While emerging AI technologies bring increasing challenges in detecting bad actors, and concern from your consumers, the reality is that most of your callers are good callers. The customer experience for legitimate callers should not be punished as a side effect of efforts to find the fraudsters in the haystack. That’s why we keep innovating Pindrop’s Authentication features to provide a range of high confidence multi-factor authentication signals over the length of a call. Immediately available validation like ANI Validation lets you route calls based on risk right from the beginning, reducing friction for low risk callers and increasing friction for higher risk ones. This method is proven with almost 90% of Passport customers, and results in reduced friction on over 90% of calls on average. Now, there’s a solution to leverage audio alone to expedite call handling with Audio-Based ANI Validation.

The Pindrop team has been beating our drum on, and proving, the benefits of ANI Validation for a long time. We’ve invested in our ability to offer this critical component of device validation via in-house development, integration with key partners like Verizon, and acquisition of device verification pioneer NextCaller. And now there’s more! In our quest to constantly continually innovate authentication within our scalable cloud-based solutions, we’re excited to announce a new feature that expands access to this powerful authentication signal by relying on something every call has – audio. 

With Audio-Based ANI Validation, you’re able to:

  • Validate caller ANIs and spoofing risk through call audio
  • Achieve more advanced security by offering multi-factor ANI Validation when carrier data and call audio are present
  • Integrate seamlessly with other authentication feedback to provide one single score and tiered authentication policies housed in one unified platform

With this new feature, up to 84% of calls can be verified using audio alone. Call validation increases to as high as a 92% verification rate when combined with existing ANI Validation methods. In 2024, our team is on track to expand this to four validation factors targeting a 95%+ verification rate — taking the work off of your call centers and not frustrating your callers throughout the process. 

How does Audio-Based ANI Validation work?

Audio-based ANI Validation allows Pindrop’s Passport solution to determine whether a call is spoofed with access to just seconds of call audio. This new spoof detection method provides an alternative to methods requiring call metadata, which many customers struggle to acquire consistently from their telephony carrier, or the third party integrations many of our competitors rely on. 

The Pindrop research team discovered, defined, and then built this new detection method no one else offers. It greatly expands the number of customers able to receive this scoring, including our international customer base.

“The Authentication Research team’s goal this year was to expand the availability of our Authentication platform, including foundational ANI validation, to new customers, markets, and geographies. We quickly realized the need for a new technology not limited by metadata that few customers have. I am so proud that my team could think beyond what is standard in the market today and innovate this audio-based method, which leverages a fundamental component of the call that is always available, everywhere. In 2024, we’re delighted that every Pindrop customer will have access to the value that ANI validation provides.” – Kailash Patil, Director of Research
