Digital Signature Certificates (DSC) Tokens:
What they are: Hardware devices storing a user's digital certificate issued by authorized Certifying Authorities.
How they work: Use cryptography to ensure authenticity and integrity.
Use cases: E-tendering, tax filing, company registrations, legal agreements.
Electronic Stamps:
What they are: Digital marks or seals affixed to electronic documents.
How they work: Can involve various technologies, often with cryptographic elements.
Use cases: Document approvals, official document stamping.
Aadhaar-Based Signing:
What they are: Leverages Aadhaar's biometric identification system for signing.
How they work: Uses Aadhaar number with biometric or OTP authentication.
Use cases: Online banking, government services, digital onboarding.
Choosing the Right Digital Signature
The best choice depends on your specific needs. DSC tokens offer strong security and wide acceptance. E-stamps are suitable for automated processes. Aadhaar-based signing is convenient for Aadhaar holders.
