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.

Appl. No.:

12/948705
Inventors:

Fred Cheng - Los Altos Hills CA, US
International Classification:

H04L 9/32
US Classification:

726 9
Abstract:

The present disclosure proposes a secure way to generate the OTP code by way of a web browser. A user does not need any electronic device on hand to obtain OTP for 2FA login. A new Rubbing Encryption Algorithm (REAL) is proposed as the base technology. Implementation method of such web-based OTP token is presented and analyzed. It operates through a web-browser with a multiple REAL keys. It can be integrated into many secure Internet commerce applications as well. A system is provided for secure access to a software program or website. The system has a first entity with a computing device with a processor and a memory. The first entity provides a plurality of data items. The system also has a second entity with at least one display for displaying the plurality of data items. The data items are arranged in a predetermined format. The display also displays a prompt for a user identification and a prompt for a code. The second entity has a member with a transparent portion. The transparent portion comprises a periphery with a plurality of markings placed around the periphery. The markings point to a first direction or to an opposite second direction. The second entity overlays the member over the data items. The markings point to the plurality of data items to reveal a code. The code is input and permits access of the second entity to the computing device of the first entity.
