Annotation: 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.
