Although the technology and techniques used can be quite complex, the actual process that the consumer faces should seem simple. Here\u2019s what to know first.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>Customer verification defined<\/em>\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Customer identity verification is a security-minded procedure that enables businesses to prevent fraud, meet regulatory requirements, and secure user accounts and information. It is the process a business uses to confirm that interactions with the organization truly originate from the person or organization they claim to represent. Businesses today use advanced technology to verify customer identities, with as much certainty as possible.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The process can be as simple as confirming that a given user owns a particular account or as in-depth as using<strong> <\/strong>identity verification technology to check that a user\u2019s supplied credentials match some government databases. Verification is an essential process that must take place before any grant of authorization or access to systems, resources, accounts and other digital assets.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>Why customer verification matters<\/em>\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Why make the effort to verify customers consistently? One of the most important answers is also obvious: it\u2019s central to creating trust between organizations and customers. If you don\u2019t handle a user\u2019s information safely and verify that they\u2019re behind any action on the account, you could expose those users to risks, including identity theft and financial losses.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your organization can suffer similarly adverse effects from bad actors. A lack of or inferior customer verification opens the door to <a href=\"https:\/\/www.telesign.com\/blog\/account-takeover\" target=\"_blank\" rel=\"noreferrer noopener\">account takeovers<\/a>, fake account creation, spam and even fraud. Whether these issues consume resources or lead to <a href=\"https:\/\/www.telesign.com\/blog\/a-comprehensive-look-at-the-cost-of-fraud\" target=\"_blank\" rel=\"noreferrer noopener\">fraud-related losses<\/a>, neither outcome is conducive to doing business successfully.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Regulations in numerous industries, especially those connected to finance and banking, require organizations to use identity verification solutions. These rules include Know Your Customer (KYC) regulations and <a href=\"https:\/\/www.telesign.com\/blog\/aml-regulations-anti-money-laundering\" target=\"_blank\" rel=\"noreferrer noopener\">anti-money laundering (AML)<\/a> regulations. If you don\u2019t take steps to verify a customer&#8217;s identity, you could inadvertently facilitate criminal activities. Therefore, verification is unavoidable in building trust, guarding against fraud, and meeting legal requirements.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>Today\u2019s key methods for verification<\/em>\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Technology facilitates several different ways to verify modern customers. Many organizations use a combination of methods. The right approach can vary based on regulatory needs, industry verticals, etc. There are two major methodologies to know: passive and active verification. Passive verification does not engage the user and can involve techniques such as behavior analysis. Active verification can require individuals to submit information, such as selfies or ID documents.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em><strong>Method 1: Passive verification<\/strong><\/em>\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In passive verification, a user\u2019s proactive participation is unnecessary to confirm their identity. Passive methods use data analysis to determine if a user\u2019s behaviors and presentation match patterns known to belong to the authentic individual. Passive verification can also play a background role in active verification procedures, but not always.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This method could include reviewing patterns related to user interactions with a website, supposing the user makes the necessary allowances on their device. A passive verification may look at information such as:&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<ul class=\"wp-block-list\">\n<li>Known device information, such as the device\u2019s identification, operating system version, and the user\u2019s browser and its version.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Historical user account data to support identification of unusual transactions.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Behavioral patterns, like how a user swipes, taps, and navigates.\u00a0<\/li>\n<\/ul>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Unexpected differences from prior interactions or anomalous behavior raise a red flag and signal that the user might not be the genuine account holder. A customer identity verification API makes passive verifications a simple matter to conduct.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>Method 2: Active verification<\/em>\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In contrast, active verification requires users to engage in a process to confirm their identity.&nbsp; Users actively provide this information, which a business compares against a trusted and secure source of record. Some approaches to active verification include:&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<ul class=\"wp-block-list\">\n<li>Biometric verification, which may include fingerprint data, facial features, or even voice characteristics.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Document verification, which examines submitted documents such as a birth certificate or government-issued identification.