Here’s your guide to the Data Defense Squad: Tools for Security Encryption: Scramble your data with a secret key for secure storage and transmission. Masking: Replace sensitive data with realistic but fictional substitutes to protect privacy. Steganography: Hide messages within other files, like images or audio, for secure communication. Encoding: Convert data into a different format for easier transfer and processing. Tokenization: Replace sensitive data with unique tokens to protect information during transactions. Pseudonymization: Safeguard personal identifiers by replacing them with pseudonyms, preserving privacy in data analysis. Hashing: Create a unique fingerprint for your data to detect tampering.
