CAPTCHA ने काम करना क्यों बंद कर दिया
कमर्शियल CAPTCHA-सॉल्वर फ़ार्म hCaptcha और reCAPTCHA Enterprise को कुछ सेंट के लिए क्लियर कर देते हैं। पैसिव लाइवनेस कुछ ऐसा मांगता है जो किसी स्क्रिप्ट के पास नहीं होता, एक असली इंसान एक असली कैमरे के सामने। $0.10 प्रति गेट, दो सेकंड से कम, हर महीने 500 मुफ्त।
आप जो चेक चाहते हैं उन्हें चुनें, ID, लाइवनेस, फेस मैच, सैंक्शंस, एड्रेस, उम्र, फ़ोन, ईमेल, कस्टम प्रश्न। उन्हें डैशबोर्ड में एक फ़्लो में ड्रैग करें, या उसी फ़्लो को हमारे API पर पोस्ट करें। शर्तों पर ब्रांच करें, A/B टेस्ट चलाएं, किसी कोड की आवश्यकता नहीं।

Bots cannot pass Passive Liveness because they have no face to present to the camera. One API call. One signed webhook. One decision.
WHY THIS SHAPE
- Bots scale because they cost nothing per attempt. CAPTCHA stops the dumbest ones but commercial solver farms beat hCaptcha and reCAPTCHA Enterprise at fractions of a cent per solve.
- Passive Liveness asks for something a script does not have: a live human face in front of a real camera. The model decides on one frame, in under two seconds, with no user interaction beyond "hold still".
- $0.10 per check (Passive Liveness module). 500 verifications free every month. Combine with $0.03 IP / device pre-screen to keep the camera off the obvious bots and the budget on real candidates.
PRE-REQUISITES
- Production API key from https://business.didit.me (sandbox key in 60 seconds, no credit card).
- A webhook endpoint with HMAC SHA-256 verification of the X-Signature-V2 header using your webhook secret.
- A Workflow Builder workflow containing the Passive Liveness module — optionally Device & IP Analysis pre-step.
- The high-value action wrapped in a server-side gate that defaults to BLOCK and only unblocks on a verified webhook with status: Approved.
STEP 1 — (Optional) Cheap IP / device pre-screen
Before opening a camera, score the network with Device & IP Analysis ($0.03 / call, under 100ms).
If the score is low and no datacenter / VPN / scripted-user-agent flags fire, run Step 2.
If the score is high or any of those flags fire, skip the liveness call and decline up-front — this saves the camera budget for plausible humans.
STEP 2 — Open a Passive Liveness session
POST https://verification.didit.me/v3/session/
Headers:
x-api-key: <your api key>
Content-Type: application/json
Body:
{
"workflow_id": "<wf id with the Passive Liveness module>",
"vendor_data": "<your action / user id, max 256 chars>",
"callback": "https://<your-app>/bot-gate/callback",
"metadata": {
"surface": "signup_form",
"action_id": "<your internal reference>"
}
}
Response: 201 Created with a hosted session URL. Redirect inline (web) or open in a Software Development Kit (SDK) webview (mobile). The action stays BLOCKED on your side until the signed webhook lands.
STEP 3 — Read the signed webhook
Didit POSTs the verdict. Verify X-Signature-V2 (HMAC SHA-256 of the raw body using your webhook secret) BEFORE reading the JSON.
Payload (excerpted):
{
"session_id": "<uuid>",
"vendor_data": "<your action / user id>",
"status": "Approved",
"liveness": { "status": "Approved" }
}
Session status enum (exact case, Title Case With Spaces): Approved | Declined | In Review | Resubmitted | Expired | Not Finished | Kyc Expired | Abandoned.
STEP 4 — Branch the action
Approved → allow the sign-up / claim / submission.
Declined → block the action. Log liveness warnings (image-only / virtual-cam / replay / deepfake) and throttle the source IP.
Not Finished → invite the user to retry with a fresh session URL.
Expired → session timed out. Resend the link.
Abandoned → the user closed the flow before completing. Resend the link.
STEP 5 — (Optional) Replay Reusable Know Your Customer (KYC) for known humans
If a user has previously completed a Didit-verified session, a fresh liveness check is not required for re-entry — they can replay their verified credential at no cost via Didit Reusable KYC. Use the user's existing session_id to confirm enrollment and skip Step 2. Free forever.
WEBHOOK EVENT NAMES
- Sessions: standard session webhook. One endpoint, status field tells you where in the lifecycle.
- Verify X-Signature-V2 (HMAC SHA-256) on every payload.
