Scientists are using your heart as a security authenticator
In the wake of serious security breaches in the last year, from the pilfering of Target customers’ credit card information to the celebrity iCloud selfie-hack, it’s easy to feel digitally naked. Your current best options—like making your password something along the lines of “**_^XBE47>>” or using two-step verification—also have their shortcomings, which has inspired a crop of enterprising scientists to come up with what must be the oddest, and possibly most secure, password yet: the rhythm of your heart.
A team of Toronto scientists has developed a wristband that can use your own heart rhythm, as measured by electrocardiograms (ECG).
