Abstract
The method for obfuscating a string includes selecting, by a processor, a first string of a first portion of input plain text that does not match a predefined text signature from a set of two or more text signatures. In addition, the method may include identifying, by the processor, a historical string that is similar to the first string from a set of two or more historical strings stored. Further, the method may include generating a first text signature, by the processor, by updating a text signature in the set of two or more text signatures that matches the identified historical string. The first text signature defines a pattern that matches the first string and the identified historical string. The first text signature, by the processor, may be saved to the set of text signatures in the memory.
