Abstract
Systems and methods for preprocessing data to facilitate DLP pattern matching are provided. An input string is received by a Data Leak Prevention (DLP) system. The input string is converted by the DLP system into a fixed string pattern. The conversion is performed based on one or more of multiple class definitions, including a digit class, a letter class and a symbol class. A determination is then made by the DLP system regarding whether the input string contains potential sensitive data to which a full-match is to be applied by matching the fixed string pattern against one or more stored target strings representative of sensitive data.