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Video verification involving a user recording a short video or appearing live over a video link.\u00a0<\/li>\n<\/ul>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Even the collection of birthday information can be a form of active verification. Again, identity verification APIs can connect to the appropriate systems to verify that the supplied data or documents match the information in government databases.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Combining both methods at different times can provide <a href=\"https:\/\/www.telesign.com\/blog\/the-cost-effective-way-to-verify-users-and-increase-security%22%20%EF%B7%9FHYPERLINK%20%22https:\/\/www.telesign.com\/blog\/the-cost-effective-way-to-verify-users-and-increase-security\" target=\"_blank\" rel=\"noreferrer noopener\">the most effective methodology<\/a>&nbsp;&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"the-benefits-of-reliable-user-verification\"><\/span><strong>The benefits of reliable user verification<\/strong>&nbsp;<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">As you explore <strong>consumer verification services<\/strong> and how to set up <strong>secure customer onboarding<\/strong> in your business, consider the benefits your efforts can unlock.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>Security<\/em>\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cybercrime causes billions of dollars in losses every year. Fraud harms businesses and disrupts the lives of consumers. <a href=\"https:\/\/www.telesign.com\/blog\/id-fraud-affected-industries\" target=\"_blank\" rel=\"noreferrer noopener\">Identity theft<\/a> can have effects that last for years, and account takeovers can do far more damage than the spread of spam on social media. For example, an individual could lose their life savings if a takeover occurs with their bank account. Identity verification fights back against the full range of threats that challenge account security. Better solutions equal peace of mind for your business and customers.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>Compliance<\/em>\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In regulated industries, verification supports compliance. <a href=\"https:\/\/www.telesign.com\/glossary\/what-is-kyc\" target=\"_blank\" rel=\"noreferrer noopener\">Know Your Customer (KYC)<\/a> and anti-money laundering regulations are serious. Violations can be grave if your organization knowingly or unknowingly allows fraudsters to use your services. Fines for violations can stretch into hundreds or even millions of dollars. Avoiding such high financial risk is in your organization\u2019s best interest.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>Customer experience improvements<\/em>\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Innovative, reliable <a href=\"https:\/\/www.telesign.com\/blog\/the-full-sms-compliance-guide\" target=\"_blank\" rel=\"noreferrer noopener\">verification<\/a> procedures do more than provide peace of mind for your users. They also enable a more streamlined approach to processes such as onboarding. When a customer wants to place an order or do a financial transaction, verification that works silently in the background delivers a frictionless process users love. Sign-up processes for your service can become much faster and more reliable. They enable you to weed out potentially fraudulent account creation requests while letting your verified users through to the next stage.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em><strong>Controlled costs<\/strong><\/em>\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Robust<strong> <\/strong>customer verification API solutions ultimately lead to enhanced cost-effectiveness for your operations. Without the rapid capabilities possible through automation and modern technology, manual verification must occur instead. Especially for KYC\/AML procedures, such efforts can consume large amounts of time and effort. Manual workflows are often a significant source of human errors and mistakes that could lead to verification oversights. Technology accelerates the process, enhances confidence, and saves money\u2014all at the same time.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"top-challenges-in-consumer-identity-verification\"><\/span><strong>Top challenges in consumer identity verification<\/strong>\u00a0<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Verification is fundamental to safe, secure online transactions and proper compliance, but that doesn\u2019t mean it\u2019s always a simple process. Some challenges remain. Good technology, thorough plans, and a proactive focus on creating strong and reliable procedures can help address those challenges. First, you need to know what you\u2019re up against; here\u2019s a quick review of the three core areas of concern you\u2019ll need to navigate.&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<p class=\"wp-block-paragraph\"><strong>1.<\/strong><strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <\/strong><strong>Balance strong security with a good user experience: <\/strong>It is possible to create very secure verification processes that are very tedious or difficult to use. Users may not wish to return if they encounter too much friction and pushback in verification procedures. To strike the right balance, you need to make the verification procedure as fast, simple, and straightforward as possible from the user\u2019s perspective while the hard work of verification takes place almost invisibly.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2.