What is a presentation attack and how does it impact ID verification?

Plastic surgery, identity theft, or using fake biometric data are just a few examples of how presentation attacks can occur. Presentation attacks happen when someone uses another person's physical characteristics to impersonate them in order to gain access to their accounts or services. To combat this type of fraud, biometric verification is used which compares a person's physical characteristics to verify their identity. However, the risk of presentation attacks grows as more people complete identity verifications online and identity thieves become more sophisticated. To mitigate the risk of presentation attacks, robust protection is needed, including verifying identities across authoritative data sources, documents, and liveness. Plaid Identity Verification uses advanced image processing and machine learning to combat fraud by detecting pixel changes, deep fakes, masks, and more. It also offers a conversion-optimized funnel to reduce risk and improve new user sign-up rates. The solution balances security with user convenience and is optimized for secure online identity verification processes.
