Privacy

An AI principle that AI systems collect, use, share, and store personal data in a way that minimizes data collection, protects individuals' identities and sensitive information, and complies with laws and user expectations

The Explain card

Plain English
Privacy, as an AI principle, means systems collect only the personal data they need, protect people's identities and sensitive details, and handle data in ways that match the law and what users reasonably expect.
Example
A voice assistant could store every recording forever "in case it helps training". A privacy-respecting design keeps audio only as long as needed, strips identifiers before any training use, and lets users delete their history.
Why it matters
Models remember more than people think. Over-collection creates a larger breach surface, and memorised personal data can resurface in outputs. Minimising what goes in reduces what can come out.
Hook
Privacy in AI is data minimisation with manners: collect less, protect more, surprise no one.

Word knowledge

How the word is built, where it came from, and what it sits beside in memory.

In a sentence

The training pipeline runs a privacy scan that redacts names and account numbers from the call transcripts before they enter the feature store.

How it is built
  • priv- root one's own, set apart
  • -acy suffix state or quality
Where it came from
Origin
Middle English privacie, from Anglo-French privace and Medieval Latin privatia, from Latin privatus, set apart, from privus, one's own
Entered the language
15th century
What changed
Middle English used it for secrecy and a secluded place. Around 1600 it named withdrawal from observation. By 1814 it named freedom from intrusion. In 1890 it entered law as a right against public disclosure, and computing later used it for control of personal records.
How it is spelled
Pattern
-ate adjectives form nouns in -acy: private becomes privacy
Pattern
c before y spells /s/, as in policy and agency
Breaks the pattern
American speech keeps the long /aɪ/ of private; traditional British speech shortens the first vowel to /ɪ/, so one spelling has two sounds
