Ensuring the security and integrity of user identity has become a priority for businesses and individuals. Online identity verification has emerged as a reliable solution, helping organisations establish the identity of users and detect potential fraud or malicious activity. It’s estimated that 1 in 15 people globally is affected by a form of identity fraud, making protection for your business more important than ever.

In this guide, we will delve into the concept of online identity verification, its importance, risks and challenges, the process of online ID checking, and the benefits it offers. We will also discuss the technologies currently used and explore the benefits of using mobile data to enhance identity verification.

Definition of identity verification

Identity verification is the process of confirming the authenticity and legitimacy of an individual’s claimed identity. It involves establishing the accuracy and validity of various identity attributes, such as name, age, address, and any other relevant information.

How is identity verification different from authentication?

Identity verification is the process of confirming the identity of an individual by establishing the accuracy and validity of various identity attributes, such as name, age, address, and other relevant information. It aims to ensure that the person claiming an identity is indeed who they say they are. Identity verification typically involves verifying identification documents and conducting background checks. Mobile data can be used to speed up this process.

Authentication, on the other hand, is the process of verifying the identity of a user during a specific session or interaction. It ensures that the user attempting to access a system or perform a transaction is the same individual who was verified during the identity verification process. Authentication is typically done through credentials such as usernames, passwords, one-time verification codes, biometrics, device information, Mobile Network Operator (MNO) data or other forms of secure tokens.

Importance of digital ID verification

Digital ID verification plays a vital role in ensuring the trustworthiness and security of online transactions and account access. By verifying the identities of users, businesses can prevent identity theft, comply with regulatory requirements, reduce fraud, enhance cybersecurity measures, and establish a seamless and trustworthy user experience.

Evolution of online identity verification

Over the years, online identity verification methods have evolved to keep up with the changing landscape of fraud threats. Advancements in technology have paved the way for more sophisticated and robust verification methods, such as biometrics and facial recognition. These technologies have often replaced traditional methods, such as physical document verification, to provide a faster and more reliable means of verifying identity, improving both accuracy and user experience.

Common methods of ID verification

  • Document verification: this method involves verifying the authenticity of identification documents such as passports, driving licences, and identity cards. Digital solutions now enable businesses to verify documents remotely using advanced algorithms.
  • SMS verification: SMS verification such as one-time passcodes involves sending a code to a registered mobile number, which the user must enter to validate their identity. This method confirms the possession of the mobile device associated with the registered number. However, there are risks associated with this method due to account takeover frauds such as SIM swapping.
  • Device verification: device verification analyses the device used by an individual to determine its trustworthiness. This method considers factors such as device type, location, IP address, and other device-related attributes.
  • Authentication apps: authentication apps generate time-sensitive codes that users need to input for verification. These apps can be installed on smartphones and provide an additional layer of security.
  • Biometric verification: biometric verification uses unique biological or behavioural attributes, such as fingerprints, facial features, or voice recognition, to verify identity.
  • Credit check-based verification: this method involves checking an individual’s credit report and credit score to verify their identity. It assesses patterns and discrepancies in financial behaviour.
  • Two-factor authentication: two-factor authentication requires users to provide two separate forms of identification, such as a password and a one-time verification code sent via email or SMS.

Risks and challenges in identity verification

While identity verification methods provide enhanced security, they are not immune to risks and challenges:

  • Identity theft: identity theft involves unauthorised access to an individual’s personal information for fraudulent purposes. It can result in significant financial and reputational damage.
  • Phishing: phishing involves fraudulent attempts to obtain sensitive information, often through deceptive emails or websites designed to mimic legitimate entities.
  • SIM swap and account takeover: SIM swap attacks occur when a malicious actor convinces a phone carrier to transfer a victim’s mobile number to a device they control, allowing them to intercept verification messages and gain access to accounts.
  • Data breaches: data breaches occur when unauthorised individuals gain access to sensitive data stored by organisations. Stolen data can be used for identity theft, causing financial loss, damaged credit, reputational damage and emotional distress for the victim.

Consequences of poor or lengthy identity verification processes

There are significant consequences for businesses that don’t get the balance right when it comes to their online identity verification process. Regulated industries have a legal obligation to carry out ID checks — in 2022, over £1.2 billion was stolen through online fraud from UK banking customers alone.