<\/strong><strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <\/strong><strong>Know that verification solutions can\u2019t be static: <\/strong>Threats change constantly, and fraud tactics continue to grow more sophisticated. When bad actors learn how to defeat a verification method, fraud can run rampant. A proactive approach is vital; you must monitor changes in tactics and be ready to respond.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>3.<\/strong><strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <\/strong><strong>Keep an eye on compliance: <\/strong>Meeting the regulations in one region is not enough. Instead, you must have a system that can effectively achieve cross-border compliance with laws in the United States, the EU and elsewhere. From the General Data Protection Regulation (GDPR) to differences in KYC\/AML rules, your solution and its provider must understand how to protect your business from legal liability for noncompliance at every level.&nbsp;<\/p>\n<\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Telesign\u2019s <a href=\"https:\/\/www.telesign.com\/products\/verify-api\" target=\"_blank\" rel=\"noreferrer noopener\">Verify API <\/a>checks each of these boxes. It delivers seamless user verification via their preferred communication channels with automatic failovers to back up delivery methods when necessary. Telesign continuously updates its software and monitors the threat environment to change procedures when new fraud techniques develop. Telesign also has a clear and precise viewpoint on compliance to support customer verification in any region.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"digital-identity-verification-trends-for-2025\"><\/span><strong>Digital identity verification trends for 2025\u00a0<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Customer verification is a global priority, driving ongoing research and innovation to strengthen strategies. Emerging technologies and new solutions are shaping the present and future of identity verification. What key trends are influencing this space today?&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>AI and machine learning<\/em>\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even the most sophisticated systems and human intervention can\u2019t detect all the potential ways fraud can occur. Savvy threat actors and their technology or techniques can obfuscate and obscure fraudulent actions. <a href=\"https:\/\/www.telesign.com\/blog\/digital-trust-artificial-intelligence\" target=\"_blank\" rel=\"noreferrer noopener\">Artificial intelligence (AI)<\/a> and machine learning solutions currently lead the way in the fight against such problems.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With AI\/ML, it\u2019s possible to analyze hundreds or even thousands of potential signals and indicators pointing to the potential for fraud. Anti-fraud models can use large volumes of data to identify anomalous behavior and suspicious activity. As an always-on solution, AI never needs to take a break: it\u2019s always ready to monitor customer interactions and enhance the security of identification procedures. Over time and with more data, these models can become more adept at fraud detection.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>Blockchain applications<\/em>\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Blockchains and their immutable ledgers are a target of research and development in the identity verification space. Increased interest in decentralized identity management and the <a href=\"https:\/\/www.telesign.com\/blog\/fraud-digital-epidemic-part-two\" target=\"_blank\" rel=\"noreferrer noopener\">Self-sovereign Identity (SSI)<\/a> concept means more efforts are now concentrated in this area. In these applications, users maintain control over what elements of their identity they share with others.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Public and private key cryptography manages decentralized approaches rather than relying on a third-party organization to maintain such credentials. Issuers, such as governments or businesses, provide credentials to users and write information to the blockchain. When the user needs to verify their identity, they present the credentials of their choice to the organization, which can then check the blockchain ledger to confirm that the data matches and is unaltered. Blockchain applications may have a significant role in the future of zero-trust security environments.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>Behavioral biometrics<\/em>\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This trend pushes biometric identification to the next level. In traditional biometrics, a user\u2019s physical characteristics are a part of the verification procedure. It includes elements such as a user\u2019s fingerprint or face. However, in behavioral biometrics, systems examine how individual users interact with <a href=\"https:\/\/www.telesign.com\/blog\/the-importance-of-digital-identity-in-modern-businesses\" target=\"_blank\" rel=\"noreferrer noopener\">digital identity environments<\/a>. Rather than fingerprints, this methodology might consider the patterns present in the way a user types, how someone navigates a website or app and even how they swipe around a touchscreen. These can all provide signals for behavioral analysis.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When a system detects that a user\u2019s behavioral biometrics don\u2019t match expected patterns, it can flag potential fraud. Substantial differences might lead to an additional verification challenge or even the removal of access to a system. In combination with AI and other technologies, this next generation of biometrics may have a central role to play.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With Telesign solutions, businesses can tap into cutting-edge customer verification solutions. We continuously invest in improvements and innovations, including incorporating AI\/ML into products such as <a href=\"https:\/\/www.telesign.com\/products\/intelligence\" target=\"_blank\" rel=\"noreferrer noopener\">Intelligence<\/a> and <a href=\"https:\/\/www.telesign.com\/products\/verify-api\" target=\"_blank\" rel=\"noreferrer noopener\">Verify API<\/a>.