        abstract = {Cryptography is a technique used to transmit data in a secured way using encryption and decryption. Encryption is the process of converting information from its original form (plain text) into an unintelligible form (cipher text).In Cryptography many traditional algorithms introduced to provide security to sensitive data but encrypted data changes its length and format. There is a requirement to change existing database schema. Format Preserving Encryption mechanism there is no need to change database schema. It is a way to encrypt data such that the cipher text has the same length and format as the plaintext.
This paper describes various techniques of FPE, Its pros and cons and survey done on these techniques. Finally it concludes by comparison of all techniques.