However, it is still important to make these checks as streamlined as possible to avoid creating a poor user experience. If your verification process is too cumbersome it can directly impact customer acquisition and retention rates. On the other hand, if ID checks are not sufficient, businesses are at a much greater risk of becoming a victim of online fraud or finding themselves in legal trouble with the associated regulators. Mobile data is a reliable source of customer data, which can be fully integrated into your existing processes with no extra friction.

What is digital ID checking?

Online or digital ID checking is the process of verifying an individual’s identity through digital means. Rather than relying on in-person verification, online ID checking leverages technology and various verification methods to establish trust and verify identity remotely.

How digital ID verification works

Digital ID verification involves the use of automated processes, algorithms, and technological solutions to verify identity attributes. It combines different verification methods, including document verification, biometrics, device checks, and more, to establish a comprehensive identity profile and determine the authenticity of the claimed identity.

Data provided by Mobile Network Operators is also a powerful tool for digital ID verification. It is a form of trusted data, rarely changed by customers compared to traditional factors such as address, and it is much harder to fake or manipulate for the purposes of fraud.

Traditional ID checks vs online verification API

Traditional ID checks, such as physical document verification, are time-consuming and often subject to human error. Online verification APIs allow businesses to automate the verification process, ensuring greater accuracy, efficiency, and scalability. They integrate with various verification methods, enabling a seamless and real-time identity verification experience.

The benefits of digital ID verification

  • Regulatory compliance: digital ID verification helps organisations meet regulatory requirements related to customer identification, Anti-Money Laundering (AML), Know Your Customer (KYC) rules, and more.
  • Enhanced fraud prevention and cybersecurity: by employing multiple verification methods and real-time checks, digital ID verification significantly reduces the risk of fraud and strengthens overall cybersecurity measures.
  • Cost efficiency: automated digital ID verification processes streamline operations, reduce manual effort, and minimise the costs associated with traditional identity verification methods.
  • Improved customer experience: digital ID verification provides a seamless and user-friendly experience, eliminating the need for individuals to physically present documents or visit offices for identity verification.

Best practices for implementing online identity verification

When considering the best approach for your online identity verification processes, there are a few implications to consider — striking the right balance between robust checks and additional friction. It’s important to choose the right verification method for your customers; using mobile data is a great way of doing this since most customers will own a mobile device. You must also ensure compliance with the legal requirements for ID checks in your jurisdiction and industry. Keep your processes as streamlined as possible to protect customer retention, and review them regularly — the sophistication of cyberattacks is always improving, so updating your processes to protect against the latest risks is essential.

How mobile data strengthens identity verification

Mobile data provides valuable insights and strengthens identity verification in several ways. Mobile data verification techniques, such as device intelligence checks, provide real-time and contextual information, making them more reliable and accurate than traditional methods. Mobile data sources offer comprehensive and up-to-date information, enabling businesses to verify identity attributes with a higher level of confidence. Mobile data is available globally and is much more standardised than other forms of ID verification data. And mobile number databases can be accessed in less than a second using a mobile data API, both speeding up the process and reducing costs compared to checking physical ID documents.

Industries embracing digital identification

  • Financial services: Know Your Customer (KYC) and Anti-Money Laundering (AML) checks require banks and other financial institutions to carry out online ID checks to protect against fraud.
  • Healthcare: as more patients access healthcare remotely and online, digital identity verification is becoming more important to ensure consistent patient information and protect it from falling into the wrong hands.
  • E-commerce: as fraudulent transactions continue to rise online, it has become increasingly important for eCommerce businesses to carry out ID checks to protect from the costs of cybercrime.
  • Travel and hospitality: online ID checks are increasingly used to confirm that the person renting a holiday property is who they say they are, helping protect the property owner from damage and other risks.
  • Gambling and gaming: gambling companies have a legal obligation to ensure platform users are over 18. Mobile ID verification allows them to reduce friction in their onboarding process.
  • Adult entertainment: increasing legislation requires the adult industry to carry out full ID verification for users. A mobile phone number is often used to do this instead of credit card details.

Online verification APIs for frictionless ID checks

For all these industries and more, online verification API tools are almost always the quickest and most effective way to streamline existing ID checks. They can be integrated into existing systems and the associated mobile data lookups can be returned quickly from anywhere in the world. They are also more reliable when leveraging mobile network operator data, as it is harder to manipulate.

Final thoughts

Online identity verification is a critical aspect of conducting secure and trustworthy online transactions. By leveraging technologies like mobile data APIs and biometric verification, businesses can establish a robust and efficient online identity verification process that balances security and user experience effectively.
