ABSTRACT:
A method and system for data masking a series of interrelated data records is disclosed. A lockable translation matrix repository resource is provided to contain both masked data as well as appropriate key information that provides links between respective copies of respective interlinked databases and maintains the data integrity of masking data inserted therein. Records are masked on a column by column or table by table basis. Records for which masking data is already in the repository are masked by making use of such data, while remaining records are segregated, masked and the masking data updated to the repository. Preferably a backup copy of the masked data records is stored in the repository to permit de-masking of the data records at a later stage. Pivot tables are applied where keys do not match exactly but still exhibit a one-to-one relationship.
