Abstract

Apparati, methods, and computer-readable media for improving the security of communications networks. In one embodiment, an application control device (1102) controls another device (1109) from a remote location. The system comprises a remote device (1101) coupled to the device (1109) being controlled. The remote device (1101) has an action portion (1103) and a security portion (1104). The security portion (1104) contains a unique security portion identifier (1142). Remotely situated from the remote device (1101), the application control device (1102) comprises a rolling transaction code generator (1120) adapted to assign a unique rolling transaction code to each occurrence for which the application control device (1102) wishes to control the action portion (1103) of the remote device (1101). Another embodiment is a system for enabling two or more devices (1401, 1402, 1403) to communicate with each other over a network (1450) without human intervention. The system comprises at least one sending device (1401) adapted to send messages (1460) over the network (1450) to at least one receiving device (1402). Each sending device (1401) is coupled to the network (1450) via a sending intelligent chip (1411). Each receiving device (1402) is coupled to the network (1450) via a receiving intelligent chip (1421). Sending intelligent chip (1411) appends an identifier (1417) to each message (1460) emanating from its associated sending device (1401). The identifier (1417) comprises a fixed portion (1415, 1416) uniquely identifying the associated sending device (1401), and a variable portion (1414). Receiving intelligent chip (1421) comprises a module (1423) for approving the sent messages (1460), by validating both the fixed and variable portions of the identifier (1417).

Dependent claims

A system wherein two or more devices communicate with each other over a network automatically and without human intervention, said system comprising:

at least one smart sending device adapted to send substantive original messages pertaining exclusively to said smart sending device, said messages being sent over the network to at least one smart receiving device, each smart sending device coupled to the network via an associated dedicated sending intelligent chip;
and
at least one smart receiving device coupled to the network via an associated dedicated receiving intelligent chip;
wherein
each sending intelligent chip appends an identifier to each message emanating from the smart sending device associated with said sending intelligent chip, said identifier comprising a fixed portion uniquely identifying the associated smart sending device, and a variable portion;
each sending intelligent chip comprises a clock for tracking the current date and time;
each sending intelligent chip digitizes the time tracking by the clock according to a time interval preselected by a user of the sending intelligent chip, and makes the digitized time the variable portion of the identifier;
