Filed:

Oct 3, 2005

Appl. No.:

11/243008

Inventors:

Bruce Lyle Moullette - Modesto CA, US
Mohammad A. Khan - San Jose CA, US
Jorge M. Fernandes - Los Altos Hills CA, US
Ahmer Ali Khan - La Jolla CA, US
Anna C. Stockel - San Jose CA, US

Assignee:

VIVOtech, Inc. - Santa Clara CA

International Classification:

G06K 7/08

US Classification:

235449

Abstract:

An adaptor in accordance with the present invention allows a conventional magnetic stripe card POS reader to receive information from contact-based or wireless sources while maintaining the concurrent ability of the reader to interact with a magnetic stripe card. In accordance with one embodiment of the present invention, the adaptor includes an inductor capable of generating a magnetic field of sufficient power to couple with a head of a magnetic stripe card reader through the housing of the reader device. In this manner, the adaptor can be positioned external to the reader device, leaving the slot of the reader accessible for conventional interactions with magnetic stripe cards. Selective inductive communication with individual heads of the reader device may exploit their differing sensitivity to external magnetic fields generated by the adaptor.

Ahmer A. Khan - Milpitas CA, US

Assignee:

Apple Inc. - Cupertino CA

International Classification:

H04L 9/32

US Classification:

713168

Abstract:

Disclosed herein are systems, methods, and non-transitory computer-readable storage media for key management for Issuer Security Domain (ISD) using GlobalPlatform Specifications. A client receives from a server an authorization to update a first ISD keyset. The client encrypts, via a client-side secure element, a second ISD keyset with a server public key. The client sends the encrypted second ISD keyset to the server for updating the first ISD keyset with the encrypted second ISD keyset. Prior to updating, the client generates the first ISD keyset at a vendor and sends the first ISD keyset to the client-side secure element and sends the first ISD keyset encrypted with the server public key to the server. The disclosed method allows for updating of an ISD keyset of which only the client-side secure element and a server have knowledge.

International Classification:

G06Q 20/04
G06Q 20/32
G06Q 20/38

Abstract:

To facilitate conducting a financial transaction via wireless communication between an electronic device and another electronic device, the electronic device determines a unique transaction identifier for the financial transaction based on financial-account information communicated to the other electronic device. The financial-account information specifies a financial account that is used to pay for the financial transaction. Moreover, the unique transaction identifier may be capable of being independently computed by one or more other entities associated with the financial transaction (such as a counterparty in the financial transaction or a payment network that processes payment for the financial transaction) based on the financial-account information communicated by the portable electronic device. The electronic device may also associate receipt information, which is subsequently received from a third party (such as the payment network), with the financial transaction by comparing the determined unique transaction identifier to the computed unique transaction identifier.

H04L 9/30

Abstract:

Techniques are disclosed relating to authenticating a user with a mobile device. In various embodiments, a mobile device receives a request to provision the mobile device with identification information from an identification document issued by an authority to a user for establishing an identity of the user. In response to the received request, the mobile device issues a request for verification information signed by the authority and usable to verify the identification information. The issued request identifies multiple public keys of the mobile device, each having a respective corresponding private key for generating a signature usable to verify the identification information. The mobile device receives and stores the signed verification information, the signed verification information including the plurality of public keys. In some embodiments, the mobile device receives a request provide, at least, a portion of the identification information and selects one of the private keys to generate a signature.
