CODE ANALYSIS FOR PROVIDING DATA PRIVACY IN ETL SYSTEMS

In an approach for providing data privacy in information integration systems, a method performed during compilation of an information integration job receives information regarding a data flow structure of the job to be executed, said data flow structure comprising at least one source system, one or more target entities, and at least one operator for modifying output data provided by the source system. The method determines data exit points at which output data are provided to the target entities and determines at least one non-trusted target entity. The method determines, for each non-trusted target entity, if at least one data field included in the output data provided to the non-trusted target entity is classified as sensitive information, and, if so, modifies the information integration job by including a masking operator directly before a data exit point associated with the non-trusted target entity in order to mask said sensitive information.
