Appl. No.:

11/562739

Inventors:

Paul Walters - Scottsdale AZ, US
Gregory Boardman - Laveen AZ, US
Robert D. Martin - Anthem AZ, US

Assignee:

Hypercom Corporation - Scottsdale AZ

International Classification:

G06K 15/00

US Classification:

235383, 235376, 714 57, 714712, 714716, 709251, 709246, 370397, 370401, 370223

Abstract:

The ‘IP Diagnostics’ software is a new and innovative method of aiding the deployment and troubleshooting of IP enabled POS terminals. Its purpose is to identify where a failure in the IP connection is occurring. The IP Diagnostics application does this by testing major failure points within the IP chain from the POS terminal to the host.

US Patent:

Filed:

May 1, 2008

Appl. No.:

12/113852

Inventors:

Norman S. Spiker - Phoenix AZ, US
Paul M. Walters - Scottsdale AZ, US

International Classification:

G06Q 40/00
H04L 9/10

US Classification:

705 70, 705 71, 705 73, 705 50

Abstract:

A method and apparatus is provided for secure terminals that facilitate secure data transmission and are compliant with the payment card industry (PCI) data security requirements. A security processor is combined with an application processor and a display into a secure display control unit (SDCU) that provides tamper resistance and other security measures. Modular secure I/O devices are interfaced to the SDCU via a wired, or wireless, medium so as to facilitate secure data transfer to the SDCU during a point-of-sale (POS) transaction or other transaction that requires secure data entry. The secure I/O devices implement one-time-pad (OTP) encryption, where the random keys, or pads, are generated by a derived unique key per transaction (DUKPT) generator. Other embodiments facilitate interconnection of the secure I/O devices to a hardware security module (HSM) or a personal computer (PC) while maintaining a high level of data security.

Appl. No.:

12/596127

Inventors:

Paul Walters - Scottsdale AZ, US
Ulf Andersson - Linkoping, SE

Assignee:

HYPERCOM CORPORATION - Scottsdale AZ

International Classification:

H04K 1/00
G06Q 20/00

US Classification:

705 67

Abstract:

This is for a payment device that may be constructed from separate modules in a secure fashion such that the aggregation of the modules constitutes an overall secure device without the use of additional covers, cases, or tamper-resistant housings. The methods and system are provided whereby the devices within a modular payment system can exchange data between each-other in a secure fashion. While data encryption is being used elsewhere, the present invention extends the security zone from each secure payment module within a modular device out over the cable to the next device. This allows the user to purchase payment device components, place them as they see fit, and not have to obtain certification on their end product as a POS-A level payment device.

Appl. No.:

13/176469

Inventors:

Paul Walters - Scottsdale AZ, US
Scott Spiker - Phoenix AZ, US

Assignee:

KEY INNOVATIONS LTD. - West Drayton

International Classification:

G06Q 20/00
H04L 9/32
H04N 7/167
G06F 21/00

US Classification:

705 73, 726 26, 726 16

Abstract:

A secure terminal, such as one used for point-of-sale debit card transactions, has a secure enclosure containing some or all of the terminal components, and is configured to send sensitive and non-sensitive data to a display located outside of the secure enclosure. The terminal includes a source chip that protects data sent from the terminal to the display. The source chip protects the data by detecting that the display is connected, authenticating the display as a device that is authorized to receive the data, and encrypting the data before transmission. Preferably, the display is a commercially-available consumer electronic device, such as a television or computer monitor. The source chip communicates with a receiver chip on the display to perform the detection, authentication, and encryption methods of the invention.
