Supply current monitoring for anomaly detection on IoT devices
Επιτομή
This paper presents results from the correlation of the supply current of a smart device to its functional characteristics in order to detect a manufacturing or an operational anomaly. Awareness of the typical operation of a smart device in terms of operation and functionality, may prove valuable, since any deviation may warn for operational or functional anomaly. This is a symptomatic approach rather than an analytical approach of the cause. In this paper, the deviation (either increase or decrease) of the supply current is exploited for this reason. The paper offers the results from an IP camera case study that proves this assumption. c 2017 Association for Computing Machinery.
