Did You Know?

Steganography is a word that was resurrected after being in disuse for almost 150 years! It was put to rest in the early 1800s, labeled an archaic synonym of "cryptography" by dictionary makers, but was brought back to life in the 1980s as a word for a type of digital cryptography. There is nothing cryptic about the word's origin; it is based on the Greek word steganos, meaning "covered" or "reticent."

Origin and Etymology of steganography

New Latin steganographia, from Greek steganos covered, reticent (from stegein to cover) + Latin -graphia -graphy — more at thatch


First Known Use: 1985
