Yeah, the research paper notes that they need to implement 'coercion detection'. From page 12: "Since our aim is to prevent users from effectively transmitting the ability to authenticate to others, there remains an attack where an adversary coerces a user to authenticate while they are under ad- versary control. It is possible to reduce the effective- ness of this technique if the system could detect if the user is under duress. Some behaviors such as timed re- sponses to stimuli may detectably change when the user is under duress."
