The First International Workshop on Open Media Forensics Challenge ( OpenMFC 2021)

Dec. 7 -10, 2021


The first OpenMFC workshop (OpenMFC 2021) is in conjunction with TRECVID 2021. The TRECVID/OpenMFC workshop is a virtual event organized by teams in the Information Access Division (IAD), Information Technology Laboratory (ITL), National Institute of Standards and Technology (NIST) on Dec. 7-10, 2021.

The rapid advance of artificial intelligence (AI) has led to several emerging technologies such as deepfakes, CGI, provenance, and anti-forensics techniques, which significantly threaten the trustworthiness of media content. To detect inadvertent misinformation or deliberate deception via disinformation and ensure digital content trust and authentication, the NIST OpenMFC team provides public researchers with a comprehensive evaluation platform to develop technologies to detect unauthentic imagery and retrieve the digital content provenance. OpenMFC designed a set of evaluation tasks and released a series of media forensics datasets to support the OpenMFC evaluation as well as other related research work. The evaluation is being conducted to examine the performance of the system’s accuracy and robustness over diverse datasets. The participants can visualize their system performance on an online leaderboard evaluation platform. NIST will give an overview of the OpenMFC results in the current year and plan for OpenMFC evaluation for the next year.

Title: Local and Holistic Methods to Detect Fake Manipulated Images

Dr. Lakshmanan Nataraj, Principal R&D Engineer at Trimble Inc.

Dr. Lakshmanan Nataraj Image Abstract: Detecting images that have been digitally manipulated is a challenge. We have to rely on methods that specifically target certain manipulations, as well as other statistical and holistic methods that do not target a specific type of manipulation. This talk will address both these categories and show how these methods can be utilized in detecting doctored images.

Speaker Profile: Dr. Lakshmanan Nataraj is a Principal R&D Engineer at Trimble Inc., in Chennai, India, working in the areas of Computer Vision and Artificial Intelligence.

He was a Co-Principal Investigator (Co-PI) in DARPA's MediFor (MediFor) program as part of Mayachitra's team. During the course of the MediFor program, Dr. Nataraj co-authored several breakthrough publications in Media Forensics and led the team in obtaining top scores during the annual NIST Media Forensic Challenge (MFC) evaluations. Prior to joining Mayachitra, Dr. Nataraj obtained his Ph.D. from the University of California, Santa Barbara in 2015.

Title: Generation model attribution of face-swapped Deepfake videos

Dr. Shan Jia, Postdoctoral researcher at University at Buffalo, State University of New York

Dr. Shan Jia Image Abstract: High quality AI-created digital impersonations, known as Deepfakes, have become a serious problem from 2017, which could irreparably damage public trust in video content. Several publicly available generation tools and datasets have been proposed to promote a variety of detection methods. Beyond detection, it is also important to determine the specific generation model for a fake video, which can help attribute it to the source for forensic investigation. Dr. Jia will focus on this topic by investigating if and to what extent the manipulation tools will make differences in Deepfake videos.

Speaker Profile: Dr. Shan Jia is currently a postdoctoral researcher at the Department of Computer Science and Engineering of University at Buffalo, State University of New York, working with Professor Siwei Lyu. Before joining UB, she was a visiting scholar at West Virginia University, working with Professor Xin Li and Guodong Guo.

Title: Mobile steganography: Looking to the future

Professor Jennifer L. Newman, Iowa State University

Jennifer L. Newman Image Abstract: Humans have sent secret messages for millennia. A cousin to cryptography, steganography is the art and science of sending a secret message in the open by camouflaging the message carefully. Steganography can take many shapes, and its digital form often uses a digital image or video as a cover to hide the message. With a smartphone app, image steganography is easy to use, requires no expert knowledge of the science, and can be difficult to detect. To study mobile steganography properly, one must have a suitable database. This talk presents StegoAppDB, a database of digital photographs expressly created for studying mobile steganography, that will be used in NIST’s Open Media Forensic Challenge.

Speaker Profile: Prof. Jennifer L. Newman is Scott Hanna Faculty Fellow in Mathematics, Department of Mathematics Iowa State University. Her general research interests are applications of solutions to image processing problems using discrete mathematics. Her current research interest is in the area of forensic steganalysis, developing a standardized steganalysis dataset. Her past research interests have included the use of image algebra, genetic algorithms, artificial neural networks, stochastic processes, and optimization algorithms in areas such as image texture modeling for synthesis and classification; and image analysis - boundary detection, object recognition, and creating steganalysis feature sets. Her work is multidisciplinary and covers a broad range of topics from computer science, electrical engineering, mathematics, statistics, and machine learning techniques. She have taught many courses in mathematics, signal processing, image processing, digital image forensics, and related areas.
