    Abstract: Embodiments of the present disclosure provide a method and a device for cross-domain strong logically isolation and secure access control in the Internet of Things (IoT). The method includes the following. When one IoT gateway receives the identity authentication request, the IoT gateway sends the identity authentication request to all IoT gateways in the domain excluding that IoT gateway. When all IoT gateways in the domain receive the identity authentication request, all IoT gateways verify separately whether the identity authentication request is legal. After a certain IoT gateway obtains the identity authentication result, a distributed consensus procedure is initiated. The IoT gateways in the domain reach a consensus on the identity authentication result through a distributed consensus mechanism, and the identity authentication result is written and stored to a block of a blockchain.

  • Publication number: 20220398635
    Abstract: A preliminary software feature is applied in a testing rollout to a discrete subset of customers. Survey data may be collected from those customers through a variety of sources, such as chatbot text, session workflow, historical user data, social media data, email survey data, user profile data, messaging threads, and the like. This survey data is analyzed using machine learning algorithms to derive the meaning of input text as well as to determine the user sentiment expressed therein. The outputs of this analysis are normalized across sources and aggregated at a feature-level to generate overall metrics of customer satisfaction with the feature. A holistic analysis is performed on this customer sentiment data to obtain an aggregate or combined user satisfaction score. This score is applied against a set of guardrails to determine whether to ship the feature to a broader customer base.
