Publicly available dataset with both hand-vein and fingerprint data from the same subjects?

Hello,

I am working on a biometric fusion study in MATLAB and I am looking for a publicly available dataset that contains both hand-vein images and fingerprint images acquired from the same individuals.

I initially planned to use the following dataset:

• (2010) PolyU Palm Vein Dataset, The Hong Kong Polytechnic University.Accessed: 2025-12-17.Available online at the PolyU Biometrics Research Centre.

However, as far as I can determine, this dataset provides only palm/hand-vein data and does not include fingerprint images from the same subjects.

I would like to ask:

1. Is there any publicly available dataset that includes both hand-vein and fingerprint modalities for the same subjects?
2. If such a dataset does not exist, what is the recommended approach for fusion experiments when modalities come from separate datasets?
3. Are there any MATLAB-based workflows or tools commonly used for multimodal biometric fusion?

Any guidance or references would be appreciated.

Thank you.
