Anonymous Sensed Data Reporting

Computer Engineering

We are proposing an efficient anonymous data reporting protocol for participatory sensing. It provides strong 74privacy protection, data accuracy and generality. The protocol consists of two stages, namely message submission and encryption. In the message submission stage, each participant transmits a sensed data to the SQL server. The database maintain all records like smartphones IMEI number, smartphone identity name with sensed data from the sensors. It maintain those data but only application server has access to the database. In the Encryption phase, as per the request from the end user the Application Server will send the requested data but in encrypted format, which also not includes any identity information of the participants who sends those data. The encoded data to the End user do not contain any identity information, in such a way that the application server cannot link a data to a specific participant. With such a data reporting protocol, the link between the data and the participants is broken, and as a result, participant’s privacy is protected.
