Abstract: A cyber-physical security module includes an input interface configured to connect to a signal source to intercept a physical signal that is transmitted from the signal source to a signal destination. An output interface is configured to connect to the signal destination. A programmable processor is configured to receive input from an administrator device to define or modify one or a plurality of security rules. Upon interception of the physical signal via the input interface, the processor is configured to apply the security rules to authenticate the intercepted physical signal. If the intercepted physical signal is authenticated, the processor is configured to transmit the intercepted physical signal to the signal destination via the output interface.

Abstract: A method for authorizing a single action by a plurality of users at a site may include registering each of the users and at least one mobile communication device associated with that user with an authorization module, identifying the mobile communication device by a unique hardware identification number. The method may also include associating each of the users and the mobile communication device associated with that user with the site by the authorization module. The method may further include requesting each of the users to confirm the action by sending a confirmation request from the site to the mobile communication device associated with that user by the authorization module. The method may also include authorizing the action upon receiving confirmation from the mobile communication devices of all users that are required to authorize that action.

Abstract: A method for guardian control over an electronic action includes registering one or more guardians and at least one mobile communication device associated with each guardian with an authorization module hosted on an authorization server. Each mobile communication device is identified by a unique hardware identification number. An authentication request for a supervised client that is attempting to perform the electronic action at a site is received by the authorization server from a site. A confirmation request is sent from the authorization server to the mobile communication device requesting the guardian to confirm the action. The action is authorized upon receiving confirmation from the mobile communication device.
