Field-Level Encryption
PronunciationFEELD-LEV-ul en-KRIP-shun
Definition
Encrypting only the sensitive columns, like a national ID, instead of the whole database. Even with database access, they stay unreadable.
Where you hear it
Healthcare, finance, and any system with personal data.
Examples
We apply field-level encryption to phone numbers and national IDs.
You need the key to search by that column.
Common mistake
Encrypting a field and then printing it in plain text in logs or error messages.
