parity
This glossary entry explains parity for AI governance and model risk programs. The sections below summarize what the term means in plain language, why chief AI officers and cross-functional committees track it, where teams often get confused, and—when you are signed in—how it shows up across major industries and in expectations tied to the EU AI Act and NIST AI RMF.

What It Means
Parity is a simple error-detection method that adds an extra bit to data to check if information has been corrupted during transmission or storage. Think of it like a basic checksum that can catch simple mistakes when data is moved from one place to another.
Why Chief AI Officers Care
While parity provides basic data integrity checking, it can only detect single-bit errors and offers no protection against sophisticated cyber attacks or intentional data manipulation, making it insufficient for modern security requirements.
Real-World Example
An older email server uses parity bits to check if messages were corrupted during transmission between servers, but this wouldn't detect if a hacker deliberately modified the email content using advanced techniques.
Common Confusion
Executives often think parity provides comprehensive data protection and security, when it's actually just a basic error-detection tool that can't prevent malicious attacks or recover corrupted data.
