Abstract
A data security method including creating a token-including plaintext by including a predefined token into a plaintext, generating a cyphertext by encrypting the token-including plaintext using format-preserving encryption, generating a decrypted cyphertext by decrypting an input text, determining whether the decrypted cyphertext includes a first predefined token, if the decrypted cyphertext includes the first predefined token, recreating the plaintext by removing the first predefined token from the decrypted cyphertext, and if the decrypted cyphertext does not include the first predefined token, using the input text as the plaintext.
