Abstract: Certain aspects of the present disclosure provide techniques and apparatus for biometric authentication using an anti-spoofing protection model refined using online data. The method generally includes receiving a biometric data input for a user. Features for the received biometric data input are extracted through a first machine learning model. It is determined, using the extracted features for the received biometric data input and a second machine learning model, whether the received biometric data input for the user is authentic or inauthentic. It is determined whether to add the extracted features for the received biometric data input, labeled with an indication of whether the received biometric data input is authentic or inauthentic, to a finetuning data set. The second machine learning model is adjusted based on the finetuning data set.

Abstract: In some implementations, a global navigation satellite system (GNSS) device may determine its approximate location, and, for each pseudorange measurement of a plurality of pseudorange measurements performed by the GNSS device: determine a location of a respective satellite vehicle (SV) that transmits a respective GNSS signal of which the pseudorange measurement is performed, and determine a respective residual grid, where the respective residual grid is based on respective information from the pseudorange measurement and the location of the respective SV, and the respective residual grid is indicative of possible locations of the GNSS device within a geographical region including the approximate location of the GNSS device. The GNSS device may aggregate the residual grids corresponding to at least a portion of the plurality of pseudorange measurements and may determine a location estimate of the GNSS device based on the aggregation of the residual grids.

Abstract: A method of determining a position of a device includes obtaining an initial position of the device without using Global Navigation Satellite System (GNSS) satellites. GNSS measurements are taken of radio frequency (RF) signals transmitted by the GNSS satellites. Initial residuals are determined based, at least in part, on GNSS measured distances determined from the at least a portion of the GNSS measurements and expected distances determined from the initial position. Errors of the GNSS measurements based on the RF signals are estimated. An optimization is performed using some of the estimated errors to produce a modified set of residuals, wherein the optimization is further based on H, wherein H represents a matrix with trigonometric functions of a geometry of the GNSS satellites. A cost minimization method of the modified set of residuals and actual geometry of the GNSS satellites (H) to determine an improved position of the device.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for biometric authentication using neural-network-based anti-spoofing protection mechanisms. An example method generally includes receiving an image of a biometric data source for a user; extracting, through a first artificial neural network, features for at least the received image; combining the extracted features for the at least the received image and a combined feature representation of a plurality of enrollment biometric data source images; determining, using the combined extracted features for the at least the received image and the combined feature representation as input into a second artificial neural network, whether the received image of the biometric data source for the user is from a real biometric data source or a copy of the real biometric data source; and taking one or more actions to allow or deny the user access to a protected resource based on the determination.

Abstract: A method of entering a facial image of an individual into a database of recognised and authorised individuals, the method comprising the steps of: receiving, from an image capture device connected to a database processing device, an image of a scene; determining whether the image of the scene contains a facial image of a recognised and authorised first individual; determining whether the image of the scene contains a facial image of a second individual and, if the image of the scene contains a facial image of a second individual, determine if the second individual is a recognised and authorised individual; if the second individual is not a recognised and authorised individual, determine whether the image of the scene includes a security gesture by the recognised and authorised first individual; and entering the facial image of the second individual to the database of recognised and authorised individuals if the image of the scene includes the security gesture by the recognised and authorised first individual.

Abstract: The invention relates to a method, system and apparatus to allow the collection of data relating to at least one parameter of an item of currency and which data can be used to generate a new or updated dataset for the same and which can be used by validation apparatus for said items of currency. The collected data is transmitted from a location which is remote from that at which the new data set is generated and the new dataset is transmitted to the said remote location and/or other locations so as to allow the new or updated dataset to be used by the apparatus.

Abstract: A method for incorporating a set of requirements into an executable program to be run on an airborne system is provided. The method obtains the set of requirements for the program in a first format. The method uses a first tool to convert the set of requirements in the first format into a second format utilizing a markup language. The method uses a second tool to convert the set of requirements in the second format into a third format that influences a behavior of the program without changing the program. The method uses a third tool to determine whether the set of requirements in the third format incorporates all of the set of requirements in the second format in order to verify the program under a compliance standard for the airborne system without performing a verification process directly on the program.
