Choosing a document verification partner is a significant decision. This page helps procurement and operations teams understand how TamperCheck compares to Persona - on pricing, privacy posture, and what it actually takes to get started.

When to choose TamperCheck
- You already have an onboarding flow and just need to add forensic checks to file uploads (like pay stubs or invoices) that standard IDV doesn't cover.
- You want managed AI inference and transparent $/doc pricing without migrating to a new identity platform.
- You need zero data retention for sensitive document processing.
When to choose Persona
- You need to build an end-to-end KYC/KYB onboarding flow from scratch, including UI, liveness checks, and database verifications.
- You want a manual review dashboard where your agents can inspect flagged users and documents.
Identity platform vs. specialist document forensics
Persona orchestrates identity journeys: ask a user for their ID, take a selfie, check a government database, route the failures to a human reviewer. TamperCheck does none of that - and Persona does none of what TamperCheck does. Once the document is in the queue, the question is whether the file itself was altered, and that is a forensic question, not an orchestration one.
TamperCheck is a specialist document forensics service. If you have a backend process that receives a PDF or image and you need to know if it was manipulated in Photoshop or generated by AI, TamperCheck gives you a definitive answer in about a minute. Many companies use Persona for user onboarding and TamperCheck for ongoing document submissions.
TamperCheck vs Persona: common questions
Is TamperCheck an alternative to Persona?
For document forensics, yes; for identity orchestration, no. Persona builds and routes verification journeys. TamperCheck answers a single technical question about a file - was it edited in Photoshop, or generated by AI, and which field changed - which is the part an orchestration layer routes to but does not itself perform.
Can Persona and TamperCheck run together?
Yes. A common pattern is Persona for user onboarding and TamperCheck for the documents that arrive afterwards - income proofs, invoices, certificates - called as a single step inside a Persona workflow so the forensic verdict lands in the same review queue your agents already use.
What does TamperCheck return that a review dashboard does not?
The reason. A dashboard shows an analyst the document; TamperCheck tells them which field is inconsistent with the rest of the page and why - font weight, edge sharpness, recompression history, arithmetic that does not reconcile - so the decision can be defended later without forensic expertise on the team.
