Abstract: A network node is configured to enable authentication of a user of a client device based on biometric data captured by the client device. The network node receives, from the client device, a request to authenticate a user that includes a first set of transformed biometric data transformed with a first secret feature transform key shared with the client device; fetches, from a secure end-user repository, a second set of enrolled transformed biometric data associated with the first set of transformed biometric data and a second secret feature transform key with which the second set of biometric data was transformed at enrolment of the transformed biometric data; and submits the second set of transformed biometric data and the second secret feature transform key over a secure communication channel to the client device.

Abstract: The present disclosure relates to methods and devices for fingerprint recognition. In an aspect, a method of a fingerprint sensing system of extracting at least one fingerprint descriptor from an image captured by a fingerprint sensor for enrolment in the fingerprint sensing system is provided. The method comprises capturing images of a finger contacting the fingerprint sensor, detecting at least one fingerprint feature in each captured image, extracting fingerprint data from an area surrounding a location of the detected feature in each captured image, and extracting a fingerprint descriptor by performing a transform of the fingerprint data extracted from the area surrounding the location of the detected feature in each captured image, wherein a size of the area is selected such that the area comprises sufficient information to allow a duplicated descriptor to be discarded for the captured images.

Abstract: An acoustic biometric imaging system for acquiring a fingerprint representation, comprising: a device member; a transmitter transducer having a first fundamental mode resonance frequency, coupled to the device member; drive circuitry; a receiver transducer having a second fundamental mode resonance frequency, coupled to the device member; receiver circuitry; and processing circuitry configured to: control the drive circuitry to provide an electrical excitation signal to the transmit transducer resulting in fundamental mode oscillation of the transmit transducer with a frequency spectrum having a peak frequency being higher than the first fundamental mode resonance frequency and the second fundamental mode resonance frequency; receive, from the receiver circuitry, an electrical sensing signal indicative of an acoustic reflection signal; and determine the fingerprint representation based on the sensing signal received from the receiver circuitry.

Abstract: Mechanisms for requesting, by a client device, registration of identified data at a sensor reader. A request command is sent from the client device and to the sensor reader pertaining to a registration operation to be performed on identified data at the sensor reader. A security policy is assigned to the identified data by the sensor reader. A first security protected object and a second security protected object of the identified data are created by the sensor reader and based on the request command and the security policy. The second security protected object is sent, by the sensor reader, to the client device. The first security protected object is sent, by the sensor reader, towards the trusted server. The trusted server, upon reception of the first security protected object, verifies that the sensor reader that created the first security protected object has a security trusted relationship with the trusted server.

Abstract: Methods and devices for updating biometric template protection keys can include updating at least one stored feature transformation key with which a set of biometric data of a user initially has been transformed at a first client device at which the biometric data of the user was captured and enrolled with a network node, which set of transformed biometric data of the user is stored at a biometric data verification node that does not have access to the feature transformation key. The method comprises generating random data, computing at least one new feature transformation key based on said random data, replacing the at least one stored feature transformation key with the computed at least one new feature transformation key, and transmitting the generated random data to the biometric data verification node, which uses the generated random data to update the at least one set of transformed biometric data.
