一种多模态生物特征比对的发药权限控制方法及系统
By using a multimodal biometric comparison method, face and iris images are simultaneously acquired and analyzed to generate live physiological resonance feature values. This solves the problems of easy leakage of identity verification and insufficient robustness of single-modal recognition in existing technologies, and achieves high-precision identity verification and accurate drug dispensing.

Abstract
本发明涉及生物识别技术领域，具体公开了一种多模态生物特征比对的发药权限控制方法及系统，所述方法包括：采集人脸可见光图像序列和虹膜红外图像序列，提取瞳孔变化曲线和微表情肌肉颤动频次，并进行时域对齐，生成活体生理共振特征值；对关键帧虹膜图像进行小波变换，得到虹膜相位特征张量，对关键帧人脸图像进行深度卷积特征提取得到人脸语义特征张量；对两个特征张量进行特征级异构融合，生成高维联合生物特征嵌入向量；将权限标识映射为授权生物特征张量基，将高维联合生物特征嵌入向量与授权生物特征张量基进行距离度量，若度量距离小于类内聚合阈值，则生成校验通过信号；本发明可以提高发药权限控制的防伪能力和识别精度。
