OpenMFC Tasks Summary

In general, there are multiple tasks in media forensic applications. For example, manipulation detection and localization, Generative Adversarial Network (GAN) detection, image splice detection and localization, event verification, camera verification, and provenance history analysis etc.

The OpenMFC initially focuses on manipulation detection and deepfake tasks. In future, challenges may be expanded with community interest. The OpenMFC 2022 has following three task categories: Manipulation Detection (MD), Deepfakes Detection (DD), and Steganography Detection (StegD).

  • MD: Manipulation Detection
  • DD: Deepfakes Detection
  • StegD: Steganography Detection

A brief summary of each category and their tasks are described below. In the summary, the evaluation media is described in the following way: A ‘base’ indicates original media with high provenance, while a ‘probe’ indicates a test media. A ‘donor’ indicates another media whose content was donated into the base media and generated the probe media. For a full description of the evaluation tasks, please refer to the OpenMFC 2022 Evaluation Plan [Download Link].

  • Manipulation Detection (MD)

    The objective for Manipulation Detection (MD) is to detect if a probe has been manipulated, and if so, to spatially localize the edits. Manipulation in this context is defined as deliberate modifications of media (e.g., splicing and cloning etc.) and localization is encouraged but not required for OpenMFC.

    The MD task includes three tasks, namely,

    • Image_MD (or IMD): Image Manipulation Detection
    • The Image Manipulation Detection task is to detect if the image has been manipulated, and then to spatially localize the manipulated region. For detection, the IMD system provides a confidence score for all probe (i.e., a test image) with higher numbers indicating the image is more likely to have been manipulated. The target probes (i.e., probes that should be detected as manipulated) included potentially any image manipulations while the non-target probes (i.e., probes not containing image manipulations) include only high provenance images that are known to be original. Systems are required to process and report a confidence score for every probe.

      For the localization part of the task, the system provides an image bit-plane mask (either binary or greyscale) that indicates the manipulated pixels. Only local manipula­tions (e.g., clone) require a mask output while global manipulations (e.g., blur) affecting the entire image do not require a mask.

    • ImageSplice_MD (or ISMD): Image Splice Manipulation Detection
    • The new task, Image Splice Manipulation Detection, is added in the OpenMFC 2022 to support entry-level public participants. The ISMD is designed for 'splice' manipulation operation only. The testing dataset is a small-size dataset (2K images), which contains either original images without any manipulation, or spliced images. The ISMD task will detect if a probe image has been spliced.

    • Video_MD (or VMD): Video Manipulation Detection
    • The Video Manipulation Detection (VMD) task is to detect if the video has been manipulated. In this task, the localization of spatial/temporal-spatial manipulated regions is not addressed. For detection, the VMD system provides a confidence score for all probes (i.e, a test video) with higher numbers indicating the video is more likely to have been manipulated. For VMD, target probes (i.e., probes that should be detected as manipulated) included potentially any video manipulations while the non-target probes (i.e., probes not containing video manipulations) include only high provenance videos that are known to be original. Systems are required to process and report a confidence score for every probe.

  • Deepfakes Detection (DD)

    With recent advances in DeepFakes techniques and GAN (Generative Adversarial Network), imagery producers are able to generate realistic fake objects in media. The objective for Deepfakes Detection (DD) is to detect if a probe has been Deepfakes or GAN manipulated.

    The DD task includes two tasks based on testing media type, namely,

    • Image_DD (or IDD): Image Deepfakes Detection
    • The Image Deepfakes Detection task evaluates if a system can detect Deepfaked images (e.g. a face video is manipulated by a Deepfakes tool, then deepfaked face image frames are extracted as image files etc.) or GAN-manipulated images (e.g. created by a GAN model, locally/globally modified by a GAN filter/operation, etc.) specifically while not detecting other forms of manipulations. In the testing datasets, the non-target probes are high provenance images (or cropped high provenance images) and the target images are the ones manipulated with Deepfakes or GAN techniques.
    • Video_DD (or VDD): Video Deepfakes Detection
    • The Video Deepfakes Detection task evaluates if a system can detect Deepfaked videos. The target probes include Deepfaked videos while the non-target probes include high provenance original videos or video clips.
  • Steganography Detection (StegD)
    • StegD: Steganography Detection
    • The Steganography Detection task evaluates if a probe is a stego image, which contains the hidden message either in pixel values or in optimally selected coefficients. For each StegD trial, which consists of a single probe image, the StegD system must render a confidence score with higher numbers indicating the probe image is more likely to be a stego image.
Conditions

All probes must be processed independently of each other within a given task and across all tasks, meaning content extracted from probe data must not affect another probe.

For the OpenMFC 2022 evaluation, all tasks should run under the following conditions:

  • Image Only (IO)

    For the image tasks, the system is only allowed to use the pixel-based content for images as input to the system. No image header or other information should be used.

  • Video Only (VO)

    For the video tasks, the system is only allowed to use the pixel-based content for videos and audio (if audio exists) as input. No video header or other information should be used.

Metrics

For detection performance assessment, system performance is measured by Area Under Curve (AUC) which is the primary metric and the Correct Detection Rate at a False Alarm Rate of 5% (CDR@FAR = 0.05) from the Receiver Operating Characteristic (ROC) as shown Figure (a) below. This applies to both image and video tasks.

For the image localization performance assessment, the Optimum Matthews Correlation Coefficient (MCC) is the primary metric. The optimum MCC is calculated using an ideal mask-specific threshold found by computing metric scores over all pixel thresholds. Figure (b) below shows a visualization of the different mask regions used for mask image evaluations.

