The identity of electrical devices is validated based on their consumption characteristics. A first characteristic of a device (101), corresponding to current electrical consumption characteristics associated with the device, is compared with a second characteristic of the device, corresponding to known electrical consumption characteristics associated with the device. The identity of the device is validated based on a result of the comparison. The device may have provided a preliminary identification previously, and the validation affirms this. The consumption characteristics may be measures by an ammeter (106a) and a voltmeter (106b). The characteristics may be consumption fingerprints, and may be produced using a function. The consumption characteristics may be determined using an electrical metric template, which may specify that the characteristics should be sampled over a period of time. The second characteristics may be obtained from a database. |
