About the Challenge
Challenge Overview
The Forensic Handwritten Document Analysis (FHDA) Challenge invites participants to tackle the binary classification task of determining whether a given pair of handwritten documents were authored by the same individual.
This competition introduces a unique cross-modal comparison between traditional handwritten documents (scanned) and documents written directly on digital devices such as tablets or graphic tablets.
Challenge Significance
The FHDA Challenge holds paramount importance in forensic science, writer identification, and document authentication.
Precise authorship verification is essential for:
- Detecting document forgery
- Ensuring the integrity of legal documents
- Strengthening forensic investigations
- Historical manuscript studies
Challenge Objective
Develop innovative solutions or architectures to achieve higher accuracy in authorship verification across different writing modalities. The dataset encompasses diverse handwriting styles, writing instruments, and environmental conditions, making it representative of real-world forensic challenges.
Evaluation Criteria
Models will be evaluated based on a composite score calculated by multiplying the number of correct classifications by the assigned probability for each comparison. This weighted accuracy approach rewards both correctness and appropriate confidence levels in predictions.
Dataset Information
A novel dataset will be exclusively released for this challenge, consisting of:
- Handwritten documents written on paper and later scanned
- Documents written directly on digital devices
- Paired documents for comparative analysis
The dataset will encompass diverse handwriting styles, writing instruments, and environmental conditions, making it representative of real-world forensic handwriting analysis challenges.
Dataset Access and Details: The dataset download links, detailed specifications, and any updates will be made available on the official challenge GitHub repository: https://github.com/mfs-iplab/fhda-challenge. Participants are encouraged to monitor the repository for the latest information.
Scoring System
For each pair of documents, participants must:
- Determine whether the documents were written by the same author (binary classification)
- Provide a confidence percentage for each comparison
The final score will be calculated by multiplying the number of correct classifications by the assigned probability for each comparison. The team with the highest overall score wins the challenge.

Frequently Asked Questions
What is the main goal of this challenge?
The main goal is to develop innovative solutions for authorship verification in handwritten documents, particularly focusing on cross-modal comparison between traditional pen-and-paper documents and digitally written samples.
Who can participate in the challenge?
The challenge is open to researchers, developers, and students from academic institutions and industry with interest in document analysis, pattern recognition, and machine learning.
How will submissions be evaluated?
Submissions will be evaluated using a scoring system that multiplies the number of correct authorship classifications by the confidence percentage assigned to each comparison. This rewards both accuracy and appropriate confidence levels in your predictions.
What should my submission include?
Your submission must include your architecture details, dataset management approach, a brief methodology description, and preliminary results. All submissions must be in English and follow the provided templates.
Where can I find the dataset and related resources?
All dataset download links, detailed specifications, and updates will be available on the official challenge GitHub repository: https://github.com/mfs-iplab/fhda-challenge.