WHAT GETS BLOCKED
- Headless Chrome with scripted form submission
- Browser-automation farms (Puppeteer, Playwright, Selenium)
- Image-only submissions (no camera attached)
- Virtual-camera AI face injectors
- Pre-recorded screen replays
- Print or paper attacks
- Silicone / latex masks
- AI-generated deepfake faces
All independently tested at iBeta and certified at Level 1 Presentation Attack Detection (PAD) against the full ISO/IEC 30107-3 catalogue. Re-tested every year.
CONSTRAINTS
- Session statuses use Title Case With Spaces. Never use UPPER_SNAKE_CASE for session verdicts — that's the Transactions API.
- Default to BLOCK on the server. Only unblock when the verified webhook says Approved.
- 200+ fraud signals are evaluated on every session at no extra cost — read them off the decision payload, don't re-query.

Didit is infrastructure for identity and fraud, the platform we wished existed when we were building products ourselves: open, flexible, and developer-friendly, so it works as a real part of your stack instead of a black box you integrate around.
One API covers verifying people (KYC, know your customer), verifying businesses (KYB, know your business), screening crypto wallets (KYT, know your transaction), and monitoring transactions in real time, on a stack built to be:
The footprint underneath: 14,000+ document types in 48+ languages, 1,000+ data sources, and 200+ fraud signals on every session. The Didit infrastructure dynamically learns from every session and gets better every day.
Anything that submits a form, claims a payout, posts a comment, or buys a ticket without a real human in the loop. Common shapes:
The defining trait is the same: nobody is looking at the screen, so nobody is in front of the camera.
CAPTCHA solver farms beat hCaptcha and reCAPTCHA Enterprise for fractions of a cent per solve. The economics flipped years ago, a 1,000-account attack costs the attacker less than your monthly Software-as-a-Service (SaaS) bill for the CAPTCHA itself.
The deeper problem is that CAPTCHA tests a skill (image recognition, character recognition, click patterns) that machines now do better than humans. A bot-gate has to test something machines do not have. A live human face in front of a real camera is exactly that.
The full flow normally takes under 30 seconds end-to-end, pick up the ID, snap the document, snap the selfie, done. That is the fastest in the market. Legacy KYC providers usually take more than 90 seconds for the same flow.
On the back end, Didit returns the result in under two seconds at p99, measured from the moment the user finishes the selfie to the moment your webhook fires. Mobile capture is tuned for slow phones and slow networks: progressive image compression, lazy software development kit load, and a one-tap hand-off from desktop to phone via QR code if the user starts on web.
Every common bot vector:
All caught at the Passive Liveness layer. Nothing for the bot to feed in.
Every session lands on one of seven clear statuses, so your code always knows what to do:
Approved, every check passed. Move the user forward.Declined, one or more checks failed. You can allow the user to resubmit the specific failed step (for example, re-take the selfie) without re-running the whole flow.In Review, flagged for compliance review. Open the case in the console, see every signal, decide approve or decline.In Progress, user is mid-flow.Not Started, link sent, user has not opened it yet. Send a reminder if it sits too long.Abandoned, user opened the link but did not finish in time. Re-engage or expire.Expired, the session link aged out. Create a new session.A signed webhook fires on every status change, so your database always stays in sync. Abandoned and declined sessions are free.
Production data is processed and stored in the European Union by default, on Amazon Web Services. Enterprise contracts can request alternative regions for jurisdictions whose regulators require it.
Encryption everywhere. AES-256 at rest across every database, object store, and backup. Transport Layer Security 1.3 in transit on every API call, webhook, and Business Console session. Biometric data is encrypted under a separate Customer Master Key.
Retention is yours to control. Default retention is indefinite (unlimited) unless you configure shorter, between 30 days and 10 years per application, and you can delete any individual session at any time from the dashboard or the API.
Certifications: SOC 2 Type 1 (Type 2 audit in progress), ISO/IEC 27001:2022, iBeta Level 1 PAD, and a public attestation from Spain''s Tesoro / SEPBLAC / CNMV that Didit''s remote identity verification is safer than verifying someone in person. Full report at /security-compliance.
Didit ships compliant by default for the regulators that matter to identity infrastructure:
Detailed memo, every certificate, every regulator letter: /security-compliance.
Three integration paths, pick whichever fits your stack:
Same dashboard, same billing, same pay-per-success price for all three. Step-by-step guide at docs.didit.me/integration/integration-prompt.
No. Users who have already passed a Didit-verified session can replay the credential at no cost via Reusable KYC, free forever. Look up the user's prior session_id; if the credential is valid, skip the live gate.
That keeps the friction (and the cost) on traffic you have never seen before. Returning humans pass instantly.
Two line items:
500 verifications free every month on every account, most teams sit inside the free tier for weeks. Returning users via Reusable KYC are free forever. No minimums, no annual commitment, no per-seat pricing.
