What if you could break into the contents of a locked box with only the power of your voice? If that seems a little farfetched, the reality is that many security systems use \u201cvoice biometrics\u201d \u2013 the sound of a person\u2019s voice \u2013 as a key to unlock valuable content, including our money, healthcare records, and billing accounts. Some banks, for instance, authenticate a caller\u2019s identity by comparing them saying, \u201cMy voice is my password\u201d to a version they hold on file. If the two samples match well enough, the individual passes that verification task, and may even be granted full access to the account. But in this age of deepfakes and voice clones, should we be relying on these kinds of systems? How robust are they? And when is it too soon to start thinking about AI, security, and privacy?<\/p>\n
