How this fits into existing government websites

example-govportal.gov.in

VerifyOnce isn't a separate app — it's a feature any government portal can add to their own login page, similar to 'Sign in with Google.'

Why doesn't this already exist?

DigiLocker already offers document-sharing APIs, but adoption is optional per department. The real bottleneck isn't technology — it's adoption incentives and unresolved liability questions (who's responsible if shared data is wrong). VerifyOnce assumes this trust-sharing layer as a default, not an opt-in afterthought. Closing this gap fully requires two things: (1) formal DigiLocker/API Setu partnership for real issuer trust, and (2) fuzzy-matching fraud detection beyond exact-match checks — both are our next milestones, not final claims.

View verification proof (Technical detail)
Signed and verified using the Web Crypto API (ECDSA P-256) — real cryptography running in your browser. In production, signing would happen server-side via HSM/KMS.
Note: In this demo, VerifyOnce acts as both the issuer and verifier for simplicity. In a real deployment, the issuing authority would be a registered entity (e.g., DigiLocker/MeitY) with a publicly verifiable key, checked against a trust registry — not self-issued. In production, this would follow the W3C Verifiable Credentials standard, using Decentralized Identifiers (DIDs) and a public trust registry maintained by the issuing authority (e.g., DigiLocker/MeitY).

Tamper Detection Demonstration
Simulate an attacker editing the citizen ID or payload in localStorage. Because ECDSA signatures are cryptographically bound to the data, any alteration causes crypto.subtle.verify() to genuinely fail across consuming portals.
