Forensic Fingerprint Dataset

This fingerprint database contains 6,000+ fingerprint images collected from 100 individuals, with samples covering both hands and all ten fingers per person. The dataset is designed for forensic matching, denoising, and minutiae extraction tasks and includes rich metadata such as gender, age, finger type, and hand orientation. All images in this fingerprint dataset were captured using a ZKTeco ZK9500 optical scanner and are provided in PNG and BMP formats, making the data well-suited for biometric identification and security research.

Dataset Use Cases

  • Security

    Robust Authentication for Consumer Devices

    This forensic fingerprint dataset supports security teams in improving fingerprint sensors used in smartphones, laptops, and access control systems. The fingerprint image dataset includes varied fingerprint patterns and quality levels, allowing recognition algorithms to handle smudged, partial, or low-contrast inputs. It strengthens fingerprint identification under real-world conditions common in everyday device use.

  • Liveness Detection

    Liveness Detection Against Spoofing Attacks

    For liveness detection, fingerprint dataset helps identify synthetic and spoofed prints based on distortion patterns and texture inconsistencies. By training on biometric data that reflects realistic attack scenarios, security systems learn to separate real fingerprints from fake impressions. This improves resistance to presentation attacks and strengthens authentication reliability.

  • Government and Border Control

    Visa and Passport Finger Processing at Scale

    Border control agencies use this fingerprint database to improve high-throughput identification systems. The forensic dataset supports fingerprint recognition when scans are noisy, incomplete, or captured under time pressure. It helps identification systems process large volumes of travelers while maintaining accuracy, supporting national databases, and automated fingerprint identification systems.

  • Government and Border Control

    Disaster Victim Identification and Recovery

    In disaster victim identification, this dataset can help match compromised or partial prints collected from difficult environments. The database contains fingerprint images suitable for forensic investigations where traditional biometric signals are degraded. It supports forensic scientists and law enforcement during scene investigations, accelerating identification processes when time and accuracy are critical.

FAQs

What is included in this dataset?
This fingerprint dataset includes 6,000+ fingerprint images collected from 100 individuals, covering two hands with five fingers per hand. The images are intended for forensic matching, denoising, and minutiae extraction tasks and represent consistent, scanner-captured fingerprint samples rather than paired latent-reference prints.
What types of annotations are provided?
The fingerprint image dataset is annotated with structured metadata, including gender, age, hand (left/right), and finger type. These annotations support biometric analysis, fingerprint classification, and supervised machine learning workflows without relying on latent-to-reference correspondence labels.
Can I request a sample of the dataset before purchasing?
Yes. You can request a free sample to evaluate the quality of fingerprint images, annotation accuracy, and variation in latent prints. This helps verify compatibility with your forensic recognition systems or AI fingerprint classification models before making a full purchase.
How are Unidata datasets licensed?
Unidata datasets follow a dual-licensing model: free samples are offered for evaluation, while full datasets are available exclusively through purchase. This ensures flexible access for both research and enterprise use.
How are Unidata datasets stored?
All datasets are securely hosted on AWS cloud infrastructure, following ISO 27001 and ISO 27701 standards. This guarantees high data availability, secure access, and privacy compliance for all dataset transactions and storage.
How long does it take to receive the dataset?
Once your request is submitted, the Unidata team will contact you to review details and complete the necessary documentation. After signing and payment, the dataset is delivered within 3–10 business days through a secure download link.
How was the data collected?
All data was collected through crowdsourcing platforms, involving volunteers who provided controlled and varied fingerprint impressions. This method ensures high diversity, realistic distortion patterns, and reliable forensic scenarios for both academic and professional research.
Is this a real-world dataset or synthetic data?
This is a real-world dataset, collected from human participants via crowdsourcing, not AI-generated. The dataset accurately reflects the complexity of real forensic evidence, including latent prints and environmental distortions.

Very good experience

We got in touch with UniData to buy several datasets from them. Communication was very cooperative, quick, and friendly. We were able to find contract conditions that suited both parties well. I also appreciate the team's dedication to understand and address the needs of the customer. And the datasets we bought from UniData matched with our expectations.

Data purchase

Our team got in touch with UniData for purchasing video data. The team at UniData was transparent, timely, and pleasant to communicate and negotiate with. Their samples and descriptions aligned well with the data we received. We will certainly reach out to UniData again if we're in search of 3rd party video data.
