  • Publication number: 20220122375
    Abstract: Biometric recognition systems and methods are described, including a biometric recognition system including a user system with a biometric able to scan a finger and provide an image. From the image, a plurality of features may be extracted to create at least one fingerprint feature vector using a convolutional neural network.

  • Patent number: 10992664
    Abstract: A fingerprint identification system comprising a smart device, a fingerprint scanner, a processor coupled to a transceiver and to the fingerprint scanner, and a digital storage element coupled to the processor. The digital storage element stores logic that causes the processor to: activate the fingerprint scanner to scan a user's finger, identify a feature and multiple minutia of the user's fingerprint, and generate a digital fingerprint string(s) indicative of a position of each minutia relative to the feature. The processor is then caused to combine the digital fingerprint string(s) with a first cryptographic salt to generate a first hash. The first hash is compared to a first hash signature to determine if the first hash represents an authentic fingerprint. If authentic, the processor combines the digital fingerprint string(s) with a second cryptographic salt to generate a second hash. This second hash is transmitted to one or more servers.

  • Publication number: 20150324789
    Abstract: The present disclosure describes a method in which an encrypted request to transfer a requested amount of cryptocurrency from a user address to a destination address is received. The request includes a destination address, a requested amount, a user device encryption key, and biometric data. A partially signed transaction to transfer a requested amount of cryptocurrency from the user address to the destination address is also received. The partially signed transaction is cryptographically signed and a multi-signed transaction is broadcast to a cryptocurrency network to transfer the requested amount of cryptocurrency from the user address to the destination address.

  • Patent number: 4906180
    Abstract: A gas fired infrared burner ceramic tile retainer for securing ceramic burner tiles within a plenum including a one-piece cut-and-form stamped tile retainer made of continuous sheet metal includes a top portion which is substantially horizontal for engaging the burner tile edge and a transverse portion which is substantially perpendicular to the top portion which includes a plurality of tabs extending downwardly from the transverse portions. These tabs are placed at intervals around the bottom of the tile retainer and are adapted to be bent under the plenum which contains the burner tile. The plenum has a tile receiving lip around its upper outer perimeter, and the tabs are bent underneath this lip to secure the burner tile by sandwiching the outer edges of the burner tile between the tile retainer and the plenum tile receiving lip. The disclosed tile retainer furthermore helps to maintain a substantially gas tight seal between the ceramic tile and the plenum.
