  • Patent number: 11757966
    Abstract: A first segment of a probe media item that is transmitted as a first live-stream of an event is received. After a first delay period, whether the first segment of the probe media item is similar to a first segment of a first reference media item that is transmitted as a second live-stream of the event and received subsequent to the probe media item is determined. Responsive to determining, after the first delay period, that the first segment is similar to the first segment of the first reference media item, a remedial action in association with the probe media item is performed.

  • Publication number: 20230179409
    Abstract: Embodiments of the invention relate to a computer-implemented method for generating verification keys of a public-key signature scheme in a distributed network. The method comprises performing, by a subset of the nodes of a first subnetwork of nodes, a first distributed key generation protocol, the first distributed key generation protocol being configured to generate jointly a verification key for the first subnetwork and a plurality of corresponding secret key shares for the nodes of the first subnetwork. The method further comprises a step of performing, for a second subnetwork, by a subset of the plurality of nodes of the first subnetwork, a second distributed key generation protocol, the second distributed key generation protocol being configured to generate jointly a verification key of the second subnetwork and a plurality of corresponding secret key shares for the nodes of the second subnetwork.

  • Publication number: 20220377133
    Abstract: According to an embodiment of a first aspect of the invention, there is provided a distributed network comprising a plurality of nodes. Each of the plurality of nodes is configured to run one or more computational units comprising its own unit state. The network is configured to individually execute, by an execution subset of the plurality of nodes, s set of execution messages in a deterministic manner, thereby mutating the unit states of one or more of the computational units of the execution subset. The network is further configured to regularly make, by the nodes of the execution subset, a read snapshot of the unit states of the one or more computational units of the execution subset and to provide, by one or more nodes of the execution subset, user access to the read snapshot. Further aspects of the invention relate to a corresponding computer-implemented method, a node, a computer program product and a software architecture.

  • Publication number: 20220121975
    Abstract: Implementations disclose methods and systems for using Bayesian inference to predict review decisions in a match graph. A method includes identifying a current media item to be processed; processing labeled media items to identify labeled media items that include at least one respective segment that is similar to one of segments of the current media item; for each of the segments of the current media item, generating a segment prediction value indicating a particular property associated with a corresponding segment of the current media item based on properties associated with respective labeled media items that each include a respective segment similar to the corresponding segment; calculating a media item prediction value for the current media item based on a generated segment prediction value of each of the segments of the current media item; and causing the current media item to be processed based on the calculated media item prediction value.

  • Patent number: 10659509
    Abstract: A system and method includes receiving a first segment of a probe media item that is transmitted as a first live-stream of an event. The method includes determining, after a first delay period, whether the first segment of the probe media item is similar to a first segment of a first reference media item that is transmitted as a second live-stream of the event and received subsequent to the probe media item. The method includes determining, after the first delay period, whether a second segment of the probe media item is similar to a second segment of the first reference media item. The method also includes responsive to determining that the first segment and the second segment of the probe media item are respectively similar to the first segment and the second segment of the first reference media item, performing a remedial action in association with the probe media item.
