Security News > 2021 > July > Combating deepfakes: How we can future-proof our biometric identities

How worried should we be about deepfakes? What sort of threat do they pose to digital ID verification and the biometric technology that we are becoming so reliant on, and are there ways to combat the threat?

While video deepfakes are arguably the most common, audio deepfakes are also growing in popularity.

You've probably seen some of the more prominent deepfakes that are out in the public domain right now - notably those manipulating existing footage of Obama and Tom Cruise.

As shown in the unfortunate deepfake scam above, cybercriminals have started to use the technology for perpetrating fraud and there is now concern that the technology can and will be used to develop fake biometric identifiers to bypass biometric-based fraud prevention solutions.

To secure our biometric identities against a deepfake threat, we need to have the agility to evolve and add more or different factors as the threats change and become more sophisticated or more available.

A deepfake attack that passes the biometric check is unlikely to be able to replicate a required action, as such pre-determination is impossible with the processing power available today.
