What are the Most Common Methods Used to Verify Identity?

There are six common methods of verifying an identity. These are:

  • Biometric verification: Cross-checks a selfie against a person’s ID to make sure they are the same person
  • Database methods: Cross-references databases like the Internal Revenue Service (IRS), credit bureaus, social media, etc to verify a person’s identity
  • ID document verification: Scrutinises the ID given (passport, driver’s licence, etc) to ensure it is legitimate
  • Knowledge-based authentication (KBA): Asks questions to the user based on information provided by third party verification platforms. These can be static, dynamic or customer-based questions
  • Liveness detection: Detects legitimacy of a selfie against spoofing, etc
  • Two-factor authentication: Requires the user to provide two (or more) verification factors before accessing an application or online account. These additional verification factors include an email address or phone number.

What is the Best Method to Validate an Online Identity?

Based on your business there can be a variety of best methods to use for identity verification. If your customers are low risk liveness detection or ID document verification could be enough if you. If your business is at high risk of fraud, database methods, knowledge-based authentication or two-factor authentication may be necessary to conduct business safely.
