Claim:
1. A mechanical locking device for a computer Input/Output (I/O) port, comprising: a casing configured for mechanical insertion of a secure member into the computer I/O port to physically block the computer I/O port; a securing mechanical locking mechanism disposed within the casing, the securing mechanical locking mechanism comprising: a locking element configured to engage the computer I/O port in a locked condition and to disengage from the computer I/O port in an unlocked condition; and a flex actuator wire of shape memory configured to cause the locking element to move between the locked condition and the unlocked condition, and wherein upon receiving authentication credentials from an external computing device, a first flex actuator wire of shape memory causes the locking element to move from the locked condition to the unlocked condition in response to a successful validation of the authentication credentials and a thermally activated second actuator prevents the locking element from moving to the unlocked condition due to the application of external heat by having a lower thermal activation temperature and a higher activation force from a shape memory wire of the second actuator than from the first flex actuator wire of shape memory.
