Verification

Reliable confirmation that something is true or accurate.

Reach for it when naming the act of checking a claim, identity, or result against evidence

Independent verification finally resolved the dispute over the measurements.

• everyday

  checking

  plain language suits a routine review

  not when Checking may be casual and undocumented.

• everyday

  confirmation

  a prior expectation receives support

  not when Confirmation may rely on only one favorable check.

• professional

  authentication

  identity or genuine origin is at issue

  not when Authentication does not prove every associated claim.

• professional

  validation

  fitness for a purpose is systematically established

  not when Validation evaluates suitability, not identity.

• formal

  corroboration

  independent evidence supports an account

  not when Corroboration strengthens rather than conclusively proves.

• formal

  proof

  decisive evidence is genuinely available

  not when Proof overstates most practical verification.

• literary

  substantiation

  supporting material gives a claim firm basis

  not when Substantiation may stop short of direct testing.

• disproof
• assumption
• fabrication

• identity verification

  Identity verification used a private channel and retained no document copy.

• independent verification

  Independent verification found the reported total within one percent.

• verification process

  The verification process records both passes and unresolved questions.
