A multicentre study on the epidemiology of perinatal depression was conducted among Japanese women expecting the first baby (N = 290). The incidence rate of the onset of the DSM-III-R Major Depressive Episode during pregnancy (antenatal depression) and within 3 months after delivery (postnatal depression) were 5.6% and 5.0%, respectively. Women with antenatal depression were characterised by young age and negative attitude towards the current pregnancy, whereas women with postnatal depression were characterised by poor accommodation, dissatisfaction with sex of the newborn baby and with the emotional undermining. Antenatal depression was a major risk factor for postnatal depression.
Hybrid application frameworks such as Cordova allow mobile application (app) developers to create platformindependent apps. The code is written in JavaScript, with special APIs to access device resources in a platform-agnostic way. In this paper, we present a novel app-repackaging attack that repackages hybrid apps with malicious code; this code can exploit Cordova's plugin interface to tamper with device resources. We further demonstrate a defense against this attack through the use of a novel runtime access control mechanism that restricts access based on the mobile user's judgement. Our mechanism is easy to introduce to existing Cordova apps, and allows developers to produce apps that are resistant to app-repackaging attacks.
Hybrid application frameworks such as Cordova are more and more popular to create platform-independent applications (apps) because they provide special APIs to access device resources in a platform-agonistic way. By using these APIs, hybrid apps can access device resources through JavaScript. In this paper, we present a novel apprepackaging attack that repackages hybrid apps with malicious code; this code can exploit Cordova's plugin interface to steal and tamper with device resources. We address this attack and cross-site scripting attacks against hybrid apps. Since these attacks need to use plugins to access device resources, we refer to both of these attacks as Cordova plugin attacks. We further demonstrate a defense against Cordova plugin attacks through the use of a novel runtime access control mechanism that restricts access based on the mobile user's judgement. Our mechanism is easy to introduce to existing Cordova apps, and allows developers to produce apps that are resistant to Cordova plugin attacks. Moreover, we evaluate the effectiveness and performance of our mechanism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
