                         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.",
