Amid the rising tide of impersonation scams and sophisticated deepfake technology, it’s easy to despair of ever keeping the cyber criminals at bay.

But, according to an online security expert, the answer could lie in a simple password.

Not, however, any old computer password but one created to help family and friends identify whether they are interacting with a person they really know or an AI-generated deepfake.

Cody Barrow, a former US government adviser, said artificial intelligence has made impersonation scams easier to create.

He added that AI was helping to ‘lower the barrier to entry’ for cyber-criminals and extra precautions beyond basic online security were needed to combat it.
