  • Patent number: 12212819
    Abstract: A device receives a video stream, where one or more frames of the video stream include embedded metadata that is embedded directly into the one or more frames. The device extracts the embedded metadata from the one or more frames. The device makes an authentication determination regarding the video stream, based on whether the embedded metadata includes a digital signature associated with a sender of the video stream. The device controls, based on the authentication determination, presentation of the video stream to a recipient user.

  • Patent number: 11689666
    Abstract: In one embodiment, a device obtains audio data from one or more past conferences. A prediction model that predicts when participants of a conference will speak is generated based on the audio data from the one or more past conferences. The device uses the prediction model to predict a speech distribution for participants of a particular conference. Then, the device proactively optimizes audio parameters of the particular conference based on its predicted speech distribution.

  • Patent number: 11595283
    Abstract: In one embodiment, a device maintains a buffer of historical telemetry data of a particular type of telemetry. The device obtains new telemetry data of the particular type of telemetry. The device makes a state evaluation by comparing the new telemetry data to the buffer, to determine whether the new telemetry data is an outlier. The device sends a message indicative of the new telemetry data to a message bus for delivery to a recipient that is not subscribed to receive telemetry data of the particular type of telemetry, when the device determines that the new telemetry data is an outlier.

  • Publication number: 20230023723
    Abstract: In one embodiment, a device inserts a watcher module between a first module and a second module in a low-code workflow. The device intercepts, via the watcher module, output data being passed by the first module to the second module. The device determines whether the output data represents a policy violation. The device blocks, via the watcher module, the output data from being input to the second module, when the output data represents a policy violation.

  • Publication number: 20220414348
    Abstract: In one embodiment, a device determines a comprehension level for a portion of text associated with an online conversation, based in part on a topic of the portion of text. The device makes a comparison between the comprehension level for the portion of text with a comprehension level of a participant of the online conversation. The device generates adjusted text based on the portion of text, wherein the adjusted text has a comprehension level that is equal to or lower than that of the participant. The device provides the adjusted text for display to the participant.
