Abstract: A contactless palm vein authentication system (Fig. 1) images the subcutaneous vascular network of a subject’s palm at four infrared wavelengths, namely approximately 700, 850, 940 and 1300 nm, using a multi-channel CMOS sensor array (104) carrying narrowband bandpass filters (516) and driven by an infrared illumination array (102), thereby capturing venous structures at multiple tissue depths. A signal processing module (200) pre-processes and spatially registers the channel images, fuses them using learnable per-channel weights (204), and extracts a 512-dimensional descriptor through a trained convolutional neural network (206). A liveness detection module (208) rejects spoof presentations using spectral-reflectance, photoplethysmographic and depth cues. A security module (300) protects enrolled templates by a cancelable transformation and AES-256-GCM encryption (302), preventing template inversion and cross-database linkage. End-to-end authentication latency does not exceed 500 milliseconds.
