Security Protocol 712

Security Protocol 712 was a security feature aboard The TARDIS which would cause the ship to dematerialize and re-appear at a predetermined point in space and time without it's pilot when activated. It could be programmed to be triggered by different events or objects such as Sally Sparrow's DVDs (TV: Blink) or the detonation of the Echelon Device. (TV: Before the Flood)

It was shown to have the same mild artificial intelligence as other TARDIS protocols such as the Voice Interface and Emergency Program One. As with most TARDIS emergency programs and protocols it utilized a holographic projection of the current incarnation of The Doctor to deliver it's message before takeoff.
