Each password is encrypted with a new fresh key on the user's mobile device
combines all different methods of user authentication to create a more robust digital vault for personal data
The keys are stored in our servers
user can backing up the encrypted passwords
user only needs to utter the name
biggest advantage
the user need not assume any trust to neither our servers nor any cloud storage
no need to enter a master password every time since speaker recognition is used
authentication key K1
encryption key K2
Results
true positive rate (TPR) ≈ 1
false positive rate (FPR) ≈ 0
threshold θ = 0.6
