Abstract
A method includes obtaining first text information in a first format, converting the first text information to an offset value from a base time in a second format, generating an encryption key, encrypting the offset value with the encryption key to produce an encrypted offset value in the second format, converting the encrypted offset value to second text information in the first format, and outputting the second text information as encrypted text corresponding to the first text information.
