| 摘要 | A system and method for rights protection of a dataset that includes multiple trajectory objects includes determining an intensity power for embedding a watermarking key in a data trajectory. The data trajectory is modified to embed a watermarking key at the intensity power such that the intensity power guarantees an original pair-wise relationship between distance-based neighboring objects before and after embedding of the key such that a modified trajectory provides a watermarked version of the data trajectory. | ||

| 主权项 | 1. A method for rights protection of a dataset that includes multiple trajectory objects, comprising: determining an intensity power for embedding a watermarking key in a data trajectory; and modifying the data trajectory using a processor to embed a watermarking key at the intensity power such that the intensity power guarantees that an original pair-wise nearest neighbor relationship is maintained between distance-based neighboring objects before and after embedding of the watermarking key such that a modified trajectory provides a watermarked version of the data trajectory. | ||
