Steganography - PowerPoint PPT Presentation


Steganography: Hiding Secrets in Plain Sight

Steganography, the art and science of concealing secret messages in such a way that no one suspects their existence, differs from cryptography in its goal of avoiding suspicion rather than rendering the message unreadable. This method involves hiding messages within seemingly innocuous data, such as
