Lucchese C., Vlachos M., Rayan D., Yu P. S. Rights protection of trajectory datasets. In: 24th International Conference on Data Engineering (Cancún, Mexico, 7-12 Aprile 2008). Proceedings, pp. 1349 - 1351. IEEE Computer Society, 2008.
This work presents a technique of convincingly claiming ownership rights over a trajectory dataset. The presented methodology distorts imperceptibly a collection of sequences, effectively embedding a secret key, while retaining as well as possible the neighborhood of each object, which is vital for operations such as similarity search, classification or clustering.
