Answer Description

Steganography involves hiding sensitive information within another file, such as embedding a secret message within an image or audio file. This makes the existence of the sensitive data less obvious to unauthorized users. Encryption transforms data into unreadable ciphertext, but the encrypted data is still noticeable and may attract attention. Hashing converts data into a fixed-size hash value, mainly for integrity verification, and is not reversible. Data masking replaces sensitive data with altered values but does not hide it within another file.
