Abstract: A method for assisting a user of a fingerprint sensing system includes sensing a position of a user's finger relative to a swiped fingerprint image sensor, and providing to the user, in response to the sensed finger position, an indication of finger placement relative to the fingerprint image sensor. The indication of finger placement may include a display on a computer monitor of actual finger placement and desired finger placement. The fingerprint sensing system may include an image sensor to sense a fingerprint on a swiped finger, a finger position sensor to sense the position of the finger relative to the image sensor, and processing apparatus to provide the indication of finger placement to the user.

Abstract: An apparatus is disclosed in a first embodiment of the invention as including a non-conductive substrate providing a first surface onto which a user can apply a fingerprint. A fingerprint sensing circuit is applied to a second surface of the non-conductive substrate opposite the first surface. The fingerprint sensing circuit is capable of sensing a fingerprint through the non-conductive substrate. A navigation device is positioned adjacent to (e.g., below) the non-conductive substrate and is capable of being manipulated by the user through the non-conductive substrate.

Abstract: A fingerprint sensing circuit for reducing noise and parasitic capacitive coupling is disclosed in one embodiment of the invention as including a plurality of transmitting elements to sequentially emit a probing signal. A digital ground is provided to ground digital components in the fingerprint sensing circuit. A quiet ground, separate from and quieter than the digital ground, is provided to ground transmitting elements that are not transmitting the probing signal. Similarly, control logic is provided to connect, to the quiet ground, transmitting elements that are not transmitting the probing signal, while disconnecting, from the quiet ground, transmitting elements that are emitting the probing signal. The quiet ground helps to reduce the adverse effects of parasitic capacitive coupling and noise on the inactive transmitting elements.

Abstract: A user transaction request is received at a client device. A web browser plug-in communicates the user transaction request to a server that determines whether the user transaction request is a secure transaction. Transaction data is received from the server via the web browser plug-in. If the received transaction data indicates a secure transaction, the user is prompted to provide biometric data from a user using a biometric device and related security protocols. The web browser plug-in then communicates a transaction confirmation to the server.

The fingerprint sensing circuit is configured to drive the fingerprint sensing elements according to the designated pattern. In selected embodiments, the fingerprint sensing elements may include transmitting elements, receiving elements, or a combination thereof.

Abstract: Biometric information is authenticated by a web-enabled application that identifies a biometric sensor installed in a client device. The authentication procedure reads biometric information associated with a user and compares the biometric information with a biometric template associated with that user. If the biometric information matches the biometric template, the authentication procedure retrieves credentials associated with the user and communicates those credentials to a requesting process.

Abstract: A user request to implement a secure transaction is received and communicated to a web server. Transaction details signed with a secret key are received from the web server and displayed to the user. The user is requested to confirm the secure transaction by providing biometric data. If the user's biometric data is validated, an authentication token is received from a biometric device and the authentication token is communicated to the web server. The web server processes the secure transaction if the authentication token is confirmed as a valid authentication token.

Abstract: A request for a secure financial transaction is received from a user, who is authenticated with a biometric device. If the user is authenticated, an authentication token is received from the biometric device and sent to a remote device, which initiates the secure financial transaction. Upon initiation of the secure financial transaction, details related to the secure financial transaction are displayed to the user and the those details are monitored until the secure financial transaction is completed.

Abstract: A transaction request containing transaction details from a requesting device is generated by a web-enabled application executing on the requesting device. A secure signature associated with the transaction details is calculated using a secret key. The transaction details and the secure signature associated with the transaction details are communicated to the requesting device. Confirmation information is received from the requesting device and validated. If the confirmation information is valid, the requested transaction is implemented.

Abstract: A system for securing an integrated circuit chip used for biometric sensors, or other electronic devices, by utilizing a physically unclonable function (PUF) circuit. These PUF functions are in turn used to generate security words and keys, such as an RSA public or private key. Such a system can be used to protect biometric security sensors and IC chips, such as fingerprint sensors and sensor driver chips, from attack or spoofing. The system may also be used in an efficient method to produce unique device set-up or power-up authentication security keys. These keys can be generated on a low frequency basis, and then frequently reused for later security verification purposes. In operation, the stored keys can be used to efficiently authenticate the device without the need to frequently run burdensome security key generation processes each time, while maintaining good device security.
