  • Publication number: 20210216885
    Abstract: A method, apparatus, device, and storage medium for expanding data are disclosed. The method includes: acquiring a triplet from a knowledge graph; mining a relationship path equivalent to a relationship in the triplet from the knowledge graph, a subject in the triplet being used as a start point of the relationship path, and an object in the triplet being used as an end point of the relationship path; and expanding the triplet based on the relationship path to generate an expanded triplet. This implementation expands the triplet in the knowledge graph, and strengthens the association between the subject and the object in the triplet in a larger context, such that the association between the subject and the object in the triplet is more global.

  • Patent number: 11044318
    Abstract: A first request is received from a first processing node to produce data blocks of a first data stream representing a first communication topic. The first processing node is one of the processing nodes handling a specific function. Each of the processing nodes is executed within a specific node container having a specific operating environment. A global memory segment is allocated from a global memory to store the data blocks of the first data stream. A first local memory segment is mapped to the global memory segment. The first local memory segment is allocated from a first local memory of a first node container containing the first processing node. The first processing node directly accesses the data blocks of the first data stream stored in the global memory segment by accessing the mapped first local memory segment within the first node container.

  • Patent number: 11031017
    Abstract: A method includes receiving an utterance of speech and segmenting the utterance of speech into a plurality of segments. For each segment of the utterance of speech, the method also includes extracting a speaker-discriminative embedding from the segment and predicting a probability distribution over possible speakers for the segment using a probabilistic generative model configured to receive the extracted speaker-discriminative embedding as a feature input. The probabilistic generative model trained on a corpus of training speech utterances each segmented into a plurality of training segments. Each training segment including a corresponding speaker-discriminative embedding and a corresponding speaker label. The method also includes assigning a speaker label to each segment of the utterance of speech based on the probability distribution over possible speakers for the corresponding segment.

  • Publication number: 20210167962
    Abstract: A trust token may be created including authentication data for a user and his or her associated communication device. The trust token may be transmitted by the communication device to one or more recipients, such as a token server. The recipients may interpret the trust token and verify it against data written to one or more nodes of a blockchain when the user and the communication device registered for the trust token. Once the trust token is verified, the token server may be configured to generate, maintain, and provision account tokens representing sensitive data. The token server may push one or multiple account tokens to the communication device, thereby allowing the communication device to perform transactions with the account tokens. In other words, the implementation of a trust token may allow the communication device to be provisioned with multiple account tokens, without requiring multiple logins or transmissions of sensitive data.

  • Patent number: 11017784
    Abstract: Methods, systems, apparatus, including computer programs encoded on computer storage medium, to facilitate language independent-speaker verification. In one aspect, a method includes actions of receiving, by a user device, audio data representing an utterance of a user. Other actions may include providing, to a neural network stored on the user device, input data derived from the audio data and a language identifier. The neural network may be trained using speech data representing speech in different languages or dialects. The method may include additional actions of generating, based on output of the neural network, a speaker representation and determining, based on the speaker representation and a second representation, that the utterance is an utterance of the user. The method may provide the user with access to the user device based on determining that the utterance is an utterance of the user.

  • Publication number: 20210152365
    Abstract: A blockchain system for ownership verification may include one or more issuer network nodes and one or more verification network nodes. An issuer network node may be configured to receive a request including a public key to issue a credential, provision the credential to the communication device, generate a payload derived from hashing the credential and the public key, store the payload in a record of a blockchain, and synchronize the record to other network nodes on the blockchain. A verification network node may be configured to receive the credential, the public key, and a signature generated by the communication device to request access to a resource, verify the signature using the public key, generate a hash value based on the credential and the public key, determine that the hash value is stored in the blockchain, and authenticate the communication device for access to the requested resource.

  • Publication number: 20210152366
    Abstract: Embodiments of the invention enable a distributed ledger system including a network of entities that maintain an electronic ledger that can keep track of information related to events performed by various entities in the network. An operating entity may manage access to the distributed ledger system and may allow certain authorities and users to onboard with the distributed ledger system. A user device may generate a request to include data in the electronic ledger. The user device may generate a cryptogram and send the cryptogram with the request to a reader device, which may initiate a verification process to verify the cryptogram. If the cryptogram is verified, the data from the user device may be sent to one or more authorities so that it can be included in the electronic ledger.

  • Publication number: 20210126939
    Abstract: Systems, methods, and devices are disclosed for preventing relay attacks. A user device may receive (e.g., when proximate to the first access device), from an intervening device, device identification data for a first access device. A message may be received from a second access device via the intervening device. The message may include a digital signature generated based at least in part on second access device identification data. The user device may validate the message utilizing the digital signature and a public key. If the message is invalid, the user device may discard the message. If the message is valid, (e.g., unaltered), the user device may determine that the user has not confirmed an intent to interact with the second access device and may terminate an further interaction with the second access device accordingly.
