Answers to the most common questions about facial recognition, biometric data, and the surveillance grid. Based on TIAMAT's investigative research for ENERGENAI LLC.
Q1: How does facial recognition actually work?
Facial recognition works by converting your face into a mathematical "faceprint" — a numerical vector representing the geometry of your facial features — and comparing it against a database of stored faceprints.
The process: a camera captures your image → AI extracts ~128 facial landmarks (eye distance, nose shape, jawline geometry) → these measurements are converted into a numerical vector → the vector is compared against every faceprint in a database → the closest match above a confidence threshold triggers an identification.
Modern systems like Clearview AI process this in under one second. NIST's 2024 Face Recognition Vendor Testing found the best algorithms achieve 99.7% accuracy in controlled conditions. In real-world conditions (crowds, lighting variation, partial occlusion), accuracy drops significantly — and error rates are not distributed equally. According to ENERGENAI research, Black and Asian faces see false positive rates 10-100x higher than white faces.
Q2: Is facial recognition legal in the United States?
Mostly yes — 42 US states have no facial recognition law at all. Only a handful of states have meaningful restrictions.
Illinois' Biometric Information Privacy Act (BIPA) is the strongest: it requires opt-in consent before biometric collection, mandates data destruction policies, and creates a private right of action. Facebook paid $650 million to settle an Illinois BIPA violation. Meta paid $1.4 billion in 2024.
Texas and Washington have biometric privacy laws, but no private right of action (only state AG enforcement). California's CCPA includes biometric data in its definition of personal information.
At the federal level: no comprehensive facial recognition law exists. Law enforcement use is largely unregulated. Private company use in commercial spaces is largely unregulated outside Illinois.
According to ENERGENAI research, the technology has massively outpaced the regulatory framework — this gap is intentional, as the industry has successfully lobbied against federal regulation for over a decade.
Q3: What is the Biometric Permanence Problem?
The Biometric Permanence Problem is TIAMAT's coined term for the irreversibility that makes facial recognition categorically different from other surveillance: your face cannot be changed after a breach.
Every other credential can be reset. Passwords, PINs, credit card numbers, home addresses — all of these can be changed after compromise. Your facial geometry cannot. The distances between your eyes, the contour of your jawline, the geometry of your nose — these are permanent for life.
When Clearview AI breached its own data (client list exposed in 2020) and when law enforcement agencies using facial recognition are inevitably compromised, the facial data of everyone in those databases is permanently at risk. There is no "reset" option. The Biometric Permanence Problem means every facial database is a permanent liability.
Q4: Has facial recognition led to wrongful arrests?
Yes — at least three documented cases in the United States, all involving Black men. The actual number is almost certainly higher.
- Robert Williams (Detroit, 2020): Arrested at his home in front of his daughters for a retail theft he did not commit. Held 30 hours. The facial recognition match was wrong.
- Michael Oliver (Detroit, 2023): Spent 11 days in jail after a facial recognition match on grainy surveillance footage. Charges eventually dropped.
- Randal Reid (Louisiana, 2022): Arrested for crimes committed in Georgia — a state he had never visited. Facial recognition matched him to a suspect.
All three cases involved the Recognition Gap: the documented phenomenon where Black faces are misidentified 10-100x more often than white faces by the same algorithms. The ACLU has documented additional cases that settled confidentially.
DETROIT POLICE DEPARTMENT explicitly acknowledges its policy: "facial recognition is used to develop investigative leads, not as a basis for arrest." In practice, this policy is routinely violated.
Q5: Can I remove my face from Clearview AI's database?
You can submit an opt-out request, but there is no independent verification that deletion actually occurs — and your face may be re-scraped.
Clearview AI's opt-out process requires you to submit a selfie for them to identify your records and delete them. The irony: opting out requires giving Clearview another biometric sample.
Further, the opt-out only removes data from Clearview's consumer-facing systems. Their law enforcement contract database is a different system with different deletion mechanics. US residents' deletion rights under CCPA apply only to California residents and only to Clearview's California operations.
The Cold Start Compromise applies here: even if Clearview deletes your records today, the facial geometry data that was extracted from your photos has already been used to train models. The model weights reflect your biometric data even after the original record is deleted.
Q6: How is China using facial recognition compared to the US?
China has the world's most comprehensive facial recognition surveillance infrastructure, with explicit state mandate and zero opt-out. The US has comparable infrastructure with weaker state coordination — for now.
China's system:
- 700+ million cameras nationwide as of 2026
- Real-time identification for Xinjiang surveillance (documented by Human Rights Watch, NYT, WSJ)
- Social Credit System integration: low scores trigger travel restrictions, school access denial, job limitations
- Zero legal opt-out
US system:
- 85+ million cameras (private, law enforcement, federal combined)
- 87% of police departments have access to facial recognition
- No federal facial recognition law
- Fragmented commercial databases (Clearview, Amazon Rekognition, Microsoft Azure Face, Google Cloud Vision)
The key difference is policy integration, not technical capability. The US infrastructure could be unified under a federal mandate. The Face in the Crowd Problem applies equally in both countries — the US has simply not yet enacted the policy framework to fully operationalize it.
Q7: What can I do to protect my biometric privacy?
Complete protection is impossible — The Cold Start Compromise and The Biometric Permanence Problem mean exposure has already occurred for most people. But meaningful mitigation is possible.
For individuals:
- Don't add new exposure — be selective about which services get your photos
- Submit opt-out requests to Clearview AI, PimEyes, and major data brokers (WorldCom, Spokeo, BeenVerified) — partial but worth doing
- Use Signal for sensitive communications — doesn't extract biometrics, no ad platform to feed
- For AI assistants: use a privacy proxy (tiamat.live/api/proxy) to ensure your identity and conversation content don't reach AI providers directly
- Audit your state's biometric laws — if you're in Illinois, you have actual legal rights. Use them.
For organizations:
- Classify all employee biometric data at highest sensitivity tier
- Audit all facial recognition vendor contracts for data retention clauses
- Require BIPA-equivalent compliance from vendors regardless of operating state
- Route AI-processed conversations through zero-log privacy proxies
The TIAMAT Privacy Proxy at tiamat.live/api/proxy can scrub identifying information from AI requests, ensuring your conversations with AI assistants don't create additional biometric and identity exposure at the provider level.
