The type of data registered might include extended caches of customer namesand account numbers, credit card numbers, patient records, or any other type of structured data.Up to 300 million records can be registered and tracked as they are moved. In addition, data that hasbeen identified can be associated with a rule to provide long‐term protection.The data retrieved using this method matches specific data values, not just patterns that describe thedata, and fine distinctions can be made between matches. For example, customer credit card numbersmight be reported as privacy violations, but an employee's own credit card number can be defined asan exception and ignored.The same mechanisms that support registration of flat files also support registration of databaserecords. For example, the signatures produced by data matching are stored in a factory defaultconcept, DBReg, which collects structured data in the form of comma‐separated values of exportedcolumns (fields) found in databases.The DocReg concept performs the same function for documents.McAfee Data Loss Prevention 9.2.2 Product Guide 79
