Objective: Verify the authenticity and context of multimedia content, which may be in a language other than English, and provide both a detailed report for fact-checkers and a concise summary for general readers. The languages of the content might not be in English.
Input: Each case/task will provide (in a zip file):
Multimedia Content: Image(s) or video(s)
Associated Context: Captions, descriptions, social media posts, news articles, metadata (if available)
Additional Clues: Possible sources, claims, or fact-checker notes (if relevant)
Output: A verification report (as a text file) in English. The report should include the following key information:
Summary of Key Points: Provide a concise overview of the content, including relevant details. Clearly highlight any uncertainties and underline what is not yet known.
Content Category: Assign relevant tags based on platforms, people, brands, or specific topics.
Forensic Analysis Results:
Authenticity: Determine if the content is synthetic, modified, or recaptured.
Tools & Methods Used: Specify the verification tools and techniques applied.
Synthetic Type (if applicable): Identify whether it was generated using GANs, Stable Diffusion, or other AI models.
Other Artifacts: Note any detected anomalies or manipulations.
Verified Evidence: State what can be confirmed about the video/photo based on available evidence.
Source Details: Where the content comes from (URLs, original posts, etc.)
Where? (Location)
When? (Time)
Who? (People, organizations, entities involved)
Why? (Possible motivations or intent)
Other Evidence & Findings: Any additional relevant information, supporting materials, or external sources
Note: For each evidence finding, specify the failure type if verification fails: Indeterminate (insufficient or ambiguous data), Inconclusive (attempted but no definitive result), or Not Feasible (limited expertise or tools).
Stage 1 – Training (March). Organizers provide 50 known cases with inputs and expected outputs. Participants register, explore the tasks, and practice verification.
Stage 2 – Validation (March). Organizers release 10 new cases with input only. Participants submit verification reports and describe their methodology, and may optionally submit a scientific paper. Submissions are evaluated, and only teams that pass the validation stage qualify for the final competition.
Stage 3 – Real-World Verification (April 7–15 14 - 22). Only validated teams advance. Organizers provide 10 real-time cases reflecting ongoing misinformation challenges. Participants verify the cases, submit results, and may optionally submit a camera-ready paper.
This challenge is open for researchers, fact-checkers, and relevant professionals. Participants have two options for submission:
With ICMR 2026 Publication
Without ICMR 2026 Publication
Each team is expected to submit two artifacts:
Results
Reports or Papers
The format and requirements for each artifact depend on the publication option chosen.
Option 1: Freestyle Report (Non-Publishing Option)
For teams not intending to publish with ICMR 2026, a freestyle report is required.
Format:
PDF Document
Freestyle Text that provides a detailed explanation of the approach and methodology used to solve the challenge.
There are no strict formatting guidelines; however, clarity and structure are encouraged.
Option 2: Technical Paper (ICMR 2026 Publishing Option)
For teams intending to publish with ICMR 2026, a technical paper (4 pages + plus additional pages for the list of references) must be submitted.
All papers must be formatted according to the ACM proceedings style. Click here to access LaTeX and Microsoft Word templates for this format. If you use LaTeX, please use sample-sigconf.tex as the template (or see the Overleaf template here).
ACM ICMR will use a single-blind review process for the technical challenges paper selection. Authors should provide author names and affiliations in their manuscript. Links to working prototypes and videos showcasing the capabilities of the systems are encouraged with the submission for demo papers.
All challenge submissions will be peer-reviewed to ensure maximum quality and accepted papers will be included in the conference proceedings. The best challenge will be awarded and announced.

Reports or Papers Submissions are handled via the EasyChair:
Participants must submit ZIP files that contain a detailed verification report in Markdown (.md) format for each assigned case (10 validation cases of Stage 1 and 10 live cases if the team is qualified for the Final Stage). The submission should follow these guidelines:
Reports must be in Markdown (.md) format. The file name of the report is report.md
Folder report contains supporting media files for the MD file.
The submission file for each case is the ZIP file that contains above files and folders with this name: teamname_caseID.zip

Report Structure
# Case Summary
- Brief overview of the verification findings.
# Content Classification
- **Tags:** Assign relevant tags based on platforms, people, brands, or specific topics (e.g., TikTok, Trump, Coca-Cola, Ukraine War, or AI-generated).
# Verified Evidence
- **Source Details:** Identify where the content originates (URLs, original posts, metadata).
- **Where? (Location):** Determine the correct geographical context.
- **When? (Time):** Establish the accurate timeframe.
- **Who? (Entities Involved):** Identify key individuals or groups.
- **Why? (Motivation or Intent):** Provide a reasoned explanation of possible intent.
# Forensic Analysis
- **Authenticity Assessment:** Determine if the content is synthetic, modified, or recaptured.
- **Verification Tools & Methods:** Clearly document the tools and techniques used.
- **Synthetic Type (if applicable):** Identify AI-generated content (e.g., GANs, Stable Diffusion).
- **Other Artifacts:** Note any detected anomalies or manipulations.
# Other Evidence & Findings
- **Supporting Sources:** Use additional fact-checks, reports, or metadata to back claims.
- **Cross-Checking Information:** Ensure verification through multiple independent sources.
- **Other Info:** Unclassified supporting evidence and analysis.
