The KYC Authentication Latency Barrier

In Indian fintech sectors, quick onboarding KYC verification is crucial. Heavy facial recognition libraries cause browser-side timeouts and user drops on lower-end devices.

Engineering A Light Liveness Check

By compiling our custom facial landmark extraction module into a highly optimized WASM package and utilizing local hardware acceleration, we dropped payload sizes down to 840KB and enabled dynamic client-side liveness checks.

import { FacialIdentitySDK } from '@deepskylabs/facial-identity-sdk';

const sdk = new FacialIdentitySDK({
  apiKey: "ds_live_8931289a",
  detectionMode: "liveness-active"
});

sdk.onFaceVerified((result) => {
  console.log("Onboard verification payload:", result.authToken);
});