  • TP (True Positive) is an overlap area (green) of the reference mask and system output mask as manipulated at the pixel threshold.
  • FN (False Negative) is the reference mask indicates as manipulated, but the system did not detect it as manipulated at the threshold (red).
  • FP (False Positive) is the reference mask indicates not-manipulated, but the system detected it as manipulated at the threshold (orange).
  • TN (True Negative) is the reference mask indicates not-manipulated, and the system also detects it as not-manipulated at the threshold (white).
  • NS (No-Score) is the region of the reference mask not scored, the result of the dilation and erosion operations (purple).
  • If the denominator is zero, then we set MCC_o = 0.
  • If MCC_o = 1, there is a perfect correlation between the reference and system output masks.
  • If MCC_o = 0, there is no correlation between the reference mask and the system output mask.
  • If MCC_o = -1, there is perfect anti-correlation.

    Rules
    • Participation in the OpenMFC20 evaluation is voluntary and open to all who find the task of interest and are willing and able to abide by the rules of the evaluation. To fully participate a registered site must:
      • become familiar with, and abide by, all evaluation rules;
      • develop/enhance an algorithm that can process the required evaluation datasets;
      • submit the necessary files to NIST for scoring; and
      • attend the evaluation workshop (if one occurs) and openly discuss the algorithm and related research with other evaluation participants and the evaluation coordinators.
    • Participants are free to publish results for their own system but must not publicly compare their results with other participants (ranking, score differences, etc.) without explicit written consent from the other participants.
    • While participants may report their own results, participants may not make advertising claims about their standing in the evaluation, regardless of rank, or winning the evaluation, or claim NIST endorsement of their system(s). The following language in the U.S. Code of Federal Regulations (15 C.F.R. § 200.113)14 shall be respected: NIST does not approve, recommend, or endorse any proprietary product or proprietary material. No reference shall be made to NIST, or to reports or results furnished by NIST in any advertising or sales promotion which would indicate or imply that NIST approves, recommends, or endorses any proprietary product or proprietary material, or which has as its purpose an intent to cause directly or indirectly the advertised product to be used or purchased because of NIST test reports or results.
    • At the conclusion of the evaluation, NIST may generate a report summarizing the system results for conditions of interest. Participants may publish or otherwise disseminate these charts, unaltered and with appropriate reference to their source.
    • During the OpenMFC20 evaluation, a maximum of ten system slots per task can be created. There are no limits on the number of submissions per system slot.
    • The challenge participant can train their systems or tune parameters using any data complying with applicable laws and regulations.
    • The challenge participant agrees not to probe the test images/videos via manual/human means such as looking at the media to produce the manipulations from prior to the evaluation period to end of leaderboard evaluation.
    • All machine learning or statistical analysis algorithms must complete training, model selection, and tuning prior to running on the test data. This rule does not preclude online learning/adaptation during test data processing so long as the adaptation information is not reused for subsequent runs of the evaluation collection.
    How to submit system outputs
    System output and documentation submission to NIST for subsequent scoring must be made using the submission protocol as per eval plan which consists of four steps:

    1. preparing a system description and self-validating system outputs
    2. packaging system outputs and system descriptions
    3. uploading data to a publicly accessible webserver
    4. transmitting the url in form of a task-submission using this website

    • System Descriptions

      Documenting each system is vital to interpreting evaluation results. As such, each submitted system, determined by unique submission identifiers, must be accompanied by Submission Identifier(s), System Description, OptOut Criteria, System Hardware Description and Runtime Computation, Training Data and Knowledge Sources, and References.

    • Packaging Submissions

      Using the <SubID> (a team-defined label for the system submission, witout spaces or special characters), all system output submissions must be formatted according to the following directory structure:

      <SubID>/
       <SubID>.txt         The system description file, described in Appendix A-a
       <SubID>.csv        The system output file
       /mask             The system output mask directory
        {MaskFileName1}.png  The system output mask file directory

      As an example, if the team is submitting  <SubID> baseline_3, their directory would be:
       baseline_3/
        baseline_3.txt
        baseline_3.csv
        /mask

      Next, build a zip or tar file of your submission and post the file on a web-accessible URL that does not require user/password credentials.

    • Transmitting Submissions

      Make your submission using the OpenMFC Web site. To so, follow these steps:

      • Navigate to your “Dashboard”
      • Under “Submission Management”, click the task to submit to.
      • Add a new “System” or use an existing system.
      • Click on “Upload”
      • Fill in the form and click “Submit”

    System output
    The MediScore package contains a submission checker that validates the submission in both the syntactic and semantic levels. Participants should check their submission prior to sending them to NIST. NIST will reject submissions that do not pass validation. The OpenMFC20 evaluation plan contains system output formats and instructions for how to use the validator. NIST provides the command line tools to validate OpenMFC20 submission files. Please refer to the OpenMFC20 evaluation plan for the details.

    MaskScorer - Single/Double Source Mask Evaluation (Localization) Scorer
    ProvenanceFilteringScorer - Scorer for Provenance Filtering
    ProvenanceGraphBuildingScorer - Scorer for Provenance Graph Building
    VideoTemporalLocalisationScoer - Scorer for Video Temporal Localization

    The MediScorer package git repository is available here. OpenMFC only needs Validator, DetectionScorer, and MaskScorer.
    Annotation Tools (Journaling Tool)
    The Journaling Tool (JT) is an automatic tool to aim data and metadata collections, annotations, and generation of automated manipulations designed according to data collection requirements. The intent of journaling is to capture a detailed history graph for each media manipulated project that results in a set of one or more final manipulated media files. The data collection process requires media manipulators to capture the detailed steps of manipulations during the manipulation process. In order to reduce the burden on human manipulators, automation is built into the capture process to record incremental changes via mask generation and change analysis. Please refer to the paper [citation-Manipulation Data Collection and Annotation Tool for Media Forensics] for the details.

    You can download the Journaling Tool package from Github.
