In today’s digital world, more and more businesses, governments, and individuals are moving online. This shift makes security and authenticity of documents extremely important. Digital signatures provide a safe way to sign and verify documents electronically.
What is a Digital Signature?
A digital signature is an electronic method to confirm that a document is authentic and has not been altered. Using cryptography, it ensures the signer’s identity and protects the integrity of the document.
How It Works
Digital signatures use Public Key Infrastructure (PKI) with two keys:
- Private Key: Used by the signer to create the signature.
- Public Key: Used by others to verify the signature.
A unique hash of the document is created and encrypted with the private key. The recipient decrypts it with the public key to confirm authenticity.
Benefits
- Security: Prevents tampering.
- Authentication: Confirms signer’s identity.
- Integrity: Any changes invalidate the signature.
- Non-repudiation: Signer cannot deny signing.
- Efficiency: Saves time and paperwork.
- Legal Validity: Recognized by laws like eIDAS (EU) and ESIGN (USA).
Uses
- Banking & Finance: Loans, transfers, account management.
- Government: Tax filings, certificates.
- Healthcare: Records, prescriptions.
- Legal: Contracts, agreements.
- Education: Forms, certificates.
