Difference between Steganography and Cryptography
Steganography and cryptography are critical components of network security. Network security has emerged as an essential part of today’s communication infrastructure. There was an urgent need for network security to protect confidentiality and data integrity. It protects the user against unauthorized access. Steganography hides communication traces, while cryptography uses encryption to make the message unreadable.
