Integrity

Integrity establishes whether evidence or artifacts have changed outside the expected process.

Common integrity mechanisms include:

• cryptographic hashes
• signatures
• chained records
• manifests
• protected evidence boundaries

Integrity is not authenticity by itself

A hash can show that content changed.

It does not automatically prove who produced the content or whether the original content was trustworthy.

Verification systems should therefore distinguish integrity from provenance, identity and semantic correctness.
