Abstract Motivated by the large dissemination of images through the internet, tools that guarantee the veracity of suspicious images are more and more necessary. A fake image can cause problems of unimaginable size and this type of problem can be avoided by developing and deploying new digital forensic techniques for document analysis. For organs like Federal Police and the Judiciary, this kind of methods are essential. The result of an image analysis can easily change the direction of an investigation process, for example. The analysis of an expert based on an appropriate scientific method is essential in the context of a proper judgment by a judge. This project proposes the investigation of a method to perform the detection of image splicing. Our proposal is to develop a method that detects inconsistencies in the illumination of images using illuminant maps, which highlight these types of inconsistencies in fake images and robust architectures of deep convolutional networks in order to detect when and where falsifications of the composition type occur. | |
