With the development of wireless communication technology, mobile devices have played more and more important roles in the people's daily lives. However, data storage and sharing are difficult for these devices due to the data inflation and natural limitations of mobile devices, such as limited storage space and computing capability. In this paper, the authors present a lightweight Cloud-based storage framework, which provides an easy-to-use file navigation service for attribute-based file querying or semantic-based data retrieving. Meanwhile, it incorporates an effective mechanism for users to verify their data integrity, which can relieve much burden from mobile devices.
