Abstract
A tamper detection system for detecting tampering of an enclosure of an electronic device is provided. The tamper detection system includes a light source and a light sensor both mounted inside the enclosure and connected to a tamper detection circuit. The light sensor is spaced apart and separate from the light source. The light sensor is configured to sense light emitted by the light source, the light sensed by the light sensor having a characteristic. A characteristic of the sensed light is stored during an initialization phase. During normal operation, the tamper detection circuit is configured to turn the light source on and off on a predetermined time interval. Tampering of the enclosure is detected when the light sensed by the light sensor does not compare favorably to the stored characteristic. In another embodiment, a method for detecting tampering is provided.
