1. Omitting biometric disclosure in privacy notices
The mistake: Many operators add Persona without updating their privacy policy to explicitly name facial biometric collection, retention periods, or deletion rights. They rely on generic "identity verification" language.
Why it happens with Persona: Persona's biometric data (liveness selfies, face matching) is not immediately obvious to non-technical founders—they focus on the ID document upload. But GDPR Articles 13–14, CCPA Section 1798.100, and BIPA Section 15 all require *specific* disclosure of biometric collection before or at the point of collection.
Consequence: GDPR DPAs can issue substantial fines (Article 83); CCPA/CPRA violations carry statutory damages ($100–$750/consumer/incident). Illinois regulators have pursued enforcement for BIPA violations without explicit consent. Regulators also treat vague notices as bad-faith indicators in larger investigations.
2. Missing or outdated Data Processing Agreement
The mistake: Operators deploy Persona without executing a written DPA or fail to update an existing DPA when workflows change (e.g., adding SSN collection, expanding to new jurisdictions).
Why it happens with Persona: Persona is a SaaS point-and-click integration; founders assume "privacy terms are covered" by Persona's standard terms. But GDPR Article 28 mandates a *specific, written* contract governing processor obligations, subprocessor authorization, data subject rights support, deletion/return timelines, and audit rights—Persona's privacy policy alone does not constitute a DPA.
Consequence: GDPR non-compliance (no contractual safeguards) exposes you to supervisory authority action and can void your lawful basis defense. Processors can also refuse to process without a DPA in place.
3. Collecting biometric/SSN data without jurisdiction-specific consent
The mistake: Operators deploy Persona globally or in high-regulation jurisdictions (EU, California, Illinois) without configuring separate consent flows. They treat consent as binary (yes/no) rather than layered by data type.
Why it happens with Persona: Persona's UI is streamlined for KYC speed; it doesn't prompt differently for biometric vs. ID document vs. SSN. Founders assume "consent to verify identity" covers all three, but BIPA requires explicit consent *for biometric collection specifically*, GDPR Article 9 requires explicit consent or a lawful Article 9(2) derogation, and CCPA requires separate notice of SSN collection as a sensitive category.
Consequence: Regulators flag consent failures as structural non-compliance. BIPA cases have resulted in class-action settlements (e.g., Clearview AI). GDPR fines scale up when consent is absent for special-category data. CCPA enforcement prioritizes SSN collection without compliant disclosures.
