A cloud-based system for enhancing security of Android devices

Abstract

As the functions of smart mobile devices become stronger, the security issues of devices become more prominent. Compared with PC, the mobile device has its own features. The speed, storage and power of mobile devices are limited, so it's not suitable for running large-scale resource-intensive security applications on the mobile devices. In this paper, we implement a system based on cloud, which runs a large number of security functions on the cloud instead of the Android devices. The system can detect malicious applications, filter malicious Websites, and safeguard the network and device data security. Most of the functions are done by cloud. Compared with the common security applications run on the Android devices, the system can not only enhance the safety of the devices, but also reduce the system load of the devices.
