Methods and apparatuses for detecting tamper using heuristic models
The present application includes a computer-implemented method for detecting a tamper event. The method includes a step of receiving, from one or more sensors on an integrated module, data indicating one or more of light, acceleration, magnetic field, rotation, temperature, pressure, humidity, and audio. The method also includes a step of transmitting, to a microcontroller/evaluation engine coupled to the integrated module, the received data from the one or more sensors. The method further includes a step of determining, via the microcontroller, the received data exceeding one or more configurable thresholds of the tamper event. The method even further includes a step of assigning, via the microcontroller, a score associated with each of the one or more configurable thresholds being exceeded by the received data. The method yet even further includes a step of collecting, via the microcontroller, an aggregate total based on the assigning step. The method still further includes a step of evaluating, via the controller, the aggregate total in view of a predetermined alarm threshold of the tamper event.
