The deep convolutional network (DCN) suffers from drawbacks such as high computational complexity and slow speed. To address these issues and facilitate the deployment of DCNs in embedded devices, we propose a finger vein recognition method based on lightweight Efficient Channel Attention (ECA) mechanism and GhostNet. By combining the ECA mechanism with the GhostNet's G-bneck, we create a new module called ECAGhostNet. Additionally, we establish a more realistic FV-UST dataset for finger vein door locks which includes images with various challenges like rotation, stains, skin damage, hand sweat, temperature variations, and illumination differences. Experimental results demonstrate that ECAGhostNet outperforms GhostNet on the public FV-USM dataset, improving accuracy by 0.82% with minimal parameter increase (1.9 M). On the self-built FV-UST dataset, ECAGhostNet achieves a 0.63% accuracy improvement over GhostNet. Furthermore, we validate the effectiveness of our proposed model on the Jetson Nano device, confirming its suitability for real-world embedded applications.
