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.

Claim (Index 12):
The non-transitory computer-readable storage medium of  claim 11 , wherein said converting, by the DLP module, the input string into a fixed string pattern comprises:\n sequentially processing each character within the input string, including:\n when at least two consecutive characters are identified that are associated with a class definition of the plurality of class definitions, replacing a first character of the at least two consecutive characters with a first replacement character within the class definition and replacing a second character of the at least two consecutive characters with a second replacement character within the class definition, wherein the second replacement character comprises a character sequentially following the first replacement character within the class definition; \n when an isolated character is identified that is associated with the class definition and the isolated character is not part of a group of multiple consecutive characters associated with the class definition, replacing the isolated character with a single replacement character from the class definition; and \n when the character represents whitespace or a symbol, skipping the character or replacing the character with a corresponding predefined symbol.
