Abstract: An anti-tamper system comprises: a fixing device (500) and an anti-tamper detection device (502); said fixing device (500) comprising a body (514) and a head (512) whereby the head (512) having a larger cross section than the body (514) for enabling a tool to engage and drive the body (514) into a first material layer (22) thereby makes a firm connection with the anti-tamper detection device (502) between the head (512) and the first material layer (22); the fixing device (500) further comprising a lock (516) wherein the head (512) is locked to the body (514) by the lock (516) where there is no external magnetic field and wherein the head (512) becomes disengaged from the body (514) when the lock (516) is unlocked by an external magnetic field; and whereby the anti-tamper detection device (502) detects and records a change of the connection when the head (512) becomes disengaged. The anti-tamper system can be less "meter intrusive" than the prior art.

Abstract: Die Erfindung bezieht sich auf ein Manipulationsschutzsystem, das aufweist: eine Befestigungseinheit und eine Manipulationserkennungseinheit; wobei die Befestigungseinheit einen Körper und einen Kopf aufweist, wobei der Kopf einen größeren Querschnitt als das Körper aufweist, damit ein Werkzeug in Eingriff gelangen und den Körper in eine erste Materialschicht vortreiben kann, wodurch bei der Manipulationserkennungseinheit eine feste Verbindung zwischen dem Kopf und der ersten Materialschicht gebildet wird; die Befestigungseinheit ferner eine Verriegelungseinrichtung aufweist, wobei der Kopf durch die Verriegelungseinrichtung an dem Körper verriegelt ist, wenn kein externes Magnetfeld vorhanden ist, und wobei der Kopf von dem Körper gelöst wird, wenn die Verriegelungseinrichtung durch ein externes magnetisches Feld entriegelt wird; und wobei die Manipulationserkennungseinheit eine Änderung der Verbindung erkennt und dokumentiert, ob der Kopf gelöst wird. Das Manipulationsschutzsystem kann „weniger eingriffsintensiv” als Systeme nach dem Stand der Technik sein.
