What does Steganography primarily aim to achieve in information security?

Steganography primarily aims to achieve information confidentiality by concealing the existence of the data itself. Unlike encryption, which transforms data into an unreadable format that requires a key for decryption, steganography allows information to be hidden within other seemingly innocuous files, such as images, audio files, or even text documents. This technique ensures that not only the content of the secret message remains confidential, but also its very presence is disguised.

While data compression, data redundancy, and data integrity are important concepts within information security, they do not align with the primary goal of steganography. Data compression reduces the size of data to save space, redundancies involve the duplication of information for reliability, and data integrity ensures that information remains accurate and unaltered over time. These aspects do not focus on hiding the existence of data, which is the essence of steganography's commitment to maintaining confidentiality.
