Secure encrypted steganography graphical password scheme for near field communication smartphone access control system

摘要

A two-factor authentication near-field communication (NFC) smartphone access control system is proposed in this paper as an emerging alternative to traditional authentication schemes. The authors combine the usage of digital key cryptography with a proprietary encryption steganography graphical password (ESGP) scheme on the assumption that humans remember images better than numbers. The authors clearly present their idea and detail the proposed implementation, emphasizing the fact that the ESGP scheme is meant "to increase the security level of existing NFC smartphone access control systems."
