You've downloaded a chat app, and before you can use it, it asks for two things most apps never do: a photo of your government ID and a live selfie of your face. If that gives you pause, good — that's the right instinct. You should think twice before handing your face and ID to any app.
So let's be specific about what actually happens when you verify on AirlockChat: what gets checked, what gets kept, and what gets thrown away. And let's clear up the fear underneath the question — because the kind of "face verification" used to prove you're real is the opposite of the face-scanning surveillance people are right to worry about.
The fear: "Isn't this the face-scanning the news warns about?"
When people hear "face scanning," they usually picture cameras in a railway station or mall quietly identifying everyone who walks past. That fear is justified — but that technology is facial recognition, and it is not what happens when you verify your identity.
Facial recognition is a 1:N (one-to-many) search. A camera captures a face in a crowd and compares it against a database of millions of people to answer the question "Who is this?" — usually without the person knowing or agreeing. It runs on mass data collection (faces often scraped from the internet), and in the wrong hands it enables tracking people without consent. When you're uneasy about "face technology," this is almost always the thing you're picturing. And you're right to be.
Verifying your identity to use an app is a completely different process.
What face verification actually is
Face verification is what your phone does when FaceID unlocks it, and what your banking app does when you open an account. It's a 1:1 (one-to-one) check that answers a much narrower question: "Are you the person on this ID?"
- You assert an identity — "I'm the person on this document."
- You take a live selfie.
- The system compares that selfie only against the photo on the ID you provided. Nothing else.
- It returns a yes or a no — same person, or not.
Two things make this the opposite of surveillance:
- It can't happen without you. There's no passive scan. You actively choose to verify, share your document, and take the selfie.
- There's no database search. Your face isn't checked against millions of strangers. It's compared to exactly one photo — the one on your own ID — and then the comparison is done.
This is verification used to protect you: it's what stops someone who stole your ID number from opening an account or building a profile in your name, because they don't have your face.
Step by step: what happens when you verify on AirlockChat
AirlockChat uses face verification — never face recognition. Here's the actual flow:
- You connect DigiLocker. You authenticate with DigiLocker, the government's official digital document wallet, to securely share a verified document (like an Aadhaar or Driving Licence). AirlockChat never sees your DigiLocker password.
- You take a live selfie inside the app.
- A 1:1 comparison runs between your selfie and the photo on your government document.
- If they match, you're verified. Your verified first name becomes your permanent display name — not a username you made up.
- The selfie's job is done. It's used for that one comparison at sign-up, not to build a searchable face database. AirlockChat has no way to scan a crowd and find you.
What AirlockChat actually keeps
This is the part that should put the original worry to rest. After verification, AirlockChat stores:
- Your verified first name.
- A masked version of your document number — the last 4 digits only.
That's it. AirlockChat does not keep your full Aadhaar number, your full document image, or your address, and it doesn't maintain a searchable database of faces. Data handling follows the Digital Personal Data Protection Act (DPDPA), and if you delete your account, your verification data is purged within 30 days.
In other words: you're not "giving an app your face." You're proving, once, that you're a real person — and almost nothing is retained afterward.
Why a chat app asks for this at all
For two decades, the internet ran on anonymity: anyone could make an account with any name and any photo. That's exactly what made fake profiles, romance scams, and impersonation so easy. When a platform tries to fix it, it has three choices:
- Do nothing — keep allowing anonymous accounts and react only after someone's been scammed. (Most social and messaging apps.)
- Mass surveillance — monitor everything everyone says with AI. (Destroys privacy, barely stops real scammers.)
- Verify once, at the door — make sure every user is a real, accountable person before they can message anyone, using privacy-preserving 1:1 verification.
AirlockChat chose the third. Verifying that the person holding the phone matches the government ID removes the anonymity scammers depend on — without building the surveillance database that face recognition would require. That's the whole point: everyone you talk to has cleared the same door you did.
Verification vs. recognition, side by side
| Face Verification (1:1) | Face Recognition (1:N) | |
|---|---|---|
| Question it answers | "Are you who you say you are?" | "Who is this person?" |
| What it compares | Your face to ONE ID you provided | Your face to MILLIONS in a database |
| Consent | Requires your active choice | Often passive, without your knowledge |
| Typical use | Unlocking phones, banking, proving identity | Public surveillance, tracking |
| Effect on privacy | Protects you from impersonation | Erodes privacy through mass tracking |
| Used by AirlockChat | Yes — once, at sign-up | No — never |
The bottom line
The unease you feel about "face scanning" is aimed at the right target — it's just aimed one category over. Recognition searches a crowd to figure out who you are, without asking. Verification asks your permission to confirm you're the real owner of one ID, then gets out of the way. AirlockChat uses only the second kind, keeps almost nothing, and uses it for a single purpose: so everyone on the other end of a conversation is a real, accountable person — not a scammer hiding behind a stolen photo.
