Which field derives its name from Greek words kryptos and graphia and involves converting data into scrambled code?

• A. Biometrics
• B. Plain text
• C. Cryptography
• D. Encryption

Answer: (C)

Cryptography is the study and practice of securing information by transforming it into unreadable form and then back again using keys. The term comes from Greek kryptos meaning hidden or secret and graphia meaning writing. The idea of converting data into scrambled code describes encryption, a central technique within cryptography. So the field named for those Greek roots is cryptography; encryption is the process used within that field to conceal information. Other options don’t name the field: biometrics uses physical traits for identification, and plain text refers to data in readable form.
