A Biometric-Based Data Protection Scheme for RSDs

Removable Storage Devices are widely used for data storage and sharing in mobile internet. The security of data stored in RSDs is a crucial issue in the field of information security and data protection. Considering that data encryption is ubiquitous for RSDs products, key management has become a challenge. Specially the storing key inside RSDs is not secure if the RSDs are stolen and controlled by attackers. This paper proposes a biometric-based authentication and key management scheme for RSDs data protection with the aim of ensuring that unauthorized users cannot access the plaintext data under any circumstance. Only the legal user with correct biometric features has access to the plaintext data by a client PC. Besides, the performance and security of the proposed scheme are analyzed.
