US Patent:

7231526, Jun 12, 2007
Filed:

Oct 25, 2002
Appl. No.:

10/280590
Inventors:

Henry Hon - Berkeley CA, US
Fred Cheng - Berkeley CA, US
Assignee:

Authenex, Inc. - Hayward CA
International Classification:

H04K 1/00
H04L 9/00
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.

US Patent:

7325728, Feb 5, 2008
Filed:

Mar 31, 2005
Appl. No.:

11/096985
Inventors:

Mandeep S. Arora - Danville CA, US
Fred Cheng - Aliso Viejo CA, US
Anant Agrawal - Diamond Bar CA, US
A. Louis Beaudoin - Oakland CA, US
Eric M. Chu - Laguna Niguel CA, US
Assignee:

Cantaloupe Systems, Inc. - Berkeley CA
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.

System And Method For Controlling Access To Multiple Public Networks And For Controlling Access To Multiple Private Networks

US Patent:

7334255, Feb 19, 2008
Filed:

Sep 29, 2003
Appl. No.:

10/675888
Inventors:

Paul Lin - Fremont CA, US
Henry Hon - Berkeley CA, US
Fred Cheng - Berkeley CA, US
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:

G07F 17/00
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.
