Abstract
A device can be identified using a manufacturing characteristic in the device. Power consumption data associated with a device is received. A power model can be fitted to the power consumption data and at least one parameter is determined based on fitting. A fingerprint of the device can be created based on at least one parameter.
Claims20
A method comprising:
- receiving power consumption data associated with a device;
- fitting a power model to the power consumption data and determining at least one parameter based on the fitting;
- and
- creating a fingerprint of the device based on the at least one parameter.
1 more element
A system, comprising:
- at least one hardware processor coupled with a memory device, the at least one hardware processor operable to at least:
- receive power consumption data associated with a device, wherein a manufacturing characteristic of the device contributes to power consumption specified in the power consumption data;
- fit a power model to the power consumption data and determine at least one parameter based on fitting the power model;
- and
- create a fingerprint of the device based on the at least one parameter.
2 more elements
A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:
- receive, by the computer, a communication from a device;
- monitor, by the computer, power consumption of the device;
