Latest Patents

One of Mengjun Leng's latest patents is centered around "Replay spoofing detection for automatic speaker verification system." This invention describes a system and techniques for detecting whether biometric data provided in an access request is genuine or a replay. The system employs a machine learning model trained using both genuine and replay sample data. This model is optimized to produce a result set where genuine samples are pulled closer to a genuine center, while replay samples are pushed away. By subjecting input biometric data, such as an audio sample, to this trained model, the system can classify the data as either genuine or replay. This classification is crucial for determining the validity of the input biometric data.
