Methods and apparatuses for authenticating a biometric scanner, such as area type finger print scanners, involves estimating unique intrinsic characteristics of the scanner, that are permanent over time, and can identify a scanner even among scanners of the same manufacturer and model. In accordance with the game, a player attempts to play one or more dominos. The simulation system also contains a simulation part 15 which predicts a change of geometry of the cardiac structure model produced by pressure load utilizing finite element method with computation. Next, the system monitors the low-resolution data, and while doing so, determines if an anomaly exists in the low-resolution data. The edge protector grips behind the back surface with counter-support surfaces. Otherwise, the first signal is processed by the processing circuitry.
