Since most of the research efforts focus on modality-specific anti-spoofing techniques, building a unified, resource-efficient solution across multiple biometric modalities remains a challenge. To address this, we propose LitMAS, a $\\textbf{Li}$gh$\\textbf{t}$ weight and generalizable $\\textbf{M}$ulti-modal $\\textbf{A}$nti-$\\textbf{S}$poofing framework designed to detect spoofing attacks in speech, face, iris, and fingerprint-based biometric systems.
