A reference guide for developers and compliance teams. This glossary defines the key terms you'll encounter when building with LumiID. It covers identity verification, KYC and KYB processes, fraud prevention signals, AML screening concepts, and LumiID platform terminology. Whether you're a developer integrating the API or a compliance team member reviewing verification workflows, use this page as your reference for consistent, accurate language. *** ## Authentication and Platform Terms > [accordion] Application > > A registered project in the LumiID Dashboard that represents your integration. LumiID creates an application automatically when you create an API key. > [accordion] API Key > > A private credential used to authenticate LumiID API requests. Each API key belongs to an application and can be regenerated from the LumiID Dashboard. Never expose an API key in client-side applications or public repositories. > [accordion] Sandbox > > A testing environment where you can develop and validate your integration without affecting production data. > [accordion] Production > > The live environment used for processing real customer and business verification requests. > [accordion] Webhook > > A secure HTTP callback that allows LumiID to notify your application in real time when events such as completed verifications or asynchronous processes occur. *** ## Identity Verification > [accordion] Identity Verification > > The process of confirming that an individual is who they claim to be using trusted government or financial data sources. > [accordion] KYC (Know Your Customer) > > A regulatory process that verifies a customer's identity before granting access to financial products or services. > [accordion] NIN Verification > > Validates a Nigerian National Identification Number (NIN) against official identity records. > [accordion] BVN Verification > > Verifies a Bank Verification Number (BVN) to confirm an individual's banking identity. > [accordion] Face Match > > Compares a user's selfie with the photograph associated with a government-issued identity document to determine whether they belong to the same person. > [accordion] Liveness Detection > > Confirms that a real person is present during identity verification and helps prevent spoofing attacks using photos, videos, or masks. > [accordion] Identity Lookup > > Retrieves verified identity information from trusted government or financial databases after successful verification. *** ## Business Verification (KYB) > [accordion] Business Verification (KYB) > > Know Your Business (KYB) is the process of verifying a company's legal identity before onboarding or conducting business with it. > [accordion] CAC Verification > > Verifies a business registered with Nigeria's Corporate Affairs Commission (CAC) and retrieves official registration details. > [accordion] TIN Verification > > Confirms the validity of a Tax Identification Number (TIN) issued to an individual or business. > [accordion] Director Verification > > Validates the identities of company directors or business representatives during business onboarding. > [accordion] Ultimate Beneficial Owner (UBO) > > The individual who ultimately owns or controls a business, even if ownership is held through other entities. *** ## Fraud Intelligence > [accordion] Fraud Intelligence > > LumiID's risk analysis capabilities that help businesses identify suspicious identities, fraudulent activity, and high-risk behavior throughout the customer lifecycle. > [accordion] Fraud Score > > A numerical risk score generated by LumiID that estimates the likelihood of fraud based on multiple identity and behavioral signals. > [accordion] Identity Risk > > An assessment of the overall trustworthiness of an identity using verification results, behavioral analysis, and historical patterns. > [accordion] Device Intelligence > > Collects device attributes to help identify suspicious devices, repeat fraud attempts, and device sharing across multiple accounts. > [accordion] Behavioral Signals > > User activity patterns analyzed to identify unusual or high-risk behavior during onboarding or ongoing account usage. > [accordion] Velocity Check > > Measures how frequently an identity, phone number, device, IP address, or business appears within a defined period. High velocity may indicate fraud. > [accordion] Watchlist Screening > > Checks individuals or businesses against sanctions lists, politically exposed persons (PEPs), enforcement records, and other regulatory watchlists. > [accordion] Case > > A verification or fraud event that has been flagged for manual review within the LumiID Dashboard. *** ## API and Platform Concepts > [accordion] API Request > > A request sent from your application to the LumiID API to perform a verification or retrieve information. > [accordion] Endpoint > > A specific URL that provides access to a LumiID API service, such as NIN verification or business verification. > [accordion] Customer Reference > > A unique identifier you supply with an API request for tracking transactions in your dashboard and API logs. Examples include customer IDs, invoice numbers, or transaction IDs. > [accordion] Verification ID > > A unique identifier assigned by LumiID to every verification request for auditing, troubleshooting, and support. > [accordion] Response > > The JSON data returned by the LumiID API after processing a request. > [accordion] Rate Limit > > The maximum number of API requests your application can make within a specified time period. > [accordion] Confidence Score > > A numerical value indicating how confident LumiID is in a verification result or biometric match. > [accordion] Audit Log > > A chronological record of API requests, verification attempts, and system events available for monitoring and compliance purposes. *** ## Compliance and Privacy > [accordion] NDPA Compliance (Nigeria Data Protection Act) > > LumiID is designed to support organizations operating under the Nigeria Data Protection Act (NDPA) by enabling secure processing and handling of personal data. > [accordion] Personally Identifiable Information (PII) > > Information that can identify an individual, such as a name, phone number, National Identification Number (NIN), or Bank Verification Number (BVN). > [accordion] Data Encryption > > The process of protecting sensitive information while it is transmitted between your application and LumiID or stored within the platform.
