How to Verify Digital Identity

Verification Methods

There are several methods used in digital verification, but the common ones include: 

• Document Verification: This method involves verifying identity by checking government-issued documents like passports, driver’s licenses, or national ID cards. With this method, documents can be scanned or uploaded digitally for verification. Online platforms use advanced AI systems to detect forgeries, tampering, or expired documents.

• Database Checks: This method validates user information by cross-referencing official databases. A common example of a database check is verifying ID numbers or names against government or public records. Database checks are widely used by financial institutions and government agencies to quickly confirm identity.

• Proof of Address Checks: This method involves verifying an individual’s address by checking documents like utility bills (e.g., electricity, water, or gas bills), bank statements, and rental or lease agreements. Users can submit these documents, which usually contain their address details, by scanning them with their mobile phone cameras.

3 Steps for Verifying Digital Identity

Step #1: Collect User Data Securely

Begin by securely gathering personal information and necessary documents from the user. Data collected at this stage can include names, dates of birth, and ID document information. Ensure to use encrypted platforms or secure web portals when collecting data to prevent data breaches.

Step #2: Cross-check Details Against Trusted Sources

After collecting the data, it is validated against reliable sources to ensure authenticity. For example, an uploaded ID can be checked against government records. In some cases, biometric data like a selfie can be matched with a photo on the uploaded ID document. This step eliminates any discrepancies or fraudulent submissions.

Step #3: Ensure Real-time Processing to Minimize Delays

Modern digital identity verification systems are designed for fast, automated checks. Real-time processing ensures users don’t have to wait long for approval. This has been made possible with AI tools that can instantly scan and verify IDs or perform facial recognition within seconds.

Common Uses for Digital Identity

• Opening Accounts: Digital identity simplifies the onboarding process for new users by automating the verification of credentials. For example, when opening a bank account, users can submit ID documents, biometrics, or personal information through the bank’s online portal without needing to visit a physical location.

• Account Recovery: If users lose access to their accounts due to forgotten credentials, digital identity helps them regain access easily and securely. Verification methods like biometric authentication ensure that only authorized users can recover accounts.

• High-Risk Transactions: Digital identity adds an extra layer of security for sensitive transactions to protect against fraud. Common examples of such transactions include transferring large sums of money, purchasing expensive items online, or approving corporate-level actions. To ensure security, multi-factor authentication (MFA), biometric checks, or real-time verification are commonly used in these scenarios.

Digital Identity for Financial Services

Role in Banking and Finance

Digital identity verification in the banking sector is implemented in the following ways:
