Can ID Verification Alone Prevent Identity Theft in Financial Services?

Can ID Verification Alone Prevent Identity Theft in Financial Services?

This is the third article in ARGOS’ Practical eKYC Guide for Financial Service Providers.

In the previous article, we covered five key capabilities financial service providers should consider when selecting an eKYC solution: ID document OCR, ID authenticity and fraud detection, Face Match, Liveness Detection, and global ID document coverage.

But how do these technologies help solve real-world challenges in digital financial services?

One of the most important use cases is preventing identity theft, impersonation, and fraudulent account activity.

For financial service providers, accurately extracting information from an ID document is only the beginning. They also need to determine whether the document itself is legitimate and whether the person attempting to use the service is actually the rightful owner of that identity.

Because users cannot be verified face-to-face in a remote environment, relying on a single verification method may leave gaps. Instead, financial service providers need an eKYC process that progressively connects the identity document to the actual person presenting it.

A Valid ID Does Not Necessarily Mean the User Is the Rightful Owner

When we think about identity verification, the first step that often comes to mind is verifying whether an ID document is legitimate.

Checking whether the submitted document was legitimately issued and whether its image or information has been manipulated is an essential part of the process.

But there is another important question:

What if someone submits a legitimate ID document that belongs to another person?

In this case, there may be nothing wrong with the document itself.

In other words, confirming that an ID is valid and confirming that the person using the service is the rightful owner of that ID are two different things.

For remote identity verification, financial service providers need to address both questions:

1. Can we trust this identity document?

2. Can we trust the person presenting it?

An eKYC process designed to prevent identity theft needs to answer both.

Step 1. Verify the Submitted Identity Document

The first step is to verify the ID document submitted by the user.

Rather than simply using OCR to extract information such as name, date of birth, and ID number, the verification process should also determine whether the submitted document can be trusted.

When considering risks such as image manipulation, altered personal information, or forged documents, ID authenticity checks and document fraud detection become particularly important.

A typical ID verification flow may look like this:

ID Capture → Data Extraction → Authenticity Check → Fraud Detection

The purpose of this process is not simply to collect identity information. It is to determine whether the submitted identity document itself can be trusted.

However, document verification alone cannot fully address identity theft.

The next step is connecting that document to the actual person attempting verification.

Step 2. Match the ID Owner with the Current User

Once the identity document has been verified, the next question is about the person presenting it.

Is the person currently completing verification the same person shown on the ID?

This is where Face Match comes into play.

Face Match compares the facial image on the identity document with a selfie captured during the verification process to determine whether they belong to the same person.

This is particularly important in financial services because a fraudster may attempt to use someone else’s legitimate identity document.

For example, if an individual obtains another person’s ID document or identity information and attempts to complete verification, checking only the validity of the document may not be enough to identify the impersonation attempt.

Step 3. Verify That a Real Person Is Present

Even after Face Match is introduced, one more question remains.

Was the facial image submitted during verification captured from a real person who is actually present at that moment?

Fraudsters may attempt to bypass facial verification using printed photos, images displayed on another screen, prerecorded videos, or other presentation attacks.

This is where Liveness Detection becomes important.

Liveness Detection helps determine whether a real person is physically participating in the verification process.

For remote identity verification, the following capabilities should therefore work together as part of a single verification flow:

ID Verification → Face Match → Liveness Detection

Each component answers a different question:

ID Verification: “What identity is this person claiming?”

Face Match: “Is the current user the rightful owner of this identity?”

Liveness Detection: “Is a real person actually present during verification?”

Connecting these capabilities creates a stronger foundation for verifying the actual person behind an online identity.

When Should These Verification Steps Be Applied?

This does not mean financial service providers should require users to submit an ID and complete facial verification every time they use a service.

Adding too many verification steps can create friction and potentially increase user drop-off.

Instead, financial service providers should first identify where identity-related risk increases throughout the customer journey and apply the appropriate level of verification at those points.

For example:

Initial KYC

When onboarding a new user, it is important to establish a trusted identity by connecting the submitted identity document with the actual person.

Increasing Account or Transaction Limits

When a user requests access to higher transaction limits or expanded financial services, providers may need to determine whether the identity information already collected is sufficient.

Withdrawals or High-Risk Transactions

For sensitive transactions involving the movement of funds, additional verification may be necessary to confirm that the person initiating the transaction is the same user who was previously verified.

Changes to Critical Account Information

Additional identity verification may also be appropriate when users change important information that could affect account access or financial transactions.

The goal is not to apply the same verification process everywhere.

It is to apply the appropriate level of identity verification when risk increases.

Preventing Identity Theft Is Not About Adding More Verification Steps

Adding more authentication and verification steps may improve security, but it can also make the user experience unnecessarily complex.

The key is not simply how many verification steps are used, but whether each step has a clearly defined role.

For example, during initial KYC, a financial service provider may establish the user’s identity using an ID document and facial verification.

Later, when the user needs to be verified again, requiring the same person to resubmit their identity document every time may not be necessary.

Instead, the provider can use previously verified identity information and introduce a simpler re-verification process.

The customer journey might therefore look like:

Initial Identity Verification → Service Usage → Risk Signal or Sensitive Transaction → Additional User Verification

This risk-based approach can reduce unnecessary friction for legitimate users while introducing stronger identity verification when it matters most.

Identity Theft Prevention Checklist for Financial Service Providers

Financial service providers can use the following questions to evaluate their current identity verification process.

ID Document Verification

• Does the process go beyond simply extracting information from an ID?

• Can it verify whether the submitted identity document is legitimate?

• Can it detect potential document manipulation or forgery?

User Verification

• Is the person shown on the ID compared with the actual user?

• Is Face Match included in the verification process?

• Can the system determine whether a real person is participating in facial verification?

Customer Journey

• Have you defined when users should be re-verified after initial onboarding?

• Can verification requirements be adjusted based on transaction or account risk?

• Are users unnecessarily required to resubmit their ID for every sensitive transaction?

Operations

• Can suspicious or abnormal verification attempts be identified?

• Can operations teams understand why a verification attempt failed?

• Is the verification process simple enough for legitimate users to complete without unnecessary friction?

Preventing identity theft requires more than a single verification technology.

Financial service providers need to consider how identity documents are connected to actual users and when those users should be verified again.

From ID Documents to Real Users: Build a Connected eKYC Flow

ARGOS ID Check connects ID document OCR, ID verification, Face Match, and Liveness Detection within a single eKYC process, helping financial service providers verify both the identity document and the actual person presenting it in a remote environment.

Once a user has completed initial KYC, there may also be situations where the service needs to confirm their identity again.

In these cases, ARGOS Face Auth can enable facial re-verification based on previously verified user information, without requiring users to repeatedly submit their identity documents.

For financial services, stronger identity security does not necessarily mean adding more verification steps.

Instead, it means connecting three fundamental questions:

Can we trust the identity document? → Is the current user its rightful owner? → Is a real person actually present?

By connecting these checks within a single verification flow and applying the appropriate level of verification when risk increases, financial service providers can build a more secure and user-friendly eKYC process.

If you are reviewing your current identity verification process to better prevent identity theft, impersonation, and fraudulent activity, explore how ARGOS can help you design an eKYC flow tailored to your service environment.

In the next article, we will look at another challenge for financial service providers: eKYC for foreign customers.

From passport and international ID document processing to fraud detection, Face Match, and Liveness Detection, we will explore what financial service providers need to consider when building an identity verification process for users across different countries.
