Properties of Digital Signature With SignNow
Award-winning eSignature solution
What digital signature properties mean
Properties of digital signature are the security and legal traits that make an electronic signature trustworthy, traceable, and hard to alter. In practice, a digital signature uses cryptography to bind a signer’s identity to a document, then records the signing event with timestamps, authentication data, and a tamper-evident seal. That combination helps confirm who signed, when they signed, and whether the file changed after signing.
Why digital signature properties matter
They reduce paper handling, speed approvals, and support enforceability under ESIGN and UETA when the signer’s intent, identity, and record integrity are preserved.
Frequent implementation pain points
Weak signer verification can leave attribution open to dispute, especially when the workflow relies only on email access. Missing audit details make it harder to show who signed, when they signed, and what changed afterward. Poor document retention can break internal policies or industry recordkeeping rules for healthcare, finance, or education. Confusing signature types can create gaps between a simple electronic signature and a higher-assurance digital signature.
Who uses digital signature properties
Real estate
Real estate teams use digital signature properties for leases, disclosures, and closing packets that need fast turnaround.
Healthcare
Healthcare organizations use them for consent forms, intake packets, and HIPAA-covered records with audit trails.
People who benefit most
A NetSuite operations lead at Xerox uses signNow to route the right documents to the right approvers, then keep the signing process aligned with ERP-driven workflows and document formats. The value is less manual rework, clearer routing, and easier coordination across business systems and teams. A founder at Martin Properties uses signNow to execute lease and property documents online with built-in security and mobile access. That matters when deals move quickly, parties are remote, and records still need a clear signing history for later review or dispute handling.

Core features and benefits
Digital signature properties combine identity, integrity, and traceability, which helps organizations sign and store records with more confidence.
Cryptographic binding
Creates a cryptographic link between the signer and the document, helping preserve integrity after signing and making later changes easier to detect.
Audit trail
Captures a clear signing history with timestamps, identity details, and event records that support review, audit, and dispute handling.
Mobile access
Supports mobile signing so documents can be completed on desktop, iPhone, iPad, or Android without changing the core record.
Workflow routing
Helps teams route documents in order, collect approvals faster, and reduce delays caused by paper handling or manual follow-up.
Reusable templates
Works with templates and reusable forms, which helps standardize recurring agreements and reduce setup time for repeated transactions.
Tamper evidence
Preserves document integrity with tamper-evident sealing, so post-signing edits are easier to identify during verification.
How the signing flow works
The signing process follows a simple sequence from document delivery to sealed record storage.
Open document: The signer opens the document and reviews the signing request. Verify signer: Identity checks confirm the signer before the signature is applied. Apply signature: The signature is attached and the document is sealed. Store record: The completed file and audit record are stored for review.
Quick setup steps
Use a short setup path to prepare, send, and store signed documents with less manual coordination.
Prepare file:
Upload the document and choose the signing order. Set recipients:
Add recipients and assign the required fields. Send request:
Send the request and monitor completion status. Save record:
Download the signed copy and archive it.
Recommended workflow settings
Set identity, integrity, and retention controls before sending regulated or business-critical documents.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP with ID verification |
| Signature type | Digital signature with PKI |
| Audit trail | Time-stamped, tamper-evident log |
| Document retention | 6 years (HIPAA 45 CFR 164.530(j)(2)) |
| Encryption | TLS 1.2/1.3 and AES-256 |
Platform and device support
Digital signature workflows run in modern browsers and on mobile devices, with secure connections required for signing and review.
Desktop browsers Chrome, Firefox, Edge, and Safari Operating systems Windows, macOS, iOS, and Android Mobile access Mobile apps for iOS and Android
For enterprise use, managed devices, SSO, API access, and retention controls matter more than the device itself. Windows and macOS desktops, plus iOS and Android phones or tablets, cover most signing scenarios.

Real-world use cases
Customer examples show how digital signature properties support routing, security, and faster completion in everyday business workflows.
Enterprise operations
A NetSuite operations team needed document routing that matched internal approvals and external customer workflows.
- Kodi-Marie Evans at Xerox used signNow with NetSuite.
- The team needed the right signatures on the right documents.
The workflow supported better document routing, fewer format mismatches, and faster coordination across systems. That kind of setup is useful when approvals depend on both process control and record accuracy.
Real estate
A property business needed online execution for agreements that still required security, mobile access, and reliable records.
- Tim Martin at Martin Properties signed documents online.
- Mobile and offline access helped keep work moving.
The result was faster execution and clearer recordkeeping for property documents. For real estate teams, that combination matters because it reduces paper delays while keeping the signing history available for later review.

FAQ and troubleshooting
These answers focus on plan limits, compliance needs, and record integrity issues that affect digital signature workflows.
signNow Business includes legally binding eSignatures, audit trails, templates, and mobile apps. If you need HIPAA support, confirm a BAA and keep the workflow aligned with the HIPAA Security Rule.
signNow supports HIPAA workflows when a BAA is in place. Use unique user identification, access controls, and audit controls to align with 45 CFR 164.312 and retain signed PHI records for six years.
For higher-assurance signing, use advanced signer authentication rather than email access alone. signNow’s Enterprise and Site License options add stronger controls, while ESIGN and UETA still require clear signer intent and attribution.
If a signed PDF looks altered, check the audit trail and document history first. signNow records signing events and tamper-evident history, which helps show whether changes happened before or after signature completion.
Bulk send is included in Business Premium. If you do not see it, your plan may be Business or lower. Upgrade only if your workflow needs high-volume, repeated sending.
For FDA-regulated records, 21 CFR Part 11 requires validation, secure audit trails, and unique electronic signatures. signNow can support controlled workflows, but your process still needs documented validation and access governance.
