1. A monitoring system, the monitoring system comprising:
- a monitor device attachable to a monitor target, wherein the monitor device includes;
a non-image based tamper detection circuit operable to detect tampering with the monitor device and to provide a first tamper indicator;
an image based tamper detection circuit operable to detect tampering with the monitor device based at least in part upon image comparison, and to provide a second tamper indicator, and wherein the image based tamper detection circuit forms an image of the size of a human bone around which the monitor device is attached; and
wherein the monitor device indicates a tamper occurrence when at least one of the first tamper indicator and the second tamper indicator indicate the occurrence of a tamper condition.

11. A method for device tamper detection, the method comprising:
-
providing a monitor device operable to identify a location of a monitor target, and including;
an image based tamper detection circuit, and a non-image based tamper detection circuit;determining whether the monitor device is attached to a monitor target using the non-image based tamper detection circuit to yield a first tamper indicator; capturing an initial image of the monitor target using the image based tamper detection circuit at a first time; capturing an update image of the monitor target using the image based tamper detection circuit at a second time, wherein the update image is an image of the size of a human bone around which the monitor device is attached; comparing the update image with the initial image to yield an image comparison result; and providing a second tamper indicator based upon the image comparison result; and indicating a tamper condition based at least in part on the combination of the first tamper indicator and the second tamper indicator. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
