With the rapid development of augmented reality (AR) technology, AR picture books have new development possibilities, yet limited research exists on the purchase intention of adult readers of AR picture books. Based on the information system success model and the perceived value theory, this study integrates the design features of AR picture books into causal configuration, and constructs a structural model using perceived emotional value and perceived functional value as the intermediary variables. Based on the valid data of 327 adult readers, partial least squares structural equation modeling (PLS-SEM) was used to empirically analyze the structural model. The results show that aesthetic quality, interaction quality, information quality and narrative quality are the key factors affecting purchase intention, and perceived emotional value and perceived functional value play a mediating role. The results of this study provide rich theoretical and practical insights for the design and marketing strategies of AR picture books.

A fast-growing demand from smartphone users is mobile virtualization.This technique supports running separate instances of virtual phone environments on the same device. In this way, users can run multiple copies of the same app simultaneously,and they can also run an untrusted app in an isolated virtual phone without causing damages to other apps. Traditional hypervisor-based virtualization is impractical to resource-constrained mobile devices.Recent app-level virtualization efforts suffer from the weak isolation mechanism. In contrast, container-based virtualization offers an isolated virtual environment with superior performance.However, existing Android containers do not meet the anti-evasion requirement for security applications: their designs are inherently incapable of providing transparency or stealthiness.

Repackaging popular benign apps with malicious payload used to be the most common way to spread Android malware. Nevertheless, since 2016, we have observed an alarming new trend to Android ecosystem: a growing number of Android malware samples abuse recent app-virtualization innovation as a new distribution channel. App-virtualization enables a user to run multiple copies of the same app on a single device, and tens of millions of users are enjoying this convenience. However, cybercriminals repackage various malicious APK files as plugins into an app-virtualization platform, which is flexible to launch arbitrary plugins without the hassle of installation. This new style of repackaging gains the ability to bypass anti-malware scanners by hiding the grafted malicious payload in plugins, and it also defies the basic premise embodied by existing repackaged app detection solutions.
