Digital Signature vs Electronic Signature: What Florida Notary Clients Need to Know
When you notarize a document online in Florida, you sign electronically. But not all electronic signatures are the same. The terms "electronic signature" and "digital signature" are often used interchangeably, yet they describe fundamentally different technologies with different legal implications.
Understanding the difference helps you know what you are getting when you use Remote Online Notarization and why Florida law requires specific signature standards.
What Is an Electronic Signature?
An electronic signature is any electronic sound, symbol, or process attached to a document with the intent to sign it. Under the federal ESIGN Act and Florida's Uniform Electronic Transactions Act (UETA), electronic signatures are legally valid for most documents.
Common forms of electronic signatures include:
- Typing your name into a signature field
- Drawing your signature with a mouse or finger
- Clicking an "I agree" button
- Using a stylus on a touchscreen
- Pasting a scanned image of your handwritten signature
Electronic signatures are convenient and widely accepted. However, they do not inherently prove who created the signature or prevent tampering after signing.
What Is a Digital Signature?
A digital signature is a specific type of electronic signature that uses cryptographic technology to provide:
- Authentication — Confirms the identity of the signer
- Integrity — Detects any changes to the document after signing
- Non-repudiation — Prevents the signer from denying they signed
Digital signatures rely on public key infrastructure (PKI). The signer has a private key that encrypts a unique hash of the document. The recipient uses the signer's public key to verify the signature. If the document is altered after signing, the verification fails.
How Digital Signatures Work in Online Notarization
Florida's Remote Online Notarization law requires notaries to use electronic seals that include digital signature technology. Here is how it works in practice:
The Signer's Electronic Signature
When you sign during an online notarization session, you create an electronic signature by drawing or typing your signature. This signature is legally valid under ESIGN and UETA.
The Notary's Digital Seal
The notary applies an electronic seal that includes a digital certificate issued by a trusted certificate authority. This digital seal:
- Is cryptographically linked to the notary's commission
- Contains a timestamp of the notarization
- Creates a tamper-evident seal on the document
- Can be verified by anyone who receives the document
If someone alters the document after notarization, the digital seal shows that the document has been tampered with.
Legal Validity in Florida
Florida recognizes both electronic signatures and digital signatures under specific statutes:
Uniform Electronic Transactions Act (UETA)
Florida adopted UETA in 2000. It provides that electronic signatures are legally equivalent to handwritten signatures for transactions governed by Florida law. UETA does not require digital signatures — any electronic signature that shows intent to sign is sufficient.
ESIGN Act (Federal)
The federal Electronic Signatures in Global and National Commerce Act applies to interstate commerce. Like UETA, ESIGN validates electronic signatures without requiring digital signature technology.
Florida Remote Online Notarization Statute
Florida Statute 117.285 specifically governs online notarization. It requires:
- Electronic signatures for the signer and notary
- Electronic seals that meet Florida Department of State standards
- Tamper-evident technology that shows if the document is altered
While the statute does not explicitly mandate PKI-based digital signatures for signers, it requires tamper-evident technology for the notary's seal, which is typically implemented through digital signatures.
When Digital Signatures Matter Most
For everyday documents, a basic electronic signature is legally sufficient. Digital signatures become critical in high-stakes situations:
Real Estate Transactions
Deeds, mortgages, and closing documents involve substantial financial risk. Digital signatures protect all parties by preventing post-signing alterations and proving the exact time of execution.
Legal and Court Documents
Documents submitted to courts or used as evidence benefit from the authentication and integrity guarantees of digital signatures.
Government Filings
Federal and state agencies increasingly require digital signatures for regulatory submissions, tax documents, and official records.
Financial and Healthcare Records
Banks, insurance companies, and healthcare providers use digital signatures to comply with data security regulations and prevent fraud.
Common Misconceptions
"Electronic signatures are not legally binding."
False. Electronic signatures have been legally valid in Florida since 2000 and federally since 2000. Millions of contracts are executed electronically every day.
"Digital signatures and electronic signatures are the same thing."
False. All digital signatures are electronic signatures, but not all electronic signatures are digital signatures. Digital signatures add cryptographic security.
"I need special software to create a digital signature."
Partially true. Creating a PKI-based digital signature requires software that manages cryptographic keys. However, most users interact with digital signatures through platforms like Rush Notary that handle the cryptography automatically.
"A scanned image of my signature is just as good."
Not quite. A scanned image is an electronic signature, but it lacks authentication and tamper-evidence. It is easy to copy and paste a scanned signature onto unauthorized documents.
How Rush Notary Handles Signatures
Rush Notary uses a layered approach:
For Signers:
- You create an electronic signature by drawing or typing during the video session
- The signature is captured in real time while the notary witnesses
- The signature is embedded into the document and cannot be copied to other documents
For Notaries:
- The notary applies an electronic seal with a digital certificate
- The seal is cryptographically bound to the document
- The seal includes a timestamp and the notary's commission information
- Any alteration to the document after sealing invalidates the seal
For Document Delivery:
- You receive a tamper-evident PDF
- The PDF shows if it has been modified since notarization
- The notary's digital certificate can be verified by any PDF reader that supports digital signatures
Verifying a Digital Signature on Your Notarized Document
You can verify the digital signature on your Rush Notary document using Adobe Acrobat Reader or similar PDF software:
- Open the notarized PDF
- Look for a signature panel or notification indicating a digital signature
- Click on the signature to view details
- Confirm the signature is valid and the document has not been altered
- Review the certificate chain to confirm it was issued by a trusted authority
If the signature shows as invalid or the document shows as modified, contact Rush Notary immediately.
Frequently Asked Questions
Q: Can I use a digital signature for personal documents?
Yes, though for most personal documents a basic electronic signature is sufficient. Digital signatures are most valuable for legal, financial, and business documents.
Q: Does Florida require digital signatures for contracts?
No. Florida recognizes all electronic signatures that demonstrate intent to sign. Digital signatures are optional unless specifically required by the receiving party.
Q: Are digital signatures hack-proof?
No security measure is entirely hack-proof, but digital signatures are extremely difficult to forge. Breaking a properly implemented digital signature requires computational resources that are not practically available.
Q: Can I create my own digital signature certificate?
Technically yes, but self-created certificates are not trusted by others. For legal and business use, you need a certificate issued by a recognized certificate authority.
