International Classification:

H04K 1/00

US Classification:

713185, 713182, 713166, 713168, 726 2, 726 9, 705 65, 705 69, 380 44, 380262, 380277, 380281

Abstract:

A system and method for preventing interception and decryption of information by an unauthorized party when that information is transmitted over a network is provided. A token is used to encrypt one-time password that is different for each network session, to prevent decryption thereof. The encrypted one-time password is returned to a network server for authentication by the server. The network server generates its response in a similar fashion. The server compares its response to the one-time password, to determine if they match. If they match, then the client is granted access to the network. If they responses do not match, then the client is denied access to the network by the server.

International Classification:

G06F 7/08

US Classification:

235381, 235383

Abstract:

An audit system for a vending machine system is provided. This audit system is configured to retrieve operational data, such as a DEX file, from a vending machine controller in the vending machine system. The audit system is further configured to store a communications log of the data transmitted between the vending machine controller and the audit system. This communications log can be used by an operator at a host system to assist in debugging communication errors between the audit system and the vending machine controller.

Assignee:

Authenex, Inc. - Hayward CA

International Classification:

H04L 29/00

US Classification:

726 2, 713168

Abstract:

A system and method for controlling access to multiple public networks and for controlling access to multiple private networks is provided. Authentication is used with unique public shared secrets and unique private shared secrets to control access to the networks. The invention includes a user device for communicating with at least a public network and/or a private network. The device may be capable of accessing multiple networks through one or more private networks with multiple access control servers. The user device must provide a correct response to each access control server, before access to the network may be granted. The device generates a one-time password, or response, to gain access to a controlled network server. The response generated by the device is matched to a response generated by an access control server that may have generated a challenge that prompted the response. If the two responses match, the device is authenticated and a user of the device is granted access to the network server.

International Classification:

G08B 13/08

US Classification:

3405451, 700236

Abstract:

A vending machine door monitoring system for an audit system is provided. This door monitoring system may utilize the same door switch utilized by the vending machine controller (VMC) in order to detect the state of an access door for the vending machine. This door monitoring system may have a separate power supply for applying a back-up voltage to a door circuit in the event that the VMC fails to supply the voltage. The door monitoring system may be further configured to detect a state of the door circuit regardless of the order in which the terminals from the door switch are coupled to the audit system.

US Classification:

700241, 705 28, 705 9, 701200, 701202

Abstract:

Techniques are provided for calculating vending machines' service priorities and scheduling the vending machines for service taking into account a number of factors and thresholds (). In some embodiments, the machines () are subdivided into subroutes (). Each subroute has one or more machines, and at least one subroute has a plurality of machines. The vending machine service schedule is generated by selecting the highest priority subroute () and selecting the machines in that subroute (). Other subroutes can be selected () if there is time left in the Service Period.

Abstract:

Systems and methods for remotely managing a vending machine system are provided. A host system transmits control data to an audit system installed in a vending machine system. This control data is used to modify a data collection parameter of the audit system, such as modifying alert conditions, reporting schedules, and filter terms used to parse DEX files received from a vending machine controller.
