Abstract: A secured virtual communication space system for secured communications between a plurality of communication devices communicating over a network aimed at preventing malicious communication activities previously classified as unlawful. The system comprises a plurality of control devices protected from unauthorized tampering, each control device connected to a communication device. The control device is adapted to preclude any action or obligatory execute actions with one common aim to prevent any possibility of malicious activity launched from the particular communication device it is connected to. The precluded or obligatory executed actions consist of predetermined rules—collective security code common to all control devices.

Abstract: An actuating device has a cartridge within a fixed casing. A card-like key has a key formation which, during insertion of the key into the cartridge, displaces a finger formation connected to an interference formation, which is then aligned with a gate of a gate member fixed to the casing. The gate allows passage to the interference formation allowing the cartridge to be displaced in unison with the key. An actuating formation on the cartridge is provided to actuate a lock or similar device.
