%X Frauds involving illegal modifications to the printedcircuit boards from fuel pump controllers are a serious problem,which not only harms customers, but also connects to othercrimes, such as money laundering and tax evasion. The currentstate-of-practice for inspecting these boards is a visual analysisperformed by a human. In this paper, we introduce an image-based approach that can provide support to the human inspectorby automatically detecting suspicious regions in the boards.The proposed approach aligns a photograph of the inspectedboard to a reference view, partitions the image in sub-regions,extracts features using a variation of the popular Scale-InvariantFeature Transform, classifies the features against previouslytrained Support Vector Machines, and integrates the results forpresentation. In experiments performed on a dataset containing649 images from a board, with and without modifications, ourapproach achieved a precision of 0.7739, a recall of 0.9434, andanF-measure 0.8503. These results indicate that our approachcan effectively identify suspicious regions, providing invaluablehelp to the human inspector.
