MOBILE DEVICE USER DATA PROTECTION APPROACH BASED ON MULTI-FACTOR AUTHENTICATION, VISUAL CRYPTOGRAPHY AND STEGANOGRAPHY

This paper presents a new approach for protecting user data of mobile phones. It combines
multi-factor authentication, secret sharing, visual cryptography, steganography and uses
built-in secure modules of the Android operating system. The proposed protocol ensures privacy of
user data even if the mobile phone and its associated storage server are compromised
