#15
What is the difference between steganography and cryptography?
Steganography hides the existence of the message, while cryptography hides the content of the message
Steganography uses encryption algorithms, while cryptography hides the message in images
Steganography encrypts messages, while cryptography hides the message in digital noise
There is no difference between steganography and cryptography
