Inclusive security using voice biometrics and Microsoft Identity

Inclusive security for the visually impaired, those with difficulty reading or understanding a language, or don’t have access to a dedicated personal device

WhoIAm-Logo

This is the fascinating use case for which our partner WhoIAM has been using our voice biometrics technology. This has just been featured in the latest edition of the Microsoft Azure Identity partner integration video that uses our speaker biometrics-based authentication to make identity security design more inclusive. We at Oxford Wave Research support this laudable goal all the way!



As Ajith Alexander,  head of product management at WhoIAM, writes in the Microsoft Azure AD identity blog:

ajith3

“Using voice biometrics for verification is also a powerful tool for implementing inclusive security. Human voices are readily available, can be recorded in a contactless way, and do not require specialized hardware. Our voice carries an imprint of our identity that comes through regardless of what we’re saying, what language we’re speaking, or where we’re speaking from. This makes voice biometrics an ideal choice for catering to users who are visually impaired, have difficulty reading or understanding a language, don’t have access to a dedicated personal device (residents at assisted-living communities, shift-workers), or live in less developed areas that rely on fixed phone lines. …Creatively solving for flexible, inclusive user verification ensures we can log in previously marginalized customers securely without identity verification being a frustrating experience.”
