  • Patent number: 11568878
    Abstract: Techniques disclosed herein are directed towards streaming keyphrase detection which can be customized to detect one or more particular keyphrases, without requiring retraining of any model(s) for those particular keyphrase(s). Many implementations include processing audio data using a speaker separation model to generate separated audio data which isolates an utterance spoken by a human speaker from one or more additional sounds not spoken by the human speaker, and processing the separated audio data using a text independent speaker identification model to determine whether a verified and/or registered user spoke a spoken utterance captured in the audio data. Various implementations include processing the audio data and/or the separated audio data using an automatic speech recognition model to generate a text representation of the utterance.

  • Patent number: 11569998
    Abstract: A system and method are provided for generating access tokens on a user device rather than via a remote server computer. An access token can be generated on a second user device by combining and encrypting, with format preservation, a primary access identifier, variable value, and salt. The resulting value can be provided to a first user device that can subsequently can provide the access token to an access device as part of an interaction. The access device can generate an authorization request message that comprises the access token and transmit it to a remote server computer for processing. The remote server computer can process the access token to determine the primary access identifier despite not being involved in the generation of the access token, providing an improvement over conventional tokenization methods.

  • Patent number: 11558741
    Abstract: A method is disclosed. The method includes receiving a broadcast signal from a beacon device, the broadcast signal encoding a first credential associated with a first entity. In response to receipt of the broadcast signal, the mobile communication device transmits the received first credential to an authentication system. The authentication system determines if the first entity associated with the broadcast signal is authentic and generates a confirmation message confirming the authenticity of the first entity. The mobile communication device then receives the confirmation message indicating that the first entity is authentic. The mobile communication thereafter receives and transmits a second credential for the mobile communication device to the beacon device, which transmits the second credential to the authentication system. The authentication system then confirms the authenticity of the mobile communication device.

  • Publication number: 20220417231
    Abstract: Embodiments of the invention are directed assessing reliability between two computing devices. A distributed database may maintain reliability associations between pairs of computing devices. Each reliability association may indicate a particular device has determined (e.g., locally) that another device is reliable. In order to determine an amount of reliability between a first computing device and a second computing device, an ordered combination of the reliability associations may be determined utilizing the distributed database. The ordered combination of reliability associations may identify a reliability path between the first computing device and the second computing device. An amount of reliability may be determined based on the reliability path. An interaction between the devices may be allowed or restricted based at least in part on the amount of reliability between the computing devices.

  • Publication number: 20220405262
    Abstract: Anchor tree cross-merge within a distributed storage system. A computer system identifies a data structure that includes (i) a root anchor tree and (ii) an ordered set of anchor trees that are ordered based on their creation, such that a last anchor tree of the ordered set of anchor trees is most-recently created. The data structure stores index data for a set of objects stored in a non-volatile storage. The computer system creates a new anchor tree in the ordered set of anchor trees. The computer system identifies, from a set of delta tables, index data representing one or more objects that are stored on the non-volatile storage. The computer system merges the index data representing the one or more objects into the new anchor tree.
