony In order to understand where we're going, we need to understand how we arrived at today's state of the art. The notion of reliable mobile telephone service was first introduced in the 1950's. The first widely deployed system was developed by AT&T Bell Laboratories in the United States and referred to as Mobile Tele...

Utilizing rich end user context information is viewed as one of the necessary approaches in developing more personalized mobile services and user experiences. The practical impact of end user context research and new opportunities in the field provided by emerging data collection methods such as handset-based measurements (i.e., collecting usage data directly from the end users’ devices) have i...

Handsets which are not seen in the training phase (a.k.a unseen handsets) are main sources of performance degradation for speaker identification (SID) applications in telecommunication environments. To alleviate the problem, a soft-decision a priori knowledge interpolation (SD-AKI) method of handset characteristic estimation for handset mismatch-compensated SID is proposed in this paper. The id...

This paper describes two corpora collected at Lincoln Laboratory for the study of handset transducer e ects on the speech signal: the handset TIMIT (HTIMIT) corpus and the Lincoln Laboratory Handset Database (LLHDB). The goal of these corpora are to minimize all confounding factors and produce speech predominately di ering only in handset transducer e ects. The speech is recorded directly from ...
