1. A computer-implemented method for providing data privacy in an information integration system, the method performing during compilation of an information integration job the steps of:

  • receiving information regarding a data flow structure of an information integration 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 at least one source system;

    determining a set of data exit points at which the output data are provided to the one or more target entities;

    determining at least one non-trusted target entity of the one or more target entities;

    determining, 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 at least one data field included in the output data provided to the non-trusted target entity is classified as sensitive information, modify 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.
