A healthcare company needs to secure patients' medical records by replacing sensitive data with non-sensitive substitutes that retain the data's format and make it usable for processing but meaningless if intercepted. Which technique should the company implement to achieve this?
Encryption
Steganography
Data Masking
Tokenization
Tokenization replaces sensitive data with tokens that maintain the original data format, allowing the data to be processed while protecting the underlying sensitive information. If intercepted, these tokens are meaningless to unauthorized users. Data masking obscures data but may not preserve its usability for processing. Steganography involves concealing data within other files, which does not apply to this scenario. Encryption secures data by converting it into ciphertext, which typically must be decrypted before processing, potentially exposing sensitive data.
