Abstract: A computer-implemented system and method for device discovery and recovery in a secure network comprises registering a plurality of devices, where the devices form the secure network at a location. Communication between the plurality of registered devices is enabled, and messages passed between the plurality of devices are collected. The method further comprises determining which one of the plurality of devices is a compromised device by using a consensus network that includes the plurality of devices of the secure network.

Abstract: In an approach for selecting a battery charging rate, a processor, responsive to an electronic device with a rechargeable battery being connected to a battery charging device, identifies a current battery status of the rechargeable battery. A processor determines a disconnect time of the battery charging device. A processor determines a charge level required. A processor determines a charging profile based on the current battery status, the disconnect time of battery charging device, and the charge level required. A processor sends the charging profile to the battery charging device.

Abstract: A computer-implemented method, a computer program product for predictive device maintenance, and system for a plurality of Internet of Things (IoT) devices. One embodiment may comprise generating a risk score as a weighted measure of input data about an Internet of Things (IoT) device and a frequency of failure of the IoT device, determining an optimal time to trigger a predictive notification pertaining to the IoT device using the risk score, and at the determined optimal time, issuing the predictive notification. The risk score in some embodiments may indicate an estimate of loss of function of the IoT device.
