Retracted: Spatial Crowdsourcing Quality Control Model Based on K-Anonymity Location Privacy Protection and ELM Spammer Detection
At the request of the authors, the article titled “Spatial Crowdsourcing Quality Control Model Based on K-Anonymity Location Privacy Protection and ELM Spammer Detection”  has been retracted. The authors found in a recent experiment that a serious error was caused by the server hardware failure, so the paper was written based on incorrect data and there was a big deviation in the argument.
