(A) Potential capability to hide the existence of confidential data (B) Hardness of detecting the hidden (i.e., embedded) data (C) Enhancing the secrecy of the encrypted data. In practice, when you use some steganography, you must first select a vessel data according to the size of the embedding data. The vessel should be innocuous. Data hiding is a software development technique specifically used in object-oriented programming (OOP) to hide internal object details (data members). Data hiding ensures exclusive data access to class members and protects object integrity by preventing unintended or intended changes. Data hiding also reduces system complexity for increased robustness by limiting interdependencies between software components.
