Voice trigger

[PacoBell]

I want to address one particular threat model that doesn't seem to have been brought up here. What if an attacker snatches the device from you and you never have enough time to physically trigger Ripple? Shouldn't there be a contingency for that situation? I'm thinking there should always be a covert, secondary, two-step trigger that's initially activated by detection of rapid device acceleration. Then the user could have the opportunity to shout a trigger phrase like "Sic semper tyrannis", "Dracarys", etc. to initiate panic lockdown. Of course, this doesn't solve the situation where the attacker incapacitates you first, but it is another potential tool in your privacy arsenal. The more paranoid can probably just set a dead-man's timeout in that case.
