Multilevel Database Security for Android Using Fast Encryption Methods

Multilevel Security (MLS) is one of the ways that protects stored information in computer and mobile devices. It classifies users into levels security; thus, user can access within its level or less. A smartphone used managing some businesses, controlling home car devices smart city environment by using a set data database. The database more than authorized this confidential important requires protection from un users. In research proposed system to implement MLS principle three security presented. first gives own level. second transfers through parts according their (system administrator regular user). third allows manipulate encrypted SQLite simple quick cryptographic algorithm. implemented which are supported Android operating system. experimental result showed has ability protect prevents view at upper levels. Also, inability change leak lower Moreover, works quickly needs little storage space.
