Abstract
A computer-implemented method and transaction terminal is disclosed. The method comprises capturing, by an imaging device, a first image of an internal region of an apparent peripheral device of the transaction terminal, calculating, by a processor of a transaction terminal, a first amount of change between the first image and a baseline image of the internal region, capturing, by the imaging device, at least one further image of the internal region, for each further image, calculating, by the processor, a second amount of change between the further image and a respective baseline image of the internal region, and when at least two consecutive values of the first and/or second amount of change are below a predefined value, determining that the imaging device is in a dummy peripheral device to prevent detection of a foreign object in an active peripheral device of the transaction terminal.
