Digital identity trust company Daon has partnered Neustar to provide an integrated solution for deterministic authentication through automatic number identification (ANI) validation. The solution is designed to reduce fraud and mitigate call spoofing,  a method of scamming that undermines trust in the caller ID process.

Daon will add Neustar Authentication Plus and Account Link solutions to its IdentityX library of biometric algorithms. These solutions provide a deterministic and probabilistic device and phone number identity proofing before the call is connected, providing contact centres with the ability to offer a frictionless authentication experience. By integrating Neustar’s communication solutions, phone calls and devices used to make those calls will undergo real-time inspection to ensure accurate, secure caller-to-agent contact through ANI validation and ANI match.

Neustar solutions leverage both ANI validation and matching to validate whether a call is coming from the device that owns the number or via a phone number match to a referenceable database. The process is completed almost instantly as calls reach the IVR through a passive process that doesn’t require active participation by the caller. According to YouMail’s Robocall Index, in May 2022, call spoofing averaged 4.

1 billion calls a month over the past year, equating to about 1,500 calls per second. Criminals often use call spoofing to replace their calling number with the number of a real customer. ANI matching and ANI validation work together to ensure a spoofed number will not be matched to a customer’s account.