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"the-role-of-apis-in-customer-verification\"><\/span><strong>The role of APIs in customer verification<\/strong>\u00a0<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">So far, we\u2019ve discussed the basics of customer verification and mentioned the usefulness of APIs in this process. Let\u2019s focus on these software applications and how they provide the framework for modern customer verifications.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>What is a customer verification API?<\/em>\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An application programming interface (API), at its most basic level, is a way to bridge the gap between different software, servers, and systems. APIs facilitate the secure passage of information back and forth between systems to power a wide range of functionality. A customer verification API provides a means to integrate different methods to verify a user\u2019s identity when interacting with a business online. An API facilitates the collection of identity information and communicating that information for verification purposes.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let\u2019s consider a simple example. A user wants to log in to their account. Yet, you need to be sure that a user who has enabled multifactor authentication is the right person.&nbsp; The user\u2019s login attempt triggers an event that sends a one-time code to that user\u2019s device through the API. When the user enters their code, the data flows back through the API which validates the result.&nbsp; Upon confirmation of identity, the user can access the account.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are other ways to use an API for identity verification,<strong> <\/strong>too. For example, banks and institutions subject to KYC\/AML regulations may use a document verification API to handle a user submission of an item such as a scanned driver\u2019s license. The API could extract that information, communicate with a database that can confirm its validity, and return the result to the business.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">APIs can facilitate multiple approaches to verification based on circumstances and needs. Aside from using SMS to send a one-time password, a verification API could also send validation emails, collect and confirm matches between biometric data, and more. Advanced solutions can integrate with machine learning and AI models for enhanced fraud detection. Just one API, such as <a href=\"https:\/\/www.telesign.com\/products\/verify-api\" target=\"_blank\" rel=\"noreferrer noopener\">Telesign&#8217;s Verify API<\/a>, can provide connections to multiple channels and verification methods.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>What are the benefits of API usage?<\/em>\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Using an API for customer verification offers benefits that can prove valuable to modern organizations, not just because they simplify compliance.

Further significant improvements are likely to occur in the near and long term. AI already impacted the customer identity verification process considerably. As intruders become more sophisticated, the deep learning and analytical capabilities of AI models will be a valuable asset in the effort to close off potential attack vectors. How can AI help?&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AI\/ML models can ingest massive amounts of data and learn to detect patterns based on many details. Even in a simple identification procedure, an AI model can monitor many information signals to support better customer verification. What are some of the more specific features AI offers?&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AI models can learn how users usually behave and interact with an organization. When those behaviors don\u2019t match the model\u2019s expectations, it can flag such actions as an anomaly. With greater confidence, an AI model may even designate actions as threats and trigger events that lock down and secure an account or restricted resources. &nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Events that could raise flags include log-in events from unusual or remote locations, sudden high-value transactions or even deviations in standard purchase patterns. Humans can\u2019t easily detect these patterns, but an AI trained to detect fraud can find them rapidly.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AI can also enable predictive analytics to look at factors that indicate a higher risk of fraud even before a user completes an action. High-risk users can include brand-new accounts, accounts with <a href=\"https:\/\/www.telesign.com\/blog\/5-easy-password-best-pratices-to-protect-yourself-from-a-hack\" target=\"_blank\" rel=\"noreferrer noopener\">recently-changed passwords<\/a> and accounts accessed from a new location. Sudden changes in shipping or billing information or transactions with an unusually high total can also be a red flag in AI analysis.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The real-time nature of such analysis is the most valuable part of AI applications. These solutions can process verification data and flag risky behavior nearly instantly. The sooner you can identify and stop potential fraud, the better your organization can protect itself.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"best-practices-for-user-verification-implementation\"><\/span><strong>Best practices for user verification implementation<\/strong>\u00a0<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">What does it take to successfully implement a new customer verification API?
