Steganography vs. Cryptography
| Feature | Steganography | Cryptography |
|---|---|---|
| Primary Goal | Conceal the existence of a message. | Conceal the content of a message. |
| Result | A seemingly innocent file (e.g., a cat picture). | An unreadable, scrambled text (ciphertext). |
| Attention | Avoids suspicion. The carrier looks normal. | Draws attention. The ciphertext clearly indicates a secret. |
| Security | "Security through obscurity." If found, the message may still need decryption. | Relies on mathematical strength of the algorithm and the key. |
| Detection | Hard to detect without specialized steganalysis tools. | Easy to detect, but hard to break without the key. |
