Toward mobile smart data file protection box

摘要

Aiming at this urgent need of the security protection of mobile intelligent terminal data file, we design a file security box to protect and manage important files in smartphones. The main functions of this file security box are: 1) fingerprint verification; 2) file management; 3) efficient encryption and decryption; 4) adaptive cipher algorithms; 5) separate logical document library; 6) updating the secret key regularly; 7) storing the key securely; 8) reinforcing the safety in enterprise level. Functional tests and performance tests show that the file security box we designed can not only achieve all of the above functionality with excellent user transparency and friendliness but also ensure the safety of important files without effecting users' experience.
