Answer Description

Salting introduces random data to each password before hashing, which ensures that identical passwords result in different hash values. This protects against rainbow table attacks that rely on precomputed hash values. Steganography hides data within other files, obfuscation makes data difficult to interpret, and tokenization replaces sensitive data with non-sensitive equivalents. These methods do not prevent rainbow table attacks on passwords.
