4 Steps from Draft to Enforceable Agreement
Inscriben handles the full handshake between your business, the signer, and Protean's certified ESP infrastructure.
Upload & Configure Envelope
Upload your PDF agreement and select Aadhaar eSign. Add one or multiple signatories with their legal names and email/phone numbers.
Secure Signer Link Delivery
The signer receives an encrypted, time-limited signing link via SMS and email. They review the full contract before initiating the government signing handshake.
UIDAI OTP Authentication
The signer enters their Aadhaar number directly on Protean's certified ESP gateway and authenticates via an instant OTP sent to their UIDAI-registered mobile.
Cryptographic Seal & Visual Stamp
Protean issues an on-the-fly digital certificate. Inscriben bakes a customized visual corporate seal, dynamic QR code, and PAdES PKCS#7 certificate into the PDF.
Why Indian Courts Presume Authenticity
Unlike standard unverified digital signatures that require proving authenticity in trial, Aadhaar eSign carries explicit statutory backing.
IT Act 2000 Section 3A & Section 5
Recognized as a legally valid electronic signature technique under the Second Schedule. Holds the exact same statutory validity as handwritten wet-ink signatures.
BSA 2023 Section 86 (IEA 85B)
Carries statutory presumption of authenticity in Indian courts: the judiciary legally presumes the contract was signed by the Aadhaar holder without requiring trial proof.
CCA & UIDAI Licensed Framework
Operated through licensed Certifying Authorities (CAs) and certified eSign Service Providers (ESPs) under strict Controller of Certifying Authorities guidelines.
Zero Raw Aadhaar Storage
Complete privacy protection. Only masked numbers (XXXX-XXXX-4589) and unique Protean audit transaction IDs are recorded in compliance with UIDAI regulations.
Visual Corporate Stamp + Cryptographic X.509
While other providers only inject an unstyled text block, Inscriben bakes a customized corporate visual seal, timestamp badge, signer details, and dynamic QR verification code directly into the document canvas.
