DERIVING SIGNAL LOCATION INFORMATION AND REMOVING OTHER INFORMATION
The invention extends to methods, systems, and computer program products for deriving signal location information removing private information. A privacy infrastructure can apply data privacy operations to identified information prior to, during, or after any of signal ingestion, event detection, or event notification. A raw signal is ingested. A partially normalized signal is derived from the raw signal. A list of one or more geo cells where the raw signal potentially originated is accessed. A location annotation identifying a geo cell from among the one or more geo cells can be formulated. The partially normalized signal is annotated with the location annotation. In one aspect, deriving the partially normalized signal includes identifying information contained within the raw signal. At least one data privacy operation is applied to the identified information. The partially normalized signal is generated subsequent to applying the at least one data privacy operation.
