Researchers have developed a new method for watermarking time-series data generated by AI models, addressing a key limitation in current techniques. Existing watermarking methods often fail under post-editing attacks because their detectors rely on global re-encoding, which can unpredictably alter detection scores. The proposed solution, LVQMark, utilizes a locally tokenized generative model called L-VQVAE, where each token is generated from a small temporal window. This localized approach ensures that detection remains stable and reliable even after data modifications, as demonstrated in experiments across finance, energy, and neuroimaging datasets. AI
