What is Identity Verification?

Identity verification is collecting, validating, and confirming personal data and documentation an individual provides to establish their identity. This process involves verifying information such as names, addresses, dates of birth, and government ID numbers to ensure that individuals do not submit false information on applications or when opening accounts.

The specific method and identity verification process may vary depending on your business model. However, all forms of identity verification strive to compare the information the user provides with verified datasets to verify the authenticity of their profile.

For instance, users may be asked to provide their name, address, date of birth, Social Security number, etc.

An effective identity verification process involves comparing this information against datasets such as government-issued IDs or third-party databases to confirm the person's identity.

Identity verification works by using signals to compare these data. They include 

How Does Identity Verification Work?

At its core, identity verification is the process of ensuring that an individual is who they claim to be. This process typically involves checking identity information against trusted sources and using various methods to confirm the authenticity of the person. Here’s a breakdown of the primary components:

a. Data Collection

• Personal Information: This includes the collection of basic personal information such as name, date of birth, and address. Often, this information is provided by the user during registration or application processes.
• Documents: Documents such as passports, driver’s licenses, and national ID cards are commonly used for verification. These documents contain essential data and security features that can be checked against databases and standards.

b. Document Verification

• Optical Character Recognition (OCR): Advanced OCR technology scans and extracts text from identity documents. This extracted information is then compared with the data provided by the user.
• Security Features: Documents have various security features like holograms, watermarks, and barcodes. Verification systems check these features to ensure the document is genuine.

c. Biometric Verification

• Facial Recognition: This method involves comparing the user’s live photo or video with the photo on their ID document. Facial recognition technology ensures that the person presenting the ID is its rightful owner.
• Fingerprint Scanning: Fingerprints are unique to each individual. This method captures and compares fingerprints against existing records.
• Voice Recognition: Voice recognition systems analyze the user’s voice patterns and match them against pre-recorded samples.

d. Database Checks

• Government Databases: Verification systems cross-check the provided information and documents against government databases. This step is crucial for confirming the authenticity of IDs and detecting any fraudulent activity.
• Watchlists: For added security, identity verification processes often include checks against global watchlists, such as those maintained for anti-money laundering (AML) and counter-terrorism purposes.

e. Behavioural Analysis

• User Behavior: Behavioral biometrics analyze how a user interacts with a system, such as typing speed, mouse movements, and touchscreen behaviour. These patterns help in identifying and verifying the user.
• Transaction Monitoring: Monitoring user transactions over time can reveal patterns that indicate whether the user is who they claim to be.

The Importance of Identity Verification

Identity verification is vital for various reasons:

• Security: It protects against identity theft and fraud, ensuring that only authorised individuals can access certain services and information.
• Regulatory Compliance: Many industries, especially finance and healthcare, have strict regulations regarding identity verification. Compliance with these regulations is essential to avoid legal repercussions.
• Trust and Credibility: For businesses, verifying the identity of customers fosters trust and credibility. Customers are more likely to engage with services that prioritise security.
• Efficiency: Automated identity verification processes speed up onboarding and reduce the need for manual checks, improving the overall user experience.

7 Pillars of Effective Identity Verification

Adequate identity verification is crucial for security and trust in various industries, from financial services to online platforms. Here are the core principles that constitute an effective identity verification solution:

1. Accuracy

Verification processes should be accurate and reliable. This includes using multiple data sources and validation methods to ensure the claimed identity is legitimate.

2. Multi-factor authentication (MFA)

To enhance security, it's advisable to use a multi-factor verification approach that combines something the user knows (such as a password or PIN),' something the user possesses (like a smartphone or security token), and something the user inherently is' (for instance, biometric identifiers like fingerprints or facial recognition). This approach increases the difficulty for unauthorised individuals to gain access.

3. Data privacy and security:

Protect the personal information used for verification. In creating an identity verification system, you must implement robust data security measures, such as encryption and secure storage, to prevent data breaches.

4. Risk-based assessment:

Risk-based assessment involves evaluating the level of risk associated with a user or transaction and then applying the appropriate verification scrutiny based on that assessment.

The critical aspect of risk-based assessment is its dynamic nature. Instead of using a one-size-fits-all solution, it customises the verification process according to the identified level of risk. This means simple verification methods suffice for low-risk scenarios, while high-risk situations require more stringent measures such as multi-factor authentication or manual review processes.

5. User experience

User experience (UX) in identity verification involves designing a smooth and user-friendly process while maintaining necessary security standards. UX is a core principle because it directly impacts how users perceive and engage with the verification process and the service or platform implementation.

A well-designed UX for identity verification ensures that complex or time-consuming procedures do not deter legitimate users. It minimises friction by reducing the steps required for verification or ensuring that instructions are clear and easy to follow. This is crucial because a negative experience can result in abandoned transactions, decreased customer satisfaction, and potential harm to the business's reputation.

 6. Regulatory compliance

No matter the identity verification procedure you put in place for your users, it has to adhere to relevant data protection and privacy regulations, such as GDPR or HIPAA, and industry-specific requirements like KYC (Know Your Customer) and AML regulations.

7. Scalability:

Build security systems that can scale to accommodate growing user bases without compromising security or efficiency.

Future Trends in Identity Verification

The field of identity verification is continually evolving, driven by advancements in technology. Some emerging trends include:

• Artificial Intelligence (AI): AI enhances the accuracy and efficiency of identity verification processes. Machine learning algorithms can detect fraudulent patterns and adapt to new threats.
• Blockchain Technology: Blockchain offers secure and transparent ways to manage and verify identities, reducing the risk of data breaches and tampering.
• Multi-Factor Authentication (MFA): Combining multiple verification methods, such as biometrics and passwords, provides a higher level of security.
• Decentralised Identity: This concept allows individuals to control their own identity data, granting access to specific parties as needed, rather than relying on centralised databases. 

9 Steps to Establishing an Effective Identity Verification System

Identity verification typically involves confirming that the person claiming to be a particular user is indeed that person.

Every business has a customised workflow to verify a user’s identity, but here’s a general procedure that can help you achieve your KYC obligations:

Step 1: Define your verification requirements:

Clearly define the level of identity verification needed based on the nature of your platform or service. Consider the sensitivity of the information involved and the regulatory requirements in your industry.

What Should Trigger an Alert During Identity Verification?

The primary purpose of conducting identity verification is to comply with AML regulations.

So you should have these factors in mind and incorporate them into your verification process to help fish out risks sooner:

a. Politically Exposed Persons (PEPs):

PEPs are individuals who are or have been entrusted with prominent public functions. This includes government officials, high-ranking military officers, senior executives of state-owned enterprises, and high-level officials in political parties.

Risk: 

• PEPs pose a higher risk of corruption and involvement in money laundering due to their positions of influence and access to public resources.

Red flags:

• Sudden wealth or financial transactions inconsistent with their known income
• Unexplained or immense transactions
• Complex ownership structures or transactions involving family members.

b. Adverse media

Adverse media refers to unfavourable information about an individual or entity publicly available through media sources. This can include news articles, legal records, and other sources of information.

Risk: Adverse media can indicate involvement in criminal activities, financial irregularities, or connections to sanctioned entities. 

Red Flags:

• Presence in news articles about unlawful activities, fraud, or corruption.
• Legal issues, such as involvement in lawsuits or regulatory actions.
• Association with individuals or entities under sanctions.

c. Unusual behaviour:

Are there rapid or frequent changes in account information? Has the user had multiple failed login attempts or password reset requests? 

These unusual behaviours should raise red flags. Also, unexpected changes in user behaviour, such as sudden large transactions or access from unique locations, are among the indicators for closer scrutiny.
