Dana wants to protect data in a database without changing characteristics like the data length and type. What technique can she use to do this MOST effectively?

Tokenization is a method of safeguarding sensitive data by replacing it with tokens that maintain the same length and data type. This enables databases to handle the data in the same way as before tokenization, avoiding any compatibility issues with existing software. Encryption also offers data protection, but typically changes either the data length, the data type, or both. On the other hand, one-way hashing is not suitable for many situations where tokenization or encryption are needed to secure the data. Rotation, however, is not a security measure employed in this context.
