Design and Implementation of File Multi-Cloud Storage System Based on Android

摘要

With the rapid development of the Internet, cloud computing and cloud storage technology have been widely used in different fields. How to effectively use cloud storage technology on mobile devices has also become a research hotspot. To solve the problem of data security, integrity, confidentiality, and user data inaccessibility cause by the suspension of cloud service provider operations during cloud storage. This paper designs a file multi-cloud storage system based on Android, which uses RS (Reed Solomon) erasure coding to block, encode and encrypt data, and then store them in multiple cloud servers. Using Android to call the DLL (Dynamic Link Library) to realize the application of RS erasure coding / decoding in the system. The system has a good effect after running, which has certain guiding significance for the development of the mobile multi-cloud storage system.
