Isomorphic Security System

(Anti-Theft Protocols)

The Isomorphic Security System is part of the Anti-Theft Protocols. This program is a standard system in almost all Time Travel Capsules. If the Isomorphic Security System is activated, it will use a series of voice print and finger and palm print scanners to ensure that only authorized Time Lords can operate the Control Console. An optional part of this system allows parts (or all) of the console to be electrified using the Immobilizer Switch.

Even if an unauthorized user does manage to deactivate the Isomorphic Security System, the rest of the Anti-Theft Protocols will prevent the accurate piloting of the Capsule. It is difficult, but not impossible, to compensate for this system.

Many systems rely on Gallifreyan retinal scans to prime/activate them. There are several other Security Protocols, many of which can be customized by the operator. Security Protocol 712, for example, allows the ship to make an automatic flight to the coordinates outlined in an Authorized Control Disc.
