Abstract: A tamper proof locking mechanism incorporating a first fixture for attachment to an index protective cover, a second fixture for attachment to an instrument, and a third fixture for connecting the first fixture to the second fixture. The first fixture may have a receptacle, the second fixture may have a plate with an opening, and the third fixture may have a protrusive structure that fits into the receptacle of the first fixture and into the opening in the plate to connect the first fixture to the second fixture. The protrusive structure may have a rivet that is partially embedded with a plastic-like material that reveals tampering when an attempt is made to break a connection between the first fixture and the second fixture.

Abstract: A security seal identification that may be matched with an identification of a utility measuring meter. This matching may be done, for instance, by a code which is imprinted on the seal and then matched to a meter number in a database, or by a code such as an encryption of the number assigned to the meter. An encryption may be read by an app on a smartphone or checked offline to determine whether the seal belongs to the meter or if it was altered or changed. A mismatch of numbers or symbols may generally indicate a change or manipulation and warrant an investigation.
