How to ensure the security level of signer identity verification?

Ensuring Security in Signer Identity Verification

In the digital age, electronic signatures have revolutionized business transactions, offering speed and convenience. However, as reliance on eSignature platforms grows, so does the need to protect against identity fraud. From financial agreements to legal contracts, verifying the signer’s identity is crucial to prevent unauthorized access and ensure compliance with regulations like eIDAS in Europe or ESIGN Act in the US. Businesses must adopt robust strategies to maintain trust and mitigate risks in this evolving landscape.

Key Strategies for Robust Signer Identity Verification

Understanding the Importance and Risks Involved

Signer identity verification is the backbone of secure eSignature processes. Without it, documents could be signed by imposters, leading to financial losses, legal disputes, and reputational damage. Common risks include phishing attacks, where fraudsters intercept signing links, or deepfake manipulations that bypass basic checks. In high-stakes industries like banking, healthcare, and real estate, a single breach can result in millions in damages. According to industry reports, identity fraud in digital transactions rose by 20% in 2024, underscoring the urgency for advanced verification.

From a commercial perspective, companies investing in strong verification not only comply with standards but also build customer confidence. This translates to higher adoption rates and reduced churn. The goal is to balance security with user experience—overly stringent checks can frustrate signers, while lax ones invite vulnerabilities.

Implementing Multi-Factor Authentication (MFA)

One foundational method is multi-factor authentication, which requires signers to prove their identity through multiple independent credentials. Start with something they know (e.g., password or PIN), combined with something they have (e.g., a one-time code via SMS or authenticator app), and ideally something they are (biometric data like fingerprint or facial recognition).

For businesses, integrating MFA into eSignature workflows is straightforward via APIs from providers. For instance, SMS delivery for codes ensures accessibility, but pair it with app-based authenticators to counter SIM-swapping attacks. Testing shows MFA reduces unauthorized access by up to 99%. Ensure your platform supports adaptive MFA, which escalates checks based on risk factors like unusual IP locations.

Leveraging Document and Biometric Verification

Beyond basic MFA, document verification adds a layer by requiring signers to upload government-issued IDs, such as passports or driver’s licenses. Use optical character recognition (OCR) to extract and validate details against databases, flagging inconsistencies like mismatched names or expiration dates.

Biometric checks take this further with liveness detection—ensuring the signer is a real person, not a photo or video replay. Technologies like 3D facial mapping or voice analysis detect spoofs with over 95% accuracy. In practice, prompt signers during the process: “Please take a live selfie while holding your ID.” This method is particularly effective for remote signing in global operations, where physical notaries aren’t feasible.

Commercial tip: Opt for metered pricing on these features to control costs, as high-volume users might face add-on fees. Always audit logs to track verification attempts, aiding in forensic analysis if disputes arise.

Incorporating Knowledge-Based and Behavioral Analysis

Knowledge-based authentication (KBA) quizzes signers with personal questions derived from credit reports or public data, such as “What was your first car?” High-security variants use out-of-wallet questions to evade social engineering.

Behavioral biometrics analyze signing patterns—keystroke dynamics, mouse movements, or device fingerprints—to create a unique profile. Anomalies, like signing from a new device, trigger additional challenges. This passive approach enhances security without interrupting the flow.

To implement effectively, businesses should conduct regular risk assessments. For example, in APAC regions with varying data privacy laws, ensure verification aligns with local standards like PDPA in Singapore. Training teams on these tools is essential; a 2025 survey found that 70% of breaches stem from misconfigurations.

Best Practices for Ongoing Security and Compliance

Regularly update verification protocols to counter emerging threats, such as AI-generated deepfakes. Partner with certified providers offering end-to-end encryption for data in transit and at rest. Conduct penetration testing and third-party audits to validate systems.

Compliance is non-negotiable: Map features to regulations, retaining verifiable audit trails for seven years in many jurisdictions. For global businesses, multi-regional support prevents silos. Finally, educate signers on phishing risks via in-app tips, fostering a security-aware culture.

By prioritizing these methods, companies can achieve a high security level, reducing fraud by 80-90% while streamlining operations. This proactive stance not only safeguards assets but positions firms as reliable partners in the digital economy.

Challenges Faced by Leading eSignature Providers

Adobe Sign’s Pricing Opacity and Market Exit from Mainland China

Adobe Sign, once a strong contender in the eSignature space, has faced criticism for its opaque pricing structure. Businesses often struggle with hidden fees for add-ons like identity verification, leading to unpredictable costs that escalate with usage. This lack of transparency can deter small to medium enterprises seeking budget predictability.

More notably, Adobe Sign announced its withdrawal from the mainland China market in 2023, citing regulatory complexities and data localization challenges. This move left many APAC-based users scrambling for alternatives, disrupting ongoing workflows and forcing migrations. The exit highlighted vulnerabilities in global platforms reliant on uniform operations, particularly in regions with stringent data sovereignty rules.

DocuSign’s Elevated Costs, Lack of Transparency, and APAC Service Gaps

DocuSign dominates the eSignature market but draws flak for its high pricing and billing practices. Core plans like Business Pro start at $40 per user per month (annual), but envelope limits—around 100 per user per year—quickly lead to overages. Add-ons for identity verification, such as biometric checks, are metered and can inflate bills significantly, with little upfront clarity on total ownership costs. API integrations, vital for automation, range from $600 to over $5,000 annually, making scalability expensive for growing firms.

In long-tail regions like APAC, service inconsistencies compound issues. Cross-border latency slows document loading, and limited local ID verification options fail to meet regional compliance needs, such as China’s CAC regulations. Support costs are higher, and data residency surcharges add friction, prompting many to question DocuSign’s value in non-US markets.

eSignGlobal: A Regionally Optimized Alternative

eSignGlobal emerges as a compelling option, particularly for APAC-focused businesses. It offers transparent pricing with flexible plans tailored to regional needs, avoiding the envelope caps that plague competitors. Identity verification features, including local ID methods and biometric support, are natively compliant with CN, HK, and SEA regulations, ensuring faster processing without latency issues.

While not without its learning curve for global teams, eSignGlobal’s emphasis on data residency and cost efficiency makes it appealing for cross-border operations. Its API is more accessible for mid-sized integrations, promoting scalability without prohibitive fees.
