Thanks to our attentive users, we realized that when running the Smart Report and Batch Processing tools over a set of files, the presence of some problematic files could stop the processing. More Robust Batch Processing and Smart Report

Should you need forensic soundness/reproducibility, you have to use the same software version employed at the time (it’s written on top of Authenticate’s reports!). While CRP files generated with previous versions of Amped Authenticate will still work, you may be getting different results using them with this new release. By filtering out these artifacts, we are reducing the chances of false positives. When extracting PRNU noise from images, the PRNU Identification filter now uses an improved filtering algorithm to reduce non-unique artifacts, that are, noise components that are not specific to the exact device, they are instead shared by many cameras. Doing so, if the image underwent both resize and crop, you may be able to detect a positive match and find the amount of resizing that yielded the match, which reveals further information about the image processing history. You can now configure an Advanced Settings File that lets you enable and customize a more in-depth searching strategy, that will iteratively resize the evidence image and test it against the CRP. In such cases, previous releases of Amped Authenticate would fail to find a positive match between the captured image and the corresponding device’s Camera Reference Pattern (CRP).Īnd now? Now it works! If you run the latest version of Amped Authenticate and select the PRNU Identification filter, you’ll notice a brand new section in the interface. Up-scaling combined with cropping is what happens when you capture an image using digital zoom, which is very common with smartphones. When the digital zoom is enabled, the image is obtained by taking a sub-part of the camera sensor and then resizing pixels to match the desired output resolution.
But one thing that was not supported was simultaneous down/up-scaling and cropping. One of the key performance indicators for source identification algorithms is robustness: will they find a match even if the image has been downscaled, compressed, or cropped?Īmped Authenticate’s PRNU Identification was already supporting a wide variety of processing: it would usually find the match even if the evidence image had been cropped (even by large amounts), downscaled, upscaled or re-compressed by reasonable amounts, or rotated by multiples of 90 degrees. The PRNU Identification is one of Amped Authenticate’s most attractive filters, with its ability to link an image to the source device that produced it.
