Format-preserving encryption (FPE) is a technique for desensitizing data that is about to become an ANSI standard, joining tokenization, which is already entering its second generation.


  • Ovum sees a growing need for these technologies, which hide data from prying eyes yet leave it usable by processes downstream from the desensitization.

  • Understand the growing need for methods of obfuscating or desensitizing data while leaving it usable in downstream processes.
  • Understand the different means of achieving this goal, such as tokenization and FPE.

Key questions answered

  • What is the difference between FPE and tokenization and what are the pros and cons of each?
  • How has tokenization evolved from its first to its second generation?
