Definition

Tamper detection is the ability of a device to sense that an active attempt to compromise the device integrity or the data associated with the device is in progress; the detection of the threat may enable the device to initiate appropriate defensive actions.

Theory and Applications

The tamper detection design can be implemented to sense different types, techniques, and sophistication of tampering, depending on the perceived threats and risks.

The methods used for tamper detection are typically designed as a suite of sensors each specialized on a single threat type, some of which may be physical penetration, hot or cold temperature extremes, input voltage variations, input frequency variations, x-rays, and gamma rays.

Examples of techniques used to detect tampering may include any or all of the following: switches to detect the opening of doors or access covers, sensors to detect changes in light or pressure...
