Title:
METHODS AND APPARATUS TO IDENTIFY ABNORMAL BEHAVIOR WITHIN SETS OF INTERNET-OF-THINGS DEVICES
Document Type and Number:
WIPO Patent Application WO/2021/120010
Kind Code:
A1
Abstract:
Methods and apparatus automatically identify which Internet-of-Things (IoT) devices within a set are behaving in a manner non-compliant to a target behaviour. Each IoT device (11) is assigned to a grid point in a notional m-dimensional space. A respective assessment module (2, 3) is arranged to monitor behaviour of a group of IoT devices assigned to grid points that are aligned with one another at a respective position along the respective dimension, and to produce an output indicative of non-compliant behaviour in the event that the monitoring indicates that behaviour in the group of IoT devices deviates from a behavioural model of the IoT devices of said group. An identification module (5) identifies at least one non-compliant IoT device in the set of IoT devices by combining outputs from the assessment modules assigned to the different dimensions of the space. The assessment modules may use trained machine-learning algorithms embodying a model of normal behaviour of the group of devices.
