  • Patent number: 10839091
    Abstract: Machine logic (for example, software) for protecting sensitive and confidential user data and sending the protected user data to an authorized third party for predictive analytics purposes. The machine logic rules perform linear transformation operations on the sensitive and confidential user data in order to obscure the underlying data before it is sent to an authorized third party for performing predictive analysis of the underlying data. After performing predictive analysis on the obscured data by the authorized third party, the owner of the sensitive and confidential data takes a consequential action (that is, the owner of the data makes a business-related decision) based on the prediction.

  • Publication number: 20200344838
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may run a process associated with a low latency. As such, the UE may operate in a mode to stay in a connected state with a network. The mode may include transmitting a keep alive message. Such message may be transmitted based in part on a keep alive timer with a shorter duration than a network traffic inactivity timer. If no communications occur between the UE and the network by the expiration of the keep alive timer, the UE may transmit a keep alive message to the network to maintain the connected state and reset the keep alive timer. Alternatively, if communications do occur, the UE may reset the keep alive timer. If the process is terminated, the UE may exit the mode for staying in the connected state, which may include canceling the keep alive timer.
