The authors adapt backdoor watermarking to hyperdimensional computing classifiers by training secret out-of-distribution triggers with target labels, then verifying them through black-box predictions. At 1% exposure, AdaptHD and OnlineHD pass both verification thresholds on four benchmarks, while Vanilla HDC fails. On ISOLET, OnlineHD achieves 93.29% test accuracy and 48.3/50 trigger matches; tested extraction surrogates lose the trigger associations.
