Zusammenfassung:	User rating data may be received at a correlation engine through a network. The user rating data may include ratings generated by a plurality of users for a plurality of items. Correlation data may be generated from the received user rating data by the correlation engine. The correlation data may identify correlations between the items based on the user generated ratings. Noise may be generated by the correlation engine, and the generated noise may be added to the generated correlation data by the correlation engine to provide differential privacy protection to the user rating data.
