Embodiment Construction

[0024] Various embodiments will be described in detail with reference to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. References made to particular examples and implementations are for illustrative purposes, and are not intended to limit the scope of the invention or the claims.

[0025] The description of various embodiments refers to SIM cards, but the embodiments are equally applicable to equivalent memory cards and modules. The equivalent of the SIM in the Universal Mobile Telecommunications System (UMTS) is called the Universal Integrated Circuit Card (UICC), and the equivalent of the SIM in Code Division Multiple Access (CDMA) phones is the Removable Subscriber Identity Module (R- UIM). Also, as will be appreciated by those skilled in the art, the various embodiments are applicable to any form of smart card, including, for example, Secure Digital (SD) and flash memory c...

Abstract

A method and apparatus for controlling access to the data stored on a smart card for use in mobile devices. A user initializes the smart card memory by saving an authentication credential in memory. Subsequently, when various applications executed on the mobile device seek to retrieve the data stored in the smart card memory, the user must submit to an authentication process before access to the data stored in the smart card memory is granted. Embodiments utilize biometric traits and biometric templates stored in memory as authentication credentials. Biometric sensors are provided with the smart card so that a candidate biometric trait can be generated and compared with a biometric template stored in memory. If the biometric trait matches the stored biometric template, then access to the data stored in the smart card is granted.

Description

technical field [0001] The present invention relates to a system and method for securing mobile devices and data stored on smart cards used in mobile devices. Background technique [0002] A Subscriber Identity Module (SIM) card is a portable memory chip used in some models of cellular phones, especially GSM phones. The SIM maintains personally identifiable information, cell phone number, phonebook and text message data, and provisioning information that allows the cellular phone to make and receive calls on the cellular phone network (including ensuring that airtime is properly billed to the user's account). Because portable SIM cards contain personal and provisioning data, users of SIM card mobile devices can easily swap their cellular phone equipment with little service interruption. The user simply slides the SIM card out of the old cellular phone and into the new cellular phone. Once the SIM card is inserted into the new cellular phone, all necessary personal and prov...
