Join us this week at the IACP Virtual Training Event and Expo

From October 21 – 23, Amped Software will be exhibiting at the IACP 2020 Virtual Training Event and Expo

Video evidence is becoming a crucial component of cases and official investigations, and two things have become ever apparent. First, it is crucial that agencies review these videos accurately to make sure they get the best evidence. Second, agencies need a fast and easy way to get relevant information out to the public or other agencies.

We are excited to be able to share with the attendees at IACP 2020 the tools we have, which are helping agencies worldwide, to convert and play video accurately from any source without the need for other applications, and to generate actionable images and videos with annotations and redactions.

Come and see more at the Amped Software “booth” in the virtual expo hall. Remember that the hall will be open a full day before programming so you have lots of time to come see us! Schedule meetings or “drop a business card” to interact with us once the platform is available. 

While you can explore the expo hall anytime, company representatives will be available from 10:00 a.m. to 4:00 p.m. Tuesday, October 20 – Thursday, October 22. 

See you there!

Is PRNU Camera Identification Still Reliable? Tests on Modern Smartphones Show We May Need a New Strategy!

Dear Amped friends, today we’re sharing with you something big. If you’ve been following us, then you know that Amped invests lots of resources into research and testing. We also join forces with several universities to be on the cutting edge of image and video forensics. During one of these research ventures with the University of Florence (Italy), we discovered something important regarding PRNU-based source camera identification.

PRNU-based source camera identification has been, for years, considered one of the most reliable image forensics technologies: given a suitable number of images from a camera, you can use them to estimate the sensor’s characteristic noise (we call it Camera Reference Pattern, CRP). Then, you can compare the CRP against a questioned image to understand whether it was captured by that specific exemplar. You can read more about PRNU here.

Since its beginnings, the real strength of PRNU-based source camera identification was that false positives were extremely rare, as shown in widely acknowledged scientific papers. The uniqueness of the sensor fingerprint was so strong that researchers were even able to cluster images based on their source device, comparing the residual noise extracted from single images, in a one-vs-one fashion. We tested this one-vs-one approach over the VISION dataset, which is composed of images captured with 35 portable devices (released roughly between 2010 and 2015), and actually, it worked. Take a look at the boxplot below. On the X-axis you have the 35 different devices in the VISION dataset (click here to see the list). For each device, the vertical green box shows the PCE values obtained comparing couples of images captured by the device itself (the thick box covers values from the 25th to the 75th percentiles, the circled black dot is the median value, isolated circles are “outlier” values). Red boxes and circles represent the PCE values obtained comparing images of the device against images of other devices. As expected, for most devices the green boxes lay well above the dashed horizontal line sitting on 60, which is the PCE threshold commonly used to claim a positive match. Most noticeably, we have no red circles staying well above the PCE threshold: yes, there are some here and there sporadically, but they’re still at values below 100, so we can call these “weak false positives”.

But with all the computations that happen inside modern devices, is PRNU still equally reliable? To answer this question, we’ve been downloading thousands of images from the web, filtering them so to take only pictures captured with recent (2019+) smartphones. We also filtered out images having traces of editing software in their metadata, and we applied several heuristic rules to exclude images that seemed to be not camera originals. For some devices, we also collected images at two of the default resolutions. We then grouped images by uploading users, assuming that different users take pictures with different exemplars and that a single user only owns one exemplar. Now, take a look at what happened when we tested Samsung smartphones.
