Abstract
A system can be designed that shares transaction data across different organizations while preserving data privacy and anonymizing the source organization. Organizations can enter into an agreement to share transaction data with each other through a trusted data sharing system. The organizations can input user records that include primary and secondary explicit user identifiers into the data sharing system. The data sharing system can correlate explicit user identifiers of a user across organizations via an internal identifier without exposing explicit user identifiers. The data sharing system comprises a data anonymizer agent for each sharing organization. A data anonymizer agent selectively applies anonymization filters to quasi-identifiers in the transaction data based on quasi-identifier type to extend data privacy protection measures to quasi-identifiers without drastically reducing or eradicating the utility of the quasi-identifiers.
