Study on Sensitive Data Protection Based on SEAndroid

Abstract

Smart mobile terminals are growing rapidly. Nowadays Android has been the leading role in mobile system market with an extremely large user scale. Consequently, large amounts of sensitive data stored in mobile devices are facing an increasing number of threats. Those sensitive data contains not only personal information like contacts and sms, but also some high-level security information in IoT (Internet of Things) devices, even bank accounts and passwords. In this paper, we designed our Sensitive Data Protection mechanism (SDP) based on SELinux in Android (SEAndroid), which can significantly enhance the protection for the static sensitive data in Android system and help Android spread further in smart mobile terminal field.
