Electronic Signature vs Digital Signature: What's the Difference?
In today's paperless workplace, getting contracts signed online is standard. However, people regularly use the terms Electronic Signature (eSign) and Digital Signature interchangeably.
Legally and technically, they are not the same. Using the wrong type of signature can make your business contracts invalid in court or expose you to document forgery. Let's explain the differences in plain, simple English.
1. What is an Electronic Signature (e-Sign)?
An Electronic Signature is a broad legal category. It represents any electronic mark, sound, or symbol associated with a contract, indicating a person's intent to sign.
Common Examples:
- Drawing your signature on a touchscreen canvas.
- Typing your name using a cursive calligraphy font.
- Uploading an image of your physical pen signature.
- Clicking an "I Accept" checkbox on a website form.
Legal Status:
Under the US ESIGN Act (2000) and India's IT Act (2000), electronic signatures are legally binding for most standard agreements (like sales NDAs, HR forms, and invoices).
2. What is a Digital Signature? (Cryptographic Lock)
A Digital Signature is a highly secure subcategory of electronic signatures. It does not just show intent; it uses advanced mathematics to cryptographically bind your identity to the document.
How it Works:
- PKI (Public Key Infrastructure): Uses a private key (held by the signer) and a public key.
- DSC (Digital Signature Certificate): Issued by government-licensed Certifying Authorities (like eMudhra in India) after verifying your identity (PAN/Aadhaar e-KYC).
- Tamper-Evident Lock: If anyone tries to modify even a single character in the PDF after it is signed, the digital signature breaks, notifying all parties of tampering.
