Novel trajectory data publishing method under differential privacy

作者：

Highlights：

• A new type of trajectory sequence structure-sequence R-tree (SR-tree) is proposed.

• A method for publishing moving object trajectory data satisfying differential privacy is proposed.

• Non-location sensitive information associated attacks are avoided.

• The published data is processed consistently to improve the accuracy.
