Abstract

本发明公开了一种面向异构具身智能设备的多模态数据注入防御方法,其步骤如下:1、构建标准化交叉验证接口,归一化采集多模态感知与物理数据;2、基于实时操作系统进行算力调度,在线求解设备预期状态;3、采用基于运动非线性度的自适应多模型滤波计算时空残差,依据马氏距离特征识别多传感器叠加自然故障;4、构建强化学习驱动的场景自适应阈值,对轨迹一致性、时延熵值与跨模态物理关联度进行量化打分;5、执行跨网络行为指纹溯源、场景感知局部安全降级,并引入基于指数惩罚的信任恢复策略。本发明解决了具身智能设备算力受限、极端环境干扰、判定标准缺乏及易受变种攻击等问题,实现了高鲁棒性的全链路安全防御。
